Description
Technical field
The present invention relates to a kind of refrigerant, more particularly to a kind of energy-saving environment protection mixed refrigerant and preparation method thereof.
Background technology
It is well known that the ozone layer in earth overhead just uses pernicious gas days such as " freon " (CFC, HCFC) multiple one by the mankind
Day it is lost, seriously endangers the mankind and various biological existence.In the prior art, an atmosphere difluoromethane (CHClF2, R22) and
R502 (azeotropic mixture being made of R22 and Rll5) has been widely used as the system in air-conditioning, refrigerator, refrigerator etc refrigerating plant
Cryogen;Meanwhile halogenated hydrocarbons is also widely used in the fields such as fire-fighting, cleaning, production foamed polymer.
In recent years, EU countries disables one after another various contains " fluorine " (CFC, HCFC) preparation.In China, State Council also ratifies reality
Shi Liao《China is phased out ozone depleting substances national scheme》, in this scheme, clear stipulaties all trades and professions should be
Stopped using before in July, 2007 and various contain " fluorine " (CFC, HCFC) refrigerant.Therefore, numerous scientific workers, are engaged in refrigeration work
The engineers and technicians of journey technological development research just put into a large amount of man power and materials, find better performances and to atmospheric ozone layer without
The novel refrigerant of destruction, and require to can be suitably used for refrigeration plant and parts.Through developmental research for many years, it was found that one
A little refrigerant materials, but be all difficult to solely be used as mono- 22 substitutes of R, then, the numerous and confused research and development for putting into Diversity refrigerant.
For environmental protection refrigerant currently on the market, have a disadvantage that:
One Rl 34A (CH2FCF of first generation environmental protection refrigerant:), it is a kind of environmental protection refrigerant in transition period.It has will not
The advantages of destroying earth's ozone layer;But its shortcomings that, is:1st, Energy Efficiency Ratio is very low, and compared with using CFC, it can increase energy consumption
40%;2nd, existing compressor and hot channel, must be reequiped using Rl 34A, increases production cost.
Second generation environmental protection refrigerant-R407C, R410A, although they and 100% nothing " fluorine " (CFC, HCFC), necessary
Used on it have changed compressor and hot channel, and the lubricating oil for maintenance of special expensive must be used.Energy Efficiency Ratio is with fluorine
Leon is close.
Because before this, the refrigeration unit of most of air-conditioning and refrigeration all uses systems of the R12 or R22 containing CFC or HCFC
Agent.If using the refrigerant of the first generation (R134A) or the second generation (R407C, R410A) instead, new engine just must be reequiped or former
The capacity for having machine reduces.Then, it is badly in need of finding one kind and meeting world's environmental requirement now, can also continue to use original dress
It is standby, it is not necessary to spend the cost added, can more achieve the purpose that environmentally friendly mixed type refrigerant in a short period of time.
The content of the invention
The present invention provides a kind of energy conservation and environmental protection to make up the above-mentioned deficiency of the prior art, does not destroy ozone layer, does not produce
The mix refrigerant that greenhouse effects simultaneously can be used instead directly on existing refrigeration machine.
The present invention solve the above problems used by technical solution be:A kind of energy-saving environment protection mixed refrigerant is provided, should

The preparation method of energy-saving environment protection mixed refrigerant according to the present invention, it is characterised in that:Container Stirring in step E
Time is 1.5, Bu Shi.
The preparation method of energy-saving environment protection mixed refrigerant according to the present invention, it is characterised in that:Step F includes following substep
Suddenly:
Fl, be sufficiently stirred rear undelayed, and semi-finished product by the gross are directly dispensed as early as possible;Packing delay, turn to perform fZ;
Before f2, packing, when stirring 0.21.3 is small again, cylinder of steel is rolled after filling, is sufficiently mixed it.
In the present invention:C tramples CH2FCF3(R 1 34a)、CH2FCF3(R125) Ozone Depletion Potential ODP is 0, no
Ozone layer can be destroyed.In the present invention, suitable CH2FCF3(Rl 34a) and CH2FCF3(R 1 25) mixing after, become R42IA or
R42lB, is the mixture of azeotropic, no longer separates.The present invention in performance, as adiabatic condensation temperature under boiling point, critical-temperature, 375 pas,
The value of refrigerating capacity etc. is all approached with R-22, and required lubricator is also identical.The present invention can not redesign or reequip it is existing cold
R-22 is substituted under conditions of jelly system comprehensively, compared to the energy that R-22 can also save 12.5-25%.
Compared with the second generation (R407C, R410A) refrigerant, it is advantageous in that the present invention:
Compared with the second generation (R407C, R410A) refrigerant, it is advantageous in that the present invention:Consumption rate is less than R-
407C10%:The pressure of required compressor is less than R-407C.
The present invention is heat-resisting azeotropic mixture, is sent out with being stored in transport in cylinder in the state of liquid in any refrigeration system
In the case of raw leakage, it refrigerant of the present invention can be used directly to add, systemic-function do not influenced.
The present invention is used as a kind of efficient refrigerant, and a most obvious efficiency is that temperature is higher, and refrigerating capacity is higher.This
Invention from 3 DEG C or so of butter and the storage temperature of fruit, to -30 DEG C of medium storage temperature under all operational excellences;The present invention
Compressor can also be started when -40 DEG C, in the winter time using Teat pump boiler when it is particularly practical.Many examples show, make
Worked with the compressor of the present invention under lower cryogenic temperature, the maximum operational efficiency for reaching pointed can be approached.The present invention
It is the refrigerant being particularly suitable for be had been found in terms of refrigeration.
The present invention has drawn the experience in first and second generation, has both been environmental protection refrigerant, more can substitute R12 or R22 immediately and
It is not required to that original machine is replaced or changed.The present invention not only conforms to world's environmental requirement, can also continue to use original equipment,
The cost added need not be spent, can more achieve the purpose that environmental protection in a short period of time.
It is of the invention to be advantageous in that relative to the prior art:Absolutely without " fluorine " (CFC, HCFC).
It is of the invention to be advantageous in that relative to the prior art:CFC or HCFC can be directly replaced, it is any without needing to change
