Refrigeration. Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature).

This cycle involves four key phases: evaporation, compression, condensation, and expansion. Evaporation: The refrigeration cycle begins in the evaporator with a low-pressure liquid refrigerant absorbing heat from its surrounding environment. As the refrigerant absorbs heat, it changes state from a liquid to a vapor.
Refrigeration systems typically operate in the range of −5 °C (for Freon systems) to as low as −45 °C (for ammonia (NH 3) systems). They can use a variety of refrigerants and fluids in addition to Freon and ammonia, …
Cold thermal energy storage is largely used in offices, hospitals, schools, and churches, due to the high energy consumption of air-conditioning [37].
