Due to the early purchase, the refrigeration unit has been outdated, and all the relays and contactors have been used for many years. The performance is aging, and often malfunctions, causing downtime, which causes the abnormal temperature and humidity of the production plant to exceed the standard. The mechanical part of the chiller has a large impact, which often causes damage to the chiller impeller, bearings, seals, pump shafts and bearings. The refrigeration unit adopts dozens of relays to control. When the outdoor temperature and humidity fluctuate greatly during the transitional season, in order to ensure the temperature and humidity of the production plant is stable, the chiller starts and stops frequently, sometimes even during the day and at night, causing the relay to move frequently. Relays are often damaged, increasing the cost of equipment maintenance. In order to ensure that the chilled water temperature meets the requirements of the workshop temperature and humidity control, it is necessary to control the amount of steam entering the refrigeration compressor. The vane at the inlet of the compressor impeller is often manually adjusted to regulate the cooling capacity, which will cause the entire grid to be supplied. Unstable, and even caused excessive power grid voltage fluctuations and power outages. The technical transformation plan is proposed. After the inverter is used to start the refrigeration unit smoothly and steplessly, the inverter can be automatically or manually removed, and then connected to two 45kw cooling water pumps. After the inverter is started smoothly, the automatic speed regulation and stable water pressure are adopted. In order to achieve energy saving purposes.
