摘要： Difluoromethane (R32) is of current interest as a partial replacement for chlorodifluoromethane (R22) refrigerant heretofore widely used in vapor compression refrigeration systems. R32 has, however, proved to be more reactive than is desirable with the zeolite A adsorbent-desiccant compositions used in such systems to prevent corrosion and freeze-up problems. The sodium cation form of a zeolite having the crystal structure of zeolite B is found to be an effective adsorbent for that purpose and to be significantly less reactive with the R32.
摘要翻译：目前，二氟甲烷（R32）作为蒸发压缩制冷系统中广泛使用的氯二氟甲烷（R22）制冷剂的部分替代品目前令人感兴趣。然而，R32已被证明比在这种系统中使用的沸石A吸附剂 - 干燥剂组合物所希望的更有效，以防止腐蚀和冷冻问题。发现具有沸石B的晶体结构的沸石的钠阳离子形式是用于该目的的有效吸附剂，并且与R32的反应性显着更低。

摘要： In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise HFC-32, HFC-125, HFO-1234yf, HFC-134a, and CO2. The refrigerant compositions are useful in processes to produce cooling and heating, in methods for replacing refrigerant R-R-22, and in refrigeration, air conditioning or heat pump systems. These inventive compositions are non-flammable and match cooling performance for R-22. The compositions as described herein have unexpected flammability properties.
