what is refrigeration

Refrigeration is the process of cooling a space, substance, or system to lower and/or maintain its temperature below the ambient one. It involves the removal of heat from a low-temperature medium and its transfer to a high-temperature medium, traditionally driven by mechanical means. Refrigeration has various applications, including household refrigerators, industrial freezers, cryogenics, and air conditioning. It is used in industries, agriculture, transportation, and food preservation to inhibit the growth of microorganisms and prolong the shelf life of food products
