I need help on the following question: The vapour compression cycle (picture provided), utilises the refrigerant R134a flowing at 0.05 kg s-1. Assuming that the compression is adiabatic and reversible. If the actual input power to the compressor is 2 kW, then: 1. You need to determine the theoretical input power to the compressor and the heat transfer (Φ) to theevaporator. Take the enthalpies h1, h2, and h3 to be 238.41, 263.68 and 81.5 kJ kg-1 (use the 'NH3 Refrigeration Table' where you can find online). 2. You need to determine the coefficient of performance based on your answer to the previous question (1). 3. You need to determine the compressors mechanical efficiency.

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).
