Abstract

The invention provides a refrigerant composition with low GWP (Global Warming Potential) value, and the refrigerant composition consists of fluoroethane(R161) and 2,3,3,3-tetrafluoropropene (HFO-1234yf). The preparation method of the refrigerant composition is as follows: physically mixing the components under liquid phase based on corresponding proportions. The refrigerant composition provided by the invention, which has zero ODP (Ozone Deplete Potential) value and quite low GWP value, can be applied to directly replacing R22 in a household air conditioners/heat pump systems and the like.

Description

technical field [0001] The invention belongs to the field of refrigerants, and relates to a refrigerant composition, in particular to a refrigerant with low global warming potential (GWP) which is used in refrigeration and air-conditioning systems such as household air conditioners / heat pumps to replace difluorochloromethane (R22) Refrigerant composition. Background technique [0002] In September 2007, the "Montreal Protocol" Conference of the Parties held in Montreal, Canada, reached a new resolution, which stipulates that developed countries will completely stop the production and consumption of non-raw material R22 in 2020, and developing countries including China , to freeze the production and consumption of non-raw material HCFCs (about 70% of which are R22) at the average level of 2009 and 2010 in 2013, and complete the complete phase-out in 2030. Compared with the original phase-out schedule, the entire phase-out process has been greatly advanced. At present, about ...
