ther f Q4 An experiment is conducted on Refrigeration Trainer Apparatus Components (TQ 2015) todemonstrate the performance of a vapor compression refrigeration or heat pump cycle. The datacollected following the procedure of appendix 1 is given in Table Q4.(a) Explain the principle of refrigeration system and its components in not less than 200words.(b) Result Analysis and cycle performanceConvertgauge pressures (PHIGH PLOW) into values of absolute pressure (PHIGH ABS PLOW-ABS) as used in the Pressure-Enthalpy chart.V Plot the state points of the refrigerant on the Pressure-Enthalpy chart as follows (refer thePressure-Enthalpy in Appendix 1):Point 1: use the measured values of TR1 and absolute pressure of the low-side(PLOW_ABS)-Point 2: use the measured values of TR2 and absolute pressure of the high-side(PHIGH_ABS)-Point 3: use the measured value of TR3 and the pressure of the condensation process(equivalent to the absolute pressure of the high-side (PHIGH ABS)).Point 4: use the measured value of vaporization pressure (equivalent to the absoluteEC_AM~_.-pressure of the low-side (PLOW_ABS)) and the constant enthalpy of the expansionprocess (hR3 = hR4).Draw lines to connect points 1-2, 2-3, 3-4 and 4-1 to achieve a complete refrigerationcycle.Determine the cycle performance by calculating the work of compression, the heatingeffect, the refrigerating effect and the two heating and cooling COPS using formulas (6,10, 12, and 13) also the superheat and sub-cooling degrees using formulas (14 and 15).(:-(c) Discuss the pressure-enthalpy chart with reference to the points (1, 2, 3 & 4).
