天棚辐射供冷系统调节性能的研究
Regulation performance of cooling ceiling air conditioning system
摘要：
采用TRNSYS软件对上海某办公室的天棚辐射板+独立新风系统进行了模拟。探讨了开关控制下，定水温、变水温控制对房间温度稳定性、结露发生频率以及人体热舒适性的影响。结合新风除湿对整个系统的运行特点及能耗进行了研究。结果表明两种控制方式能耗相当，且均有较高舒适度，变水温控制可避免结露风险，供冷性能受室内湿度的影响较大。
Abstract：
Simulates the combined air conditioning system of cooling ceiling and dedicated outdoor air system in an office located in Shanghai by TRNSYS. Discusses the influence of both the variable and the constant water supply temperature with on-off control on the stability of indoor temperature, condensation frequency and human thermal comfort. Studies the operational characteristics and energy consumption of the entire system combined with outdoor air dehumidification system. The results show that the energy consumption of two control methods is basically the same and better thermal comfort can be obtained with both methods. The method of variable water supply temperature can avoid the risk of condensation, and its cooling capacity is influenced by the indoor humidity.
