摘要
直流式整流罩空调在夏季高温、高湿、高盐雾环境中,存在制冷量有台阶、热工影响因素多、受环境影响大、响应特性差等问题,对此展开分析,提出了比例积分微分(Proportion-al Integral Derivative,PID)控制、温湿度解耦、制冷量台阶处理等空调控制策略,并对其进行试验验证,结果表明该措施有效.采用该控制策略对航天器进行环境保障,满足航天器对火箭整流罩内的温湿度要求.
Abstract
An analysis is conducted on the problems of step cooling capacity,multiple thermal in-fluencing factors,significant environmental impact,and poor response characteristics of the DC fairing air conditioning system,facing high temperature,high humidity,and high salt mist envi-ronments in summer.Based on this analysis,the air conditioning control strategies such as pro-portional integral derivative(PID)control,temperature and humidity decoupling,step cooling ca-pacity treatment are proposed.Experimental verification is conducted on the control strategy,and the results showed that this measure was effective and feasible.It can effectively alleviate the step problem of air conditioning cooling capacity.The control strategy has been adopted to provide en-vironmental protection for spacecraft,meeting the temperature and humidity requirements of the spacecraft for the rocket fairing.
