暖通空调 说明书

暖通空调说明书安徽建筑大学摘要本次设计课题是合肥市某高层空调工程设计，为创造良好的室内环境，根据房间不同的使用功能设计了合理的不同的空调方式，本工程主要采用新风加风机盘管系统。

对部分大空间采用全空气一次回风系统，气流组织采用散流器顶送、双层百叶侧送。

风道布置力求与土建功能相结合。

空调水系统闭式双管制变流量系统。

采用假定流速法进行风管、水管水力计算。

冷热源的设计充分贯彻了节能的原则，对不同的冷热源设备从性能、能耗指标等方面进行了技术经济比较，确定了最佳方案。

叙述了建筑物防排烟设计及自动控制设计原理。

提出了空调设备消声减振的措施以及保温保冷设计要求。

On the part of the entire air space by a return air system, air flow for casual organization sent the top, double .Baiye side delivery. Road layout to the wind and light of the functions of civil engineering.Closed dual air conditioning water system variable flow control system. Using the assumption that the wind velocity method, plumbing hydraulic calculation. Cold and heat source of energy-saving design of the full implementation of the principlesfor the different cold and heat source equipment from the performance, energy consumption indicators, such as the technical aspects of the economy, identify the best programme. Describes the design of buildings and smoke-control design principle. By the vibration of the air-conditioning silencer-cold insulation measures and design requirements.Key words: system-wide air chiller air system water fan coil airdistribution system Muffler vibration energy-saving insulation-cold第 2 页安徽建筑大学目录1 工程概况 ........................................................................... .
