分体空调新风引入对室内舒适度影响的实验研究

Experimental Study of Indoor Comfort with Split Air Condition System and Fresh Air Inletting

现代家用分体空调由于无新风引入而使得建筑室内空气品质降低,因此,为了改善室内空气品质,家用分体空调引入新风就很有必要。本文采用机械独立新风引入方式对建筑引入新风,并针对不同新风引入量对室内舒适度的影响进行实验测试,结果表明:家用分体空调引入新风量的大小是影响室内温度场分布的最大因素。低位小新风量空调低风速的工况下室内的热舒适度最高,而低位大新风量空调高风速工况下的室内热舒适度最差。

The buildings with split air - condition makes indoor air quality reduced because there is no fresh air inletting. It is necessary to introduce fresh air in the buildings. In this paper, the fresh air is introduced into the building by the mechanical sup- ply . By experimental studying the indoor comfort at the different fresh air amount and different models of split air - condition, we show that the amount of fresh air is the largest factors of indoor temperature field distribution. The best condition of indoor thermal comfort is the low position, mall fresh inletting, low speed of split air - condition while the worst condition of indoor thermal com- fort is the low position, large fresh inletting, high speed of split air - condition.
