—— Product Description ——

Withair® CO2 heat pump is a kind of carbon dioxide (R744) as refrigerant refrigeration unit, through the refrigeration cycle, from the nature of the medium, such as air, water and capture the low grade heat source, transfer and deliver to people production and living with the high quality of heat energy.Unlike the conventional heat pump, CO2 heat pump of 65-90 °C high temperature hot water can be produced, has the incomparable advantages such as energy saving, environmental protection.

Compressor suction from the evaporator of the low temperature low pressure gas CO2 refrigerant, carbon dioxide by doing work refrigerant compressed into high temperature and high pressure supercritical fluid, high temperature and high pressure supercritical fluid into the gas cooler and water exchange heat, cooling into a high pressure fluid in the gas cooler and release large amounts of heat, water absorption of the release quantity of heat and temperature rising.High pressure fluid after expansion valve throttling depressurization, through the role of the fan in the evaporator, absorbing heat and evaporate into low pressure gas in the ambient air, and inhaled compressor medium-pressure shrinkage, such repeated cycle, thus making hot water.

—— The Key Advantages Include ——

● Excellent high temperature heating performance : the highest outlet water temperature 90℃.

● Low temperature ambient condition heating: ultra-low temperature ambient condition (-30℃) to make hot water.

● Wide range of application :working well at temperature -30℃~43℃.

● Safety and environmental protection :zero Emission ODP(Ozone depletion potential), Non - pollution,Non-toxic non-flammable.

● The independent design and manufacturing of high efficiency heat exchanger, strong energy saving and anti-freeing.

● High efficiency: the COP can be up to 4. 5, and the COP still above 2.0 even in low temperature.

● Wide applicable scope: ambient -35°C to 43°C in normal work, suitable for most of the cold area for making life or industrial hot water.

● Electronic expansion valve throttle control, refrigerant flow control precision at at the cold temperature.

● Air side heat exchanger(hydrophilic aluminum fin) with anti-ice system design, prevent heat exchanger to frost at the cold temperature.

● Multi self-protection  functions, such as: high & low pressure, high temperature, water flow and antifreeze protection.

● Modular networking technology, the operation of individual modules can be coordinated according demand.

● Advanced & world-famous inverter compressor high-efficiency, low-noise and low-vibration operation.
