A simple vapor compression cycle develops 15 tons of refrigeration using ammonia as refrigerant and operating at condensing temperature of 24 C and evaporating temperature of -18C and assuming compression are isentropic and that the gas leaving the condenser is saturated, find the power per ton. Properties of Ammonia: h1=hf = 312.87 kJ/kg h2= 1665 kJ/kg At -18C hg = 1439.94 kJ/kg
