vapor-compression cycle
The vapor-compression cycle is a process used in refrigeration and air conditioning to transfer heat. It involves four main steps: the refrigerant (a special fluid) absorbs heat and vaporizes as it passes through the evaporator, then the compressor compresses the vapor to a higher pressure and temperature. The high-pressure vapor moves through the condenser, where it releases heat and condenses back into a liquid. Finally, an expansion device reduces the liquid's pressure, allowing it to absorb heat again in the evaporator. This continuous cycle cools the environment efficiently.
