办公室热舒适与空调运行特点研究*
Thermal comfort and air conditioning operation characteristics of office buildings
摘要：
以长沙市某办公楼为研究对象，对不同类型办公室内及室外温湿度和空调末端能耗进行了现场实测，分析了室内热舒适性与办公建筑空调系统运行特点。结果表明：办公室室内热环境良好，室内温度日变化趋势相对稳定，湿度较大，室内热环境在突变环境和稳态环境下均能满足办公人员舒适度要求；在办公人员主观空调行为作用下，室内日平均温度约为25.1 ℃，受室外日平均温度影响较小，空调制冷时长与室外日平均温度显著线性相关；门厅空调开启概率最大，大办公室室内空调平均开启概率小于小办公室。
Abstract：
Taking an office building in Changsha as the research object, tests the indoor and outdoor temperature and humidity of different types of offices and the energy consumption of air conditioning terminals, and analyses the indoor thermal comfort and the operation characteristics of air conditioning systems in office buildings. The results show that the indoor thermal environment is good, the daily change trend of indoor temperature is relatively stable, the humidity is high, and the indoor thermal environment can meet the requirements of the occupants comfort in both sudden change and stable state environments. With the subjective air conditioning usage behavior of the occupants, the daily indoor mean temperature is about 25.1 ℃, which is less affected by the daily outdoor mean temperature, and the cooling time of air conditioners is significantly linearly related to the daily outdoor mean temperature. The air conditioner in the lobby has the highest opening probability, and the average opening probability of indoor air conditioners in the large office is less than that in the small office.
