What Is The Air Source Heat Pump

An air source heat pump (ASHP) is a system which transfers heat from The surrounding environment air to hot water(or other medium).

Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called “reverse-cycle air conditioners”.

In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating and/or domestic hot water supply. The same system can often do the reverse in summer, cooling the inside of the house. When correctly specified, an ASHP can offer a full central heating solution and domestic hot water up to 70 °C.


Two Kinds Of Air Source Heat Pump:   Domestic & Commercial

Domestic Heat Pump Commercial Heat Pump
Water yield Compact structure, small volume, small heating capacity, less electric power input,
simple pipeline, easy to install
Large heating capacity, so Commercial Heat Pump are relatively bulky
Large electric power input needed
keep long time running .
manufacturer reserved a lot of space, in order to facilitate the air circulation and heat dissipation
Hot water tank Commonly Domestic heat pump use pressure tank  ,
no need hot water circulation pump
Normally Domestic Heat Pump need Free-surface Water Tank and Hot water circulation Pump
Flexibility With small power input, Domestic heat pump turn on/off easily. The commercial machine usually running for a long time or in stages
Heating method Fluorine circulation, that is to say, the water in the tank is stationary, Heat transfer in the water tank after the fluorine is heated through the Heat Pump, Water circulation,  water flows from water tank to the Heat Pump, absorb heat there,then com back to water tank
