Heat and cooling almost occupy half of the energy bill in your family. That will be a big number. So it is time to find way to reduce this account. Air source heat pumps will help you a lot.
Air source heat pumps adopt the principle of Reverse Carnot which absorbs energy from the outside air to heat/cool the water for house heating, cooling and domestic hot water. Compressor, evaporators, condensers and throttle devices constitute the four major parts of air source heat pumps. The refrigerant as the media will make an important role of transporting heat.
In the cold winter, refrigerant will be pumped into high temperature and high pressure air by compressors. When crossing the heat exchanger, the refrigerant will release the heat for the water to heat the house or produce the hot water for daily use.
On the contrary, in the hot summer, the refrigerant will not through the compressors but the heat exchangers to absorb heat and cool down the temperature in the indoor room.
All of these procedures just use small amount of driven electronic, but the air source heat pumps generate 4 times energy of the driven power. That means that producing the same energy, the air source heat pumps exhaust the 1/4 of energy than the traditional appliance. Therefore, using the air source heat pumps for house heating and cooling will save at least 3/4 energy bill of your family.
