Heat exchanger 2. Apart from vapor compression refrigeration cycles, refrigeration can also be achieved by a gas cycle, most commonly reversing the ideal (and closed-loop) Brayton Cycle. Below figure shows the case. COP can be calculated by the same way (work input is the net input considering the presence of the turbine). In such a cycle operating with air, compressor inlet is - 15°C and 1XX kPa. The compression ratio is given as [12-(XX/10)]. Turbine inlet temperature is [28+(XX/5)]°C. Obtain the lowest temperature in the cycle and the COP of the refrigerator. Strictly use cp as 1005 and k=c»/c, as 1.4. XX is the last 2 digits of your student number.
