Description
The present invention relates to working medium used in the recycle system of refrigeration plant, adoptable near-azeotropic polybasic mixed working medium in the refrigeration cycle of especially realizing ideal.
For many years, for the operation material of realizing the refrigeration plant recycle system is the ideal cycle of temperature-variable heat source with the sensible heat of fluid, it is the Lorenz circulation, reach energy-conservation effect, take into account simultaneously and improve factor of environmental, relevant scholar, expert and the scientific research personnel of various countries done some valuable research work to binary or multiple non-azeotropic refrigerant, still can say to have positive effect to promoting scientific research development.For instance, research has often also obtained some achievement in research, but failed to obtain due popularization for various reasons in the process of refrigeration of refrigeration plant aspect the binary non-azeotropic mixed working medium; Abroad report is few and at the picture that studies well aspect the preparation multiple non-azeotropic refrigerant, domestic then news has indivedual reports or information, wherein, more representative is that on December 9th, 1989 is by turning round and look at the patent of invention that young Mr. army is applied for, application number 89105235A inscribes one's name and is " working medium of Gu thermodynamics circulation thermodynamic system ".The applicant has proposed the refrigeration agent of five types quaternary zeotrope formation in that application, or claims the quaternary non-azeotropic mixed working medium.The material of forming this class Gu Shi working medium then is respectively by R12, R13, R22, R23, R115, R152
aAnd normal butane, Trimethylmethane is formulated, and thinks that therefrom the non-azeotropic mixed working medium that constitutes uses in process of refrigeration and have energy-saving effect.But up to the present, no matter the above-mentioned patent application that turns round and look at young Mr. army releases the still actual report that uses from Jie of theory, does not all have compellent foundation.
Below we do the brief explanation of analyzing with regard to some character of non-azeotropic mixed working medium and azeotropic mixed working medium:
Physical properties with regard to constituent, so-called " zeotrope working medium " is that solution evaporates under certain pressure or during condensation, its vaporization temperature or condensing temperature and concentration are all changing, and so-called " azeotropic mixed working medium ", its solution evaporates under certain pressure or during condensation, its vaporization temperature and condensing temperature all remain unchanged, azeotropic mixed working medium is when evaporation or condensation thus, its gas phase all has identical component with liquid phase, and non-azeotropic mixed working medium is in evaporation or during condensation, and the component of its gas phase and liquid phase changes.Equally, under the constant situation of envrionment temperature, if pressure change, that not the gas phase of azeotropic mixed working medium and the component of liquid phase be constant, and the component of the gas phase of non-azeotropic mixed working medium and liquid phase is changing.For this reason, the multiple non-azeotropic refrigerant that comprises quaternary can produce some more formidable defectives in being applied to process of refrigeration; One in the refrigeration equipment use, if cooling agent one has leakage, no matter be to leak gas phase mixture or liquid phase mixture, all can make left mixing medium in refrigeration equipment be different from original component; They are two years old, if mixing medium injects the process of ice chest or packaged air-conditioner one by one from bigger container, pressure in the container is diminishing gradually, the component of its gas phase and liquid phase also just changes, and the result is that its mixing medium can't keep identical component in the refrigeration system of each ice chest or little conditioner.Here do not consider also that non-azeotropic mixed working medium, can be by the situation of stratified liquid in container after static for some time.If this thing happens, then be fed into the mixing medium in the refrigeration system of each single refrigerator or little conditioner, its component just has bigger difference.Refrigerator and the little air-conditioning produced in batches just can not keep stable quality.After these problems come out in actual use, be worth our deep thinking really.So whether can adopt azeotropic mixed working medium, and avoid taking place above-mentioned disadvantage? according to actual tests except can selecting energy-conservation two yuan of little azeotropic type mixing mediums for use, prepare the azeotropic type mixing medium of the polynary component of obvious energy-saving effect, its success ratio is extremely small.
The object of the invention is to overcome the defective of above-mentioned multiple non-azeotropic refrigerant, and in 2-4 unit mixing medium, according to a certain percentage or certain amount, adding is to all easily affine working medium of each component in a certain mixing medium, be referred to as " affine working medium ", can make the physical properties of this mixing medium be in close proximity to azeotropic mixed working medium.Such mixing medium should belong to nearly azeotropic mixture or mixing medium in the zeotrope.
Comprise fluorine Lyons in the near-azeotropic mixture working medium of the present invention and be made up of mixing medium and affine working medium, wherein the main component of mixing medium is:
a，R12，R13;
b，R11，R114，R115;
C, R123, R125, R134a, R152a, R22, R23, three groups of R32 etc.
Above a, b, the listed various refrigeration agents of three groups of mixing mediums of c all can be used as the major ingredient of energy-saving near-azeotropic mixture working medium, its molar content is 20～90%, among a wherein, two groups of b listed refrigeration agent be to atmospheric ozone layer have the havoc effect should be as far as possible usefulness less, preferably need not.
The affine working medium that is adopted in the working medium described in the present invention has:
d，R142
b，R152
a，R32;
e，R125，R124;
f，R225
a，R225
b;
g，R141
b，R141，R113，R115。
Above d, e, f, any two classes of g all can cooperate as a pair of affine working medium, but in the mixing medium of different important component, then will select optimum composition and best proportioning.We find d in the trial-production of practice, e, and general usage quantity is the 0.1%-30% molar percentage, f, g, the general use is 0.1%～10% molar percentage.Usually adopt two kinds of suitable affine working medium, add in the proper ratio in the mixing medium, all be beneficial to for the energy-saving effect of whole refrigeration system and homogeneity, the homoeostasis of mixing medium itself.In addition, the ratio of the concrete consumption of product relates to the saturated vapor pressure of the near-azeotropic mixture working medium that finally prepares, and should try one's best near the saturated vapor pressure of the single working medium that is substituted.Above new refrigeration agent is used under the physical construction that does not change or seldom change original refrigeration equipment system.
Confirm reasonably to select for use the component of mixing medium and affine working medium and the near-azeotropic mixture working medium that proportioning constituted through overtesting.Homogeneity, the homoeostasis that keeps itself there is very big benefit, thereby makes refrigeration system reach ideal circulation and the bigger energy-saving effect of generation.Simultaneously, also can reduce some has the use of fluorine Lyons kind of havoc effect to atmospheric ozone layer, reaches the effect that improves physical environment.
Fig. 1 adopts the carnot's working cycle of the single working medium of R22 and Lorenz round-robin to compare;
Fig. 2 is that the carnot's working cycle and the Lorenz round-robin of the ESR22 near-azeotropic mixture working medium through repeatedly preferably mating generation 22 compares;
Fig. 3 is with R22, R115, R152
aEach 30% mol ratio is as the main component of mixing medium, and with the carnot's working cycle and the round-robin comparison now of labor opinion as the mixing medium of affine working medium of R142b and each 5% mol ratio of R142.
Near-azeotropic mixture working medium of the present invention is that the above different substances of quaternary mixes, and that preferably selects for use has following six kinds:
