都是一个原理
The theory behind a heat pump is that it uses electricity to transfer heat from a cooler space to a warmer space, rather than generating heat. This makes heat pumps more efficient than conventional heating systems, such as boilers or electric heaters.
Here's how a heat pump works:
Heating
During the heating season, a heat pump extracts heat from the outdoor air and moves it inside:
Liquid refrigerant passes through an expansion device, changing into a low-pressure liquid and vapor mixture.
The refrigerant goes to the outdoor coil, where it absorbs heat from the air and boils into a low-temperature vapor.
The vapor is compressed, which reduces its volume and causes it to heat up.
The hot gas is sent to the indoor coil, where the heat is transferred to the indoor air.
The refrigerant condenses into a liquid and returns to the expansion device.
Cooling
During the cooling season, a heat pump moves heat from inside the house to the outdoors.
Dehumidification
The cold evaporator collects moisture from the air, which dehumidifies the home.
Heat pumps can be combined with other heating systems, such as gas, in hybrid configurations.
They are most efficient when the temperature is above 40°F, and they consume more energy when the temperature drops below that
