The air conditioner (a kind of vapour-compression refrigerator) in a 1600-cc car, which works on a pseudo-ideal reversed Rankine cycle, uses R-134a, the isentropic rotary-com-pressor of which consumes power at a rate of 1.5 kJ/s bringing the R-134a from 2.017 bar to 12 bar by compression. The cold space is a heat exchanger (using a hamster wheel as a blower) that cools atmospheric air from the outside temperature of 303 K down to 283 K and blows it into the car. Assume the start of compression process is state point 1. The refrigerant at evaporator exit is dry saturated vapour and saturated liquid at the condenser exit. Draw the schematic and T-s diagrams for the cycle. (a) What is the mass flow rate of the R-134a ()? (b) What is the low-temperature heat transfer rate?
