The full-load capacity and COP of an air conditioner are 25 tons and 3.5 respectively. The part-load degradation factor is 0.3. The air conditioner is installed in a building whose cooling load varies from 8 kW to 85 kW. (i) Plot a graph of the power input to the air conditioner versus the cooling load. (ii) If two such air conditioners are to be operated in an optimal manner in a building whose cooling load varies from 10 kW to 170 kW, plot the variation of the power input to the chillers with the cooling load.
