Abstract: PURPOSE: A refrigerant mixture added one component of HFC-227ea, R-600a, HFC-236ea, R-600, HFE-134, and HFE-245 to a mixture of HFC-32 and HFC-152a additionally is provided which exhibits performance similar to HCFC-22. CONSTITUTION: A refrigerant mixture free from ozonosphere destruction danger, which can be used as a substitute for chlorodifluoromethane comprises difluoromethane(CH2F2, HFC-32) as a first component, 1,1-difluoroethane(CF2CHF2, HFC-152a) as a second component and one component selected from the group consisting of 1,1,1,2,3,3,3-heptafluoropropane(CH3CHFCF3, HFC-236ea), isobutane(CH(CH3)2CH3, R-600a), 1,1,1,2,3,3-hexafluoropropane(CHF2CHFCF3, HFC-236ea), butane(C4H10, R-600), bis(difluoromethyl)ether(CHF2OCHF2, HFE-134), and pentafluoroethylmethylether(CF3CF2OCH3, HFE-245) as a third component. The composition of HFC-32, HFC-152a and HFC-227ea is 40 to 70% by weight, 5 to 50% by weight and 0 to 40% by weight respectively.
Abstract translation: 目的:提供一种制冷剂混合物,其另外将HFC-227ea,R-600a,HFC-236ea,R-600,HFE-134和HFE-245的一种组分加入到HFC-32和HFC-152a的混合物中, 类似于HCFC-22。 构成:可用作氯代二氟甲烷替代物的无臭氧层破坏危险的制冷剂混合物包括作为第一组分的二氟甲烷(CH 2 F 2,HFC-32)作为第二组分的1,1-二氟乙烷(CF 2 CHF 2,HFC-152a) 和选自1,1,1,2,3,3,3-七氟丙烷(CH 3 CHFCF 3,HFC-236ea),异丁烷(CH(CH 3)2 CH 3,R-600a),1,1,1 ,2,3,3-六氟丙烷(CHF2CHFCF3,HFC-236ea),丁烷(C4H10,R-600),双(二氟甲基)醚(CHF2OCHF2,HFE-134)和五氟乙基甲基醚(CF3CF2OCH3,HFE-245) 零件。 HFC-32,HFC-152a和HFC-227ea的组成分别为40〜70重量%,5〜50重量%,0〜40重量%。
