某大酒店空调工程设计 摘 要
本设计为无锡XX大酒店空调工程设计，本人负责地下一层和四层部分。通过方案比较，在负荷计算的基础上，采用了风机盘管加新风和全空气两种空调系统形式。风机盘管为卧式暗装，新风不承担室内负荷，室内回风与新风混合后经双层百叶风口送出；全空气系统为一次回风系统，室内送风采用侧送风方式，风口为双层百叶风口。新风从墙洞或新风竖井引入，再由机房的新风机组集中处理供应。冷冻水由地下室的冷冻机房供应，
采用了闭式异程两管制水系统。水管用泡沫橡塑保温，风管采用离心玻璃棉。设计工程中考虑了消声、减振和防火排烟的措施。

前 言
随着我国国民经济水平的不断提高，建筑业也在持续稳定地向前发展。和前几年建筑业的发展相比，目前的发展商将眼光放的更远，他们不再片面的追求容积率及如何将开发成本降得越低越好，而是更多的考虑以人为本，开发真正舒适度高、建筑质量高的居住及商用建筑。
随着中国加入世贸及承办2008年奥运会，中国将向全世界全面开放。为了适应国际贸易、旅游、及城市建设迅速发展的需要，高层建筑的发展不会停留在过去的发展水平，特
别是对建筑物内的空气品质及舒适程度的要求也会越来越高。新建的大中商业建筑纷纷安装了空调系统，以提高商场的档次，吸引更多的顾客。各大城市中频频展开的“商战”更加速了空调系统 在商业建筑中的普及。
商业建筑不断的增多，以及人们对室内空气的温湿度、洁净度和空气品质问题越来越重视。由于能源的紧缺，节能问题越来越引起人们的重视。因此迫切需要为商业建筑物安装配置节能、健康、舒适的中央空调系统来满足人们对高生活水平的追求。
