High Efficient Heat Pump Features

High Efficient Heat Pump

Air source heat pumps are designed for domestic/commercial space heating & cooling in the air conditioner market where lowest air temperature is above -10℃.

 ● Efficient and Energy-saving 

Air to water heat pumps absorb hot energy from the air freely, while the electricity is only used to drive the compressor to pump up the heat from the air, so they consume just a quarter of power of traditional heating systems, saving a lot of electric cost for users.  

 ● Green and Environmental Protection

By using air source energy and electric power,there is no harmful gas being discharged during the operattion of heat pumps. R410A refrigerant guarantees fluoride-free emission. 

 ● All-weather Operation

Stable operation without being influenced by windy, rainy or snowy weather. 

 ● Endurable 

Copeland scroll compressor, Danfoss electronic expansion valve, Eaton AC contactor and thermal relay as well as other brand components of the heat pump guarantee high product quality and a long lifespan. All of our screws and clips  (both external and internal) are stainless steel. The cabinet we are using is made of  GALVANIZED STEEL, making the product more rust resistant and durable.

 ● Multiple Controller and Protection

High pressure, low pressur, overheating, overload anti-freezing, phase sequence, discharge temperature, suction temperature and so on. Controlled by multiple controllers or by computer (optional). 

 ● Linkage Function

 External signal on/off function

 ● Guaranteed Safety

Complete isolation of water and electricity avoids electric shock, explosion and poisoning. 

 ● Convenient: 

Air to water heat pumps are easy to install. They can be placed in many places, such as garages, balconies, kitchens, etc.
