High Efficiency Cold Climate Air Source Heat Pump Home Heating And Cooling
Cold Climate Air Source Heat Pump Features
● Energy Efficient
Cold Climate Air Source Heat Pump absorb hot energy from the air freely, and the electricity is only used to drive the compressor to pump up the heat from the air. So, it consumes just a quarter of traditional electric heaters, saving a lot of electric costs for users.
● Environmental Protection
By using air hot energy and electric energy, there is no harmful gas being discharged during the operation of heat pumps. R407a refrigerant guarantees fluoride-free emission.
● All weather Operation
All weather operation: stable operation without being influenced by any windy, rainy or snowy weather.
● Endurable
The Enhanced Vapor Injection (EVI) technology from Copeland compressor with crankcase heater for special cold area, Danfoss electronic expansion valve, Eaton AC contactor and thermal relay and other brand components of the heat pump guarantee high quality and a long lifespan. All of our screws and clips (both external and internal) are stainless steel. The cabinets we are using are made of GALVANIZED STEEL, making them more rust resistant, durable and affordable.
● Multiple Controller and Protection
High pressure, low pressure, overheating, overload anti-freezing, phase sequence, discharge temperature, suction temperature and so on. Controlled by multiple controller 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; LCD screen digital controller for automatic operation
● Convenient
The heat pump is easy to install in many places, such as garage, balcony, kitchen, etc.
