摘要
本文测量了顶送风供暖房间不同送风状态对应的室内温度和风速,根据实测数据对室内人员热舒适性进行了分析,指出在地面附近有较大热损失的房间,减小送风温差可以在一定程度上改善室内温度分布。仅改变送风参数不能从根本上解决这类房间近地面热舒适差的问题。
The temperature and the velocity of indoor air in different supply air conditions under ceiling hot air supply mode were measured. Based on the data, the human thermal comfort was analyzed and it was found that decreasing the supply air temperature could improve the temperature distribution on a certain level, but poor thermal comfort near the ground can not be solved completely by only changing supply air parameters.
