A vapour compression refrigeration plant, which uses refrigerant-134aoperates at an evaporator pressure of 240 kPa and a condenser pressureof 1.2 MPa. The refrigerant leaves the evaporator at 0oC and exits thecondenser at 40oC. The two-stage compression is isentropic. Therefrigerant that leaves the condenser is throttled to a flash chamber with asaturation temperature of 15.71oC. Saturated vapour is extracted from theflash chamber and mixes with the refrigerant that leaves the low-pressurecompressor, before entering the high-pressure compressor. Saturatedliquid from the flash chamber is throttled to the evaporator. If therefrigeration load is 500 kW, determine the: a) mass flow rate of refrigerant through the condenser (kg/s),b) mass flow rate of refrigerant extracted from the flash chamber (kg/s)c) Power required by the low pressure compressor (kW).
