Description
Technical field
The present invention relates to refrigeration agent, relate in particular to a kind of environmental protection refrigerant and preparation method thereof.
Background technology
Because the signing of Montreal protocol and Kyoto Protocol; Various countries to refrigeration agent CFC-12 (methyl chlorofluoride) surrogate require increasingly high; Except the refrigeration agent that will look for novelty does not damage this basic demand ozonosphere, the refrigeration agent that also will look for novelty has alap GWP (global warming potential).
The substitute of refrigeration agent CFC-12 mainly is HFC-134a (1,1,1, the 2-Tetrafluoroethane) in the market.Though HFC-134a has good thermal performance; ODP (ODP) is 0, and is not flammable, but because its GWP is 1370; Bigger; Do not meet the requirement of current global energy-saving and emission-reduction, so it is more outstanding to press for the development environment performance, the while thermal performance novel refrigerant poor unlike HFC-134a.
HFC-1234yf (2,3,3, the 3-tetrafluoeopropene) has good thermal performance, and ODP is 0, and GWP is merely 4, and environmental performance is excellent, though have certain combustibility, belongs to the 2L class, and combustibility is not strong.Under identical automative air conditioning operating mode, the coefficient of refrigerating performance of HFC-1234yf is lower than HFC-134a, and the unit volume refrigerating duty is also on the low side, but the exhaust temperature of HFC-1234yf is very low, has very big saturated aq specific volume simultaneously.
The basic physical properties of DME (dme) is similar with HFC-134a, and ODP is 0, and GWP is 0, has certain combustibility, belongs to the 3rd type.Under identical automative air conditioning operating mode, the cycle efficiency of DME is superior to HFC-134a, and has very big saturated aq specific volume, can reduce the filling quantity of refrigerant of system, and DME not only can use synthetic oil simultaneously, can also use MO.
Though HFC-134a, HFC-1234yf and three kinds of refrigeration agents of DME all have deficiency separately when using separately; If but HFC-134a, HFC-1234yf and DME are mixed use; Form a kind of novel environmental protection refrigerant; Can combine three's advantage separately, at utmost reduce unfavorable factor.
In the prior art, Chinese patent file CN 1285699C (200410084844.5) discloses a kind of with fluoroethane (HFC-161), 1,1-C2H4F2 C2H4F2 (HFC-152a) and 1,1,1, the ternary composition that 2-Tetrafluoroethane (HFC-134a) is formed; Chinese patent file CN 101765648A (200880100202.6) discloses a kind of with 1,2,3,3, the mixture that 3-five fluorine propylene (HFC-1225ye) and other compounds are formed; Chinese patent file CN 101851490A (201010198685.7) discloses a kind of with 2,3, and 3; 3-tetrafluoeopropene (HFC-1234yf), trans-1,3,3; 3-Tetrafluoroethane (HFC-1234ze (E)) and 1, the mixture that 1-C2H4F2 C2H4F2 (HFC-152a) is formed; Chinese patent file CN 101864277A (201010196224.6) discloses a kind of with 2,3,3,3-tetrafluoeopropene (HFC-1234yf), 1, the mixture that 1-C2H4F2 C2H4F2 (HFC-152a) and dme (DME) are formed; Chinese patent file CN 102066518A (200980122002.5) discloses a kind of with 2,3,3,3-tetrafluoeopropene (HFC-1234yf), 1,1,1,2-Tetrafluoroethane (HFC-134a) and 1, the mixture that 1-C2H4F2 C2H4F2 (HFC-152a) is formed; It is a kind of 1,1,1 that Chinese patent file CN 102083935A (200980125796.0) discloses, 2-Tetrafluoroethane (HFC-134a), 2,3,3, the mixture that 3-tetrafluoeopropene (HFC-1234yf) is formed.
Disclosed refrigerant composition earl august eugene lund ian robert exists or GWP is higher or not directly charge and be applied to the HFC-134a system or combustibility more greatly, maybe can not be used mineral wet goods shortcoming in the above-mentioned patent; Therefore; Need exploitation have better refrigeration performance, with better compatible and the new refrigerant of existing system with better environmental-protecting performance.
Summary of the invention
The invention provides the environmental protection refrigerant of a kind of low GWP (global warming potential); This refrigeration agent does not only destroy atmospheric ozone layer; And the Greenhouse effect that produce are littler, have simultaneously with HFC-134a quite even excellent more thermal parameter and thermal property.
A kind of environmental protection refrigerant, by 2,3,3,3-tetrafluoeopropene, dme and 1,1,1, the 2-Tetrafluoroethane is formed, and each constituent mass per-cent is: 2,3,3,3-tetrafluoeopropene 20 ~ 90%, dme 5 ~ 25% and 1,1,1,2-Tetrafluoroethane 5 ~ 55%.
