一种可直接充灌替代R22的制冷剂
摘要：
本发明提供一种应用于家用空调/热泵等系统中直接充灌替代R22的制冷剂组合物。该制冷剂由五氟乙烷(R125)、1，1，1，2-四氟乙烷(R134a)和二甲醚(DME或RE170)组成；其制备方法是将上述各组分按其相应的配比在液相下进行物理混合。本发明完全符合环境保护的要求，ODP值为零，GWP值较低，热工性能及参数与R22十分接近，压力及压缩机排气温度较R22低，替代时无需改动或更换现有R22系统的任何部件及润滑油，可实现直接充灌，且循环性能与R22相当或略高。
摘要（英）：

The invention provides a refrigerant composition capable of being directly filled for replacing R22 in systems such as a household air conditioner/ heat pump and the like. The refrigerant comprises pentafluoroethane (R125), 1,1,1,2- tetrafluoroethane (R134a) and dimethyl ether (DME or RE170); and the preparation method of the refrigerant comprises the following step of physically mixing all the components under a liquid phase in the corresponding proportions. The refrigerant completely meets the requirement of environment protection and has the ODP (Ozone Destruction Potential) value of zero and low GWP (Global Warming Potential) value; the thermodynamic engineering performance and the parameters of the refrigerant are very close to R22; the pressure and the exhausting temperature of a compressor are lower than those of R22; any parts and the lubricating oil of the traditional R22 system do not need to be changed or replaced when R22 is replaced with the refrigerant; the refrigerant can be filled directly and has good cycle performance same as or slightly higher than R22.
