Refrigeration is a process that removes heat from a designated area to lower its temperature, commonly used in household appliances like refrigerators and freezers. This technology is essential for preserving food, maintaining comfort in buildings, and supporting various industrial processes. The refrigeration cycle typically involves the compression of a refrigerant, which absorbs heat from the environment and releases it elsewhere. This cycle is crucial in many applications, from air conditioning systems to large-scale industrial refrigeration setups, ensuring that perishable goods remain fresh and safe for consumption.
