Description
Technical field
The utility model is related 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 have to environmental protection characteristic (ODP=0, low GWP) for cold-producing medium, secondly alternative refrigerant physical property will as far as possible with original refrigeration
Agent is close to, and reduces alternative cost.
Belong to HFC class cold-producing mediums using R134a cold-producing mediums at present, although its ODP is zero, and single GWP is higher, is 1430, is
《The Kyoto Protocol》In restriction cold-producing medium, 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 cold-producing mediums, i.e. hydrogen-fluoro-olefin, with good environmental protection characteristic, while the thing of its hot physical property and R134a
Property closely, can be with " directly substitute ", but R1234yf Costco Wholesales are too high, it is very uneconomical.
In consideration of it, Honeywell develops R1234ze on the basis of R1234yf, and (ODP=0, GWP=1, A2L class is freezed
Agent), R1234ze falls within HFO class cold-producing mediums, is used as foaming agent, finds to can also serve as cold-producing medium 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's
75%, while suction draught head is also about the 76% of R134a, but the suction and discharge pressure ratio of R1234ze compressors is close to R134a.
Additionally, the theoretical delivery temperature (78.3 DEG C) of R1234ze is also low than R134a, about the 92% of R134a.
Used as compressor with rolling rotor, because compression cavity temperature is higher, the rolling piston and blade in cylinder can occur
Thermal deformation, height (axial direction) can increase.So, the upper and lower ends face of rolling piston and blade is possible to right with metal (upper
Answer end face to come in contact, so as to wear and tear, 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 is 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 process is compressed to refrigerant R134a, generally comprises compressor machine
Body, is provided with cylinder and motor in body, its cylinder and piston, blade height gap it is larger, piston, blade upper and lower ends face
It is poor with the sealing effectiveness between the major and minor bearing of cylinder upper and lower ends, then by 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.
Utility model content
R1234ze is little 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 less than R134a, therefore can reduce existing
There are compresser cylinder and piston, interlobate height gap, less leakage improves compressor efficiency.
Low compared with R134a compressors by 8% or so in view of the compression chamber temperature of R1234ze compressors, only 78.3 DEG C, heat is swollen
Bulging deformation is less than R134a, therefore, the difference in height of the cylinder of R134a compressors and the difference in height of rolling piston, cylinder and blade,
Can be less with the difference in height of the difference in height of rolling piston, cylinder and blade than cylinder in R134a compressor respectively.
And reducing difference in height (height gap), the sealing effectiveness between rolling piston, blade and upper and lower bearing can improve, then
Also therefore reduced by the refrigerant gas leakage between rolling piston, blade upper and lower ends face and bearing.
In view of problems of the prior art, the purpose of this utility model is to provide a kind of closed type rolling rotor compression
Machine, by the height gap for reducing cylinder and the height gap, cylinder and blade of rolling piston, it is possible to increase the energy of compressor
Power, reaches the effect for improving compressor efficiency, and simple and reasonable, energy-conserving and environment-protective, efficiency height, good sealing effect.
