摘　　要：为加强集中式的一次回风中央空调系统设备状态的监控,设计以中央空调设备为研究对象,利用上位机组态软件将中央空调一次回风空气的温度、湿度等参数进行监测和控制,同时采用DDC控制器作为下位机对中央空调一次回风空气质量进行控制。在不同季节通过上位机组态进行相应的PID参数设置,可以较好地解决了夏、冬不同季节空气调节质量与效率之间的矛盾。To strengthen the centralized a return air central air-conditioning system equipment state monitoring and design central air conditioning equipment as the research object using PC configuration software in monitoring and control of the central air-conditioning system with primary return air air temperature, humidity, and other parameters, at the same time, the DDC controller as lower computer to control the central air-conditioning system with primary return air air quality. In different seasons, the PID parameters are set up by the host computer configuration, which can solve the contradiction between the quality and the efficiency of the air conditioning in summer and winter.
