摘　　要：采用新型共沸混合工质KLB - 2 ,分别对原使用CFC1 2的热力膨胀阀和节流短管汽车空调系统进行了灌注式工质替代试验研究 ,试验结果表明 ,在相同的运行条件下 ,采用KLB - 2后系统与原CFC1 2系统相比制冷量较大 ,性能系数相近 ,KLB - 2可作为CFC1 2在汽车空调系统直接“灌注式”A new kind of azeotropic mixture refrigerant named KLB-2 is introduced. “Drop-in” experiments were carried out to compare the performance of the automotive air conditioning system with the CFC12. Compared to the CFC12 system, either the thermal-expansion-valve system or the CCOT (cycling clutch orifice tube) system with KLB-2 as working fluid in the same environment parameters (air temperature, solar radiation and the vehicle speed) has a larger cooling capacity and comparative power consumption.
