Solution:
A standard vapor-compression cycle can be represented on the P-h diagram below:

Given condensing temperature = 420C and evaporating temperature = -80C. Have a look at the program in the reference (provided) for R22, we can find:
h1 (sat. vapor) = 246.92 (kJ/kg), v1 = 0.06114 (m3/kg), s1 = 0.93908 (kJ/kgK), p1 = 1610 kPa
h3 (sat. ...
