Simulation of Miniature Vapor Compression Heat Pump System

Abstract

A prototype of miniature vapor compression heat pump system was introduced. On the basis of compressor, capillary, condenser and evaporator models, the steady-state model of air-to-water miniature heat pump system is developed with regard to energy and refrigerant inventory conservations among all these components. The results show that the relative error between prediction and experiment values is less than 5%, and the optimal match of condenser and evaporator lengths were obtained by simulation program.
