A heat pump is a refrigerator that is used to pump thermal energy from cold reservoirs (cold air) to hot reservoirs (hot air). Heat reservoir is an ideal system with heat capacitors so large that it can absorb or provide heat without significant temperature changes. Meanwhile, you might need to call the best air conditioning repair columbia sc when you want to install a new heat pump at home.

The heat pump system does not only function to cool or maintain a low heat source temperature. But it can also drain heat energy into an object or heat absorber to raise the temperature or maintain its temperature at a high level well. In thermodynamics, refrigerators and heat pumps are relatively the same.

The difference lies only in the working process. Heat machine is a device that functions to convert heat energy into mechanical energy. For example on a car engine, the heat energy from burning fuel is converted into the motion energy of the car. However, in all heat engines, we know that the conversion of heat energy to mechanical energy is always accompanied by exhaust gas, which carries a certain amount of heat energy. Thus, only a portion of the heat energy results from the combustion of the fuel that is converted to mechanical energy. Another example is in a power plant; coal or other fuel is burned and the heat energy produced is used to convert water into steam. This steam is directed to the blades of a turbine, making these blades rotate. Finally, this mechanical rotation energy is used to drive an electric generator.

In many uses, for the same machine can be used as a refrigerator and also as a heat pump. In some situations, both the cooling effect at one temperature level and the effect of heating at other temperatures can be cooled, and thus the system will operate simultaneously as a refrigeration machine and as a heat pump.
