How does a heat pump work?
A heat pump is a system that transfers heat from one source to another, using a refrigerant. In general, there are two types of heat pumps: air-to-water and air-to-air.
The most common method of heat transfer is through a thermodynamic cycle using a compressor and an evaporator. This cycle begins when the refrigerant is compressed and heated, and the vapor is then sent to a condenser to transfer the heat to the water in the heating system.
Then, the refrigerant cools, and the process is repeated several times, until the desired temperature is reached. In the case of the air-to-water heat pump, the air is responsible for the transfer of heat from an external heat source, such as air, to the water in the heating system. In the case of the air-to-air heat pump, the heat is transferred to the indoor air.
“Heat pumps like to work with constant temperatures.The greater the temperature variations, the lower their performance.”
