vapor-compression refrigeration

Vapor-compression refrigeration is a process used to cool or refrigerate spaces and liquids. It works by circulating a refrigerant, a fluid that can easily change from liquid to gas and back. The process involves four main steps: the refrigerant absorbs heat inside the refrigerator (evaporator), compresses to a high-pressure gas (compressor), releases stored heat outside (condenser), and expands back into a liquid to continue the cycle. This continuous process effectively removes heat from the inside, maintaining a lower temperature. It's commonly used in refrigerators, air conditioners, and freezers.
