Technical Field
The invention relates to an engineering construction method, in particular to a low-speed-stabilizing flow-assisting clean air-conditioning high-efficiency air supply and return engineering construction method.

The air conditioning and ventilating system is a combination of a ventilating system and an air conditioning system, and effective measures for improving the indoor air quality are provided in a targeted manner from multiple aspects by analyzing the influence factors of the air conditioning and ventilating system on the indoor air quality.
At present, the common air-conditioning air-feeding and-returning system for the turbulent flow clean room adopts a scheme that a certain number of high-efficiency filters are arranged at the top of the clean room, and the filtered clean air flow emitted from the indoor flow-dispersing cover is mixed with the original air in the clean room, so that pollutants in the original air are diluted. Because the high-efficiency filters on the top of the clean room are distributed in a point mode, indoor airflow distribution is uneven, and although the manufacturing cost and the operating cost of the turbulent flow clean room are low, the turbulent flow clean room is generally only suitable for clean rooms with the cleanliness of ten thousand and more than one hundred thousand due to the inherent defects of the airflow in the clean room. The common air return mode of the turbulent flow clean room is top-conveying side lower wall air return.
In the prior art, a common one-way flow clean room is formed by fully distributing high-efficiency filters along the top of the clean room, so that the whole clean room forms uniformly distributed clean air flow, and most pollutants flow to an air return opening along with the air flow in the shortest path. Thus, a high level of cleanliness can be achieved, typically for cleanrooms with class 100 cleanliness, but the one-way flow cleanrooms suffer from high cost and difficulty in building and maintaining the one-way flow cleanrooms.
