摘要
本此设计的是北京市中国银行办公大楼的空调系统.针对该办公大楼的功能要求和特点,以及该地气象条件和空调要求,参考有关文献资料对该楼的空调系统进行系统规划,设计计算和设备选型.首先计算各房间的冷负荷;接下来是计算风量,风量的计算包括送风量和回风量的计算.风量的计算之初先在I-d图上画出空气的处理过程,然后根据前面的负荷计算结果进行计算,最后根据需要的风量和冷风量选择空气处理设备.在此基础上,通过对各种空调方式的比较,选择合理的空调系统.。考虑到本建筑的特点,选用集中式风机;并对制冷系统和风系统进行了设计计算.
根据各种计算结果,通过性价比分析,进行设备选型,确保设备容量,压力,噪声等方面满足要求.本空调系统的设计力求达到经济,舒适,方便,实用,并尽可能满足节能要求.
