Ventilating system utilizing technology exhausted wind

Abstract

The invention relates to the field of industrial production and discloses a ventilating system utilizing technology exhausted wind. The system comprises a fresh air unit used for conveying treated fresh air to a production room, an exhausting fan used for exhausting technology exhausted wind which cannot be utilized in the production room, and a technology exhausted wind recycling unit used for recycling technology exhausted wind which can be utilized in the production room and conveying the technology exhausted wind into the production room. According to the ventilating system utilizing the technology exhausted wind, the technology exhausted wind is utilized fully, the technology exhausted wind capable of being directly used is conveyed back into the room to be utilized again, the fresh air amount of the room is reduced, the cold heat amount for treating the fresh air is reduced, meanwhile, the capacity of the fresh air unit is reduced, and an energy source is saved.

Description

technical field [0001] This application relates to the field of industrial production, in particular to a ventilation system utilizing process exhaust. Background technique [0002] Integrated circuit production, flat panel display production, optoelectronic devices and other production fields have various process exhaust air due to the needs of process production. Generally, such process exhaust air is directly discharged into the atmosphere. However, a considerable part of the process exhaust air is very clean (or only contains a small amount of dust) general exhaust air. If the process exhaust air is directly discharged through the exhaust fan 2, the cold and heat contained in the exhaust air will not be utilized. It causes waste of energy; at the same time, in order to maintain the parameter requirements of the plant environment, it is necessary to set up a corresponding fresh air unit 1 for this type of exhaust air. Results for unit 1. Such as figure 1 As shown, A is...
