Note:Use-the relevant-chart-for-each-preblem------ 5. For a vapour compression refrigeration system using R-22 as refrigerant, condenser outlet temperature is 40°C and the evaporator inlet temperature is -20'C. In order to avoid flashing of the refrigerant, a liquid-suction vapour heat exchanger is provided where liquid is subcooled to 26°C. The refrigerant leaves the evaporator as saturated vapour. The compression process is isentropic. Find the power requirement and coefficient of 1 performance if capacity of the system is 10 kW at -20 °C. Show the cycle on temperature- entropy and pressure-enthalpy diagrams. The specific heat of vapour refrigerant is 1.03 kJ/kg K.
