一、概述变风量系统适用于大多数建筑物,而对那些每当使用就需要冷却的单层、多层和多房间建筑物的内部区域,尤为适合,当与适当的供暖系统结合时,也可以用于外部区域或周边区域。变风量系统里应用的空气,在集中空气处理站被冷却和去湿,在房间恒温器的支配下,经由能改变送风量的终端送入调节区域。在冬季和过渡季,冷却是靠控制新风与回风的混合来保持的。每个变风量终端,以送至空调房间的风量可变的冷风,去匹配或平衡冷
I. INTRODUCTION VAV systems are suitable for most buildings and are particularly suitable for interior areas where single-layer, multi-story and multi-room buildings require cooling whenever they are used. When combined with an appropriate heating system, they are also suitable. Can be used in external or peripheral areas. The air applied in the variable air volume system is cooled and dehumidified at the centralized air treatment station, and is sent to the adjustment area via a terminal that can change the air volume under the control of the room thermostat. In the winter and transition season, cooling is maintained by controlling the mixing of fresh air and return air. Each VAV terminal can match or balance cold air with variable air volume sent to air-conditioned rooms.
