ALR HA - Air cooled water chillers

302 B - 98/04 A - page 2/28

The newly redesigned McQuay ALR HA (high ambient tem-perature) air cooled water chillers offer you unsurpassedefficiency, flexibility, reliability, and serviceability in a totalpackage concept. Improved to include the latest heattransfer surface design and the most advanced and efficientreciprocating compressors in the industry, the redesignedALR HA chillers exceed efficiency requirements. TheMcQuay air cooled water chillers are completely factoryassembled, piped, wired and shipped in one piece, readyfor installation. Each unit consists of compressors, insulatedevaporator, condenser coils with independent subcoolercircuits, multiple propeller type direct drive condenser fanswith independent fan motors, heavy-gauge weatherproofcasing and weatherproof electrical control centre containingall necessary and operating controls and motor startingequipment.

Highly flexible designThe ALR HA units is available in 26 sizes covering a rangefrom 404 to 1410 kW nominal cooling capacity with coolanttemperature between +10°C and -8°C. Many optional fea-tures can be added to fit all installation requirements.

Low installation costsThe complete assembly of the units and function testing atthe factory reduces the cost of installation on site. A rigidsteel base distributes the weight of the unit to the supportpoints and allows simple installation by an easy access tothe lifting points. The units are designed with a single pointthree-phase mains connection. All units are suppliedcomplete with refrigerants HCFC 22, HFC 407C or HFC134a.

Low maintenance costsThe microprocessor safety and control system allows thetrouble shooting of any type of functional anomaly,enabling simpler, safer and timely intervention by the unitmaintenance personnel. The oil heater in the sump on eachcompressor and a complete set of controls and safetydevices protect the unit from abnormal operating conditions.

Code requirements All units are designed and manufactured in accordance withapplicable selections of the following which are equivalentto American Air-conditioning industry applicable codes:Rating of chillers: UNI 9018Construction of pressure vessel: TÜV Standards (optional)Electrical codes: IEC 204-1 CEI 44-5 Elect. & Safety CodesSafety Codes: CEI-EN 60204-1 CodesManufacturing Quality Stds: ISO 9001

Factory testingEach unit is pressure tested, evacuated and charged withthe refrigerant requested. It is then tested at the factory’stest bench under the design conditions specified by thecustomer. Upon request, a second series of tests can becarried out witnessed by the customer (see option 92).Before shipment, each unit is re-checked for pressure andrefrigerant charge control.

General characteristicsCabinet and structureThe cabinet is made of galvanized steel sheet and paintedto provide a high resistance to corrosion. The unit baseframe has holes to lift the unit with ropes for an easy instal-lation. The weight is uniformly distributed along the profiles

of the base and this facilitates the arrangement of the unit’sbases and the support structures. The electrical and controlequipment is located inside cubicles which can be accessedby key locked doors complete with door interlocking on thepower cabinet.

Semi-hermetic compressorsCompressors are reciprocating type 4, 6 or 8 cylinders withsuction and discharge valves of the disc type. The forced lu-brication is obtained through a reversible gear type pump.The oil heater is automatically switched on when the com-pressor stops to prevent oil dilution from liquid refrigerantand in order to keep the right fluidity. The electrical motorsare protected against thermal over load through thermistorsembedded in each of the three phases of the statoricwindings. The ALR HA units, are equipped with McQuay800 and 900 S compressors.

EvaporatorThe evaporator is a direct expansion shell-and-tube typewith water flowing in the baffled shell side and refrigerantflowing through the tubes. The ALR HA evaporator are de-signed in more separate refrigerant circuits, one for eachcompressor. The evaporator is manufactured with a carbonsteel shell and seamless high efficiency copper tubes. Rollexpansion anchors the refrigerant tubes in the heavy car-bon steel tube sheet. Water baffles are polypropylene to re-sist corrosion. Refrigerant head is in carbon steel and is re-movable to permit access to the tubes. The evaporator iswrapped with closed-cell heat insulation.

Condenser coilsThe new ALR HA units are constructed with internally en-hanced seamless copper tubes arranged in a staggered rowpattern and mechanically expanded into McQuay lancedand rippled aluminium condenser fins with full fin collars.An integral subcooling circuit provided sufficient sub coolingto effectively eliminate liquid flashing and increases in cool-ing capacity up to 8% without increasing in absorbedpower.

Condenser coil fans The condenser fans are of the helical type with wing-profileblades to achieve a better performance. The direct couplingwith the electrical motor eliminates any problems as regardsthe application of transmission devices and reduces the vi-brations caused by the functioning. The motors are suppliedas standard totally enclosed (Insulation class F) and are ofthe three-phase type; they are protected againstoverloading and short circuits by circuit breakers located in-side the electrical control panel. The fans operate informed bell shaped orifices.

Electrical control panel The components of both the power and the control are splitinto two sections of one main panel, accessed by individualkey locked doors to prevent unauthorised entry. The panelis manufactured to insure protection in all weather condi-tions and the doors are fitted with door-stays to prevent ac-cidental closure. The power panel is fitted with a door inter-locked mains isolator to prevent access while it is live.Power section includes: This section of the panel includescontactors, all the fuses for the compressors and thecondenser fans, control circuit transformer. Additional spaceis provided for the installation of the various optional acces-sories provided to enhance the capabilities of the ALR HAunits.

Control section includes: Microprocessor is installed as

302 B - 98/04 A - page 3/28

standard on all the units. Its touch sensitive keypad consistsof keys that can be used to alter unit set points and controlcommands. A display on two lines illustrates the machine'soperating status & programable parameters (setpoints) e.g.temperatures & pressures of fluids (water, refrigerant)controller maximise the McQuay chillers energy efficiencyand reliability characteristics. It uses sophisticated softwarewith predictive logic to select the most energy efficient com-bination of compressor, condenser fan to maintain stableoperating conditions and maximise energy efficiency. Thecompressors are automatically rotated to ensure equal ope-rating hours. Controller intervenes to protect critical compo-nents in response to external signals from its system sen-sors measuring: motor temperatures, refrigerant gas and oilpressures, electrical supply and evaporator.

Refrigerant circuitThe ALR HA units are equipped with a complete refrigerantcircuit charge HCFC22, HFC407C or HFC134a. The circuitconsists of insulated copper pipes on the suction line and iscomplete with filter driers, moisture indicators, liquid sightglass, thermostatic expansion valves.

Selection Procedures The procedure for selecting the cooling duty and the powerabsorbed by the compressors of the ALR HA units isindicated below.

1. The tables “Standard ALR HA unit performance” allow todetermine the cooling capacity, power absorbed by thecompressor motors with cooled water temperatures bet-ween +4°C and +9°C, ambient air temperatures between +25°C and +52°C.

2. Although the data can be interpolated, extrapolation is notpermitted. For conditions other than those shown in thetables, contact McQuay Product Group.

3. The performance of the ALR HA units refers to 5°C of ∆tof chilled water. The increase or reduction of the flow rate ofchilled water produces a reduction and an increase in thecooling performance which is negligible. To ensure thecorrect functioning of the exchanger, it is advisable tomaintain the water’s ∆t within 3°C ÷ 6°C.

4. The performance figures are based on Fouling factor of0.044 m2°C/kW. In the event of different values, thecorrection coefficients indicated in Table 2 should be used.

5. The performance is influenced by air density. Table 3gives the correction factors for the various altitudes abovesea level.

6. The power absorbed values given in the standardperformance tables refer to the compressors only. The

302 B - 98/04 A - page 4/28

current absorbed by the fans is given in the electricalcharacteristics table.

8. To obtain the flow resistance through the evaporator, usethe diagrams on page 9.

Example of selection of an ALR HA unitData:

Cooling capacity required: 650 kW

Ambient air temperature: +46°C

Temperature of cooled water: from 12 to 7°C

Refrigerant: HCFC22

Fouling factor: 0.132 m2°C/kW

Altitude above sea level: 900 m

Glycol content: none

1. The cooling capacity correction coefficient for fouling 0.132 m2°C/kW (Table 2) is 0.975.

2. The cooling capacity correction coefficient for installationat 900 m above sea level (Table 3) is 0.979.

3. The corrected cooling capacity is 650 kW/0.975/0.979 = 681 kW.

4. The cooling unit to satisfy this capacity is ALR HA 230.2ST 022. This unit will have the following operating data:

Cooling capacity: 684 kW x 0.975 x 0.979 = 652,9 kW

Power absorbed by compressors: 243,1 kW x 0.986 x 1.015 = 243,3 kW.

Chilled water flow rate: 652,9 kW/4.186/(12-7) = 31,2 l/s.

Pressure drop indicated by the diagram on page 9 with acooled water flow of 31,2 l/s on the straight linecorresponding to the unit ALR HA 230.2 we find a pressuredrop of 32 kPa.

Water content in cooling circuitsThe cooled water distribution circuits should have aminimum water content to avoid excessive intermittentoperation of the compressors. In fact, each time thecompressor starts up, an excessive quantity of oil goes fromthe compressor’s sump and simultaneously there is a rise in

the temperature of the compressor motor’s stator due to theinrush current during the start-up. To prevent damage to thecompressors, McQuay has envisaged the application of adevice to limit frequent stops and restarts.

During the span of one hour there will be no more than 6starts of the compressor. The plant side should thereforeensure that the overall water content allows a more constantfunctioning of the unit and consequently greaterenvironmental comfort. The minimum installation water con-tent envisaged should be calculated with a certainapproximation using this formula:

(1) Q = P x p 25

where:

Q = minimum content of the plant expressed in litres.

P = cooling capacity of the plant expressed in W

p = minimum unloading capacity percentage

A plant with a 445 kW cooling capacity in which the coolingunit ALR 120.2 ST 022 equipped with two compressors isapplied, should have a minimum content of water calculatedon the basis of the minimum cooling capacity, which for thistype of equipment is 25% of the nominal capacity.

Q = 445000 x 0.25 = 4450 l 25

For a more accurate determination of the quantity of water,it is advisable to contact the designer of the plant.When thesum of the water content of the evaporator, the pipes of thehydraulic circuit and the terminals (coils, exchangers, etc.) islower than the value obtained, it would be better to opt for aALR McQuay cooling unit equipped with inertial tank(optional).

Installation notes

HandlingAll moving and handling may damage the unit if someconditions are not scrupulously observed. The units shouldbe lifted with a crane using long ropes anchored to theholes on the frame of the unit’s base and by using the upperspacer bars (see accessory 80) to prevent the ropes fromdamaging the condenser coils.

Location The ALR units are produced for outside installation onroofs, floors or below ground level on condition that the areais free from obstacles for the passage of the condensationair. The unit should be positioned on solid foundations andperfectly level; in the case of installation on roofs or floors, itmay be advisable to arrange the use of suitable weightdistribution beams. When the units are installed on theground, a concrete base at least 250 mm wider and longerthan the unit’s footprint should be laid. Furthermore, thisbase should be sufficiently robust to withstand the unitweight mentioned in the technical data table. When theunits are positioned in areas which are easily accessible bypersons or animals, it is advisable to fit guards to protectthe condenser coil guards (see accessory 32) and, whennecessary, also guards to protect the compressor (seeaccessory 33).

Space requirementsThe ALR HA units are air-cooled, hence it is important toobserve the minimum distances which guarantee the bestventilation of the condenser coils. Limitations of space re-

ducing the air flow could cause significant reductions incooling capacity, an increase in electricity consumption and,in some cases, the unit may stop functioning as a result ofthe high condensation pressure. The fans do not allow theuse of ducts which have high flow resistance, hence isshould be ensured that the output air cannot recycle itselfinside the condenser coils. The units should be positionedsuch that there is sufficient distance between the coils andany obstacles to improve ventilation and also to facilitate in-spection. When two or more units are positioned side byside it is recommended that the condenser coils are at least3000 mm distance from one another. Smaller distancescould cause the recirculation of hot air. If the units arepositioned in places surrounded by walls or obstacles of thesame height as the units, the units should be at least 3000mm from said obstacles. For other installation solutions,consult McQuay technicians.

Acoustic protectionThe low noise levels of the ALR units means that they meetmost of the most restrictive regulations, thanks to theavailability of two versions with different sound levels: thestandard version (ST), the version with sound proofing cabi-net on compressors (CN). When the noise level must meetspecial requirements it will be necessary to pay themaximum attention to ensure the perfect insulation of theunit from the support base by applying appropriate vibration-dampening devices (see accessories 84 and 85), applyingvibration-dampening mounts on the water pipes and on theelectrical connections.

To supply and install, where specified in the project n° ..... unit(s)aircooled water chiller with cooling capacity of ..... kW, to cool .....m3/sec. of water from ..... °C to ..... working with ..... °C ambienttemperature. The unit should work with electricity at ..... V. 3ph.50Hz. The electrical power absorbed should not overcome ..... kW.The units COP will be at least ..... at the working conditions of theproject. Part load COP will be at least ..... at the working conditionsof the project. For the units with 2, 3 and 4 compressors the chil-lers wll have (2), (3) or (4) indipendent refrigerant circuits, with therespective electronic microprocessor will alow the starting of thecompressors. Each chiller will be factory assembled on a robustbaseframe made of zinc coated steel, with zinc coated panels, pro-tected by an epoxy coated paint. The painting of the chillers to con-form to the 500 hours salt spray test method 6061 (no. 141 STD)The unit will be tested at full load in the factory at the nominal wor-king conditions and water temperatures. Before shipment a full testwill be held to avoid any losses, and the units will be filled with oiland 134a refrigerant. Units will have the following components:

General - All units are designed and manufactured in accordan-ce with applicable selections of the following which are equivalentto American Air-conditioning industry applicable codes:Rating of chillers: UNI 9018Construction of pressure vessel: TÜV Standards (optional)Electrical codes: IEC 204-1 CEI 44-5 Elect. & Safety CodesSafety Codes: CEI-EN 60204-1 CodesManufacturing Quality Stds: ISO 9001Compressors - will incorporate ..... compressor(s) McQuay's alter-native semihermetic compressor(s) with many cylinders and platevalves, a crankcase heater, a protection spring for the valvesagainst liquid carryover, interchangeable cylinder jackets, overdi-mensioned oil filter with a fine mesh, on the suction line, with anadditional oil filter on the oil discharge and sight glass. The com-pressor will be supplied with a forced lubrication system with a re-versible pump and will be fully charged. Solenoid valves will beprovided to activate the cylinder by-pass between suction and dis-charge of the cylinder heads. Part winding / single speed compres-sor will be 1450 RPM or less.Compressor motor - the motors of the compressors cooled by thesuction gas and will be available in two versions: part winding anddouble speed. The part winding motor will have the windings divi-ded into two sections in order to reduce the inrush current which al-lows the reduced dimension of power supply. The double speedmotor will be built with two stator windings (4 and 8 poles) and willallow a better efficiency at low speed with better energy saving.Both motors will be thermally protected from high temperatures bysensors that are inserted in each of the phases of the windings.Evaporator - the units will be supplied with (1) or (2) direct expan-sion evaporators with refrigerant inside the tubes and water outsi-de, (shell side) with carbon steel tube sheets, with straight coppertubes that are spirally wound internally for higher efficiencies, ex-panded on the tube plates. Each evaporator will have two refrige-rant circuits (units with 2 or 4 compressors) or 3 refrigerant circuits(units with 3 compressors) one for each compressor. Testing andoperation pressure, refrig. side working pressure 15 Bar and waterside 10 Bar.Condenser coil - the condenser coils are constructed with inter-nally enchanced seamless copper tubes having a "W" configurationand arranged in a staggered row pattern and mechanically expan-ded into lanced and rippled aluminium fins with full fin collars for hi-gher efficiencies. The spacing between the fins are given by a col-lar that will increase the surface area in connection with the tubes,protecting them from ambient corrosion. The coils will have an inte-gral sybcooler circuit which provides sufficient subcooling to effecti-vely eliminate the possibility of liquid flashing and increase the

units efficiency up to 8% without an increase in power absorbed,and the surface area will be dimensioned in a way to permit an airvelocity not greater than 2,5 m/sec. Leak tested at 10 Bar and pres-sure tested at 30 Bar.Condenser fans - the fans are used in conjunction with the con-denser coils, they are of the impeller type with aerofoil polypropyle-ne blades for higher efficiencies and lower noise. The air dischargeis vertical and each fan will be coupled to the electrical motor, withthe casing made in aluminium and supplied as standard totalyenclosed with 6 poles and capable to work to ambient temperaturesof -40°C to +55°C. Each fan will be controlled by the condensingpressure of the relevent cooling circuit. There is also an accidentprotection within the motors. Condenser motors with Class F mo-tors. Cast aluminium condenser fan blades will be supplied asoption.Thermostatic expansion valve - each refrigerant circuit will beequipped with all the necessary components in order to ensure theworkings and service (dehydration filter, liquid sight glass, shut offvalve, load connection and pressure switch etc). Thermostatic ex-pansion valve regulates the injection of refrigerant liquid intoevaporators. Injection is controlled by the refrigerant superheat.Control panel - field power connection, control interlock terminals,and unit control system shall be centrally located in a weatherproofcabinet accessible through a key locked door. Power and startingcontrols shall be separate from safety and operating controls in dif-ferent compartments of the same panel.Power and starting com-partment shall be protected by a plastic cover. Power and startingcontrols shall include fuses and contactors for each compressorwinding and fan motors. Operating and safety controls shall includeenergy saving control; emergency stop switch; solid-state protec-tion for compressor motor; differential oil pressure safety switch (foreach compressor); high and low pressure cut-out switch (for eachrefrigerant circuit); anti-freeze thermostat; compressor lead-lagswitch (on 2 compressor units only); cut-out switch for each com-pressor; operating hour meter (for each compressor).Regulation of cooling capacity - each unit will have a controllerfor the control and operation of the unit with 4, 6 or 8 steps of capa-city control depending on the number of compressors. All of the in-formation regarding the unit will be reported on the controller dis-play with 32 characters and with the internal built in calender andclock this will switch the unit ON/OFF during day time all year long.The microprocessor permits a "soft start" function throughout an ex-ternal signal will allow a load reduction of the unit when there arepeaks of absorbed current. In addition a connection to a BMSsystem can be made via an "open protocol" or an interface via amodem to a personnal computer. All general alarms can be memo-rised by an easy analysis of the faults and their causes.High and low temperature function - the units will be providedwith an automatic control for condensing pressure which ensuresthe working at low external temperatures down to +5°C, because ofthe working cycle of the condenser fans, in respect to the conden-sing pressure. The unit needs to be able to work with high externalambient temperatures up to 52°C and capable of starting at 46°C atfully loaded condition. Low temperature starting with fantrol (stan-dard) will be less than 0°C and with speedtrol (option) this will be -18 °CRefrigerant piping - refrigerant circuit shall include a factory insu-lated suction line, manual liquid line shut-off valve with chargingconnection; refrigerant filter drier with replaceable core; liquid sightglass/moisture indicator; liquid line solenoid valve; thermostatic ex-pansion valve, and 27 bar relief valve. Records for the refrigerantpressure manometer and oil will be placed inside the control cabi-net. Flexible refrigerant piping hot gas muffler, though not required,can also be offered as option.
