Description
Technical field
This utility model relates to air-conditioning technical field, in particular to a kind of air conditioning system。
Background technology
At present, in technical field of air conditioner refrigeration, it is used mostly R410a cold-producing medium to substitute R22 cold-producing medium, it is with the obvious advantage is embodied on convertible frequency air-conditioner, but it is owing to the GWP (GlobalWarmingPotential, global warming potential) of R410a cold-producing medium is higher, day by day serious at Present Global greenhouse effect, under the background of countries in the world reply global climate transition pay attention to day by day, it will eliminated gradually。Therefore, the low GWP cold-producing medium that more absorbed research at present is representative with R32 cold-producing medium, R290 cold-producing medium, especially for this cold-producing medium almost not having any pollution of R290 cold-producing medium, simultaneously, the research and development of corresponding compressor are also underway, particularly the lubricating oil research and development of new type compressor, are increasingly subject to pay attention to。
The properly functioning of system is extremely important by the lubricating oil in cooler compressor, and lubricating oil plays a part cylinder and rotor lubrication, sealing and cooling。When compressor runs well, lubricating oil sucks cylinder by bent axle bottom compressor, system is entered with the cold-producing medium of High Temperature High Pressure after overcompression, afterwards along with refrigerant cycle turns again to bottom compressor, the heat that compressor electric motor and cylinder produce simultaneously also can be taken away by cold-producing medium and lubricating oil。If owing to some reason causes that oil return return-air is not smooth, will result in the problem such as compressor lubrication shortage of oil, motor idle running heating, will cause that between compresser cylinder and rotor, abrasion strengthens, internal temperature is too high further, ultimately result in burn-down of electric motor, system crash。So when system designs, must ensure that lubricating oil can normally return compressor and motor heat is discharged timely。
But, for combustible refrigerant R290 cold-producing medium, its viscosity can sharply increase at low temperatures, particularly in changes in temperature frequency changer, when defrosting terminates cross valve commutation, super low temperature refrigeration agent and lubricating oil in vaporizer (indoor heat exchanger) require over throttling arrangement (such as, electric expansion valve) enter condenser (outdoor heat exchanger), simultaneously combustible refrigerant because of security consideration charging amount less, therefore the pressure ratio R410a cold-producing medium of air conditioning system, the pressure of the air conditioning system of R32 cold-producing medium is little a lot, thus the oil that viscosity can be caused relatively larger blocks throttling arrangement, cause that combustible refrigerant cannot participate in circulation, and then make compressor dally, ability and operation power drop, system oil starvation lacks fluorine, the motor excessive heating of compressor after long time running, greatly reduce the service life of compressor and system, the use sense affecting user is subject to, the appearance of this problem simultaneously also uses the air conditioning system of combustible refrigerant to cause very big impact for design。
Therefore, how when air conditioning system occurs oil stifled, solving the stifled problem of oil timely and effectively makes air conditioning system recover to run well, and then avoid air conditioning system that the phenomenon that ability decays occurs because oil blocks up, to ensure the service life of compressor and air conditioning system, improve the comfort of air conditioning system simultaneously, become technical problem urgently to be resolved hurrily。
