What is an Air Source Heat Pump?

An air source heat pump provides efficient heating as well as cooling to your home, office or any building in need of such system. If installed in a proper way, an air source heat pump can deliver 1.5 to 3 times additional heat energy to a home than the consumed electrical energy.

Working Principle of Air Source Heat Pumps:

It works under the principle of vapor compression. An air source heat pump makes use of refrigerant system that involves a compressor and a condenser to absorb heat from one place and release it at another place exactly in the similar way as a refrigerator system does. Before plunging into the technology, it is necessary to know that air at a temperature above absolute zero always contains some heat and most of the heat pumps can extract heat at much lower temperatures i.e. about -15 degrees Celsius.

Technology Used:

The air source heat pump consists of two exchanger coils out of which one that outside catches the hot air and the other one that is inside pushed that air through a heating system. The system consists of four major elements i.e. a compressor, a condenser, an expansion valve and an evaporator that allow the refrigerant to pass from the liquid form to its gaseous form. When the refrigerant passes through the system, the high temperature which is more than 100 degrees Celsius, converts it into its vapor or gas form while the energy produces heat. Now the gas formed passes through the compressor that increases its temperature and then passes through the expansion valve which lets the hot air enter the building. Now, this hot air goes through the condenser that converts the gas again into its liquid form. The heat hence produced by the evaporation phase energy passes through the heat exchanger again to resume the cycle. It helps in making the radiators to work for the underfloor heating system as well as for domestic hot water system.
