An ammonia ice plant operates between condenser and evaporator temperature of 35 and -16°C respectively. It produces 5 tons of ice per day from water at 20°C to ice at -10°C. The NH3 enters the compressor is superheated by 5°C. Use the following table and find (1) Capacity of the plant in Tons (ii) Mass flow rate of refrigerant in kg/s (iii) COP (°C) vapor P (bar) Liquid The kJ/kg Sf kJ/kg.K ng kJ/kg $g Vg kJ/kg.K m3/kg -16 2.26 107.83 10.4397 1425.28 5.5693 0.5303 135 13.5 347.5 1.2821 1471.43 4.93 0.0906 Take Cp of ammonia vapor as 2.8 kJ/kg.k
