摘　　要：对新型沟槽充液式辐射板供冷特性进行研究,利用冬季室外低温环境作为冷源,沟槽内部充有液体,具有较好的蓄冷性能,可在非用电高峰期间储存冷量,用电高峰时释放出来,文中对不同实验工况进行研究、分析,与普通辐射板相比,新型沟槽辐射板室内温度波动较稳定,供冷量为68.4~80.2 W/m^(2),经过后期设计,有着更大的节能潜质,也可减少室内安装面积,具有很好的经济性。This paper studies the cooling characteristics of a new groove liquid filled radiant panel.The outdoor low-temperature environment in winter is used as the cold source.The groove is filled with liquid and has good cold storage performance.It can store the cold capacity during off-peak power consumption and release it during peak power consumption.Different experimental conditions are studied and compared with ordinary radiant panel.The indoor temperature fluctuation of the new grooved radiant panel is relatively stable,and the cooling capacity is 68.4-80.2 W/m^(2).After later design,it has greater energy-saving potential,can also reduce the indoor installation area,and has good economy.
