An air conditioner operates exactly as a refrigerator; it removes heat from a cold place (a bedroom, for example) and conveys it to a warmer place (usually the outside). Quantities of practical importance in understanding the efficiency of air conditioners are the rate of heat removal and the electric power input to the unit (i. e., the electric energy consumed per unit time). Find an expression for the coefficient of performance K of an air conditioner that has a rate of heat removal H and a power consumption P.
