Planning Notes

Heat Pumps, General Information

Planning and installation must becarried out in compliance with therelevant rules and regulations (SWKI,SIA, AWP, VDI 4640, etc.).

Prior Clarifications / ApprovalsIt is recommended to clarify thefollowing items early on in the planningphase:

With electric company:- Connection permit- Starting current- High/low/special rates- Blocked times

Heat sources:Water extraction from public watersand the positioning/repositioning of ageothermal probe or tube collector must be approved by the respectivelyresponsible local office or authority.This is usually the Office of Energyand Water Management or Environ-mental Protection Agency (indicatecoordinate of house location).

Heat Pump DimensioningCompared with other heat generators,

the heat pump has a smaller applica-tion scope. The heat output and therequired power and with that the utili-zation ratio of the heat pump varydepending on heat source and heatutilization temperatures.

A basic principles applicable herestates that the smaller the differencebetween heat utilization and heatsource temperature the more efficient(better performance number) thesystem can be operated. This is whythe planner/installer of the heat pumpmust take boundary conditions intoaccount.The system must be configured anddimensioned in such a way that usagelimits are not exceeded.

Water HeatingIn addition to heating rooms, a heatpump can also be used to heat water.This makes sense since the energysavings are considerable comparedwith electrical water heaters.

Depending on the refrigerant used,different max. hot water temperaturesare reached (50°C - 60°C). These arethe result from the operating limits of therefrigerant as well as the structure of the cooling circuit of the heat pump.Water is heated indirectly with thefollowing typical solutions:- Coil storage tank- Combination storage tank (heat

storage with integrated boiler) or Spira storage

- Storage with external plateexchanger (Magro system)

When selecting coil or external platestorage tanks, it is especially importantto make sure the heat exchanger surface is sufficient. This requires takingwater volume, temperature differences,as well as heat pump capacity intoconsideration. A combination with solar collectors is quite possible. using asuitable water heat, e.g. a combinationstorage tank, it is possible to heat water entirely with solar collectors, especiallyduring the summer.

Buffer Storage Always make sure the entire output of the heat pump is always acceptedregardless of the type of storage installa-tion.Integrating a technical storage or heat storage tank is generally recom-mended.It ensures optimal operatingconditions such as the following:

• Output excesses of the heat pumpare absorbed

• Bridging EC off periods

• Enables several heating circuitConnections

Buffer storage tank should be omittedonly in the following cases:

• If the heating water volume isgreater than 25 liters per kWheating output or with a goodstorage capability of the heatemission system (floor heater configured < 40 °C)

• No thermostatic valves

t =V * c * Δt

Qh * 60

V = Tank volume in liters

Qh = Heat demand in watt

t = Bridging time in minutes

c = 4187 W/s

Δt = Temp. difference, heating circuit

Circulating PumpsThe evaporator and condenser flowvolume specified by the heat pump(HP) must be adhered to consistentlyto configure and dimension thecirculating pumps. Speed-controlledcirculating pumps may not used for the thermal emission of the HP.The heat source pumps (brine/groundwater) must be suitable for usewith cold water. The viscosity of theheat carrier medium must be considered when configuring the system.

Overflow ValveIn case of heating systems withvariable or hot water flows that can beshut off (e.g. thermostatic valves) andserially installed storage tank, an over-flow valve must be integratedupstream of the circulating pump.This ensures the min. flow of heatedwater and prevents frequent switching,which may lead to malfunctions.The overflow valve must be set anddimensioned properly.

The size of the buffer storage dependson the max. heat output and the max.permissible activation frequency of theheat pump.

A general reference value is approx.30 lto 50 liters per kW heat output.For an increased buffering also more.

For the coverage time (withoutconsidering the internal storagecapacity of the heating system) of theheat demand using a buffer storage,e.g. in case of an EC off period or outage, can be calculated as follows:

Planning Notes

Heat Pumps, General Information

TransportNever tilt the heat pump beyond max.30º (in any direction) when trans-porting it. Avoid exposing the heatpump to any type or degree of mois-ture or humidity.Protect the heat pump from damageduring all construction phases.

SetupThe heat pumps can be set up on asmooth, level, and plane surface with-out the need of a base or pedestal.The installation room must be dry andfrost-free. Rooms with much humidity

such as laundry rooms, etc. are notvery suitable for installing the heatpump. The min. clearances must beadhered with for all equipment toensure access in case of maintenanceand control tasks.

The heat pumps should never be setup on a floating floor.

Heater Room VentilationDue to the low heat emission of theheat pump, the heater room remainspractically unheated. To prevent high

levels of humidity in the room thatmay damage the equipment, install anon-closable vent of at least 100 cm

2.

Noise EmissionsEquipment-borne noise transferredto the heating system, electrical cable,and the building can be avoided byusing flexible connections throughout:

• Tubes/hoses for pipe and ductconnections

• Flexible electr. connections

• With wall openings, avoid direct

contact of pipes and ducts withwalls

• Anti-vibration fasteners

AQUATOP T heat pumps runextremely quiet, thanks to the noise—dampening insulation of the claddingas well as the multi-dampened supportof the cooling circuit.

Hydraulic IntegrationWe offer different hydraulic standardschemes for each heat pump. Integra-tion based on these variants ensurestrouble-free and secure operation.Before connecting the heat pump, theentire piping of the system of new andold equipment alike must be thoroughly

flushed. Residues left in the heatingpipes, ducts, or the borehole heatexchangers / geothermal tube collec-tors may cause damage to theheat exchangers and HP malfunctions.We recommend using a dirt trap in theheat return.

The fill-up water of the heat systemmust be treated according to the re-gulations of the professional associa-tions.

A complete ventilation is important

since Otherwise the correct operationof the heat pump is affected. Accordingly an exhauster must beused. With compact heat pumps anexhauster is installed on the flow.

Electrical ConnectionFuses must be used with the heatpumps in accordance of the enclosedconnection diagram and connected tothe definite house connection line(no disruptions of electrical supply dueto construction work, phase change).Do not carry out a trial run after completing the wiring work.The heat pump is to be protectedelectrically from startup by unaut-horized persons.

Electrical connection work must becarried out by a licenses technicalexpert.

Initial StartupThe initial startup must be carried outby qualified technicians or the warrantywill become void.The installed heat pump should not bestarted until all steps of the installationprocess have been completed.The technician in charge of the initialstartup (commissioning) is not an installer or planner and can only completehis or her job successfully if all systemparts are complete and all planningvalues needed to configure the systemare available.

Initial startups are carried out only onheat pumps that are:

• completely filled on the water sideand vented (heat source, heater)

• equipped with a definite electricalconnection line

• and in the presence of the by anelectrician or heating system installer

• completely wired (sensors, drivesetc.) according to the designatedsystem scheme.

Since an overload may cause severedamages to the heat pump as well asthe heat source system, operating thepump under the following conditions isprohibited:- Construction drying- System/unit used in unfinished

buildings- Windows or exterior doors not

yet lockable or still uninstalled.In this case a temporary constructionheating should be used.

If the conditions listed above are notmet, the initial startup cannot be carriedout. We reserve the right to invoice the

associated costs.

The warranty for heat pump damagesbecomes null and void in case of noncompliance with these planningnotes or the corresponding operatingand assembly instructions.

Basic Principles for Configuring Geothermal Probes

Basic Principles for OperatingGeothermal ProbesThe possible load of a geothermal probedepends primarily on the subsoil/rockand the borehole depth. Some deepborehole heat exchangers yield a better annual performance factor of the heatpump system than some less deepborehole heat exchangers with the sametotal length. The geographic region of the building's location must be consid-ered as well.

If properly configured and implemented,a geothermal probe can have a service

life of up to 100 years.

Output and load of geothermal probesThe following specific dimensioningvalues have proven to be effective for smaller systems up to approx. 4 to 6"not encapsulated" probes:(normal subsoil; cf. VDI 4640)- 100 kWh/m/year max. heat extraction- 50 kWh/m/year max. specific probe

extraction capacity

Larger probe fields must be checkedwith a simulation calculation for correct

dimensioning.

Effect of Depth and Diameter Borehole heat exchangers positionedlower permit a higher specific outputwhile maintaining the same mediansource temperature or a higher mediansource temperature while maintainingthe same total length.The soil or rock temperature increasesby approx. 1°C every 30 m of depth.Deep borehole heat exchangers,however, have a higher flow resistance.Optimization thus must be achievedbased on the type of system used(number of probes, heat sourcetemperature, performance rate of heatpump, brine pump coefficient).

Basic Principles for Configur ingGeothermal ProbesLocal Norms and regulations mustalways be considered and have prioritylike the for Switzerland valid SIA 384-6

The collector lengths indicated in thedocumentation affect the followingbasic principles:The indicated lengths refer to thefollowing basic principles:- Monovalent operation- Extraction capacity 45W/m- Approx. 1800 hrs/year (max.

2000 operating hours/year)- Annual extraction energy approx.

90 kWh/m/year (max. 100 kWh/ m/year)

- Mid-level altitude up to approx.800 m above sea level

The collector lengths are to be adjustedin case of the following systemconditions:- Bivalent operation (extracted

energy max. 100 kWh/m/year)- Higher operating hours (>2000),

e.g. in mountainous regions- High hot water demand(Sum of extracted energy max.100 kWh/m/year)

- Pool water treatment

Basic Principles for Configuring GeothermalTube Collectors

Description of Geothermal TubeCollectorsContrary to borehole heat exchangers,tube collectors are installed verticallyat a depth of approx. 1.0 – 1.5 m.Continuous pipes with a diameter of 20 to 40 mm are used for the tubecollectors. These pipes are installed inthe soil or rock horizontally and tubular-shaped at a distance of 0.6 to 0.8 m.Polyethylene pipes are a preferredmaterial. This material has the neces-sary elasticity and favorable flowcharacteristics as well as low frictionlosses. For this type of utilization, they

are corrosion-proof and nearlyindestructible. They have a service lifeof approx. 50 years.

Max. Extraction Capacity of Geothermal Tube Collector SystemsThe following soil or rock propertiesare especially important for the proper dimensioning of the installation area:

• k-factor/thermal conductivity(W/mK)

• •Specific heat (kJ/kgK)

• Density (kg/m3)

These three parameters are primarilyaffected by the humidity content of thesoil or rock. Normally, the soil can beexpected to be moist. Practical applica-tion requires only the followingdifferentiation:

Humidity content of soil:

• Wet

• Moist

• DryThe wetter the soil, the better the heattransfer ratios.

Soil consistency:

• Sandy

• Loamy

• Rocky

Global sunlight levels:

• Sunny

• Normal

• ShadyHumidity content, soil consistency, andsunlight levels are to be weightedaccording to their direct effect.

In Central Europe, the followingconstellation usually applies:

Moist/sandy/normalThe following max. extraction capacitiescan be assumed based on this constel-lation and collected experience:15 - 20 W/m2

If the weighting of the influencing factorsuncovers a constellation with valuesbelow the normal ones, the heat ex-traction per m2 of soil area must bereduced. In case of unfavorable condi-tions, e.g. stony-dry-shady, the following

value is surely all that can be expected:10 - 15 W/m2

If the soil can be characterized as moistand loamy, the following value can beexpected:20 - 25 W/m2

Basic Principles for Configur ingGeothermal Tube CollectorsThe collector lengths indicated in thedocumentation affect the following basicprinciples:

The indicated lengths refer to thefollowing basic principles:- Monovalent operation only for room

heater - Extraction capacity 20W/m2

- Approx. 1800 hrs/year (max. 2000operating hours/year)

- Annual extraction energy approx.40 kWh/m/year (max. 50 kWh/ m/

year)- Mid-level altitude up to approx.

800 m above sea level

The collector lengths are to be adjustedin case of the following systemconditions:- Bivalent operation (extracted

energy max. 50 kWh/m/year)- Higher operating hours (>2000),

e.g. in mountainous regions- Water heating (sum of extraction

energy max. 50 kWh/m/year)chapter)

Pool water preparation, longer operating hours, bi valent systemsWe recommend not to configure thesetypes of systems with tube collectorssince the soil or rock cannot be deter-mined with certainty, which poses therisk of an overload of the ground.Please consult leaflet No. 43 of theBDH from May 2010 for additionalinformation.

Planning Notes

Basic Principles for Configuring Geothermal Probes

Thermal Insulation All lines, pumps, and valves must beequipped with cold insulation materialas a protective seal from vapor diffusion (install drip pan, if necessary).

Connection Lines and Distributors- Select the shortest line distance

possible- Dig trench for connection lines

down to frost penetration layer, if possible with a slight inclinetowards the borehole heatexchanger

- Make sure the brine trench allows

water to penetrate through, fill withsand, dewater if needed

- Embed connection pipes in sandlayer (risk of damage)

- Do not cover until a pressure testhas been conducted

- Fill system according to theTechnical Datasheet AWP

Exterior Installation- Make sure distributor is accessible- Seal wall openings and heat

insulation to protect from water

Interior Installation- Install drip pans if needed- Avoid equipment-borne noise

Transference

Heat Source Booster PumpBecause the median temperaturedifference, the flow rate, and thematerial properties of the used heatcarrier fluid (water-antifreeze mixture)also play a decisive role, the di-mensioning of the heat source booster pump must also be carried out verycarefully. In addition, the annual per-formance factor of the system can beaffected significantly due to the highperceptual share of the electrical inputof the heat source booster pump,especially with smaller systems.The brine circuit of the borehole heat

exchanger must be calculated carefullyconcerning the flow volume and pres-sure losses.The line installation and dimensioningas well as the probe lengths andnumber must be optimized in referenceto the system.Only then is it possible to determine theright heat source booster pump for thesystem. The large difference of thehydraulic coefficient must also beincluded in the dimensioning processfor the booster pumps available inmany different sizes.

The integrated brine pump of compactheat pumps must be checked to ensureit is suitable for the application at hand.

Planning Notes

Brine-Water Heat Pumps

Appl ication RangeBrine-water heat pumps are usuallyused as monovalent heaters.If the heat pump and the borehole heatexchanger have been dimensionedcorrectly, geothermal energy providesa relative constant heat source with agood performance rating.

Monovalent OperationIf the heat pump is used in a monova-lent manner (without auxiliary heater),the following basic data must becarefully determined and calculated:

• Determine heat capacity demandacc. to local standards (SIA 384/2,DIN 8900-6, DIN 8901) or deter-mine based on the previousenergy consumption.

• Max. required flow temperature of heating system.

The heat pump must deliver 100% of the required average building capacityat the lowest exterior temperatures andmax. flow temperatures.

Bivalent OperationIf the heat pump is used in a bivalentmanner (with auxiliary heater), thefollowing data must be carefullydetermined and calculated:

• Determine heat capacity demandacc. to local standards (SIA 384/2,DIN 8900-6, DIN 8901) or deter-mine based on the previousenergy consumption.

• Max. required flow temperature of heating system.

• Determine the bivalent point(switchover point).

The auxiliary heater is usuallydimensioned for 100% capacity.

When used in a bivalent-paralleloperating mode, the borehole heatexchangers must be dimensioned byan accredited engineering office.

Permits A permit for the utilization of geothermalenergy must be obtained from thelocally responsible office or authority.Each connection of an electricheat pump requires a permit of theresponsible electric company or utility.The electrical heat pump data must beknown for the application.

Borehole Heat Exchanger The annual performance factor of aheat pump (HP) is affected by theconfiguration and dimensioning of theborehole heat exchanger (BHE).

Dimensioning requires taking intoaccount the cooling capacity of the HPat the configuration point, the serviceduration per year, the geology, theposition, layout, and depth of the BHE.The standard reference points is asfollows: cooling capacity at B0 /W35(brine inlet temp. = 0°C,flow temp. = 35°C) is assumed.The general borehole and installationconditions of the drilling company mustbe observed when positioning geother-mal probes.For further information see chapter

‘Basic Principles for ConfiguringGeothermal Probes’.

Thermal Recovery Time of the SoilThe annual heat pump operationshould not exceed 1800 hours per year. If the number of operating hoursis higher, the borehole heat exchanger must be dimensioned larger.

If service water is heated year-round,the, borehole heat exchanger lengthmust be increased according to the hotwater demand so that a sufficientamount of energy is replenished fromthe surrounding soil or rock to the BHE.This applies especially with well insu-lated buildings (low energy) wherehot water heating takes up a largeshare of the annual energy demand.

Brine Heat Carrier The brine circuit requires the use of non-polluting antifreeze agents (e.g.

Antifrogen N).Compliance with the concentration of 20 - 30 vol. % is required and must bechecked periodically. The boreholeheat exchanger must be filled accordingto the operating instructions. If anti-freeze is added to a system subse-quently, it cannot be guaranteed thatantifreeze and water are mixed properly.Flush the pipe system before filling inthe heat carrier fluid. Never use air toblow out the BHE. It must be filled with

fluid at all times. Pollutants may causedecomposition of the heat carrier media.This results in sludge, or the pollutantitself may damage the heat exchanger (malfunctions) and other components.

Connection LinesHeat SourceThe material compatibility of the lineswith the antifreeze agents must bechecked (no galvanized lines).Connection lines must be kept as shortas possible. Condensation forms on

lines and fittings in warm rooms.This must be prevented with vapor proof insulation material or collected with adrip tray. The installation must beprotected from corrosion (materialselection).To be able to detect leaks, a pressurecontroller must be installed in the brinecircuit for monitoring. It must be possibleto shut off each borehole heat exchanger individually from the point of the distri-butor.

Water-Water Heat Pumps

Appl ication RangeWater-water heat pumps are usuallyused as monovalent heaters. The hightemperature level of the water sourcesyields high performance figures.The type of utilization of this heatsource depends on the chemicalcomposition of the groundwater or surface water. the source temperature,as well as the general applicable rulesand regulations.

Direct utilizationWith this type of use, the temperature

level can be fully utilized.Direct utilization of natural bodies of water (e.g. lakes, river water, ground-water) is not permitted since naturalbodies of water may lose their qualityover time and represent a constant riskof corrosion. Direct utilization is re-commended with closed circuits with aconstant water quality that can bemonitored and which corresponds withthe quality found in heating or coolingsystems.The factory warranty becomes null andvoid in case of direct utilization of natural

bodies of water.

Indirect UtilizationThe utilization of surface waters (river,lake, creek water) usually does notpermit monovalent operation withdirect utilization due to the relativelyhigh temperature fluctuations of thesewaters. The heat exchanger in theintermediate circuit required for indirectutilization must be made of corrosion-resistant Please note that the inter-mediate circuit temperature may dropbelow 0ºC depending on the heatsource (frost-protection in intermediatecircuit).

The concentration of the heat carrier inthe intermediate circuit therefore mustbe configured for the lowest possibleevaporation temperature (recom-mendation 25-30% glycol).

Permit Approval or a permit by the localmunicipality or district as well as ahydro-geological expert statement or assessment is required for each utili-zation of the surface water or ground-Water.Connecting an electric heat pumprequires a permit of the responsibleelectric company or utility.

Heat Source Connection LinesTapping lines must be kept as shortas possible. Lines and fittings must be

resistant to groundwater.Condensation forms on lines andfittings in warm rooms. This must beprevented with vapor proof insulationmaterial or collected with a drip tray.The installation must be protected fromcorrosion.To prevent evaporator malfunctions,a flow controller and a frost protectionmust be installed regardless of theapplication case. If an intermediatecircuit is used, the material compatibilityof the lines with the antifreezeagents must be checked (no

galvanized lines).

Heat Source IntakeThe same volume of extracted ground-water must be returned in the directionof the flow (distance > 15 m).The specified min, return temperaturemay not drop below + 4ºC. The size of the well is dimensioned for a specificrate of delivery.Pay attention to local authoritiesregulations.

Only professionally dug wells ensureproper, trouble-free operation.

Heat is usually extracted from surfacewater in three ways:

• Collectors in flowing water

• Filter well for the indirect use of surface waters

• Filter well for the indirect use of surface waters groundwater intake

The advantage of the filter wellsolution is that the extracted water isvirtually free of dirt and particles.

The groundwater intake has to becarried out in sufficient depth(below the thermocline).

A geological expert opinion must beobtained to determine the groundwater capacity.

Calculation of groundwater pumpThe geodesic height (h) is to be addedto the pressure loss to calculate thegroundwater pump since this is anopen system. Please note that thevalue of the geodesic height has adirect relationship with the resultingassociated power input of the wellpump, which is why this parameter must be taken into account whencalculating the efficiency factor of theoverall system.

Cooling with Heat Pump Systems

Definition:

Free Cooling A comfortable room climate regardlessof the season is becoming increasinglyimportant, especially in newly con-structed housing units. This can beachieved or improved with free coolingwhich transfers excess room heat to aheat exchanger and from there directlyto the geothermal probe or the ground-water.The cooling circuit of the heatexchanger is not running for this typeof cooling, hence the term "free cooling."

Cooling is achieved solely with the heatexchanger between heat source anddistributor system, thanks to an addi-tionally installed heat exchanger.The source pump and the cooling circuitpump (=heat circuit pump) are both inoperation. The following points must beobserved or are worth noting:- This type of cooling is cost-efficient

since only the electricity for thecirculating pumps is needed for thesystem to work.(Note: With groundwater, therequired drive energy increases

with the depth of the well.)- However, this cooling capacity hasits limits since the source is unableto absorb and emit energy continu-ously. If the entire coolingdemand cannot be covered rightaway, the achieved cooling effectin conjunction with sufficientshading of the rooms and withclosed windows noticeably lowersthe room temperature.Furthermore the cooling capacity isreduced in summer by warming of the soil around the probes.This system is therefore suitablefor the field of domestic buildingsindustrial cooling.

- Distributor systems: Floor heatershave limited usability (additionalcooling output limits), coolingceilings are optimal, radiators arenot permitted.

- Thermostat valves must be openin summer.

- Rooms with increased heatingdemand in winter (bathrooms, etc.)are somewhat more heavily cooledin summer due to the corre-spondingly dimensioned heatexchanger surface, something thatmay not be desired.This undesired effect can beavoided if Measures are takenon-site to ensure that thethermostat valves for these roomsremains closed in the summer.

The heat input into the geothermal probein the summer also has the positive side

effect of a certain probe regeneration,which slightly raises the probe outputtemperature, which in turn leads to aslight increase of the coefficient,especially of the water heating in thesummer.

Cooling Capacity and Energy of theSoilIn addition to the temperature differencebetween soil and room temperature,the available or utilizable extractioncapacity and cooling energy must beconsidered for the cooling process.

A dimension of Ø 32 mm is listed for pipes as a reference value; however,the values of the offices for geologicalassessments are to be complied within reality.

Active Cool ing A defined cooling output, however, isreached through active cooling, usingthe reversible heat pumps AQUATOPTR in combination with a distributor system suitable for heating and cooling(e.g. fan coil). Contrary to free cooling,active cooling runs the compressor of the heat pump (reversing the coolingcircuit). This involves a process reversalwhile in cooling mode. In this case,the heat output side (condenser)becomes the heat absorption side(evaporator).During this phase, the heat pumpfunctions as a refrigerator.

The cooling and heating cycle cannotrun at the same time. The use of a coolstorage is recommended to prevent toomany switching commands being sentto the heat pump (on, off, switching towater heating). Depending on thesystem concept, the heating storagecan also be used as cooling storage.

Act ive cool ing advantages:- his type of cooling has the advan-

tage that the cold output can beensured for the entire cooling period,which means room temperatures or the temperature of the fluid to be

cooled remains constant at all times.- Operating temperatures below the

dew point are possible as well, whichallows for the use of a fan mono-block or fan coils to dehumidify theair, which is especially desirable incommercial systems.

Act ive Cooling InsulationWater at a temperature less than 17°Cis considered to be cold water. In thepresence of cold water, the usual heatingsystem insulations cannot be used.Suitable insulation, especially when

using active cooling, is necessary.Insulation suitable for cold water isprimarily used to avoid condensationbut also to prevent cold water absorbingany of the heat, and also to protectagainst external mechanical stresses.Condensation must be avoided witha suitable insulation to prevent surfacecorrosions on the distributor system or mold in moist layers.Insulation for cold water must be vapor-proof and installed to all distributor system elements (pipes, ducts, tanks,pumps, cocks, valves, etc.) in a vapor-proof manner.Special insulating materials arecommercially available in differentdesigns (e.g. Armaflex, Tubolit).Standards SIA 380, DIN 4140 describethe insulation techniques.Please comply with the guidelines of relevant local professional associations(VSI, VDI, FESI).

Planning Notes


Measures to Reduce the BuildingCooling CapacityThe room cooling capacity is calculatedbased on the sum of the individualroom demand. If the cooling demandexceeds the available cooling capacity,the following reduction measures maybe used:1. Direct sunlight through the window

areas can be restricted throughconstructional measures (shutters,window shades, blinds).

2. The amount of sunlight receivedby each room frequently differsdue to the different cardinal points.

This means that not the entirecooling capacity must be availableat the same time. This can reducethe max. simultaneous coolingdemand.

3. Nighttime cooling of constructionalelements can also lower thedaytime cooling demand.

4. With systems that have very highcooling peaks during the day(exhibits, shopping centers, etc.),the peak load can be lowered bycooling the core by cooling downthe heavy construction components

(concrete walls and ceilings)during the normal downtime of thesystem, e.g. at night.

AQUATOP TR Source PumpReversible heat pumps require theuse of speed-controlled source pumpsto control the condenser condensationrequired for the correct cooling opera-tion of reversible heat pumps.These are controlled by the heatpump controller using a 0-10 V or aPWM signal (pulse modulation).

Factors

Private residences 20-40 W/m2

Offices 40-70 W/m2

Sales rooms 50-100 W/m2

Glass additions 150-200 W/m2

Calculating the Cooling CapacityThe cooling demand is calculated inaccordance with national and localstandards such as VDI 2078:Real estate and buildings

DIN 18599:Energetic assessmentof nonresidential buildings (alsoincludes air-conditioning or cooling)

DIN EN ISO 13790:Energetic assessment of buildings(similar to DIN 18599) only across

Europe DIN EN 255SIA382/2: Room temperaturerequirements.

SIA382/3:Determining the cooling requirementof building.

Cooling is differentiated by internalcooling capacity (e.g. thermal dischargeof equipment, persons, lights) andexternal cooling capacity (sun exposure,heat from building components, andventilation gains due to exterior air).

The estimate acc. to HEA can be usedfor approximate calculations. However,the conditions listed below must betaken into account as well.The calculations of the implementationphase must be based on national andlocal standards.

Empirical data for a quick calculation:

Basic Cooling Information1. The cooling cycle always must be

monitored. If the room air is cooledunchecked, condensation water willemerge.This may damage the equipmentor building components. The flowtemperature in conjunction with thehumidity (dew point contacttemperature detector or roomsensor for humidity and tempera-ture) is best for monitoring.

2. A separate cooling circuit shouldbe planned for the cooling mode.This circuit can be combined with

a cooling ceiling or ventilationsystem, for example.Partial cooling via the floor heater or convectors is also possible if theneed for cooling is limited.

3. Water flow must be ensured or cooling is not possible. Whencooling via the heating surfaces,thermostatic individual controlsmust be used that can be switchedto cooling mode.

Planning Notes


Comfortable Room Temperature

A room is considered to be thermallycomfortable when the room tempera-ture in the summer is below 28°C.This does not apply to air-conditionedrooms. Other factors are affectingthermal comfort ranges as well.Thermal comfort requirements aredefined in standard DIN EN 15251,which provides a general guidelinewhen implementing constructionprojects.

A comfortable room temperaturedepends significantly on the outside

temperature. When cooling, insidetemperatures should not be more thanapprox. 3-6°C below the outsidetemperature to prevent cold shock.The comfort range is depicted in thegraphic.

Recommendations for SurfaceTemperatures of Cooled FloorsWhen using a floor area for cooling,the comfort requirements and theweather data can be used to estimatethe condensation risk so that the

surface temperatures should generallybe in a range of 20°C to 29°C.Special attention must be paid to floor surfaces that are used when barefoot,for example, in bathrooms, since thesurface temperatures perceives asbeing comfortable may be significantlyhigher depending on the floor covering.Rooms with high humidity loads,especially bathrooms and kitchens,should not be cooled or only byconsidering the dew point threshold.

Monitoring Function to PreventCondensate Precipitation

To avoid condensation, the integratedLOGON B WP controller featuresdifferent monitor functions.

1. Flow Temperature MonitoringThe temperature is set at the factory to18°C. This temperature value ensuresin almost all cases that condensationdoes not occur. A dew point monitor should always be used in addition.

2. Dew Point Moni tor This device is attached to critical pointssuch as the floor heating distributionbox. As soon as the connected dewpoint monitor detects condensation, itcloses the contact and thereby switchescooling off.

3. Hygros tatTo prevent condensate due to a toohigh room humidity, a hygrostat can beconnected, which then realizes a fixedflow temperature increase. As soon asthe value set at the hygrostat is

exceeded, the hygrostat closes thecontact and this triggers the flowtemperature set point increase set here.

Distributor box floo r heating

High-end Solutions:

4. HumidistatTo prevent condensate due to a toohigh room humidity, a humidistat canbe connected, which then realizes acontinuous flow set point increase.If the relative room humidity exceedsan adjustable value, the flow set pointis increased steadily.

5. Room Sensor for Humidity andTemperatureThe dew point temperature is deter-mined based on the relative roomhumidity and the associated room air temperature. To prevent water condensation on surfaces, the flowtemperature is min. limited by an ad-

justable value that is above the dewpoint temperature.

Dehumidifier An external dehumidification can beused in combination with the last twomonitoring functions (item 4 and 5).

An external dehumidifier can beswitched on to reduce rising humidityin the air.

AQUATOP T Cascade with PWH Isolating Circuit

93

Cascade:Thanks to the new heat pump controller LOGON WP61, it is possible to operateseveral heat generators of a system ina cascade arrangement. Cascades withup to max. 6 heat pumps, equipped withthe LOGON B WP61 controller, arefeasible without problems.When usinga cascade formation, the heat genera-tors switch on or off depending on thecurrent energy demand: If the currentlyrunning heat pump cannot satisfy theenergy demand within a specific time,an additional heat pump/heat generator switches on.

Appl ication / Descr ip tion:Several heat pumps, uncoupled withbuffer storage and mixed heating circuit.One heat pump specifically for heatingpotable water (AUQATOP T VersionHigh Temperature) is recommended.Water heating using the water heater with external exchanger (Magro charge).Optimal with floor or radiator heatingwith variable flow to optimize run timesand higher service water requirements.

Function Description:Heating CycleThe first heat pump is activated withsensor B4 and exterior sensor B9 whenheating is required. The storage chargepump Q9 is activated simultaneously.If the currently running heat pumpcannot satisfy the energy demandwithin a specific time, an additionalheat pump/heat generator switcheson (additional activation controlled bysensor B10 and assigned set point).Charging continues until the set point atthe lower sensor B41 has been reached.The heating circuit mixing valve Y1 is

controlled based on the flow sensor B1.

Hot Water Sensor B3 activates the water heating.Both charge pumps Q3 and Q33 areactivated. The thermal mixing valveensures that the charge is not releasedto the storage tank until the min. chargetemperature has been reached.Charging continues until the set pointat sensor B31 has been reached.Protection from Legionella pneumophilabacteria and auxiliary heating to ahigher temperature levels is carried out

via electrical heater element K6.Thanks to the PWH isolating circuit, aHP can be dimensioned and selectedspecifically for producing potable water.

For example, a standard model AQUATOP T can be combined with ahigh temperature AQUATOP THT.This makes it possible to heat potablewater more efficiently and allows to runthe system more efficiently as well sincethe heat pump is only specificallyassigned to heat potable water in thesummer. While in heating mode, theoutputs of the two heat pumps are addedto cover the required energy demand.

Heating CycleThe heat pump is activated via sensor B4 and exterior sensor B9 whenrequesting heat. The storage chargepump Q9 starts running simultaneously.Valves K28 remain in position AB-B.Storage is charged. Charging continuesuntil the set point has been reached atlower sensor B41. The heating circuitmixing valve Y1 is controlled via theflow sensor B1.

Cooling Cycle

The heat pump is activated via sensor B4 and exterior sensor B9 whenrequesting cooling. The four-way valveY22 of the heat pump is also actuated,which results in a process reversal of theheat pump: The heat out side(condenser) becomes the heat absorp-tion side (evaporator), i.e. theheating system is now cooled and thesource is heated. Valves K28 areactivated simultaneously (position AB-A)and the buffer storage is reversed or discharged. The reversal of the buffer storage ensures an optimal separation

in the buffer even while cooling. Thestorage charge pump Q9 starts runningsimultaneously. Storage is charged.Charging continues until the set point inthe buffer has been reached.The cooling circuit mixing valve Y1 iscontrolled via the flow sensor B1.


Important:- When used in applications with

active cooling, a vapor-diffusioncold insulation is mandatory for all system components (line,pumps, cocks, storage tanks, etc.)!

- In case of floor heaters, only apartial cooling is possible withflow temperatures above 18°C!

A condensate monitoring systemmust be provided!

- Use only in combination with adistribution system suitable for heating and cooling (e.g. fan coil).

- Process reversal valves K28 are

recommended with active coolingusing a system temperature of 7/12°C and large buffer storagevolumes.In case of partial cooling applications(system temperature > 18°C, floor heating) can be omitted.The source pump Q8 must bespeed-controlled for all reversible

AQUATOP TR models!
