    Class 1: This class includes refrigerants that cool by phase change (typically boiling), using the refrigerant's latent heat. Class 2: These refrigerants cool by temperature change or 'sensible heat', the quantity of heat being the specific heat capacity x the temperature change. They are air, calcium chloride brine, sodium chloride brine ...

    Commercial 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). [1] [2] Refrigeration is an artificial, or human-made, cooling method. [1] [2]

  7. Natural refrigerant - Wikipedia

    en.wikipedia.org/wiki/Natural_refrigerant

    When the pressure is released it undergoes rapid evaporation causing the temperature of the liquid to drop until it reaches its boiling point of -33 °C (-28 °F), which makes it useful in refrigeration systems. [25] Ammonia has been used frequently in industrial refrigeration since it was first used in the compression process in 1872.
