建立了CO2热泵热水器的仿真模型并进行了验证。建立了气体冷却器、蒸发器、压缩机和膨胀阀的组件模型，并仔细考虑了传热性能。为了验证仿真模型，使用实际的CO2热泵热水器（水加热能力：22.3kW;热水温度：90°C）进行实验。通过仿真和实验研究了进水温度和外界空气温度对系统特性的影响。其结果是，模拟结果和实验结果之间的COP的平均差异为1.5%。
A simulation model for the CO2heat pump water heater was developed and validated in this study. Component models of the gas cooler, evaporator, compressor, and expansion valve were constructed with careful consideration for the heat transfer performances. To validate the simulation model, experiments were carried out using an actual CO2heat pump water heater (water heating capacity: 22.3kW; hot-water temperature: 90°C). In simulations and experiments, the effects of the inlet water temperature and outside air temperature on the system characteristics were discussed. As a result, the average difference in COP between the simulation results and experimental results is 1.5%.
