【摘要】 针对制冷剂HCFC22的替代问题,课题组提出了一种适用于家用空调的环保型混合制冷剂 HFC32／HFC152a／HFC125。在REFPROP 7．0基础上,课题组对此混合制冷剂的热力学性质和制冷性能进行了理论分析。并利用空气焓差试验台对HFC32／HFC152a／HFC125混合制冷剂的制冷性能进行了实验研究, 结果表明新的制冷剂性能与HCFC22接近而优于R407C。考虑到新制冷剂的可燃性问题,课题组对其进行了可燃性研究。综合现有的实验结果,表明此混合制冷剂是一种理想的潜在替代制冷剂。更多还原

【Abstract】 A new mixture refrigerant HFC32/HFC152a/HFC125 was provided to alterative the refrigerant HCFC22 in this paper. Based on the software REFPROP 7.0, thermodynamic properties and refrigeration performance of the new mixture refrigerant were analyzed in theory. And air enthalpy method was used to analyze its refrigeration performance in experiment. Compared with R407C, the performance of the new refrigerant was certified to be excellent to replace HCFC22. Also the flammability of this new refrigerant was analyzed. As a result of the analyzing in theory and experiment, this new mixture refrigerant is an ideal potential substitute of HCFC22.更多还原
