soojuspumbasüsteem

Soojuspumbasüsteem is an Estonian term referring to a heat pump system. A heat pump system is a device that transfers thermal energy from a source of heat to a destination called a "heat sink". Heat pumps are increasingly used for heating and cooling buildings, as well as for domestic hot water preparation. They operate by harnessing naturally occurring thermal energy present in the environment, such as air, ground, or water.

The fundamental principle of a heat pump system is based on a thermodynamic cycle, typically involving a refrigerant. The refrigerant circulates through a closed loop, undergoing phase changes that allow it to absorb heat from the colder source and release it at a higher temperature to the warmer destination. This process is the reverse of a refrigerator, which moves heat from inside to the outside.

There are several types of heat pump systems, categorized by the heat source they utilize. Air-to-air heat pumps extract heat from the outside air and transfer it to the indoor air. Ground-source heat pumps, also known as geothermal heat pumps, utilize the stable temperature of the earth to exchange heat. Water-source heat pumps draw heat from nearby bodies of water like lakes or rivers. The efficiency of a soojuspumbasüsteem is measured by its Coefficient of Performance (COP) for heating and its Energy Efficiency Ratio (EER) for cooling, which indicate the ratio of useful heating or cooling provided to the work energy consumed.
