Description
Technical field
The utility model relates to the delivery temperature regulation structure of a kind of compressor, particularly a kind of compressor.
Background technique
In the refrigeration system, compressor is as heart component, and its reliability, working life are very important concerning whole system.In the compressor operating process, its delivery temperature is higher or on the low side all can to exert an influence to the reliability of compressor.The delivery temperature height of compressor, electrical machinery life can be affected, and also burns easily.Lubricated oil properties also can be affected, and occurs degradation bad phenomenon under charing, the viscosity easily.In addition, also occur other phenomenons such as metal sintering between relative movement part easily, these factors all can produce adverse influence to compressor; Because of refrigerant and lubricant oil dissolve each other, delivery temperature is low, can cause in the housing lubricating oil temperature low, and the temperature of lubricant oil is low, and the high-pressure gaseous refrigerant after the compression just is condensed into liquid refrigerants easily, and lubricant oil is diluted, and viscosity descends.Lubricating oil viscosity descends, and the abrasion aggravation causes compressor to shorten working life between moving element.So delivery temperature is higher on the low side all unfavorable to compressor, and some refrigerants are because of the reason of character own, under some operating conditions, delivery temperature is higher or on the low side, such as the R32 cold medium compressor, some operating conditions delivery temperature is very high, the R290 cold medium compressor, and then some operating mode refrigerant delivery temperature is on the low side.
The delivery temperature of compressor is relevant with isentropic exponent with evaporating pressure, condensing pressure, suction superheat and compression process.At with a kind of refrigerant, when evaporating pressure, suction superheat one timing, the compression process isentropic exponent is a certain value just also, if condensing temperature raises, the delivery temperature of compressor rises, otherwise, then descend; When condensing pressure one timing, the degree of superheat is consistent, and evaporating pressure changes, and delivery temperature also can change, and the concrete situation of change of delivery temperature is then relevant with refrigerant saturated humidity line; When condensing pressure and evaporating pressure one timing, suction superheat is big more, and then delivery temperature is big more, otherwise, then more little.
After the pressure range of compressor operating is determined,, can realize by the suction superheat that changes compressor in order to change the delivery temperature of compressor.But the air-conditioning system that can not regulate and control throttling, reduce the suction superheat of the high operating mode of delivery temperature, the suction superheat of other operating modes also can reduce or even not have the degree of superheat, in this case, not only cause the refrigerating efficiency of compressor to descend, also make compressor that liquid hit phenomenon takes place easily.As a same reason, at delivery temperature refrigerant on the low side, improve other suction superheat, cause, the air-breathing quality of compressor descends, and refrigerant circulation descends, and causes the refrigerating capacity of compressor to descend, and also is very disadvantageous.Therefore, be necessary to be further improved and perfect.
