摘　　要：为提高制冷空调和热泵性能,分别选取CO2,R134a,R1234yf和R11制冷剂,以单级循环和双级循环为研究途径,分析了不同工况下,排气压力、蒸发温度和冷凝温度等因素对循环性能的影响。研究结果为制冷空调和热泵优化设计及新产品的开发提供理论依据。In order to improve the pertormance of air conditioning and heat pump, the refrigerant, of C02, R134a, R1234yf and Rll were selected, the single stage cycle and two stage cycle were studied. The cycle performance were analyzed in different situations such as discharge pressure, e- vaporation temperature and condensing temperature. Some fundamental data were obtained for op- timum design and developing the products of refrigeration air condition and heat pumps.
