摘要(Abstract)：

辐射吊顶供冷空凋系统可将室内显热负荷与湿负荷分开处理,采用辐射方式处理显热负荷,送风承担湿负荷,同时也承担一部分室内显热负荷。本文对辐射吊顶空调系统中的除湿特性进行研究,针对辐射吊顶供冷的结露问题,提出预除湿负荷概念,并计算不同设计条件下的预除湿负荷,探讨了表冷式空气处理机组作为除湿设备的容量确定方法。本文最后以上海X别墅辐射吊顶+置换通风空调系统为测试对象,对该系统除湿特性进行了实测分析。
The sensible and latent heat loads could be treated separately in the radiant ceiling cooling air-conditioning system,in which supply air was used to remove the moisture and a part of sensible heat load generated from the indoor space,while a radiation panel was used to remove the sensible heat load.Dehumidification characteristics of radiant ceiling air-conditioning system were studied in this paper;the concept of pre-dehumidification load was proposed to prevent the condensation problem of radiant ceiling cooling and the load is also calculated under different designed conditions.The method of selection for the air handling units was discussed.Finally,The dehumidification characteristics of radiant ceiling and displacement ventilation system in a shanghai villa was studied.
