中文摘要:
      以苏州市采用辐射−新风复合系统的一个次卧室为研究对象,运用TRNSYS软件进行模拟研究。研究在夏季工况下室内设定温度、辐射末端供水流量、供水温度对辐射−新风复合系统室内热环境和室内温度滞后时间的影响,并探究了系统合适的预冷时间。结果表明,在夏季工况下,室内设定温度和供水温度改变时室内热环境变化较大,供水流量对室内热环境有一定的影响,供水流量从220 kg/h增加到260 kg/h时,室内温度达到设定温度的时间提前了1 h,供水流量不同,室内热环境达到稳定的时间也不同;供水温度对室内热环境的影响比供水流量明显,供水温度越低,预计平均舒适度PMV达到Ⅰ级舒适范围的时间越短;为满足室内热舒适的要求可提前1.0~1.5 h开启系统。
英文摘要:
      A secondary bedroom with radiation-fresh air composite system in Suzhou was taken as the research object. By using TRNSYS software simulation method, the influence of indoor setting temperature, radiation terminal water supply flow and water supply temperature on indoor thermal environment and indoor temperature lag time of radiation-fresh air composite system was studied under summer working conditions, and the appropriate precooling time of the system was explored. The results show that the indoor thermal environment changes greatly when the indoor setting temperature and water supply temperature change in summer, and the water supply flow has a certain impact on the indoor thermal environment. When the water supply flow increases from 220 kg/h to 260 kg/h, the time for the indoor temperature to reach the setting temperature is 1.0 h ahead of time. When the water supply flow is different, the time for the indoor thermal environment to reach stability is also different. The impact of water supply temperature on the indoor thermal environment is more obvious than that of water supply flow. Obviously, the lower the water supply temperature is, the shorter the time for PMV to reach class I comfort range is. In order to meet the requirements of indoor thermal comfort, the system can be opened 1.0~1.5 h in advance.
