Developing Office Building Design and Operation Strategies Using UWENSOL and the Comfort Routine 使用UWENSOL和舒适程序开发办公楼设计和运营策略
本案例研究的结果报告以参考测试的描述开始。最初,我们通过考虑外墙完全上釉来模拟这间单人办公室的性能。竖梃和其他框架构件被忽略。对于所研究的一天,绘制了三个内部建筑表面的温度与外部环境干球温度的关系图。玻璃墙(南立面)的温度与外部空气温度密切相关,而北墙和吊顶的温度值与固定空气温度相似。 2摄氏度(72华氏度)。后两种温度分别在下午1点和中午之前低于室温。然后,每一个都超过环境空气温度四小时。UWENSOL对系统负荷要求的计算结果表明,房间的冷负荷从中午开始,一直持续到下午6点。在此之前和之后,需要加热以保持22.2°C(72°F)的固定空气温度。通过使用省煤器循环增加送风的外部空气成分,可以满足这种冷却需求。 引文:研讨会,ASHRAE交易,第86卷,第一部分,加利福尼亚州洛杉矶
We begin the report of the results for this case study with a description of a reference test. Initially we simulated the performance of this one-occupant office by considering the exterior wall to be entirely glazed. Mullions and other framing members were ignored. For the day studied, the temperatures at three of the internal building surfaces are plotted versus the ambient external dry-bulb temperature. The temperature at the glazed wall (south elevation) closely follows the external air temperature, whereas the values at the north wall and the suspended ceiling are similar to the fixed air temperature 22.2°C (72°F). These latter two temperatures can be seen to be lower than the room air temperature until 1 p.m. and noon, respectively. Each then exceeds the ambient air temperature for a period of four hours. The results of the UWENSOL calculations of systems load requirements indicate that the room would have a cooling load beginning at noon and continuing until 6 p.m. Previous to that period and following it heating would be required to maintain the 22.2°C (72°F) fixed air temperature. Presumably this cooling need would be satisfied by increasing the outside air component of the supply air by using an economizer cycle.
