空调故障?关键在过滤器和干燥过滤器,师傅曝隐情!

新闻来源:杭州日丰空气处理设备有限公司    发布日期:2018.01.05

如果空调管路系统中有杂质,这些杂质进入到空调系统中,就会引起空调电子膨胀阀故障、甚至因堵塞导致压缩机回油不良,烧毁压缩机,最后导致整个空调系统故障。一个师傅这让跟我说。
If there are impurities in the air conditioning pipeline system, these impurities enter the air conditioning system, which will cause the failure of the electronic expansion valve of the air conditioner, or even lead to the bad oil return of the compressor due to the blockage, and destroy the compressor, and finally lead to the failure of the whole air conditioning system. A master to tell me.
 
那怎么才能保证空调系统的纯净,这里我们就不得不用到过滤器与干燥过滤器,今天我们来对过滤器与干燥过滤器这个部件的原理、应用、安装等内容进行介绍,希望对大家有所帮助。
Then how can we ensure the purity of the air conditioning system? Here we have to use filters and drying filters. Today we introduce the principles and applications of filters and dry filters, and hope to be helpful for you.
 
1. Filter:
 
过滤器是空调管路系统中过滤杂质的部件。其安装位置主要在机组电子膨胀阀或毛细管的前后两侧,目的是为了防止系统中的杂质堵塞电子膨胀阀,导致电子膨胀阀故障。
The filter is a component that filters the impurities in the air conditioning system. The installation position is mainly on the front and back sides of the electronic expansion valve or capillary tube of the unit. The purpose is to prevent the impurities in the system from blocking the electronic expansion valve, resulting in the failure of the electronic expansion valve.
 
系统中的杂质主要是指在安装过程中,管路焊接时充氮不规范导致的氧化皮或一些其他的固态杂质,也有压缩机因长期使用,不可避免的一些机械磨损带来的金属粉末。
The impurities in the system mainly refer to oxide scale or some other solid impurities caused by nitrogen charging during pipeline installation, and also some metal powders that are unavoidable due to mechanical wear due to long-term use.
 
当系统中杂质较少时,过滤器能够有效的起到过滤保护作用,但是如果系统氧化皮太多(比如焊接不充氮气),这些杂质反而会把过滤器完全堵死,导致系统故障,甚至因堵塞导致压缩机回油不良,烧毁压缩机。
二、干燥过滤器:
Two. Dry filter:
 
干燥过滤器用于吸收系统中的水分,滤除系统中的杂质,防止制冷系统管路发生冰堵和脏堵。
The drying filter is used to absorb the water in the system and filter out the impurities in the system, so as to prevent the freezing and dirty plugging of the piping of the refrigeration system.
 
由于系统最容易堵塞的部位是室内机电子膨胀阀和毛细管,此干燥过滤器通常安装在冷凝器与节流装置之间。
Since the most blocked parts of the system are the indoor electronic expansion valve and capillary, the drying filter is usually installed between the condenser and the throttle.
 
干燥过滤器其外壳采用紫铜管收口成型,内装金属细丝或多孔金属板,可以有效地过滤杂质。干燥过滤器中采用分子筛作为干燥剂,以吸收制冷剂中的水分。当干燥剂因吸水过多或被杂质堵塞严重时,应进行更换。
The shell is made of copper drying filter installed in the closing molding, metal wire or porous metal plate, can effectively filter the impurities. Molecular sieve is used as a desiccant in the drying filter to absorb the moisture in the refrigerant. When the desiccant is overabsorbed or blocked by impurities, the desiccant should be replaced.
