Units Description

CLIMAVENETA AQS air cooled chiller/heat pump can save the investment of cooling system and the operating cost, also the unit can be installed on the roof without extra plant room. The unit is wildly suitable to commercial and industrial application and meets both the cooling and heating requirements. The unit is widely used in hospitals, hotels, office buildings, shopping malls and other air-conditioning occasions, It can meet th e needs of air conditioning and heating throughout the year.




  • Intelligent UPC microprocessor with human-machine interface
    screen, unit managing, network and communication, protection
    when under alarm and alarm management functions.


  • Multi-language menu, shortcut key, graphic unit status. Average
    compressor running time to extend unit working life.

Different from the traditional heat pump, CLIMAVENETA developed the SMART DEFROST system. It has the self-adaptive function which can modify and adjust the next defrost process based on outdoor temperature and humidity as well as last defrost result.

  • Patented exhaust channel, reducing compressor noise


  • P a t e n t e d m o v i n g p a r t s , e n h a n c i n g compressor reliability


  • Using PVE lubricating oil to improve the lubrication performance and oil return performance of the compressor


  • Outer / inner shell design: the compressor motor is cooled by suction refrigerant and does not directly contact the lubricating oil, and the oil circulation rate is low.


  • Unique suction refrigerant flow design: lubricating oil mainly stored in the middle layer of inner and outer shell and the suction refrigerant will not stir the lubricating oil.


  • Unique scroll plate design, more reliable and with higher efficiency.

Use the high efficient components
including scroll compressor,plate
heat exchanger and HFC410A.The
performance coefficient of the unit can
arrive GB grade 2 efficiency(China
National Standard). We provide user
with quality products and save the
money for user at the same time .

  • Environment friendly HFC410A,no damage to the ozone layer (ODP=0)


  • Higher volumetric refrigerationcapacities, so better heat transfer ability and efficiency.


  • Less charge amount of the refrigerant which reduce the CO2 emission and greenhouse effect.

Adopt high quality AISI316 stainless steel plat heat exchanger. The close-cell thermal insulation material is attached on the exchanger to prevent condensation on the external surface. The electric heater inside the exchanger also can avoid frozen in extreme environment.

Features and Benefits

Efficient Condenser

The air-side heat exchanger adopts a U-shaped design to increase the effective area of heat exchange and has a remarkable heat transfer effect. High heat transfer efficiency vortex-shaped internal thread copper tube increases heat exchange area and refrigerant disturbance to improve heat transfer.


The intelligent microprocessor have perfect protection function, such as protection when fault, alarm, record and analysis. Besides, the high and low pressure switch, fault phase, anti-phase, over load, over current, over heat, discharge gas temperature, water flow, anti-frozen functions are also equipped. And the fault can be recorded and alarm can be displayed.

Working Under Extreme Environment

Thanks to the large area heat exchanger and SMART DEFROST, the unit can operate reliably under low outdoor temperature that perfectly solved the problem between operation reliability under low outdoor temp. and high efficiency.

Electric Expansion Valve

  • Precisely control the gas flow to optimize the evaporator’s performance;
  • Adjust the system based on the superheat degree of suction gas for reliable running;
  • Improve the efficiency when the unit operates deviate the nominal condition or under low load condition;
  • Changes rapidly according to the load, and the water temperature is stable.

Low Noise

The compressor and refrigeration system of the Climaveneta air-cooled unit are placed in the sound insulation board, and the rubber anti-vibration pad is used at the frame connection of the compressor to prevent vibration and noise transmission. The fan uses aerospace fan blades and aluminum cast outer rotor motors to reduce airflow noise.
