High Efficiency Air-cooled Heat Pump

Unit Classification

Operation Range

The latest CLIMAVENETA "ERACS.C-N" series high efficiency screw heat pump is totally imported from Italy and it's energy efficiency can fully reach Class A of European standard and Energy Saving Certificate of Chinese national code. For all units of air-cooled heat pump, the 4-way valve is equipped to reverse the circulation direction of refrigerant that can offer chilled water or hot water to users.

Because the unit is air source heat pump and using the reverse cycle, the cooling tower, cooled water pump and cooled water system can de deleted that the investment and operation charge of cooled system can be reduced. And the unit can be installed on the building roof or outside, no need extra room. So the ERACS.C-N units suit for all commercial and industry application and can fulfill the air-conditioning and heating request all year round.The unit adopts Intelligent defrost programme to ensure safe operation and stable heating in winter.The environment friendly refrigerant HFC134a is used for better running efficiency and the temperature tolerance in summer and hot water temperature in winter are both higher.

ERACS2222C-N-D-Bmeans high efficiency screw heat pump unit using R134a with partial heat recovery function and unit model is 2222.

Screw Type Compressor● Semi-hermetic screw compressor specially designed for HFC134a with higher compression efficiency under full load as well as part load; ● Precisely manufactured twin-screw rotor with aircraft-grade bear featuring in high reliability, low noise, low vibration and stable running;● The motor drive the bear directly with least moving component and wearing part that cause no energy loss and higher mechanical efficiency;● Automatically adjust power output according to load by microprocessor. The slide valve is fixed for stepless control and increase part load performance.

Energy Saving and Environment FriendlyAll units of ERACS.C-N series can reach Class A according to European energy efficiency standard and Chinese energy saving standard.

Heating in Super Low Temp.Super heat exchanger with injecting cooling and intelligent defrost technology to make sure heating even in -10℃. So the balance between reliability and COP of heating in super low temp. is perfectly achieved.

Innovative Intelligent Defrost Function (CLIMAVENETA Patent)The reverse cycle type intelligent defrost function introduce the self-adjust technology which can automatically modify and regulate the judgement and data for next defrosting according to the change of ambient air temperature, humidity and defrost time as well as the difficult level of last defrosting. So the defrost no longer need manual adjusting and it can be fit for all kinds of weather condition.

Much precise, reliable and energy saving from traditional defrosting method.

Unit FeaturesElectric Expansion Valve● EEV for precise control to meet load change.

Green Technology● Environment friendly HFC134a;● Optimize the refrigerant system to reduce energy consumption and CO2 emission.

High Performance FanHigh efficiency exterior rotor fan from German brand with variable speed controller. It can change fan speed automatically (DVV design) to reduce energy consumption and fan noise.

Super Low NoiseAll compressors of ERACS.C-N series are equipped inside the sound proof housing. And the compressor is installed on the spring isolator. The rubber pad is also fixed between compressor and frame to prevent vibration and noise. The fan is exclusive designed with aircraft grade blades and aluminum-cast exterior motor as well as the air deflector cylinder to eliminate air side noise.

According to different noise request in different application, the super low noise unit also can be installed.The noise of super low noise unit (SL) is 8-10 dB(A) lower than standard unit (B).

Build-in pump and hydraulic kitThe build-in water pump (available in different head) or hydraulic kit can be selected for the unit. The hydraulic kit includes all necessary kits such as strainer, pump, safety valve, pressure gauge, pressure difference switch, stop valve and pump control system.

Customer can simplify the installation on site, save installation area and increase auto-control level by selecting build-in kits.

Reliable OperationThe unit is designed, manufactured, tested according to international and local standard AHRI, EN, UNI, JIS, GB/T18430.1 for reliable performance. And the electrical system is also strictly designed and produced comply with standard IEC60204-1/GB5226.1. The unit is controlled by the dedicated microprocessor control system. In order to protect operation safety, the high/low pressure switch, over/under voltage, phase failure, phase reverse, over load, winding over heat, gas exhaust temperature, water flow switch and oil heater are all equipped.

For the evaporator, the heater is attached to the evaporator exterior to prevent freezing.

Heat Recovery-Hot water free!The heat of condensation usually will be exhaust to the environment during air-cooled heat pump working in cooling. And also the unit can not transfer all the heat during heating. So CLIMAVENETA introduce the heat recovery technology which can recovery the condensation heat during cooling and extra heat during heating to produce free hot water. This technology will help users to save obvious operation cost.

Optional Function● Available optional function: low temperature refrigeration, ice storage, fin protection, salt spray protection of fins, remote

keyboard, power factor regulation.

Dedicated EconomizerThe dedicated economizer is equipped for all units to increase heat exchange and supercooling. Finally enhance working performance and efficiency.

Latest Control SystemAll unit are equipped with latest control system, friendly human-computer interface for excellent control performance, better

extended function, regulation ability and compatibility.

Friendly Interface● New generation regulation system with human-

computer interface, better extended utility, supervision and

compatibility.

● Panel screen on the unit, easy operation, better

protection Microprocessor regulation fulfill human-free

running.

● W3000 with LCD display, multi-language & multilevel

menu for data display & set-point regulation .

According to CLIMAVENETA tradition, another display of

compressor’ working data is adopted for easy supervision.

Unit Control and Operation Regulation ● Dedicated W3000 microprocessor is inserted with CLIMAVENETA control algorithm to make sure energy saving and reliability.

● FIFO compressor running time balance function extends unit’ working life;

● Auto compressor power input control following with load change from 10-100% for energy saving;

Climaceneta User pipeline

Precautions:1. The air-exhaust valve should be fixed at the highest point of chilled water pipeline.

2. Unit evaporator import and export must be equipped with rubber flexible connection, as well as the chilled water pipe of water-

cooled units.

3. A flow switch should be installed on the horizontal pipeline of both cooling water side and chilled water side, and the flow switch

should connect to the control system of the unit.

4. A bypass with gate valves is recommended to enable the pipes to be washed through without having to disconnect the unit.

When the system water quality corresponds with the requirement after enough wash and cleaning, the unit could be connected

to the water circuit. But in order to prevent any damage, water MUST NOT enter the unit BEFORE our service engineer arriving

at the site.

5. Y-Strainer Must be installed in front of the evaporator inlet pipe (60 holes or more), to ensure that the evaporator circulating

water must not contain any impurities such as metal materials, welding slag, steel wire.

6. In order to ensure the unit heat exchanger not be corrosive due to water quality. The water shall not contain corrosive ions

such as chloride ions, ammonium ions, sulfur ions according to the chemical characteristics of the copper. If the unit is used

in the hard water areas, an extra qualified water softening devices should be installed on the water system to make sure the

bicarbonate content comply with national standards.

7. For outdoor installed units, the outdoor pipes should install draining valve. In winter when unit is not in use, it can drain all water

inside the unit, to avoid freezing pipes or unit.

8. Evaporator inlet and outlet pipe should be equipped with shut off valve.
