Repeat problem 10-1-26 [OCX] with R-12 as the working fluid.
Problem 10-1-26
An ideal vapor-compression cycle uses R-134a as a working fluid and operates between the pressures of 0.1 MPa and 1.5 MPa. The refrigerant leaves the condenser at 30oC and the heat exchanger at 10oC. The refrigerant is then throttled to the evaporator pressure. Refrigerant leaves the evaporator as saturated vapor and goes to the heat exchanger. The mass flow rate is 1 kg/s. Determine
(a) The rate of heat removal from the refrigerated space per unit of the mass flow and
(b) The COP.
