Device.Such air-conditioning be it is a kind of by using kind of refrigeration cycle come cool down or heat interior device, the kind of refrigeration cycle include compression
Machine, outdoor heat converter, expansion valve and indoor heat converter.That is, air-conditioning can include the cooler for making indoor cooling
With the heater for making heating indoor.And air-conditioning can also include a kind of air conditioner for both for making heating indoor or cooling.As sky
The compressor of the part of tune is a kind of device of compression refrigerant.During compressor operation, crankshaft eccentric portion drives dynamic vortex dish axle
Cervical part of esophagus is moved.
Swirl type cold compressor is a kind of new positive displacement compressor that the eighties in 20th century just grows up, and it is with which
Efficiency high, small volume, light weight, noise are low, simple structure and the features such as smooth running, are widely used in air-conditioning and refrigeration machine
In group.Screw compressor mainly includes following parts：Orbiter, fixed scroll, cross slip-ring, upper bracket, sealing device,
Housing unit, crankshaft group, lower carriage component, are a kind of low noise, efficient compressor, are being widely used in air-conditioning equipment
Field.Scroll compressor uses such method：Multiple discharge chambes are formed between the whirlpool disk of two rotations reversely with each other, and
And these discharge chambes constantly move to reduce their volume to center, meanwhile, constantly it is inhaled into, compresses and discharges refrigeration
Agent gas.
At present, there is many places directly contact in the pump assembly of screw compressor：The vortex ring of orbiter and fixed scroll
Vortex ring, the sealing surface of the sealing surface of orbiter and fixed scroll, cross slip-ring key side and orbiter key slot side, cross
Slip ring key side and upper bracket key slot side, cross slip-ring end face and orbiter real estate, cross slip-ring end face and upper bracket
Datum level.At present, a kind of lubrication strategies for adopting at above-mentioned six are：The micro lubricating oil that carries during by air-breathing or in the pump housing zero
Oil passage realization is opened up on part, it cannot be guaranteed that a few place's wear surfaces, the sealing surface of particularly dynamic and static scroll plate is obtained this scheme
Lubricate well.Another scheme realizes appropriateization of fuel feeding often by setting restricting element or variable cross-section path, but
This kind of method can increase processing and the difficulty assembled, it is also difficult to ensure the reliability of whole machine.
To improve the performance of kind of refrigeration cycle, it is possible to use gas injection is circulated.The method is by gaseous state system using an injection orifice
Cryogen is expelled in discharge chambe.The gaseous refrigerant with the pressure between the cold-producing medium for being inhaled into scroll compressor with arranged
Middle duty pressure between the pressure of the cold-producing medium for going out scroll compressor.Therefore, because a small amount of gaseous refrigerant is injected into
In discharge chambe, the time that injection orifice is opened is short and limit the reduction of injection efficiency.Still an alternative is that in scroll compressor
Multiple injection canals are inserted in machine and gaseous refrigerant is fed in multiple discharge chambes by every circuit.
Air-conditioner used in household room and working environment, its compressor are divided into rotor compressor and screw compressor
Two kinds, rotor compressor is high in the compression efficiency of low-pressure ratio, and screw compressor is high in the compression efficiency of high-pressure ratio.Air-conditioning makes
Used time, compressor Jing often operate under high-low pressure ratio, and single form compressor in differential pressure change is leaked and can be increased, and makes compression
Engine efficiency is reduced, and affects compressor reliability.On the other hand, using the single form compressor of second vapor injection, compression is indoor straight
Jet is connect, refrigerant gas losses by mixture during jet, can be produced, affect compressor efficiency.Single form compressor is in ultralow temperature ring
Under border, heating capacity decay is very serious, and Energy Efficiency Ratio is very low.
