Original title: Use and installation of drying filter The dry filter is one of the most commonly used accessories in the refrigerant pipeline. It is mainly used to clean the harmful substances in the system, so re of refrigerant and lubricating oil can dissolve copper and bring it to the compressor to form a copper film on its metal surface, thus affecting the operation of the compressor. 4. Refrigerant oil: When the temperature is low to a certain temperature, the refrigerant oil will precipitate stone toad, and the POE oil used for environmental protection refrigerant has strong hygroscopicity, so it is easier to hydrolyze acidic characteristics. Expand the full text The existence of the above substances will seriously threaten or destroy the performance of the moving parts in the system and the cylinders and refrigeration systems that need compressed gas, so they should be affin, but because the refrigerant oil will precipitate paraffin only when the temperature is below -35 degrees, it is not needed in the system operating at medium and high temperatures. The use of dry filter is divided into: Filtration capacity: Filters the system of harmful substances, thus protecting important components such as expansion valves and compressors. Moisture absorption capacity: For refrigeration products produced according to the standard process, nutsche filter dryer ,wiped film distillation, it is difficult to determine how much moisture absorption capacity of the dryer needs to be used, so the general dry filter production is nominal according to the requirements of the standard. Ability to adsorb acid and ester substances: Expermage rying filter also has an important function of cleaning the system after the compressor is burned out.
