Description
Technical field
The present invention relates to refrigerant technology field, specially a kind of Envinonment protection type energy-saving refrigerant of essential safety.
Background technology
Chlorofluorocarbon, such as dichlorodifluoromethane (dichlorodifluoromethane) and monochlorodifluoromethane
(monochlorodifluoromethane), for example, being already used to the refrigerant as air-conditioning, refrigerator etc..Such ingredient
Also be used to cleaning or cleaning precise part double duty such as semiconductor chip.Chlorofluorocarbon is comparatively safe due to theirs
Not flammability, high stability and hypotoxicity be widely used.However, it is known that chlorofluorocarbon helps to damage the earth
Ozone layer, thus dangerous influence can be generated to global environment.For this reason, the production of chlorofluorocarbon and using also
Through continuously decreasing, only a small amount of chlorofluorocarbon is using now.
It is used as refrigerant and detergent now with the substitute of various chlorofluorocarbons.Hydrofluorocarbon
(Hydrofluorocarbons, HFCs), for example, HFA 134a and 1,1,1- trifluoroethane is presently used for substituting
Chlorofluorocarbon.However hydrofluorocarbon (HFCs) also causes the degeneration of ozone layer, although smaller.In addition, hydrofluorocarbon (HFCs) is as temperature
Room gas, the problem of global warming can be caused.
It currently studies and replaces chlorofluorocarbon and hydrofluorocarbon using hydrocarbon mixtures, since they are to environment
Influence be relatively benign.Traditional hydrocarbon components are usually used in combination with chlorofluorocarbon, hydrofluorocarbon etc., because
This, can still generate environmental risk to a certain degree.Therefore, it is necessary to hydrocarbon compositions independently to make as refrigerant
With.
A kind of hydrocarbon refrigerant is designed only to be made of the alkanes mixed.With definite meaning.
Invention content
To achieve the above object, the present invention provides following technical solution：A kind of Envinonment protection type energy-saving refrigerant of essential safety,
Using high-purity propane and iso-butane, normal butane, the wherein ratio of propane is 38%-40%, and the ratio of iso-butane and normal butane is
60%-62%, and mixture is together, then selects three kinds of nitrogen, methane and ethane gases, above-mentioned raw materials are after first separation
Gas phase after cooling for gas-liquid two-phase state, using second separator it is separated go out liquid phase produce through liquid phase throttle valve it is cold,
Residual air cools down using subcooler, liquefies, then the production that throttles is cold, finally obtains environment friendly refrigerating fluid.
As a kind of preferred technical solution of the present invention, the ratio of the iso-butane and normal butane is 1/3 to 4/3.
As a kind of preferred technical solution of the present invention, the nitrogen, methane and ethane pass through purification process.

Fluoroethane is raw material, is catalyzed using 2% Ru/C, then dechlorination obtains refrigerant.
As a kind of preferred technical solution of the present invention, the dechlorination process passes through metal dechlorination or hydrogenation-dechlorination.
As a kind of preferred technical solution of the present invention, the environment friendly refrigerating fluid can also pass through trifluorobichloroethane original
Material, makees catalyst using amine, reuses and obtains 1,1 after metallic copper is reacted with trifluorobichloroethane, Isosorbide-5-Nitrae, and 4,4- hexafluoros-
2- butylene.
As a kind of preferred technical solution of the present invention, the amines catalyst is methylamine, ethamine or diethylamine.
Compared with prior art, the beneficial effects of the invention are as follows：Its physical and chemical index and existing freon R22 and R134a phases
It is close, and charging amount only has the 38%-40% of freon, since its molecular weight is small, good flowing properties, evaporation potential bigger, system
It is cold with obvious effects, and to ozone layer without destruction, greenhouse effects are almost O, more energy saving, environmental protection, since raw material have easily
Explosive characteristic is fired, increases combustion adjuvant and easy detonator in mixture, and increases acid smell warning gas, allows product in the application more
Add safe and reliable.
