Analysis of Fan Energy Saving Controller

Analysis of Fan Energy Saving Controller The purpose of the energy-saving control and management of the fan is put forward, which is to realize the closed-loop automatic control of the fan operation. The temperature of the water supply is preset according to the needs of production. The influence of the climate and meteorological environment on the water temperature and the influence of the change of the system heat exchange conditions on the water temperature are reflected in time by the measured value of the temperature sensor, and finally the energy consumption of the cooling equipment is adjusted to reduce the temperature. Stabilize the water supply temperature and realize self-control and energy saving.Vacuum Brazing of EGR Stainless Steel Cooler It is generally believed that "frequency conversion technology" is an ideal method to complete the above process. However, the application of frequency conversion speed regulation technology in the fan control of circulating water cooling tower has the following limitations and defects:Aluminum alloy vacuum brazing of heat exchangers ①"Frequency control technology" can achieve high temperature control accuracy, but this is not very important in the circulating cooling water system.What are the applications of vacuum brazing of aluminum alloy? ② ②The energy loss of the inverter itself (the average operating efficiency is less than 90%) affects the energy saving effect. ③The variable speed operation causes the angle of attack of the fan blades to change (wind angle), and the fan runs away from the working point, which reduces the efficiency.
