Mechanical Engineering

A single stage simple vapr compression refrigeration cycle usingR12 refrigerant is operating at a condenser temperature of 40degrees C and an evaporator temperature of -5 degrees C. If thecompressor is a reciprocating type compressor with 4 cylinder,rotating at 1800 RPM, has a cylinder diameter of 5cm, stroke lengthto diameter ratio of 1.4, and clearance ratio of 5%. Assume apolytropic index to be 1.13. 1- Sketch the cycle flow diagram, andidentify the states on the P-H diagram. Calculate the refrigerationeffect, refrigeration capacity in TR, the compressor power in HP,the cycle COP, the temperature of the refrigerant after exiting thecompressor, and the cycle refrigeration efficiency.
