| Research Abstract |
Heat pump (HP) system have been diffused to household use as heating water supply of 90 degree C instead of boiler. Industrial heat pump systems is required to supply high-temperature heat source such as over 130 degree C. HP system needs to be driven using supercritical pressure refrigerant for supplying high temperature heat source. Plate heat exchanger (PHE) is mainly used to enhance heat transfer of liquid single-phase flow therefore heat transfer of supercritical pressure fluids flowing in PHE is not clarified enough. In this study, characteristics of heat transfer of supercritical pressure fluids are clarified in order to improving high-temperature HP system.
