商场建筑能耗不仅与围护结构和设备有关,还与室内环境有关。为了了解重庆商场热环境状况,本文选择了沙坪坝区4座全年使用中央空调系统的大型商场进行室内温、湿度测量。结果显示,多层商场冬季楼层温度梯度明显,顶层温度普遍高于18℃,夏季各商场温度为24～26℃,一些商场出现室内温度冬季高于夏季的倒置现象,造成能源浪费。针对人们感觉冬季商场偏热的现象,本文从商场顾客着装分析说明商场舒适温度不同于其他空调建筑,应从舒适、经济、节能来调控商场室内环境。
The energy consumption of shopping mall buildings is not only related to the envelope structure and equipment, but also related to the indoor environment. In order to understand the thermal environment of Chongqing shopping mall, this article selected four large-scale shopping malls in central Shapingba district that use central air-conditioning systems throughout the year to measure indoor temperature and humidity. The results show that the multi-storey shopping malls have obvious winter temperature gradients, the top temperature is generally higher than 18°C, and the shopping malls in summer have a temperature of 24°C to 26°C. Some shopping malls have indoor temperatures that are higher than those in summer, resulting in energy waste. In view of the phenomenon that people feel that the winter shopping mall is hot, this article analyzes from the shopping mall customer dress code that the mall’s comfortable temperature is different from other air-conditioned buildings. It should adjust the indoor environment of the mall from comfort, economy, and energy conservation.
