Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and is only used for explaining the present invention, and is not considered as limiting the invention.
The machine oil 3 according to the ... of the embodiment of the present invention for compressor is described referring to Fig. 1-Fig. 3 and with its compression
Machine 100.
In compressor 100, needing to be filled with makes moving component in compressor 100 have the machine oil 3 of enough viscosity to lubricate, and also needs
It is filled with cooling refrigerant, that is, needs the mixture for being filled with machine oil 3 and refrigerant, so that compressor 100 can be transported normally
Turn.Wherein, the machine oil 3 for being used for compressor can be refrigerator oil 3.
Machine oil 3 according to the ... of the embodiment of the present invention for compressor includes：First polyol ester and the second polyol ester, the
One polyol ester is synthesized by pentaerythrite with the polyhydric aliphatic acid of carbon number 6~12, and the second polyol ester is by neopentyl glycol, three hydroxyl first
At least one of base propane and dipentaerythritol polyalcohol and oleic acid synthesis.In some specific examples, the first polyalcohol can
With the polyol ester that the aliphatic acid for being 9 by the aliphatic acid and/or carbon number of pentaerythrite and carbon number 8 synthesizes, the second polyol ester can
To be the polyol ester synthesized by least one of neopentyl glycol, trimethylolpropane and dipentaerythritol polyalcohol and oleic acid.
The mass ratio of first polyol ester and the second polyol ester is w, is met：5/95≤w≤95/5.For example, more than first
The mass ratio w=27/73 of first alcohol ester and the second polyol ester either w=53/47 or w=82/18.
For example refrigerant is difluoromethane and five fluoromethane mix refrigerants, the liquid of the first polyol ester and the refrigerant
Mixture dissolves each other completely at 15~30 DEG C, and the liquid mixture of the second polyol ester and the refrigerant is in oil content (weight
Than) be 3%~70% when, which occurs two separate at 70 DEG C or less.
For example refrigerant is difluoromethane, difluoromethane and five fluoromethane mix refrigerants, when machine oil 3 and the refrigeration dosage form
At liquid mixture oil content (weight ratio) be 3%~40% when, which two layers occur at 70 DEG C or less
Separation；When the liquid mixture that machine oil 3 and the refrigerant are formed is when oil content (weight ratio) is 60% or more, which mixes
Object mixes at 20 DEG C~40 DEG C.
Fig. 3 is to be measured according to professional standard " 0699 refrigerator oils 3 of SH-T and refrigerant compatibility test method ".By the party
The refrigerator oil 3 that method measures in the hatched example areas of Fig. 3, i.e., is formed with refrigerant liquid mixture when machine oil 3 and the refrigerant
For liquid mixture when oil content (weight ratio) is 3%~40%, which occurs two separate at 60 DEG C or less, separation
Have different solubility respectively two layers, wherein containing liquid coolant it is more for rich refrigerant layer, it is more for richness containing refrigerator oil 3
Oil reservoir.
Here, the situation of machine oil 3 and the liquid mixture of refrigerant formation in oil content (weight ratio) 70% or more,
It occurs mainly in inside compressor 100, in order to ensure that 100 compression mechanism 2 of compressor can adequately be lubricated, it is desirable that freezing
Machine oil 3 and refrigerant are wanted to dissolve each other, and such machine oil 3 can fully be lubricated compression mechanism 2.If occurred in the region
If layering, it is rich refrigerant layer to be lubricated to compression mechanism 2, can not be to compressor since the viscosity of rich refrigerant layer is too low
Structure 2 carries out sufficient lubrication, may lead to 100 integrity problem of compressor.Therefore it is required that when the liquid of machine oil 3 and refrigerant formation
In oil content (weight ratio) 60% or more, which mixes body mixture at 20 DEG C~40 DEG C.
Since the machine oil 3 of the present invention has lower solubility with refrigerant, can use in systems less
Refrigerant reach the ability of refrigerating plant requirement.
The present invention by refrigeration equipment performance the study found that the first polyol ester is matched with the second polyol ester as above-mentioned
Machine oil 3 than mixing has lower solubility, and viscosity is enough, in the case where 3 viscosity of machine oil reduces, even if making
Less refrigeration dose is enclosed in cool equipment, refrigeration equipment has higher Energy Efficiency Ratio, is shown in Table described in 1.
Table 1
The viscosity of the refrigerator oil 3 of present invention kinematic viscosity at 40 DEG C be 68mm2/s hereinafter, it is optimal be 32mm2/s~
56mm2/s, because 100 temperature range of operation of compressor is minimum can to reach -20 DEG C, to avoid causing due to low refrigerant solubility
Viscosity is excessively high under oil low-temperature, therefore it is required that oil viscosity index is 95 or more.
The machine oil 3 that first polyol ester of mentioned component is mixed to form with the second polyol ester is with refrigerant with lower
Solubility, therefore the refrigerating capacity of refrigerating plant requirement can be reached in compressor 100 with less refrigerant.
The machine oil 3 for compressor according to embodiments of the present invention, by using the first polyol ester and more than second yuan
The mixing of alcohol ester according to a certain percentage is moistened thereby using there is lower solubility between the machine oil 3 and refrigerant of compressor
Slip is preferable, therefore, is fully cooled even if can also be realized when refrigeration dosage is relatively low.
In some embodiments, further include for the machine oil of compressor 3：Squeeze antiwear additive, antioxidant, sour agent for capturing, gold
Belong at least one of activating agent, is added in the machine oil 3 for compressor and squeezes antiwear additive, antioxidant, sour agent for capturing, metal
It is one or more in activating agent, there can be better performance thereby using the machine oil 3 in compressor.
In some embodiments, further include squeezing antiwear additive for the machine oil of compressor 3, addition, which squeezes, in machine oil 3 resists
Grinding agent can improve the lubricating ability of machine oil 3 under heavy loading, reduce the friction coefficient between movement component, improve the wear-resistant of component
Damage ability reduces component abrasion, improves the projected life of compressor 100, squeezes antiwear additive at least from molecular formula c or molecular formula d
One is selected in the group that the alkyl polyoxyalkylene phosphate of representative is formed, molecular formula c and molecular formula d are as follows：
Wherein, R4 is an alkyl with 1~8 carbon atom, and R5 is H or alkane with 1~3 carbon atom
