本文提出并研究了一种新型的太阳能温差电致冷吊顶与置换通风系统的结合。STCC-DV系统采用热电模块代替传统的液体循环管道作为热源，利用热电除湿系统对新风进行除湿。冷却天花板和除湿通风系统均由光伏系统供电。在我们的研究的这个阶段，我们正在开发一个太阳能热电冷却天花板（STCC）系统，通过使用商业TE技术。实验是在实验室中进行的，辐射板的尺寸为1800 × 600 mm。结果表明，工作电压、环境温度和室内温度对太阳能电池板的总热流密度和性能系数有很大影响。STCC系统在制冷工况下的总热流密度大于60 W/m2，在5V工作电压下，系统COP可达0.9。在制热模式下，STCC系统在4V工作电压下的总热流密度大于110 W/m2，系统的COP可达1.9。这种简单、环保的系统在低碳建筑的气候控制中具有广阔的应用前景。
A novel solar thermoelectric cooled ceiling combined with displacement ventilation system (STCC-DV) is proposed and investigated in this paper. In STCC-DV system, thermoelectric modules are employed as heating source instead of conventional hydronic pipe, and the combined system dehumidifies the fresh air using a thermoelectric dehumidified system. Both the cooled ceiling and dehumidified ventilation system are powered by PV system. At this stage of our study, we are developing a solar thermoelectric cooled ceiling (STCC) system by using commercially TE technologies. The experiments have been done in a test room using radiant panels whose dimension is 1800 × 600 mm. The results show that the total heat flux and COP of the panel are strongly influenced by operating voltage, ambient temperature and indoor temperature. The total heat flux of the STCC system in cooling mode is higher than 60 W/m2and the system COP can reaches 0.9 under operating voltage 5 V. In heating mode, the total heat flux of the STCC system under operating voltage 4 V is higher than 110 W/m2and the COP of the system can reaches 1.9. This simply and environmentally friendly system is promising and worthwhile being applied to for low carbon buildings climate control.
