摘要 幼儿园活动室是幼儿在园停留时间最长的空间,其室内热舒适对幼儿身心健康发展具有重要意义。对于湿热地区的幼儿园来说,由于夏季时间较长,制凉设备的使用对室内热舒适的提高至关重要。因此,以广州市某幼儿园活动室作为研究对象,以儿童热舒适及建筑能耗作为评价指标,对幼儿园活动室使用不同制凉模式(单独使用吊扇、单独使用空调以及空调与吊扇混合使用)后的环境影响进行研究,通过使用建筑性能模拟软件Ladybug与Honeybee,计算不同制凉模式下室内儿童热舒适度及制冷能耗。通过横向比较发现,吊扇与空调组合使用且吊扇低档位运行时,空调制冷点可以调至30℃。在相同的室内热舒适时长下,空调和吊扇的混合使用比单独使用空调更加节能。 Activity rooms are the space where children spend the longest time in kindergartens.Their indoor thermal comfort is,therefore,crucial to the healthy development of children.For kindergartens in hot and humid areas,cooling is essential to improve thermal comfort during the long summer.Thus,a kindergarten activity room in Guangzhou was taken as an example.Impacts of using different cooling modes(i.e.,using ceiling fans,air conditioning,or mixed-use of air conditioning and ceiling fans)in the kindergarten activity room were investigated,by evaluating children’s thermal comfort and building energy consumption.Indoor thermal comfort of children and cooling energy consumption of the activity room under different cooling modes were simulated by using building performance simulation software Ladybug and Honeybee.By cross-comparison,the results show that the cooling point of the air conditioner can be lowered to 30℃if the ceiling fan is running in low gear and used in combination with air conditioning.For achieving the same indoor thermal comfort duration,mixed-using air conditioning and ceiling fans can save cooling energy compared with using air conditioning only.
