Heat pumps or heat pumps are devices that have the ability to transfer energy. Pumps transfer the energy they take from the outside and transfer it to the inside of buildings, i.e. to places where heating or cooling is needed. The heat pump consists of the following parts: compressor, expansion valve, gas (for example R410) or heat transfer fluid, evaporator and steam condenser. Energy from renewable sources (earth, water, air) enters the pump evaporator. Then through the pipe system, the gas that has taken on the energy goes to the compressor where the pressure and temperature increase. The next step occurs in a welded exchanger system where the heat of the gas is transferred to the heating/cooling system. After giving up the heat, the gas returns to its original temperature and goes back to the evaporator to start the process again. In order to classify them more simply according to criteria of general interest, we divide them according to: energy sources from nature - free energy sources they use, power and characteristics. For example, according to the energy they use (free/natural) we divide them into: air-water heat pump, ground-water heat pump and water-water heat pump. Heat pumps have a combination of two meanings in their name. The first word indicates the energy used, and the second the energy transmitter in the installation
