A refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back.

The desired thermodynamic properties are a boiling point somewhat below the target temperature, a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form, and a high critical temperature. Since boiling point and gas density are affected by pressure, refrigerants may be made more suitable for a particular application by choice of operating pressure.

R-134a is the ideal refrigerant has good thermodynamic properties, is noncorrosive, safe and most importantly, it’s energy efficient.
