Here are the solutions to the problems: 4) An ammonia refrigerating machine has working temperature of 35^ in the condenser and 15^ in evaporator. Assume two cases: I. dry compression, and II. Wet compression. Calculate for each, the following (i) theoretical piston displacement per ton refrigeration (ii) theoretical horsepower per ton refrigeration, and (iii) the coefficient of performance. Ammonia (R717) Properties (approximate values from tables): At Evaporator Temperature (T_e = 15^): P_e = 7.29 bar *
