Abstract

Now many cities and towns have a lot of large shopping malls, shopping malls have a large flow of people, fire prevention and air have high requirements. Not only should there be a good ventilation system to ensure a comfortable environment, but also to consider the needs of fire exhaust and smoke. At present, large and medium-sized shopping malls and underground parking lots are all equipped with blast and air supply systems, which not only bring people a comfortable shopping and leisure environment, but also consume a lot of electricity and energy. The use of PLC control technology and variable-frequency drive speed regulation technology, the transformation of the traditional shopping mall exhaust system, according to the flow of people in the shopping mall to adjust the speed of the wind unit, to achieve multi-stage speed regulation, and can realize the conversion of power frequency switch, and can significantly reduce the consumption of electric energy, to achieve the effect of energy saving.
