Effect of heat transfer law on the performance of a generalized irreversible Carnot heat pump

The sole ineversibility considered in an endoreversible Carnot heat pump mo del is the loss of heat resistance between the heat pump and its surroundin g heat reservoirs. This paper presents a generalized irreversible Carnot he at pump model by taking into account several additional internal irreversib ilities of the heat pump. such as heat leakage, friction, turbulence and ot her undesirable irreversibility factors. This is done by means of a constan t parameter and a constant coefficient, together with the loss of heat resi stance. The relationship between the optimal heating load and the coefficie nt of performance (COP) is derived from a generalized heat transfer law Q = K Delta(T-n). The effect of heat leakage, internal irreversibility, and he at transfer law on the optimal performance of the generalized irreversible Carnot heat pump is investigated.
