In industrial fields, heat source over 130°C are widely needed, and for this the development of industrial high-temperature heat pump systems has been promoted. For the heat release process in such the heat pump systems, the authors have studied on cooling heat transfer of refrigerants at supercritical pressures in chevron-type plate heat exchangers (PHEs). In this study, to establish a simulation model which estimates the cooling heat transfer coefficient of supercritical pressure refrigerants flowing in the chevron-type PHEs, a CFD analysis was carried out. The results of this analysis agreed well with the experimental results including the data in pseudocritical region where the physical properties of the refrigerant change rapidly with temperature. From the simulation results, characteristics of temperature distribution and heat flux distribution in the chevron PHE were discussed.
