a) A reversible air-conditioner (AC) removes 1000kJ/s of heat from a room maintained at 25C. The air-conditioner rejects the heat to the environment at 40C. The air-conditioner is driven by a reversible heat engine which receives heat from a reservoir at 200C and rejects the heat to the environment kept at the same temperature of 40C. (i) Give the schematic diagram for the arrangement. Determine the following. (ii) Input power to the AC. (iii) Heat received by heat engine from the reservoir. (iv) Efficiency of the heat engine. a) A reversible air-conditioner (AC) removes 1000kJ/s of heat from a room maintained at 25C. The air-conditioner rejects the heat to the environment at 40C.
