Question 3

In an ideal vapour compression refrigeration cycle, the enthalpy of the refrigrator before and after the evaporator are respectively 200 kJ/kg and 300 kJ/kg. The circulation rate of the refrigerant (in kg/min) for each 200 kJ/min of refrigeration is

Question 4

Consider a simple Vapour Compression cycle, the COP of this refrigeration cycle is 4. Find out the enthalpy at suction, if the enthalpy at discharge from the compressor = 1900 kJ/kg, and the enthalpy at exit from condenser = 800 kJ/kg respectively.
