Method for optimizing control parameters of ventilation and air conditioning system of subway station

Abstract

The invention provides a method for optimizing control parameters of a ventilation and air conditioning system of a subway station and belongs to the field of heating ventilating and air conditioning. The method is applied to the ventilation and air conditioning system and mainly comprises the following steps: building a simulated model of a platform layer of the subway station according to a design drawing of the subway station, and determining the parameters of the simulated model; meshing the simulated model; calculating initial control parameters, and programming a PID (Proportion Integration Differentiation) control program of the ventilation and air conditioning system of the subway station by using Fluent UDF (Universal Disk Format); operating Fluent software, and calculating and solving the simulated model of the ventilation and air conditioning system of the subway station; comparing simulation temperature and speed control results of a flow field under different control parameters, and finally optimizing to obtain optimal control parameters. The method disclosed by the invention has the characteristics of changing the control parameters of the ventilation and air conditioning system of the subway station, calculating the simulation temperature and the speed control results of the flow field under different control parameters by using the Fluent software and obtaining the optimal control parameters by comparison and optimization.

Description

technical field [0001] The invention relates to the field of heating, ventilation and air conditioning, and proposes a control parameter optimization method for the ventilation and air conditioning systems of subway stations. Specifically, the Fluent software is used to analyze and solve the flow field of the ventilation and air-conditioning system of the subway station, and the control parameters of the ventilation and air-conditioning system of the subway station are optimized through the flow field analysis results. Background technique [0002] With the development of the subway, the subway lines are getting longer and longer. Although the subway can bring convenience to the people, the long-term occupation of the road during the construction period will also cause great pressure on the road traffic and inconvenience to pedestrians. How to shorten the construction period of subways and subway stations and reduce the congestion on the ground during construction is an impo...

AI Technical Summary

Problems solved by technology

This method is simple and effective, but it consumes a lot of time and manpower, and the equipment operation cost is high, and the operation is highly professional

In addition, the above method is limited to setting the control parameters of the ventilation and air conditioning after the construction of the subway station is completed.
