Refrigeration

Refrigeration is the method or technique of lowering or keeping temperatures of objects or space below ambient temperature by using various techniques or devices. Refrigeration involves changing energy to transfer heat from a low-temperature medium into one with a higher temperature. Most refrigeration processes require refrigerant that absorbs or releases heat by undergoing phase changes (liquefaction or vaporization operation) at various pressures. Refrigeration comes in different types and techniques, including absorption, heat compression, evaporation, and more. Refrigeration is essential in multiple sectors and industries like the storage of medical supplies, food preservation, chemical manufacture, electronics aerospace, and so on. Here are more definitions and the history of Refrigeration.
