Description
Technical field
The present invention relates to compressor field, and in particular to a kind of closed type rolling rotor compressor.
Background technology
In view of international convention and relevant laws and regulations, refrigerant replacement is current whole refrigeration, the hot issue of air conditioner industry, is replaced
First had to for refrigerant with environmental protection characteristic (ODP=0, low GWP), secondly alternative refrigerant physical property will as far as possible with original refrigeration
Agent approaches, and reduces alternative cost.
Belong to HFC class refrigerants using R134a refrigerants at present, although its ODP is zero, single GWP higher, is 1430, is
《The Kyoto Protocol》In limitation refrigerant, it will be gradually eliminated, it is therefore desirable to seek new alternative refrigerant.For
R134a, Du Pont and Honeywell have developed alterntive refrigerant R1234yf (ODP=0, GWP=7), and R1234yf is forth generation system
Cryogen, belongs to HFO class refrigerants, i.e. hydrogen-fluoro-olefin, has good environmental protection characteristic, while the thing of its hot physical property and R134a
Property it is very close, can " directly substitute ", but R1234yf Costco Wholesales are too high, very uneconomical.
In consideration of it, Honeywell develops R1234ze on the basis of R1234yf, (ODP=0, GWP=1, A2L class are freezed
Agent), R1234ze falls within HFO class refrigerants, is used as foaming agent originally, finds to can also serve as refrigerant now.
R1234ze costs decline to a great extent compared with R1234yf, and only 1/the 10 of R1234yf, but its hot physical property has necessarily with R134a
Difference, at the same conditions (ASHRAE), the operating pressure of R1234ze compressors is lower than R134a, about R134a
75%, while suction draught head is also about the 76% of R134a, but the suction and discharge pressure ratio of R1234ze compressors is approached with R134a.
In addition, the theoretical delivery temperature (78.3 DEG C) of R1234ze is also lower than R134a, is about the 92% of R134a.
As compressor with rolling rotor, because compression cavity temperature is higher, rolling piston and blade in cylinder can occur
Thermal deformation, height (axial direction) can increase.In this way, the upper and lower ends face of rolling piston and blade is possible to pair with metal (upper
Answer end face to be in contact, so as to wear, cause hydraulic performance decline, or even stall.Therefore, (assembling when component is matched
Before), the height of cylinder and rolling piston, and the height of cylinder and blade, it is necessary to there are certain difference (rolling piston and leaf
The axial height of piece is lower than the axial height of cylinder), and reserved the space of rolling piston and blade thermal deformation.
The existing closed type rolling rotor compressor that processing is compressed to refrigerant R134a, generally comprises compressor machine
Body, is provided with cylinder and motor in body, its cylinder and piston, the height gap of blade are larger, piston, blade upper and lower ends face
Sealing effect between the major and minor bearing of cylinder upper and lower ends is poor, then passes through rolling piston, blade upper and lower ends face and main shaft
Hold, the refrigerant gas leakage between supplementary bearing, also therefore increase, reduce compressor efficiency.
The content of the invention
R1234ze is small compared with R134a pressure and operting differential pressure by 25%, and the stress deformation of vane-piston can reduce accordingly,
Lower than R134a in view of the theoretical delivery temperature of R1234ze, thermal expansion deformation is certain to smaller than R134a, therefore can reduce existing
There are compresser cylinder and piston, interlobate height gap, less leakage, improves compressor efficiency.
Specifically, the compression chamber temperature of R1234ze compressors low compared with R134a compressors 8% or so, is only 78.3 DEG C, heat
Dilatancy is smaller than R134a, therefore, the cylinder of the R134a compressors and difference in height of rolling piston, the height of cylinder and blade
Difference, difference in height that can be respectively than the difference in height of cylinder in R134a compressor and rolling piston, cylinder and blade are small.
And reducing difference in height (height gap), the sealing effect between rolling piston, blade and upper and lower bearing can improve, then
By the refrigerant gas leakage between rolling piston, blade upper and lower ends face and bearing also therefore and reduction.
In view of problems of the prior art, the object of the present invention is to provide a kind of closed type rolling rotor compressor,
By reducing the height gap of cylinder and rolling piston, cylinder and the height gap of blade, it is possible to increase the ability of compressor, reaches
To the effect for improving compressor efficiency, and simple and reasonable, energy conservation and environmental protection, efficiency are high, sealing effect is good.
The present invention provides a kind of closed type rolling rotor compressor, including cylinder, bent axle and motor, and work is provided with cylinder
