It is restored to liquid, then is gasified again, is looped back and forth like this.This refrigeration system is largely used to the household electrical appliance such as refrigerator, air-conditioning, cold
The business machines such as the industrial equipments such as library, refrigerating chamber and showcase, beverage, ice cream maker.Compressor is above-mentioned compression-type refrigeration system
The heart of system, and refrigerator oil the effects of play lubrication, heat dissipation, sealing and anti-corrosion in compressor is then to compressor and refrigeration
The performance of system plays and there is highly important influence in the service life, therefore the refrigerator oil that selection is had excellent performance is to compression refrigerating system
For be highly important.
As China's environmental problem becomes increasingly conspicuous, protection environment becomes the major issue that all trades and professions are faced.For adopting
For household electric appliances with this compression-type refrigerating system, realize that energy-saving and emission-reduction are a kind of important means that it protects environment.For
Realize the purpose of energy-saving and emission-reduction, those skilled in the art are lower and preferable with refrigerant compatibility often through selection viscosity
Refrigerator oil, to realize antifriction, energy-efficient purpose.
CN 1099454A discloses a kind of hydrocarbonaceous refrigerated machine oil composition, and the composition contains oil based on hydrocarbon-type oil,

Row, protects the purpose of environment.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
Specific embodiment
Detailed description of the preferred embodiments below.It should be understood that described herein specific
Embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
Term " viscosity " each means " kinematic viscosity " in the present invention, and " kinematic viscosity " refers to the dynamic viscosity of fluid and same
At a temperature of the ratio between the fluid density；It is carried out according to national standard GB/T 265-1988 kinematic viscosity measurement method in the present invention
Measurement.Term " viscosity index (VI) " refers to the degree that all fluid viscosities vary with temperature.Viscosity index (VI) is higher, indicates that fluid is viscous
Degree is influenced by temperature smaller, and viscosity temperature is more insensitive；It is according to state label GB/T 1995-1998 in the present invention
Oil product viscosity index (VI) calculation method measures.
As background technology part is introduced, the low viscosity freezing very ideal there are no energy-saving effect currently on the market
Machine oil is for using.Therefore, there is an urgent need to develop the low viscosity refrigerated machine oil composition productions that one kind can further increase fractional energy savings
Product.It is directed to this status, the present inventor has carried out a large amount of research experiment.In primary accidental chance, inventor
It was found that also not viscosity is lower for refrigerator oil, low temperature flow is better, and energy-saving effect is better.In compressor
Certain positions, such as friction pair and piston rod etc., use temperature to be often up to 120 DEG C, as the temperature rises, freezing
The viscosity of machine oil can be lower therewith, and the energy consumption of compressor is not lower not only at this time, and there are also raised trend instead.This phenomenon
Generation may be because with the reduction of refrigerator oil viscosity, friction is secondary and the oil film of piston rod etc. can be thinning, oil film
It is excessively thin that leakproofness is caused to decline, refrigerating efficiency is influenced, refrigerating efficiency is caused not rise anti-drop.In addition, oil film thickness is too low also to be made
Even compressor part dry friction is reduced at boundary lubrication, to cause compressor damage.
