Abstract
The invention relates to a mixed refrigerant containing trifluoroiodomethane, which is formed by physically mixing a component 1, a component 2 and a component 3, wherein the component 1 is trifluoroiodomethane having the function of inhibiting combustion and explosion, the component 2 is 1,1,2,2,-tetrafluoroethane, and the component 3 is propylene; and in the mixed refrigerant, the content of the component 1 is 1-10 wt%, the content of the component 2 is 20-40 wt%, and the content of the component 3 is 50-75 wt%. The ODP (ozone depletion potential) value of the mixed refrigerant is zero, the GWP (global warming potential) value is much smaller than that of a conventional HFC (hydrofluorocarbon) working medium, and the mixed refrigerant has favorable lubricating oil intersolubility; and thus, the mixed refrigerant can directly substitute an R22 working medium without great changes in the refrigeration system. Since the mixed refrigerant has the combustion inhibiting component, the refrigerant has greatly lower flammability and is even non-flammable, so that the safety of the refrigeration system is greatly enhanced.
Description
Technical field
The invention belongs to refrigerant art, particularly a kind of mix refrigerant containing CF3I.
Background technology
R22(HCFC22, CHF
2cl) be a kind of refrigeration agent of widespread use in air-conditioning system, there is extraordinary thermal property, and there is higher efficiency.But along with the discovery of depletion of the ozone layer mechanism and Greenhouse effect problem, R22 is owing to having the ODP(ozone depletion value of diving) value and the higher latent value of GWP(Global warming) value is put into progressively superseded ranks.
The Substitute Working Medium of R22 mainly contains two classes now: a class is natural medium, and as hydrocarbons (HCs), ODP is zero, and GWP is very low, but itself has very strong combustibility; One class is synthetic hydrogen fluorohydrocarbon (HFCs), and as R134a etc., ODP is zero, and flammable not as HCs, part HFCs has fire retardation, but GWP is higher, and has lubricating oil solubility problem.In pure working medium, be difficult to search out complete satisfactory R22 alternative refrigerant, in this case, mix refrigerant becomes the study hotspot of R22 surrogate.
It is R410A and R407C that application at present mixes Substitute Working Medium more widely, and the ODP value of the two is zero, met the protection requirement to ozonosphere, but GWP value is but very high.Aspect refrigerating efficiency (COP), the two 0.9～1.0 times of being R22 while not doing Optimized Matching.At alternative aspect of performance, the operating pressure of the two is all higher than R22, wherein the condensing pressure of R410A than R22 height approximately 57%, be not suitable for directly filling in the system of using R22.
Summary of the invention
The object of the invention is to according to the basic demand of R22 alternative refrigerant and the screening principle of mix refrigerant, propose a kind of mix refrigerant containing CF3I, this mix refrigerant has safety, environmental protection and lubricating oil and has the advantages such as good mutual solubility.
Technical scheme of the present invention is as follows:
Mix refrigerant containing CF3I provided by the invention, it is comprised of following component 1, component 2 and component 3 through physical mixed:
Described component 1 is for having the CF3I (R13I1) of combustion and explosion suppression effect;
Described component 2 is HFA 134a (R134a);
Described component 3 is propylene (R1270);
In described mix refrigerant, described component 1 content is 1-10wt%, and described component 2 content are 20-40wt%, and described component 3 content are 50-75wt%;
In described mix refrigerant, in described component 2, can also comprise 1,1-C2H4F2 C2H4F2;
In described mix refrigerant, in described component 2, can also comprise dme.
The mix refrigerant that is a kind of safety and environmental protection containing the mix refrigerant of CF3I provided by the invention, it has following plurality of advantages: ODP value is zero, and life-time service can not damage ozonosphere; The GWP value of CF3I, propane, propylene, dme and 1,1-C2H4F2 C2H4F2 is all very low, thus the present invention containing the GWP of the mix refrigerant of CF3I much smaller than R22 and present widely used R410A and R407C; Operating pressure and R22 are suitable, without existing refrigeration system is done to large change; Also, because the mix refrigerant containing CF3I of the present invention contains flame-retardant composition, can reduce the combustibility of refrigeration agent, the security of refrigeration system is improved.
