摘要本次设计为上海某连锁酒店的空调系统设计，旨在通过合理的空调系统设计为室 内人员提供舒适卫生的室内空气环境。该建筑位于上海，共四层，房间类型主要有多 功能餐厅、办公室、会议室、客房、包厢等。83973

该设计要求计算各个房间的冷负荷和湿负荷值，其值包括外围护结构（外墙、外 窗）、照明设备及人体形成的冷负荷和人体散湿引起的湿负荷。根据建筑的功能和性 质及空不同调系统的优缺点及适用场合，本次设计主要采用全空气系统和风机盘管加 独立新风两种系统方案。由冷负荷和湿负荷计算出送风量（包括新风量和回风量）和 风机盘管及新风机组的冷量。最后由冷量和风量来进行设备的选型。风管和水管的水 力计算采用假定流速法，且在计算和选型时要注意经济实用。这些都是本次设计的重 点。完成以上设计计算后需进行风系统和水系统的平面图和系统图的绘制。

Abstract The design of the air conditioning system is designed for a hotel chain in Shanghai,which aims to provide a comfortable and healthy indoor environment for persons in room by designing rational air conditioning system 。The building is located in Shanghai with four floors and there are multifunction restaurants, offices, meeting rooms, guest rooms, boxes and so on。The design requires calculation of cooling load and humidity load value of each room, including the values of cooling loads caused by external structure (walls, exterior windows included), lighting equipment and the human body and humidity load from human body’s scattering wet。 According to the nature and function of different buildings, the advantages and disadvantages of air conditioning system and occasions which various systems are applied to, this design mainly adopts both systems solutions of all-air system and fan coil plus independent fresh air。 According to the cooling load and humidity load ,ventilation rate(including fresh air and return air ) and the cooling capacity of the fan coil and fresh air units is calculated。 Then ventilation rate and the cooling capacity decide equipment selection。 Hydraulic calculation of ducts and pipes use the assumed velocity method, and in the calculation and the equipment selection should pay attention to economy and practicality。 All above are the focus of this design。 But also diagram of air and water systems need be drawn after the completion of the design calculations。

Keywords: cooling load；fan coil plus independent fresh air；all-air system； hydraulic calculation
