Abstract
A2 refrigerant mainly containing a carbon-carbon double bond-containing hydrofluoroolefin has a function to suppress abrasive wear, compared to conventional HFC-based refrigerants, because the hydrofluoroolefin generates iron fluoride especially on the surface of the vane and piston, where sliding force is severe, from hydrogen fluoride, even if it is generated in reaction with water and oxygen. It is possible to reduce abrasive wear, by using a refrigerant containing as the base component a hydrofluoroolefin as operating refrigerant and a refrigeration oil 3 miscible with the refrigerant and a vane 10 made of a high-speed tool steel and sintered and quenched, because hydrogen fluoride generated by decomposition of the refrigerant in the region of a vane tip region 10a and a piston 9 peripheral surface, where sliding force is severe is converted to iron fluoride. It is also possible to obtain a hardened structure containing carbides of W, Mo, Cr and V dispersed in a fine martensite matrix and produces the rotary compressor more cost-effectively by quenching and sintering the vane 10.

Below, will still should be understood that the present invention does not receive these embodiments' restriction with reference to description of drawings the preferred embodiments of the present invention.
Fig. 1 is the longitudinal section that the rotary compressor in the embodiments of the invention 1 is shown.As shown in fig. 1, the stator 2a of motor 2 is fixed in the upper area of seal container 1, and the compression mechanical part 5 with the axle 4 that is driven by rotor 2b is fixed in the lower area of seal container 1.For example, use bolt that main bearing 7 is fixed to the end face of the cylinder 6 of compression mechanical part 5, and supplementary bearing 8 is fixed to the bottom surface of cylinder 6.In cylinder 6, piston 9 is placed among the eccentric region 4a of axle 4, so that axle carries out the off-centre rotation.
In addition; Be stored in the bottom section of seal container 1 be can with the HF hydrocarbon that contains the carbon-carbon double key (for example; HFO1234yf) dissolve the refrigerator oil 3 of the polyvinylether that does not contain EP agent, polyol ester or the PAG that mix as the refrigeration agent of solvent (below, be called refrigeration agent R).
Fig. 2 is the cross-sectional view that illustrates according to the compression mechanical part in the rotary compressor of the present invention 5.As shown in Figure 2, blade 10 inserts among the blade groove 6a of cylinders 6, and leaf spring 11 is placed on the back side 10b of blade 10, makes the tip region 10a of blade 10 be forced into the outer circumferential face of piston 9 and contacts.The material of blade 10 is processed by the SKH Rapid Tool Steel and by nitrogenize, is perhaps processed and be sintered and quenched by the sintered alloy steel of for example Rapid Tool Steel.
Below explanation is had the operation and the effect of the rotary compressor of above structure.At first, through being formed at the suction port 12 in the cylinder 6, the refrigerant gas of refrigeration agent R is sucked in the suction chamber 13.Refrigerant gas in pressing chamber 14 is compressed through the left-handed rotation (direction of arrow) of piston 9, and is expelled in the seal container 1 from the exhaust port (not shown) through discharging otch 15.Be expelled to the refrigerating machine mist of oil that the compression refrigerant gas in the seal container 1 exists in container, be transported, and discharge through the discharge tube 16 that is positioned at seal container 1 top through the space around the motor 2.
Because apply with pressure and high head pressure from leaf spring 11; So through the back side 10b of blade 10 being applied sizable power with the pressure reduction of inner pressure of air cylinder; Therefore the tip region 10a of blade 10 and the outer circumferential face of piston 9 are in contact with one another under the boundary friction state, and are under the rugged environment of high temperature.Therefore, wherein refrigeration agent R is decomposed and produces hydrogen fluoride etc.
According to the present invention; In order to ensure the blade 10 and the reliability of piston 9 that are positioned under such rugged environment; The material of blade 10 is processed by the SKH Rapid Tool Steel and is processed and by being quenched by nitrogenize or by sintered alloy steel; Its iron component under the state of exposing surface with the hydrogen fluoride reaction that decomposition produced of refrigeration agent R, thereby in the vane tip zone outer circumferential face formation ferric flouride of the surface of 10a and piston 9.Therefore can reduce slip resistance and abrasive wear, and guarantee the for example reliability of the slide member of blade 10.In addition, the sintering of sintering blade and Quenching Treatment provide the sclerotic tissue of the carbide that contains the W, Mo, Cr and the V that are dispersed in the trickle martensitic matrix, and have reduced cost of production.
Because refrigerator oil does not contain EP agent, so can also suppress the decomposition of refrigeration agent itself.Because polyvinylether, polyol ester or PAG can be used as refrigerator oil with the miscible refrigerator oil of refrigeration agent R; So distribution and circuit refrigerator oil can be recovered in the rotary compressor in refrigeration cycle, therefore guarantee the high reliability of rotary compressor.
Although be used as the agglomerated material of blade 10, yet can be used to practice thrift more the production of cost like other sintered alloy steels of alloy tool steel (SKD) and stainless steel (SUS) at present embodiment 1 high speed tool steel (SKH).As everyone knows, the sintering of sintered alloy steel and Quenching Treatment and additional anneal are handled the further raising that causes toughness.
The slider of rolling piston type rotary compressor has been described; Be blade 10 and piston 9; But the present invention also is applicable to other rotary compressors of sliding-vane compressor for example, the scrollwork of scroll compressor similarly; And for example axle and other sliders of bearing, so that the slip resistance when reducing to use refrigeration agent R and improve reliability and cost benefit.
Although the driving mechanism of motor as compression mechanical part is installed in seal container in present embodiment 1, however the embodiment of driving mechanism be not limited thereto, and motor can be installed on the outside or engine of seal container and can be used to operation.
Industrial usability
As stated; Even the HF hydrocarbon that compressor according to the present invention contains the carbon-carbon double key in use is during as the refrigeration agent of solvent; Also can guarantee the reliability of compressor, compressor according to the present invention for example can be used in during water heater uses with compressor etc. with compressor, dehumidifier with compressor, deep freezer with compressor, vehicle air conditioning.
