Description

一种环保制冷剂 技术领域
本发明属于制冷剂领域， 涉及一种制冷剂组合物， 尤其涉及一种应用于家用空调 /热泵 等制冷空调系统中替代 R22的制冷剂组合物。 背景技术
根据《蒙特利尔议定书》的原本规定，发达国家将于 2030年完全停止非原料性质的 R22 生产和消费， 发展中国家（包括我国）将于 2040年停止非原料性质的 R22生产和消费。但 2007年 9月在加拿大蒙特利尔召开的 《蒙特利尔议定书》缔约方大会达成的最新决议中规 定， 发达国家将于 2020年完全停止非原料性质的 R22生产和消费， 包括中国在内的发展中 国家，要在 2013年将非原料性质 HCFCs (其中约 70%是 R22)的生产和消费量冻结在 2009 年和 2010年的平均水平上， 2030年完成全面淘汰。相比原来的淘汰时间表， 整个淘汰进程 大大提前， 而目前国内生产和应用的约 80%的家用空调 /热泵等系统采用 R22作制冷剂， 由 此可见， R22的替代形势非常严峻且替代品的研究幵发迫在眉睫。
当前， 国内外市场上 R22的主要替代品为 R410A (R32/125)、 R407C (R32/ 125/ 134a), R417A (R125/134a/600 ) 和 R422D (R125/134a/600a)等， 但这些替代品并不理想， 例如， R410A与 R22系统不兼容， 压力高， 替代 R22时必须更换新的压缩机和两器， 增加了替代 成本： R407C 的能效较低， 滑移温度较大， 在替代过程中需要对系统部件和润滑油等作改 动或更换； R417A (R125/134a/600 ) 或 R422D (R125/134a/600a) 在直接充灌替代 R22时 制冷效率降低、 制冷量下降、 压力升高等。 而且， 这些替代品的温室效应潜能值 （GWP) 还很高， 例如， R410A为 2100, R407C为 1800， R417A为 2300, R422D为 2700, 随着全 球变暖趋势的日益加剧， 当前整个国际社会都在关注和控制温室气体的排放。 根据欧盟已 通过的含氟温室气体（F-gas)控制法规的要求： 自 2011年 1月 1日起， 欧盟将禁止新生产 的汽车空调使用 GWP值大于 150的制冷剂：在 2011年 1月 1日至 2017年 1月 1日的六年 间， 在用汽车空调将按比例逐歩淘汰 GWP值大于 150的制冷剂； 自 2017年 1月 1日起， 将禁止所有汽车空调使用 GWP值大于 150的制冷剂。 由此可以看出， 国际社会已经开始制 定相关法规控制温室气体的排放， 虽然目前只针对汽车空调领域， 而未涉及家用空调 /热泵 领域， 但整个制冷空调行业抑制温室气体排放， 出台相应法规， 禁止使用高 GWP值的制冷 剂将是大势所趋。
现有技术中， 专利申请 CN 200810082668.X公幵了以氟乙烷、 二氟甲垸、 五氟乙垸和 碳氢化合物等物质组成的混合物； 专利申请 US 2008029733公开了以五氟乙垸、 四氟乙垸 和碳氢化合物等物质组成的混合物；专利申请 CN 200710156803.6公开了以氟乙垸、二氟甲 垸和碳氢化合物等物质组成的混合物； 专利申请 WO 2007102815公开了以五氟乙烧和四氟 乙垸组成的混合物：专利申请 CN 03116856.6公开了以氟乙垸、五氟乙垸和二氟甲烷组成的 三元混合物；专利申请 CN 00121158.7公开了以丙垸、五氟乙烷和二氟甲垸组成的三元混合 物： 专利申请 US 7276176和 US 7258813公开了以五氟乙垸、 1，1，1,2-四氟乙垸和异丁垸组 成的混合物； 专利申请 CN 93102698.9公开了以二氟甲垸、 1,1，1，2-四氟乙烷和选自 1，1-二氟 乙垸、 1，1,卜三氟乙垸、 丙垸等组成的混合物； 专利申请 CN 91112767.4、 US 649356和 WO 9211339公幵了以五氟乙烷、二氟甲垸和四氟乙垸组成的混合物； 专利申请 CN 91112768.2、 US 412974和 WO 9105027公开了以五氟乙垸和二氟甲垸组成的二元混合物； 专利申请 US 6783691公幵了以二氟甲烷、五氟乙烷、 1,1,1,2-四氟乙烷和碳氢化合物组成的混合物； 专利 申请 US 56245%公开了以二氟甲垸、 五氟乙烷和碳氢化合物组成的混合物。 这些申请中的 混合物基本都是为了替代 R22而研究开发， 但这些混合物存在或制冷效率低下， 或与 R22 系统不兼容， 或具有较大的滑移温度， 或价格昂贵及替代费用高等问题， 而且， 这些混合 物都含有 GWP值较高的组分， 所组成的混合物具有较高的 GWP值， 从长远来看， 并不符 合抑制温室气体排放的要求， 一旦新的控制温室气体排放法规出台， 这些混合物的应用将 会受到极大限制。 发明内容
