First of all, as far as the installation space is concerned, if the heat dissipation needs of large-scale factories are to be met, the central air-conditioning system will certainly not work properly. This number will be very large. The initial investment has made many people unacceptable. From a long-term perspective, the later operating cost of central air conditioning is even astronomical: 2. The installation of traditional fans, blowers and other ventilation equipment is not only complicated, but also has a ventilation effect, and the cooling effect is not ideal.
Among industrial fans, the diameter of large industrial fans can reach 7.3 meters. The affected area mainly depends on the diameter of the fan. The advantages of this type of industrial fan are wide coverage and easy cleaning. In addition, the two problems of noise and high energy consumption can be solved. Under normal circumstances, the output power of an industrial fan is several hundred watts. If it is larger, it is about one kilowatt. If it is used in a factory workshop, because the workshop area is not small, the industrial ceiling fan manufacturer recommends using an industrial fan with a three-phase motor as much as possible, the fan is about 1 kilowatt. Because its utilization effect is better than single phase.
Since ceiling fans are usually used in workshops, operators are usually deployed by frontline workers. The ceiling fan is operated by a frequency converter to achieve start-up, speed control and stop procedures. Therefore, all manufacturers in the industry have done this, and strict requirements apply to the shutdown process. For many customers, especially when employees are not working, a large part of this is achieved by directly turning off the main power supply. Such a power failure corresponds to sudden braking of the ceiling fan. Emergency power failures of large ceiling fans are also important. A large moment of inertia will seriously damage the engine bearing gears. In severe cases, the fan blades will be broken, causing accidental injury to personnel and seriously affecting the service life of the ceiling fan.
