An optimal arrangement method for detection points of sudden pollution distribution in centralized air-conditioning air system

Abstract

The invention relates to a method for optimizing the layout of sudden pollution distribution detection points of a central air conditioning duct system. The method comprises the following steps: building a network dynamics model of a central air conditioning duct system; randomly generating a detection point layout position set as an initial population; with minimizing the time for pollutant detection in the network dynamics model as an objective function, optimizing the generated initial population through a genetic algorithm; and taking an optimization result obtained as the layout scheme of sudden pollutant distribution detection points of the central air conditioning duct system. Compared with the prior art, the method has the advantages of optimal layout of detection points, shortest detection time for pollution, and cost saving.

Description

technical field [0001] The invention relates to the design of an emergency monitoring scheme for building sudden pollution, in particular to a method for optimizing the arrangement of detection points for sudden pollution distribution of a centralized air-conditioning system. Background technique [0002] my country's public building area exceeds 5 billion square meters, and more than 500 million square meters are equipped with centralized air-conditioning air systems (using centrally processed air as the medium, transporting it to various areas in the building through air ducts, and then forming an air circulation loop through return air. ), extremely weak in dealing with terrorist biochemical attacks. The pollution of the centralized air-conditioning air system spreads quickly. Generally, the pollutants can be spread throughout the building within a few minutes. It is very easy to be used as a transmission channel for volatile chemical warfare agents such as CWA (Chemical W...

Problems solved by technology

However, in practice, since the detection of pollutants usually requires the application of photoionization rapid detection of VOC technology, the cost of this technology is relatively high, so the number of detection points is limited to a certain extent.

[0005] The current system design for building pollution detection is mainly based on experience or intuition, lacking a reasonable and optimized detection point layout scheme, the detection objective function to be optimized is not clear, and the feasibility of early warning of sudden pollution propagation under experimental conditions has not been studied
