1、摘要本设计是上海市某酒店空调工程设计，酒店共六层，建筑总面积11476㎡，空调面积为7710㎡，其中一层不做设计要求。空调区夏季冷负荷为411.48kW,冬季热负荷为312.98kW。根据房间功能，确定出了空气—水、全空气系统在该酒店的具体应用场所。考虑到经济性以及可行性，得出了一套空调系统方案，并针对此方案进行了水力计算、设备选型等。对于消声减震也做了一定的设计。在风系统设计中，二层餐厅以及五、六层多功能厅属于高大空间场所，采用全空气一次回风系统。舒适性空调系统，采用机器露点送风，省去了再热量。空调机组放在机房或吊装在走廊。对
2、于二层的套房、办公室和三至四层的商务用房，由于其空调负荷变化较大，且各个房间的朝向、使用时间不同，采用风机盘管加新风系统。新风处理到室内等焓状态点，不承担室内负荷。在水系统设计中，闭式系统腐蚀性弱、水泵扬程小，系统简单。异程系统管路布置简单，阻力通过增设阀门来调节。定流量系统不需要复杂的自控设备。根据负荷计算可知，宾馆不需要同时供冷、供热。所以设计中采用闭式、异程、定流量、两管制系统。结合地理位置，空调冷热源采用了水源热泵机组。关键词：冷负荷，露点送风，等焓状态点，异程，水源热泵ABSTRACTThedesignisaircon
