本文以衡阳某办公楼毛细管吊顶辐射加新风空调系统为模拟对象,对该系统启动过程进行研究。通过TRNSYS软件建立计算模型,模拟分析了不同的系统启动模式下,辐射顶板的表面温度、室内空气露点温度及干球温度的动态特性。结果表明:同时开启新风系统和辐射板系统,会发生结露,需提前除湿;辐射顶板的温度下降不是缓慢平稳的,而是快速且具有阶段性;增大供水流量时,对系统预冷时间影响不大;通过长期运行模拟,分析系统的启动特性,并得到6月1日的最佳预冷时间为50分41秒。

Taking the air conditioning of capillary radiation ceiling and fresh air system in an office building in Hengyang as a simulation object by TRNSYS software, the temperature of ceiling, the dew point temperaaxre and dry bulb temperature dynamic characteristics under different starting model was analyzed. The results showed that opening the capillary radiation ceiling and fresh air system at the same time, condensation will occur. It is necessary to open the fresh air system in advance. When the water flow is increased, the system has little influence on the precooling time. Analyzing the system...
