To air - condition temperature control system , in this paper , firstly , the mathematical model is established by using the differential equations method . though equations deducing to find the control object , which is the relationship between the rooms " temperature - time constants and control system ' s kinds of performance indexes , elucidate the effects of the big rooms " temperature - time constans to the control system . then combined with the requirements of air - condition craft to the control , it is proposed that the main question needed to be solved under the air - condition control system designing is its quickness
本文首先针对空调温度控制系统，建立数学模型，采用微分方程法，通过公式推导，找出空调控制对象? ?房间温度时间常数与系统各项性能指标的关系，阐明房间温度时间常数大对控制系统的影响，再结合空调工艺对控制的要求，提出了对空调控制系统的设计应主要解决其快速性问题。
