Low Noise Residential Heat Pump System / Air Source Heat Pump Air Conditioning
What is Residential Heat Pump System
Residential Heat Pump System (ASHP) is a system which transfers heat from outside to inside a building, or vice versa. 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

Knowlege of Air Source Heat Pump
When properly installed, anair-source heat pump can deliver one-and-a-half tothree times more heat energy to a home than theelectrical energy it consumes. This is possible becausea heat pump moves heat rather than converting it from fuel like combustion heating systems do.
