Description
Technical field
It is specifically a kind of to be applied in air-conditioning system substitute monochlorodifluoromethane the present invention relates to a kind of refrigerant
Environment-protecting mixed refrigerating agent preparation method.
Background technology
A large amount of with freon refrigerant are used, and the environmental problem such as depletion of the ozone layer, greenhouse effects is further exacerbated by, state
Border society also puts into effect in succession《Montreal Protocol》、《The Kyoto Protocol》Making for freon is limited etc. a series of treaties
With.Monochlorodifluoromethane is used as a member in freon, although possess preferable refrigerating capacity, but it has destruction ozone concurrently simultaneously
Still occupy very big proportion in layer, shortcoming higher GWP, and the Domestic air conditioning market of monochlorodifluoromethane at home, because
This finds suitable refrigerant to substitute the vital task that monochlorodifluoromethane is current refrigerant market for a long time.
Propane is considered as to substitute the ideal refrigerant of monochlorodifluoromethane, its good refrigeration effect, natural environmental-protective, but
Inflammable and explosive the characteristics of, causes it not promote the use of, if part fire retardant is added in propane to suppress its combustibility, and
The thermal parameter of the mix refrigerant of formation is close with monochlorodifluoromethane, thus can directly substitute monochlorodifluoromethane.
The flame retardant effect of HFC-134a preferably, propane is mixed with HFC-134a, obtained mix refrigerant does not damage the ozone layer, to temperature
Room effects are smaller, and the critical piece of refrigerating plant need not be modified just can directly fill replacement the chlorine of difluoro one
Methane.
Due to there is flammable propane still containing larger specific gravity in the mix refrigerant, leaked when occurring refrigerant
When, it is same that there is very big potential safety hazard if handled not in time.If added in the mixture of propane/HFC-134a few
The warning gas of amount, when leaking, people can be aware of the very first time, and take measures to solve in time, so as to ensure
The person and property safety of user.Thiophane has foul odour beastly as odor additive, is diffused in air
In be easily therefore easily perceived by humans, because thiophane has anesthetic effect, thus application when can not largely use, the present invention just with four
Hydrogen thiophene is added in the mixture of propane/HFC-134a as warning gas, and guarantee is provided for the security of the lives and property of people,
And improve the performance of refrigerant.
The content of the invention
In view of this, the present invention provides a kind of a kind of replacement monochlorodifluoromethane for solving or partly solving the above problems
Environment-protecting mixed refrigerating agent preparation method.
