   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.

9. Liquefaction of gases - Wikipedia

   en.wikipedia.org/wiki/Liquefaction_of_gases

   Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG, and in refrigeration and air conditioning.
