Asimple vapor compression refrigeration system uses r-22 as the working fluid. the evaporator pressure is 3 bar and the condenser pressure is 20 bar. the cooling load is 225 tons, the refrigerant exits the evaporator at 0 c and it exits the compressor at 160°c. (1 ton 3.517 kw). 2. a. plot and label all 5 points on the provided p-h diagram. b. determine the power input to the compressor, in kw. c. determine the rate of heat rejection from the condenser, in kw. d. determine the cop of the system. e. determine the compressor efficiency

An inventor claims to have developed a reversed heat engine (ie. a heat pump) which is able to deliver 10 kj heat into the room at 20°c from outside ambient temperature of -10°c by consuming only 2 kj electricity in winter. this claim is a)-impossible b)-possible only if the heat pump is ideal c)-practically possible d)-unable to be assessed as it depends on the working fluid used in the heat pump.
