Abstract
The invention discloses a refrigeration device, comprising a refrigeration cycle which is at least composed of a compressor, a condenser, a swelling mechanism and an evaporator, wherein an R32 refrigerant and refrigerating machine oil are filled in the refrigeration cycle; the refrigerating machine oil is formed by mixing more than two of polyalkane glycol ether, polyvinyl ether, poly alpha olefin, alkylbenzene and mineral oil randomly; the second-layer separate temperature of one of the random more than two and the R32 refrigerant is lower than 10 DEG C below zero; the second-layer separate temperature of the other of the random more than two and the R32 refrigerant is higher than 10 DEG C below zero; the kinematic viscosity of the refrigerating machine oil is 2-100mm2/s when the temperature is 40 DEG C; more than one of antioxygen, acid catcher, antifoaming agent and extrusion antiwear agent is added into the refrigerating machine oil. The refrigerating machine oil and the R32 refrigerant have excellent dissolving capacity, the oil return property of the system is improved, and the reliability of the compressor and the system performance are improved.
Description
Technical field
The present invention relates to a kind of refrigerating plant.
Background technology
In recent years,, because traditional freon R22 cold-producing medium has destruction to ozone layer, via the use amount of international treaties regulation in Montreal to the R22 cold-producing medium, limit and future, stop using.In addition,, along with global air temperature warming, from global warming coefficient GWP, consider, the R410A cold-producing medium of high GWP etc. are final also can be substituted by the cold-producing medium of low GWP.Present industry is being found a kind of environmental protection refrigerant and is being developed.R290 is as natural series coolant, be subject to industry and pay close attention to, but due to its have flammable, can be quick-fried and requirement low charging amount be limited its use in present stage.And the R32 cold-producing medium is as not chloride one of hydro carbons and lower candidate cold-producing medium of global warming coefficient GWP fluoridized, with its have environmental protection, characteristics such as efficiency is high and cost is low and receive the concern of industry, and take R32, by the synthetic cold-producing medium of main body, all by industry, paid close attention to.
But because the chemical polarity of R32 cold-producing medium is very high, present existing mineral oil, alkylbenzene, synthetic POE oil, PVE wet goods etc. are because polarity is lower, can not be well and the R32 cold-producing medium mix.If adopt the refrigerator oil immiscible with cold-producing medium in refrigeration system, easily cause the layering of oil and cold-producing medium on evaporimeter in refrigeration system, refrigerator oil is not easy to get back in the compressor of refrigeration system, thereby causes the moving component oil starvation of compressor, affects the reliability of compressor.Simultaneously, the oil that is trapped in evaporimeter can affect the heat exchanger effectiveness of evaporimeter again, causes the decrease in efficiency of refrigeration system.Therefore, from the service life of the performance of refrigeration system and compressor, consider, should select and R32 cold-producing medium fine refrigerator oil that mixes when the low temperature.
Principle according to " similar mixing " in chemistry, want to find the oil that mixes with the R32 cold-producing medium, will improve the polarity of oil, but, for refrigerator oil,, due to the increase of polarity, tend to cause the decline of viscosity, affects the reliability of compressor; Therefore will guarantee the polarity of refrigerator oil, guarantee that refrigerator oil has certain viscosity again, be the major subjects of the suitable refrigerator oil of exploitation R32 cold-producing medium.
Summary of the invention
Purpose of the present invention aims to provide a kind of good with the intermiscibility R32 cold-producing medium, can improve the oil return of system, improves the reliability of compressor and the refrigerating plant of systematic function, to overcome weak point of the prior art.
A kind of refrigerating plant by this purpose design, comprise the kind of refrigeration cycle that is formed by compressor, condenser, expansion mechanism and evaporimeter at least, be filled with R32 cold-producing medium and refrigerator oil in this kind of refrigeration cycle, it is characterized in that refrigerator oil is by any two or more the mixing in polyalkane glycol ethers, polyvinylether, polyalphaolefin, alkylbenzene and mineral oil.
Two layers of separation temperature of described arbitrarily two or more wherein a kind of and R32 cold-producing mediums are below-10 ℃, and two layers of separation temperature of two or more another kinds and R32 cold-producing medium are more than-10 ℃ arbitrarily.
The kinematic viscosity of described refrigerator oil is 2～100mm in the time of 40 ℃
2/ s.
Add more than one in antioxidant, sour agent for capturing, defoamer and extruding antiwear additive in described refrigerator oil.
So-called two layers of separation temperature refer to: obtain mixture after at first R32 cold-producing medium and refrigerator oil being mixed by certain ratio, then mixture is enclosed in the glass pressure container, then the glass pressure container is put in insulating box, mixture is cooling gradually from room temperature, while being cooled to uniform temperature, mixture starts to occur two phase stratification from the solution of single mixing, and the temperature that two phase stratification occurs is designated as two layers of separation temperature under this ratio; By measuring different blending ratios, just can obtain two layers of separation temperature curve, the highest separation temperature point is designated as two layers of separation temperature of refrigerator oil and R32 cold-producing medium here.
After the present invention adopted above-mentioned technical scheme, refrigerator oil and R32 cold-producing medium had good solvability, guaranteed that the refrigerator oil in kind of refrigeration cycle is got back to compressor, thereby improved the oil return of system, improved reliability and the systematic function of compressor.
