Question

The values of enthalpy at the beginning of compression, at the end ofcompression and at the end of condensation are 185 kj/kg, 210 kj/kg and 85kj/kg respectively. what is the value of the cop of the vapour compressionrefrigeration system?

Answer 1

"The values of enthalpy at the beginning of compression, at the end of compression and at the end of condensation are 185 kj/kg, 210 kj/kg and 85kj/kg respectively.

Here according to the question,

h1 = 185 KJ/kg

h2 = 210 KJ/kg

h4 = 85 KJ/kg

COP = {(h1-h4)/(h2-h1)}

= {(185-85) / (210-185)}

= 100/2s

COP = 4.

Thus, the value of the cop of the vapour compression refrigeration system is 4.
