译文：
制冷系统中的各部件在制造厂虽然经过严格的清洗和一定的干燥处理，但在按照管路时特别是焊接时，管内有一部分焊渣和氧化皮粘接在接口周围。另外压缩机运行后也会有一部分金属末，制冷剂本身也含有一定数量的杂质，随着制冷剂在制冷系统内循环变化，它们进入膨胀阀就会堵塞阀孔，进入压缩机就会拉毛和刮伤汽缸。为此，制冷系统中应装有xx这些杂质的设备，这种设备就是过滤网。 过滤器应安装在膨胀阀（毛细管）、电磁阀等自控阀件及压缩机回气管上，安装时应注意过滤器上的流动方向标志，切勿接反。制冷剂从过滤器进口经过滤器流出时，杂质、污物被留在过滤网内。 过滤润滑油的滤网一般用80-100目规格，过滤气态制冷剂一般用70-100目，过滤液态制冷剂可用60目，但膨胀阀和电磁阀前的过滤网需要采用120-200目的细滤网。滤网的材质有不锈钢、磷青铜或黄铜等。 干燥过滤器： 制冷系统中不但有杂质污物，而且还会有水分。水分的来源是多方面的，制冷剂、冷冻油中有水分，系统的管道和设备干燥不严格也残留有潮气和水分。制冷剂（氟里昂）与水不能相互溶解。为了防止冰堵，必须装有干燥器来吸附系统中的水分。在中小型制冷装置上及电冰箱、空调机的制冷系统上，广泛使用装有干燥剂－污物过滤器，具有干燥和过滤功能。 电冰箱和空调机制冷系统中的干燥过滤器为筒式，采用Ф16-18mm铜管，装干燥剂后收口成型，直接与制冷系统的管路焊接。早期采用无水氯化钙、硅胶，现在大多采用吸湿性强的“分子筛”。

原文：
The refrigeration system in all parts of the plant even after rigorous cleaning and drying of some, but in accordance with, especially when the pipe welding, pipe welding slag and oxidized part of the interface around the skin adhesive. In addition there will be a part of compressor running metal end of the refrigerant itself contains a certain amount of impurities, as the refrigerant in the refrigeration system, circulation changes, which will plug into the expansion valve valve hole, into the compressor will nap, and scratching the cylinder. To this end, the refrigeration system shall be fitted with equipment to remove these impurities, the device is a filter. Filters should be installed in the expansion valve (capillary), automatic control valves, solenoid valve and the compressor back to the trachea, the installation of filters should pay attention to the flow direction on the sign, do not take counter. Refrigerant through the filter from the filter inlet flow, the impurities are left in the dirt inside the filter. Filtration of lubricants general use 80-100 mesh filter specifications, filter gaseous refrigerant general use 70-100 mesh, filter the liquid refrigerant can be used 60 mesh, but the expansion valve and solenoid valve before the filters need to adopt the purpose of fine 120-200 filter. Filter materials are stainless steel, phosphor bronze or brass and so on. Dry filter: Impurities in the refrigeration system is not only dirt, but there will be water. There are many sources of water, refrigerant, refrigeration oil has moisture, the system of pipes and equipment are dry and do not strictly have residual moisture and water. Refrigerant (Freon) and the water can not dissolve each other. In order to prevent ice block must be connected to dryer to moisture absorption in the system. In the small refrigeration device and refrigerator, air conditioners, refrigeration systems, with extensive use of desiccants - dirt filter, with a dry and filtering. Refrigerators and air-conditioning system in the dry cooling system for the drum filter using Ф16-18mm copper pipe, installed after the dryer shut forming a direct pipeline welding and refrigeration systems. Early use of anhydrous calcium chloride, silica gel, and now they use a strong moisture absorption, a "molecular sieve."
