本文以一个分别采用卡顶式和卧式暗装型干式风机盘管加独立新风空调系统的办公室为分析实例,运用CFD方法对独立新风系统在采用上送上回、下送上回以及上送下回三种送排风形式下夏季室内的温度场和速度场作了数值模拟,分析了不同送排风形式对室内气流组织的影响。得出如下结论:对于办公建筑,无论是采用卡顶式还是卧式暗装型干式风机盘管,结合上送下回的独立新风系统送排风形式,室内具有更好的气流组织,热舒适性更佳。
In this paper, a respectively using top-level and horizontal concealed dry-type fan coil plus an independent fresh air-conditioning system office for an example, the use of CFD method for independent fresh air system in the use of the upper back, The temperature field and velocity field of the summer indoor under three kinds of sending and exhausting modes are numerically simulated, and the influences of different sending and exhausting modes on the indoor airflow organization are analyzed. Concluded that: For office buildings, whether it is using the top of the card or horizontal concealed dry-type fan coil, combined with the next sent back to the independent fresh air system to send exhaust in the form of indoor air with better organization, hot Comfort is better.
