【摘要】：本文以有集中熱源的辦公室建筑為例,在相同送風(fēng)量和相同送風(fēng)溫度條件下,研究比較了兩種直接向呼吸區(qū)送風(fēng)(豎壁貼附射流加導(dǎo)流板送風(fēng)和層式送風(fēng))的氣流組織特性,分析比較了兩種送風(fēng)方式的溫度場和速度場及溫度和速度隨房間高度的變化.研究結(jié)果表明,兩種送風(fēng)方式下,新風(fēng)都可以直接達到呼吸區(qū)內(nèi),呼吸區(qū)內(nèi)空氣品質(zhì)良好,但豎壁貼附射流加導(dǎo)流板形成的豎壁貼附呼吸區(qū)送風(fēng)可以在工作區(qū)內(nèi)形成一個速度和溫度都更加均勻的空氣湖環(huán)境,且能夠獲得較好的舒適度.該研究為豎壁貼附呼吸區(qū)送風(fēng)的新型氣流組織設(shè)計提供了參考依據(jù).
[Abstract]:Taking an office building with concentrated heat source as an example, under the same air supply rate and the same air supply temperature, this paper studies and compares the airflow structure characteristics of two kinds of direct air supply to the respiratory area (vertical wall attached jet plus guide plate supply air and layer type air supply). The temperature field and velocity field and the variation of temperature and velocity with room height were analyzed and compared. The results show that the fresh air can reach the respiratory zone directly and the air quality in the breathing area is good. But the vertical wall attached to the jet and the baffle formed by the vertical wall attached to the breathing area can form a more uniform air lake environment with more uniform velocity and temperature in the working area, and better comfort can be obtained. This study provides a reference for the design of new airflow organization in the vertical wall attached to the breathing area.
