HEAT PUMPS - CREATING A MORE COMFORTABLE & SUSTAINALE BUILDING ENVIRONMENT

By installing a Withair® heat pump, you can reduce your energy consumption costs by up to 86% compared to direct electricity. Here we are using the nature's free and renewable energy sources, such as: outdoor air, geothernal energy, solar energy, that minimises your CO2 emissions and pollution free. You can also enjoy an environmentally friendly, renewable and free energy source. The high level of efficiency means that an investment in a heat pump pays for itself quickly and gives you a secure supply of heat, cool and hot water, suitable for different climate all over the world.

Withair® the W01R series heat pumps involve a range of 282 models, with heating and cooling capacity among 2.6kW and 3,200kW, which allow to create "customized" solution, matching the different installations requests.


-- 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 90ºC.
* Low temperature ambient condition heating: ultra-low temperature ambient condition (-30ºC) to make hot water.
* Wide range of application : working well at temperature -35ºC~43ºC.
* 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.
* Applicable industries:
    90ºC hot water: Electroplating industry and slaughter industry, chemical industry, textile industry;
    70ºC hot water: Waste heat recovery, thermostatic cultivation, residential villas, nursing homes;
    40~70ºC hot water: Tobacco drying, greenhouse heating, animal breeding, agricultural drying;
    50ºC hot water: Hotels, sauna salon, health care, household,etc;
