自1987年《蒙特利尔协定》制定以来,世界各国均在加紧对冰箱制冷剂R12替代工质的开发和研究.目前,家用冰箱循环工质R12的替代物主要有R134a和MP39.其中,MP39为共沸三元混合物,其组成为R22/R152a/R124,成分比例为53:13:34(体重:体重).主要分析两种替代物用于制冷系统时的循环性能、系统主要部件变化.1 R134a、MP39与R12物性及热力性能比较作为冰箱循环工质R12的替代物,必须满足以下三个条件:①满足作为制冷剂的一般要求;②具有与R12相似的热力性质;③符合《蒙特利尔协定》规定,即对大气环境的抵公害性.表1和表2分别为R134a、MP39和R12的物性及热力性能比较.

Since the formulation of the "Montreal Agreement" in 1987, countries around the world have stepped up the development and research on the replacement of refrigerant R12 in refrigerators. At present, the main substitutes for R12 in household refrigerators are R134a and MP39. Among them, MP39 is a common refrigerant. Boiling ternary mixture, its composition is R22/R152a/R124, and the composition ratio is 53:13:34 (weight:weight). The cycle performance and the changes of the main components of the system when the two substitutes are used in the refrigeration system are mainly analyzed. 1 R134a 、Comparison of physical and thermal properties between MP39 and R12 As a substitute for R12, which is a refrigerant circulating fluid, it must meet the following three conditions: ①Meet the general requirements as a refrigerant; ②Have similar thermal properties to R12; ③Comply with the Montreal Agreement Regulations, that is, the pollution resistance to the atmospheric environment. Table 1 and Table 2 are the comparison of physical properties and thermal properties of R134a, MP39 and R12, respectively.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used gas chromatography to determine R134a, a new medium for refrigerator refrigerants, with satisfactory results.
