Question

how to find the property of state 4???

The vapor-compression refrigeration system shown in Figure 1 below uses R134aas its working substance. The pressures upstream and downstream of the compressor are 28 psia and 130 psia respectively. Saturated liquid exits the condenser, and there is a20 degree F sub-cooling before the fluid is throttled. For the conditions given calculate: The COP for the cycle with sub-cooling The COP of the cycle without sub-cooling The percent increase in refrigerating effect between part (a) and (b) The percent increase in required work between parts (a) and (b)

Explanation / Answer

h4 with subcooling=35.77 h4 witout = 42.67
