A control parameter optimization method for subway station ventilation and air conditioning system

Abstract

The invention provides a control parameter optimization method of a subway station ventilation and air conditioning system, which belongs to the field of heating, ventilation and air conditioning, and is used for the ventilation and air conditioning system of a subway station. The main steps are: build a simulation model of the platform floor of the subway station according to the design drawings of the subway station, and determine the parameters of the simulation model; mesh the simulation model; calculate the initial control parameters, use Fluent UDF to write the PID control program of the ventilation and air conditioning system of the subway station; run The Fluent software calculates and solves the simulation model of the ventilation and air conditioning system of the subway station; compares the flow field simulation temperature and speed control results under different control parameters, and finally optimizes to obtain the best control parameters. The characteristics of the present invention are as follows: modify the control parameters of the subway station ventilation and air conditioning system, use Fluent software to calculate the flow field simulation temperature and speed control results under different control parameters, and compare and optimize to obtain the best control parameters.

Description

A control parameter optimization method for subway station ventilation and air conditioning system technical field 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 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 s...

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.
