A standard vapour compression refrigeration cycle machine uses R22 refrigerant, with the following conditions: Evaporator temperature (-5)C Condenser operates at constant P, condensate- saturated liquid at 30C Throttle expansion (i) Show the refrigeration cycle on P-H and T-S diagram. [2 marks] (ii) Estimate the work of compression (kJ/kg), the refrigeration effect, and the coefficient of performance. [11 marks] (iii) Estimate the refrigerant flow rate for an evaporator load of 5 kJ/s. [2 marks] Thermodynamic data
