Effect of moisture reduction on thermal comfort by solar chimney window with small ventilation fans
Keywords:
Moisture, Thermal comfort, Solar chimney window, Ventilation, Heat gainAbstract
An experimental study has been conducted on the performance of a solar chimney window with small ventilation fans that also function as an air ventilated stack for moisture content reduction of a residential house. In this study; two rooms without air conditioner were tested, each with a volume 30 m3, one of them served as a reference. Two small fans were installed to supply ventilation corresponding to the number of air change in the test room. Data analysis was made to determine the moisture reduction and heat flow due to ventilation, which were ranged 0.141-6.16 gw/kgda and 0.6-18.5 kJ/kgda, respectively. In addition, heat gain through the window was considered. The result showed that solar chimney window could reduce the average heat gain by about 10.24 W/m2. The experimental result pointed out that solar chimney window is very effective for reducing moisture and providing the indoor thermal comfort.
