Research on intelligent control strategy for air conditioning temperature of Guangzhou metro trains
Influenced by the climate,the air conditioning comfort of Guangzhou metro trains has become the primary concern of passengers,which is directly related to the evaluation of the overall comfort of the train.This article takes the target temperature,fresh air valve opening and compressor start control logic of the air-conditioned passenger compartment of Guangzhou metro line 21 trains as the research object.Based on the accumulation of preliminary application data of Guangzhou metro line 21,the application effect of the existing air conditioning control strategy for train air conditioning on line 21 is comprehensively analyzed.In view of the increasing demand of passengers for differentiation between warm and cold carriages,this article further carries out the research on air conditioning intelligent control strategy and puts forward three optimization measures,including the implementation of automatic time and regionally differentiated target temperature adjustment strategy,optimization of fresh air valve opening control in winter,and improvement of compressor start-up control logic.After tracking and verification,it has been confirmed that the intelligent control strategy for air conditioning can effectively improve the comfort of the carriage and reduce air conditioning energy consumption.
