The vapor-compression refrigeration system uses R-134a as its working substance. The pressure upstream and downstream of the compressor are 28 psia and 130 psia respectively. Saturated liquid exits the condenser, and there is a 20 deg Fahrenheit sub cooling before the fluid is throtttled. For the conditions given calculate:

Find:

a.) The COP for the cycle with sub-cooling
b.) The COP of the cycle without sub-cooling
C.) The percent increase in refrigerating effect between part a.) and b.)
d.) the percent increase in required work between parts a.) and b.)
