摘要
为解决辐射吊顶在制冷量和消除湿负荷方面的不足,辐射吊顶加独立新风系统成为了国内外学者们的重点研究对象。通过对贴附射流、置换通风加辐射吊顶系统的比较试验,研究新风的不同送风方式对辐射空调系统制冷能力的影响。结果表明:贴附射流送风方式主要通过增大对流换热量提升辐射空调制冷量,相较于置换通风,其总制冷量有所提高,其中对流换热量提高34.29%,但辐射换热量却有所降低。
In order to solve the problem of cooling capacity and eliminating wet load,the radiant ceiling plus independent fresh air system has become the focus of scholars at home and abroad.The effect of different air supply modes on the cooling capacity of radiant air conditioning system was studied by comparing the attached jet,displacement ventilation and radiant ceiling systems.The results show that the results show that:the attached jet air supply mode mainly increases the cooling capacity of radiant air conditioning by increasing the convection heat transfer.Compared with the displacement ventilation,the total cooling capacity is improved,in which the convection heat transfer is increased by 34.29%,but the radiation heat transfer is reduced.
