摘要通过对广州市某体育馆进行通风空调系统设计，系统地阐述了体育馆暖通空调的设计方法和步骤,前期工作中负荷计算与普通的建筑负荷计算无太大区别，后期绘制通风空调施工图，需分两个系统分别绘制，一部分是体育馆各功能房间的空调通风，采用风机盘管加新风的系统，另一部风是为观众席、比赛大厅，通过喷口送风，座位下回风的全空气系统。风机盘管加新风的方式在小空间中是较为常见的空调通风方式，新风是否经风机盘管再处理，会影响负荷计算和风机盘管的选型；喷口侧向送风，座位下回风方式，对射流末端风速、末端温度与周围环境温度的差值有一定的要求，这是体育馆观众席、比赛大厅空调的设计校核的关键。9743

Title A ventilation and air conditioning engineering design for a gymnasium in Guangzhou
Abstract
Through the ventilation and air conditioning engineering design for a gymnasium in Guangzhou, this specification talks about design methods and procedure of heating, ventilation, and air conditioning (HVAC) for a gymnasium. There is no much difference between load calculation in gymnasium and common building load calculation in the early work. It needs two systems to draw air conditioning drawings in the later work, one part is the ventilation and air conditioning for function rooms, which uses air fan coil with fresh air system, the other part using nozzles to send air to the auditorium and competition hall, and air returning under the seats, which adopts all air system. Air fan coil with fresh air system is common in little space, whether the fresh air dealt by the fan coil can affect load calculation and fan coil selection. The type of lateral air supply by nozzles and air returning under the seats, has certain requirements at jet end wind speed, and the difference between jet end temperature and surrounding environment temperature, which is the key point for the system design check.
