济南中央空调改造

  中央空调的工作原理是气态制冷工质(如氟利昂)经压缩机压缩成高温高压气体后进入冷凝器,与水(空气)进行等压热交换,变成低温高压液态。液态工质经干燥过滤器去除水份、杂质,进入膨胀阀节流减压,成为低温低压液态工质,在蒸发器内气化。液体气化过程要吸收气化潜热,而且液体压力不同,其饱和温度(沸点)也不同,压力越低,饱和温度越低。

The working principle of central air conditioning is gaseous refrigerating agent (such as freon) after compressor compressed into high temperature and high pressure gas entering the condenser, isobaric heat exchange with water (air), into a low temperature and high pressure liquid. Liquid working medium by the dry filter to remove water, impurities, into the expansion valve throttling decompression, become low temperature low pressure liquid working medium, gasification in the evaporator. To absorb liquid gasification process of latent heat of gasification and liquid pressure is different, the saturation temperature (boiling point) is also different, the lower the pressure, the lower the saturation temperature.

  而室外空气经中央空调处理时,由于大多数粗精效过滤网仅能过滤3um以上的悬浮颗粒物,其微细颗粒物则随风直接进入风道,而风道内表面虽然看似光滑,但其实际粗糙度远远高于微细颗粒物的大小,因此,这些微细的颗粒物随着空气滚动与风道内壁相互碰撞摩擦产生静电吸附越积越多,从而导致风道内壁的粗糙度越来越大,灰尘粘附加速进行,如此长年累月灰尘越积越厚最终形成较厚积尘。

And outdoor air by the central air conditioning treatment, since most coarse fine effect filter to filter only 3 um suspended particulate matter and its fine particulate matter directly into the wind with the wind, though seemingly smooth surface inside the duct, but its actual roughness is much higher than that of the size of the fine particulate matter, therefore, the fine particulate matter with air rolling with air duct wall friction electrostatic adsorption is piling up, leading to air duct wall roughness is more and more big, the dust adhesion accelerating, so long the product the thick dust dust eventually form a who。

  以上内容均根据中央空调节能改造在实际工作中遇到的问题整理而成,仅供阅读、参考,如有问题请及时沟通、指正。

The above content are according to the central air-conditioning energy saving reconstruction problems in the practical work arrangement, only for reading, reference, if there is any question, please timely communication, correct.
