成都地区办公建筑复合通风应用效果
Effect of hybrid ventilation application to office buildings in Chengdu
摘要：
提出适合成都地区办公建筑的复合通风运行策略，模拟比较了复合通风、机械通风、自然通风模式下典型办公建筑的室内热环境和能耗状况。结果表明，复合通风模式室内热环境最优，过渡季节舒适时间百分比为60.1%，可接受舒适时间百分比为75.2%，过冷时间少于机械通风模式，过热时间显著少于自然通风模式；复合通风模式风机能耗比机械通风模式低26.9%。
Abstract：
Presents a hybrid ventilation operation strategy suitable for office buildings in Chengdu. Simulates and compares indoor thermal environment and energy consumption of ventilation system in typical office building under the hybrid, mechanical and natural ventilation modes. The results show that the indoor thermal environment in hybrid ventilation mode is better than the other two modes, the percentage of comfortable degree hours reaches to 60.1%, the percentage of acceptable comfortable degree hours is 75.2%, subcooling time is less than that in mechanical ventilation mode and superheat time is much less than that in natural ventilation mode in the transition season, and the energy consumption of the hybrid ventilation system is reduced by 26.9%, compared with the mechanical ventilation mode.
