Résumé

As social awareness toward global warming grows, conventional refrigerants are regulated in stages. In order to select safe and environmentally friendly next-generation refrigerants for highly efficient heat pump system, a performance evaluation method by simulation technologies must be properly established due to limitation of experiment by extensive refrigerants. In this study, we first focused on refrigerant behavior inside a rotary compressor that strongly influences system performance, and developed detailed simulation models that accounts for the effects of leakage and heat transfer of refrigerant with lubricant. In addition, compressor performance tests were conducted to verify the validity of the model. Finally, heat pump cycle simulations were carried out using the compressor efficiencies, and the effects of different refrigerant properties such as R410A and Low GWP refrigerants on the characteristics and performance of the entire heat pump cycle was clarified.
