Optimal Performance of a Class of Two-Heat-Source Heat Pumps with Piston

This paper studied a class of two-heat-source heat pumps with piston using an ideal gas working sub-stance and operating subject to irreversible heat transfer,and,it is supposed that the crank linked up withthe pump rotates uniformly. The fundamental optimum relation of the pumps was derived,and the relationwas used to discuss the various optimum performances of the pumps. Some instructive new conclusions forthe optimal design and operation of heat pumps were obtained.Furthermore,the theoretical method of finitetime thermodynamics and its important significance were emphasized.
