A simple saturation cycle of refrigeration system is operatingon R22. This system has an evaporator pressure of 350 kPa,condensing pressure of 1550 kPa and a discharge temperature of80°C. Degree of sub cooling of 8 K and degree of superheat of 5 K.Draw p – h diagram and calculate the following.
a. Refrigeration Effect.
b. Refrigerant mass flow rate, at a plant capacity of 196kW.
c. Power input into the compressor.
d. Coefficient of performance of the plant.
e. Compressor efficiency.
f. Total heat rejection.
g. Amount of condenser water required if LMTD of the watercooled condenser is limited to 8 K and the design ambienttemperature is 20°C wet bulb.
