The core working mechanism involves a refrigeration cycle that uses a refrigerant to absorb heat from an external source such as air, water, or ground. This absorbed heat is then compressed to increase its temperature and released indoors for heating purposes. In cooling mode, the process is reversed, removing heat from indoor air and releasing it outside.
One of the key efficiency benefits of this system is its ability to deliver more thermal energy than the electrical energy it consumes. This is measured through the Coefficient of Performance (COP), which is typically higher in heat pump systems compared to traditional heating methods. As a result, less electricity is required to maintain comfortable indoor temperatures.
Another important advantage is consistent performance in varying weather conditions. Modern heat pump systems are designed to operate effectively even in low outdoor temperatures, although efficiency may vary depending on environmental factors and system configuration.
