Heat Pump Technology
How heat pumps work
Heat pumps are innovative devices that use electricity to extract heat from the outside air, ground, or water and transfer it into indoor spaces to warm them up. This process is achieved through the use of a refrigeration cycle that consists of four main components: the evaporator, compressor, condenser, and expansion valve.
When the heat pump operates in heating mode, the evaporator absorbs heat from the source, such as the outside air. The refrigerant then circulates and turns into a gas as it absorbs heat. The compressor increases the pressure and temperature of the gas before it is sent to the condenser. In the condenser, the heat is released into the indoor space as the refrigerant condenses back into a liquid. Finally, the expansion valve lowers the pressure of the refrigerant, and the cycle repeats.
Types of heat pumps
There are different types of heat pumps available in the market, including air-source, ground-source (geothermal), and water-source heat pumps. Air-source heat pumps extract heat from the outside air, while ground-source heat pumps utilize the steady temperature of the ground. Water-source heat pumps extract heat from a water source, such as a lake or pond. Each type has its own advantages and considerations, depending on factors like climate, installation area, and available resources.
