A vapor-compression refrigeration system

Reference no: EM13691626

Problem- A vapor-compression refrigeration system, using ammonia (R-717) as the refrigerant, is operating with and evaporator temperature of -5 degree C and condenser temperature of 40 degree C. It is desired to determine the influence of raising the evaporator temperature to 5 degrees C while holding condenser temperature at 40 degrees C. Calculate the percent changes in

a) Refigeration effect per kg refrigerant flow rate

b) C.O.P.

c) Heat of compression

d) Theoretical power requirements

e) Rate of heat rejected at the condenser, anticipated due to raising the evaporator temperature.

I am thankful to receive an expert help to solve the above problem
