The detailed characteristic evaluation of CO_2 heat pump water heater has not been enough investigated. Therefore, the purposes of this study are to clarify the detailed characteristics by the simulation and to confirm the validity of this simulation model by comparing the simulation results with experimental ones. First, The simulation models of each devices are built, Second, the static analysis of CO_2 heat pump water heater using these simulation models is carried out. In the simulation, the effects of the inlet water temperature and the outside air temperature on COP, the heat exchanger duty, the refrigerant flow rate and the pressure are discussed. The experimental setup is real machine whose water heating capacity is 22.3kW and outlet water temperature is 90℃. As a result, the validity of this simulation model was confirmed and the detailed characteristics were clarified.
