No matter from which point of view, fan energy saving plays an important role in all sectors of the national economy. At present, there are three main measures to be taken in the work of fan energy saving. On the one hand, it is to transform the inefficient old fan, develop efficient series of energy-saving fan, and promote its use in various fields of national economy.
On the other hand, it is necessary to adopt the measures of phase-out for fan with low efficiency and no value of transformation. On the other hand, the intelligent fan economizer is used to retrofit the fan energy-saving. Based on the high-voltage frequency conversion speed regulation, the advanced and accurate modern control system can make the high-voltage motor operate in the optimal economic equivalent, reduce energy consumption and improve the efficiency of the motor.
However, it will take some time to really achieve these points. Take the pipe ventilation equipment commonly used in families as an example, it mainly consists of ventilator, air duct, exhaust outlet, air intake and additional components. Since duct ventilation is a larger system, it is better to install it in the blank room first.
In this way, it can provide the fresh air needed by human body efficiently and evenly, especially the fresh air system with heat exchange, which makes up for the shortcomings of traditional energy-saving houses and creates an energy-saving, sound-proof, clean and comfortable living space. But its shortcoming is that the whole system will be activated when the switch is turned on, and the power consumption is difficult to control.
