Refrigerator oil is the special lube of refrigeration-type compression set.Be decision and influence refrigeration system refrigerating function and
The important component of effect.Refrigeration compressor obtains low temperature, refrigerator during the work time, by the reduction vaporization of refrigerant
It is oily then the workpiece of refrigerating plant is lubricated.Refrigerator oil plays highly important work in all kinds of refrigeration compressors
With its main function includes the following aspects:Lubricating action, cooling effect and the power as capacity controlling gear.
The common fluid lubricant of refrigerator oil has mineral oil origin, synthesis type, and document CN97122040.9 discloses one kind
Refrigerated machine oil composition, belongs to synthesis type refrigerator oil, is 10~15mm containing viscosity2C5~C18's of the soft wax cracking of/s
Mixedαolefin godied oil.It can also include epoxy compound species stabilizer, phosphate ester based lubricant and phenol type antioxidant etc..
The oil is suitable as the refrigerator oil using fluorine chlorine hydrogen hydrocarbon as refrigerant, it is also possible to makees using fluorochlorohydrocarbon, propane iso-butane or ammonia as system
The refrigerator oil of cryogen.Document CN201010578976.9 discloses a kind of refrigerated machine oil composition, with deep hydrofinishing
Oily based on naphthene base crude oil and/or paraffin base mineral oil, addition accounts for 1.0~2.5% sulfur type, the phosphorous of every gram of basic weight of oil
Or sulphur-phosphorous antiwear additive and account for every gram of basic weight of oil 5~25 μ g silicon type, non-silicon type or compound anti-foaming agent, it is main to use
In the high power compressor of air conditioner that R22 (F-22) is refrigerant.Document CN201010578976.9 discloses one kind
Refrigerated machine oil composition, including following components:1) 10-90wt% F- T synthesis lube base oil;2) 1-10wt% alkylbenzenes
And/or alkylnaphthalene lube base oil;3) 5-85wt% mineral oil and/or poly- a alkene synthetic base oil oil;4) a effective amount of table
Face activating agent;5) a effective amount of additive.The refrigerator oil has good intersolubility with refrigerant containing halogen, is adapted to fluorine hydrogen
Hydrocarbon is the refrigerator oil of refrigerant, can be used for the refrigerator oil of fluorochlorohydrocarbon or low molecule alkane for refrigerant.
