which refrigerant has the lowest boiling point in atmospheri

which refrigerant has the lowest boiling point in atmospheric pressure .R-502; R-134a,R-22,R-12.

Solution

Boiling points of various refrigerants are as follows

R-502=-45.17 ^o C

R134a=-26.074 ^o C

R22=-40.80 ^o C

R-12=-29.8 ^o C

among all above refrigerants,R-502 has lowest boiling point
