1、摘 要本体育文化中心位于安徽省淮南市，由体育馆、综合训练馆、多功能会议厅等相关体育设施组成。本体育馆为多功能体育馆，可进行球类、体操、文艺演出等。本设计从技术性、经济性、节能性、舒适性等方面考虑，对该建筑进行暖通空调方案设计。本设计通过技术经济性分析确定空调方案，由负荷计算进行设备选型，完成新风及水系统分区，确定风管及水管的布置，由水力计算得到风管和水管的尺寸，风压及水泵扬程；完成冷热源机房及空调机房的布置。本体育文化中心的比赛大厅、健身俱乐部、商服、观众休息厅和会议大厅区域面积大，热湿负荷变化情况类似，新风量变化大且室内散湿量大；空调形式采用集中式定风量单风道全空气露点送风一次回风系统；附属
2、用房由于房间较多，房间面积较小且各个房间要求的温湿度不一致，所以对于这些房间采用风机盘管加新风系统，新风处理到室内等焓点再送入室内；部分房间由于使用时间和功能上的不同则独立采用多联机系统。气流组织上，比赛大厅要求送风气流能在观众区形成均匀的温度场和速度场，观众无吹风感，并尽量避免脑后风；观众看台上部和下部的温差不能太大，最好不超过2；送风气流能满足比赛场地各种不同体育项目比赛的要求，例如小球比赛时，风速不超过0.2m/s，其他比赛时风速不超过0.5m/s。比赛大厅与会议大厅属于大空间建筑，根据大空间建筑的特点,本设计从节能的角度上运用了分层空调的理念，在比赛大厅与会议大厅中使用喷口侧送侧回的气
3、流组织方式，使整个观众席处于回流区，避免了脑后风。在风速控制上，本设计按场地最小风速设计喷口尺寸与数量，当比赛场地进行羽毛球等小球运动时，所有喷口全部送风，场地风速满足小球比赛要求；当场地进行其他比赛活动时，可考虑停止部分喷口送风。在比赛大厅其余部分地区采用了座椅送风的气流组织方式。这样整个大厅只有工作区处于空调区，而大厅上部则采用机械排风的方式排掉多余热量。根据本体育文化中心及周围环境的特点，冷热源采用了冷水机组加锅炉的形式。关键词： 体育馆；空调设计；大空间；气流组织第III页AbstractThe sports and cultural center is located in Huai
4、nan City, Anhui Province. It consists of the gymnasium, comprehensive training hall, multifunctional conference room, and other related sports facilities. The gymnasium is multifunctional which can hold balls, gymnastics and theatrical performances. The project focuses on technology, economy, energy
5、 saving and comfort to design the HVAC system for this building.The project makes the air conditioning scheme by technical and economic analysis and selects the equipment by the load calculation. The partition of primary air and water system was completed to work out the layout of the air pipe and w
6、ater pipe. The size of the air pipe and water pipe, the air pressure and the lift of the pump comes from hydraulic calculation. Then the layout of the cooling and heating generator room and air conditioning room are worked out.The characteristics of the competition hall, health club, store, audience
7、 lounge and conference hall are that they contain large place, share similar change of heat and moisture and have big change of primary air and indoor moisture gain. So these areas use the all air system where the air is handed at dew point. There are many auxiliary rooms which are small with differ
8、ent temperature and humidity requirements. These rooms use the primary air fan-coil system in which the primary air will be sent to the room when it is handled to the indoor isenthalpic point. Some rooms use the VRV system for different using time and function. In air distribution, the gymnasium hal
9、l requires uniform temperature and velocity field，no hair feeling in the audience and trys to avoid the back of the wind. The temperature difference between the upper and the lower part of the audience should not be too large and it had better be within 2. The air velocity can meet the requirements
10、of various sports competitions. For example，the field can offer the air velocity within 0.2m/s for small ball games and other games within 0.5m/s. The gymnasium and the conference hall are spacious and according to the characteristic of room buildings，so the design uses the vent air supply in the co
11、mpetition hall and conference hall with the concept of stratified air conditioning from energy saving. The vent air supply is used in the competition hall and conference hall. The vents are installed on the flank wall，so the audience is in the recirculation zone. In the air velocity control，the size
12、 and amount of the vent are designed under the lowest velocity of the field. When badminton games are played on the field，all the vents should be opened to make the velocity for the requirements. When other games are played，some vents can be closed. Other places in the gymnasium hall use the chair a
13、ir supply. Then only the working area is in the air conditioning area while in the upper of the hall mechanical ventilation is used to drain the excess heat. According to the characteristics of the sports and cultural center and the environment around the building, the cooling and heating source tak
