摘　　要：针对传统吊顶冷辐射空调在睡眠环境下热利用效率低的问题,提出了局部冷辐射空调系统.基于CFD模型,研究了局部冷辐射空调和吊顶冷辐射空调的节能性和热舒适性.结果表明,局部辐射空调系统的能量利用效率高于吊顶冷辐射空调系统,且在相同舒适度下,局部辐射空调系统的总换热量显著降低.研究结果可用于进一步改善局部辐射空调系统的实际工作参数和运行策略.To solve the problem of low energy utilization efficiency existing in ceiling radiant cooling panel systems,a radiation-based task/ambient air conditioning(R-TAC)system was proposed.The energy and thermal comfort performances when using the R-TAC systems and the ceiling radiant cooling panel(CRCP)systems were studied with CFD model.The results show that,under the same thermal comfort situations,the energy utilization efficiency when using R-TAC systems was higher than that when using CRCP systems,and the cooling load in R-TAC systems was dramatically reduced.
