Résumé

This paper shows a numerical simulation method to predict how a heat-pump system behaves in a variety of conditions and specifications. A model of heat-pump system, which consisted of a constant rotational speed compressor, a condenser, an evaporator, a decompression device and connecting tubes, was employed. Steady state governing equations for refrigerant flows and the state of refrigerant given by REFPROP 8.0 was solved by iterations. Characteristics of a heat-pump system with different ambient temperatures, different heat transfer coefficients of condenser caused by degradation, and different specifications due to retrofit by installing an additional condenser and replacing refrigerant were predicted by the simulation.
