In refrigeration process, a region is cooled and the temperature was maintained at -15oC. The cooling water used in the refrigeration is 25oC. If the refrigerant is HFC-134a, and the heat transfer temperature difference is 10oC, (a) calculate the COP of the Carnot Refrigerator. (b) What is the COP and (c) mass flowrate if the rating of the refrigeration process is 100,000 kJ/h and the efficiency of the compression is 0.75
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.
