How Does Heat Pump Work?
Heat pumps transfer heat from one location to another using refrigerants and mechanical energy. They start by evaporating a low-pressure refrigerant, which absorbs heat from the heat source. The vaporized refrigerant is then compressed, increasing its temperature and pressure. In the condenser, heat is released to the heat sink, causing the refrigerant to condense into a high-pressure liquid. After passing through the expansion valve, the refrigerant becomes a low-pressure mixture and returns to the evaporator to repeat the cycle. Heat pumps can provide both heating and cooling by reversing the direction of heat transfer. The specific components and configurations may vary, but the fundamental principle remains the same.
