在热泵循环中采用混合制冷剂受到世界各国的重视并为此开展了研究工作。混合制冷剂首先运用于空调器中,并为此开发了在制冷系统中有效地分离和改变制冷剂组成的技术。研制了根据纯制冷剂推算混合制冷剂热力性质的计算机程序,并编制了VLE 图表和压力-焓图等。针对寒冷地区使用的热泵,研制了 R22和 R13B1混合制冷剂。采用混合制冷剂比 R22更能发挥由逆变器驱动的压缩机的优
The use of mixed refrigerants in the heat pump cycle has drawn the attention of all countries in the world and carried out research work for this purpose. Mixed refrigerants were first used in air conditioners, and to this end, technologies for efficiently separating and changing refrigerant compositions in refrigeration systems have been developed. A computer program for calculating the thermodynamic properties of mixed refrigerants based on pure refrigerants was developed. VLE charts and pressure-enthalpy diagrams were also prepared. For the heat pump used in cold areas, R22 and R13B1 mixed refrigerant has been developed. It is better to use a refrigerant mixture than R22 for the inverter-driven compressor
