For a vapor compression refrigeration system using R-22 as refrigerant, condenser outlet temperature is 40OC and evaporator inlet temperature is -20OC. In order to avoid flashing of refrigerant, a liquid-to-suction vapor heat exchanger is provided where liquid is sub-cooled to 26OC. The refrigerant leaves the evaporator as saturated vapor. The compression process is isentropic. Draw the schematic diagram and show the corresponding P-h diagram. Find the power requirement and coefficient of performance if capacity of the system is 10 kW at -20OC

Question
For a vapor compression refrigeration system using R-22 as refrigerant, condenser outlet
temperature is 40OC and evaporator inlet temperature is -20OC. In order to avoid flashing of
refrigerant, a liquid-to-suction vapor heat exchanger is provided where liquid is sub-cooled to 26OC.
The refrigerant leaves the evaporator as saturated vapor. The compression process is isentropic.
Draw the schematic diagram and show the corresponding P-h diagram. Find the power requirement
and coefficient of performance if capacity of the system is 10 kW at -20OC
