岭南传统建筑冷巷热环境实测分析

Measurement and Analysis of Thermal Environment in Cold Lane of Lingnan Traditional Architecture

通过对具有典型岭南传统建筑特点的广州陈家祠冷巷进行实际测量,结合实测数据分析和数值模拟结果,提出冷巷自然通风是风压和热压共同作用的结果,保持冷巷布置与地区主导风向一致,有利于冷巷自然通风。冷巷的存在一方面加强了建筑周边空气流动,改善了建筑热环境;同时也滞缓了室内空气温度的上升幅度和峰值,对维持室内热舒适性起到一定的作用,具有"自然空调"的效果。建筑周边植被对改善建筑热环境也起到了重要作用。

Based on the actual measurement of Guangzhou Chen Clan Academy which has the typical architectural features of the Lingnan traditional architecture. Combined with the measured data analysis and numerical simulation, the natural ventilation of the cold lane is the result of a combination of wind pressure and hot pressing. The cold lane is consistent with dominant wind direction which can be benefit for the natural ventilation. Cold lane can strengthen the air flow around the building that improve the thermal environment, on the other hand, also slow the rise and the peak of the indoor air temperature which play a role in maintaining the indoor thermal comfort, and has a ＂natural air conditioning＂effect. The vegetation that surrounds the building has also play an import role to improve the building thermal environment.
