| 摘 要： | 本文以沈阳某医院住院楼为研究对象,使用FLUENT技术对夏季夜间不同通风条件下室内温度和CO2浓度的分布情况进行数值模拟。同时对沈阳市夏季夜间室外温度及夜间病房室内温度,CO2浓度值进行实时监测,最后将模拟结果与实际监测结果进行对比。沈阳地区早晚温差较大,经研究得出在夏季合理利用室外温度较低的新鲜空气进行夜间通风,不仅可以改善室内空气品质,还能有效降低制冷机组能耗。

| Abstract: | This paper takes the inpatient building of a hospital in Shenyang as the research object,and uses FLUENT technology to numerically simulate the distribution of indoor temperature and CO2 concentration under different ventilation conditions in summer and night.At the same time,the outdoor temperature and nighttime ward indoor temperature and CO2 concentration value of Shenyang City were monitored in real time,and the simulation results were compared with the actual monitoring results.The temperature difference between morning and evening in Shenyang area is relatively large.It has been found that the use of fresh air with low outdoor temperature for nighttime ventilation in summer can not only improve indoor air quality,but also effectively reduce the energy consumption of refrigeration units. |
