Research on Indoor Thermal Comfort and Age of Air in Qilou Street Shop under Mechanical Ventilation Scheme: A Case Study of Nanning Traditional Block in Southern China

In hot summers, air conditioning (AC) and mechanical ventilation (such as fans) are used cooling modes that strongly influence the resultant indoor environment, like thermal comfort quality in shops of a Nanning arcade street (qilou). The circulation mode greatly affects environment level freshness. approaches for effectively improving developed qilou with air-conditioner humid region southern China. Consequently, purpose this study is to assess different schemes order identify best one. By using two indices, i.e., predicted mean vote (PMV) age (AoA), situ measurement numerical simulation conducted investigate humans’ extreme summer. Then, AoA levels summer under three (upper-inlet–upper-outlet, upper-inlet–bottom-outlet, side-inlet–side-outlet) comparatively analyzed through computations environment. results show upper-inlet–upper-outlet AC scheme led creation favorable comfortable inside shop, which will help designers understand on health
