新风量对冷却吊顶空调系统节能性的影响

Influence of Volume of Fresh Air on Cooling Ceiling Air Conditioning System's Energy Conservation

冷却吊顶空调系统的节能性和新风量的选取直接相关 ,以北京市某办公楼为例 ,分别计算出该建筑采用常规FP +新风系统和冷却吊顶空调系统时的能耗 ,并进行分析比较 ,结果表明 ,当冷却吊顶系统的新风再热后送入室内时 ,若系统新风量较大 ,从运行能耗角度来看 ,应优先选取冷却吊顶系统。

There is direct relation between cooling ceiling air_conditioning system's function of saving energy and choosing the volume of fresh air. This paper set a certain office building in Beijing as an example, calculated, compared and analysed the two system's difference between the fan_coil units plus fresh air system and cooling ceiling air_conditioning system's energy exhaust. In the end, the result shows that when cooling ceiling air_conditioning system's fresh air reheated before it is sent into the room, if there is a large amount of fresh air in the system, from the operate energy exhausted point of view, it is wise to select the cooling ceiling air_conditioning system.
