\t\t\t\t\t\tDue to the improper operation of\u00a0low temperature\u00a0chiller system, there is the possibility of \u00a0water\u00a0entering\u00a0into\u00a0refrigerant system. Therefore, in view of the problem of water supply in low temperature\u00a0chiller system, process guidance is formulated to serve as a reference for maintenance.
\n1. Analyse\u00a0the reasons. \tCheck the whole\u00a0low temperature\u00a0chiller system to confirm the cause of freezing damage and find out the leak point.
\n2. Blow dirt in sections.
\n(1) First, air compressor can be used to blow water (save nitrogen), until no water mist precipitate. Then blow with high pressure nitrogen, at the same time, heat the nitrogen (the nitrogen cylinder is prohibited from heating).
\n(2) Because the pipeline of <\/strong>baixo<\/strong> temperature\u00a0chiller system<\/strong><\/a> is complex, water can be blown out in segments by using welding torch in some parts according to specific conditions.
\n(3) Heat\u00a0and dry. The capillary, thermal expansion valve, compressor and other small components can be placed in the oven to bake and dry. Do\u00a0replace the refrigerating oil\u00a0in the compressor after the water is dried.
\n1. Vacuum drying
\n(1) Restore\u00a0the pipeline\u00a0and\u00a0maintain\u00a0the nitrogen pressure to ensure the air tightness of the system.\u00a0Then connect\u00a0the vacuum pump to the system\u00a0for vacuum drying. (Dry filter barrel should be added to the front end of vacuum pump to avoid excessive water and gas entering the vacuum pump)
\n(2) In the process of vacuum drying, heat the place where water is easily stored in the pipeline, and the time can be determined according to the site.
\n2. Debugging\u00a0and running.
\n(1) Make sure that the water in the system is basically removed.
\n(2) Connect the external drying filter barrel to the system and replace the desiccant after running for 5 minutes. At the same time, observe the operating parameters of the unit and pay attention to the sound of the compressor. If the dry filter is cold, the expansion valve frosts, and there is a pressure difference of more than 0.5 kg before and after the return air filter, stop\u00a0the compressor \u00a0\u00a0immediately.
\n3. Completion of maintenance
\n(1) Remove the refrigerant pipe from the drying filter barrel and restore it.
\n(2) Check the supplementary refrigerant quantity. Turn on and check the machine running parameters to confirm normal. <\/p>","protected":false},"excerpt":{"rendered":"
