Problem Set #5: Refrigeration

Problem 5: 1

An ideal vapor refrigeration cycle uses Freon-12 as the working fluid. The condensing temperature is 35 oC and the evaporation temperature is -10 oC. Determine: (a) the coefficient of performance for the cycle; (b) the power required to produce 1 ton of refrigeration; (c) the circulation rate of fluid for each ton of refrigeration

Answer:

(a)	COP = 5.03
(b)	Power/ton = 0.699 kW/ton
(c)	circulation rate = 1.858 kg/min
