The design of this air-conditioning system has no zone divisions, it applies the centralized system.
The form of air conditioning uses the isolated outdoor air and fan-coil unit system and the full fresh air system, this form of design can save energy as well as satisfy the requirements of the indoor environment. Hourly coefficient method is used for the cooling load calculation, while the hydraulic computation uses the hypothetical flow rate method with the aid of Hongye hydraulic computation software, and CAD is used for all the drawings.

本空调系统设计不分区，选用集中式空调系统。空调系统形式选用独立新风与风机盘管系统和全新风系统，这样既可以节约能源又能满足室内环境要求。本设计冷负荷计算采用冷负荷逐时系数法，水力计算采用假定流速法应用鸿业水力计算软件，所有的绘图均采用CAD制图等。
