本设计主要依据国家规范、行业标准、品牌品质、舒适环保、经济实用、高效可靠、豪华美观、操作简便、维护便利的原则，提供空调方案，设计合理的中央空调系统，为室内工作人员、客人等提供一个舒适健康的环境。该建筑总共为七层，建筑总面积为1890m2，其中空调面积为1157m2。首层层高为4.2m，二层以上层高均为3.6m，建筑总高度22.0m。夏季室内总冷负荷为268624W，夏季室内冷负荷指标为142.1W/m2。空调房间类型主要为商店、商场、健身房、咖啡厅。使用鸿业暖通空调负荷计算软件8.0对该建筑空调房间区域进行负荷计算。本设计根据该建筑各部分的结构特点及其用途，在充分考虑室内环境的舒适性、运行管理上的方便和节能等各方面的基础上，并依据有关规范考虑节能和舒适性要求，从满足顾客舒适度及空调系统运行节能的角度出发，49014

系统采用风机盘管加新风系统，为满足房间舒适性新风要求，每层单独设一台新风机组，每个空调场所的送回风系统形成一个空气循环，室内温度分布均匀，气流组织好，利用高质量开关，房间温度控制精确，可以满足不同场所的各种空调要求。系统新风机组、风机盘管均暗装于吊顶内，免去了擦洗及维护的麻烦，有效的回风过滤系统延长了空调的寿命，也减少了后期的维护维修费用。

按房间的空间结构布置送回风管的走向，采用上送上回方式，送风均采用方形散流器，风机盘管回风采用条缝风口；可充分利用吊顶，在房间的吊顶内放置风机盘管，实现上送风，风口采用方形散流器。

空调系统夏季供回水温度：7—12摄氏度,冬季供回水温度：65—50摄氏度。空调水系统水管采用异程设计、二管制系统、冷水泵定流量泵，一用一备。在屋顶设膨胀水箱对冷热水系统定压补水，回水管均以0.003坡度坡向供水方向，冷凝水管按排水方向以0.01的坡度找坡，就近排至卫生间。

设计期间主要参考的技术资料有《采暖通风与空气调节设计规范》(GB50019—2003)、《建筑给水排水及采暖工程施工质量验收规范》(GB50242—2002)、《暖通空调制图标准》(GB／T50114—2001)、《实用供热空调设计手册》。

Air conditioning system design of Tonglian building.

This design is mainly on the basis of the national standards, industry standards, brand quality, comfort and environmental protection, economical and practical, efficient and reliable, luxury, beautiful appearance, convenient operation, and convenient maintenance, providing air conditioning scheme, the rational design of central air-conditioning system, indoor staff, guests provide a healthy and comfortable environment. The building a total of seven floors, the total construction area of 1890m2, of which the air conditioning area of 1157m2. The first storey is 4.2m, the height of two floors are 3.6m, the total height of the building is 22.0m. The indoor total cooling load is 268624W, the indoor cooling load index is 142.1W/m2. Air conditioning room type mainly for shops, shopping malls, gym, coffee shop. The use of Hongye HVAC load calculation software of the air conditioning room 8 building area for load calculation. This design according to the structure characteristics of each part of the building and its use, in full consideration of the indoor environment comfortable, operation and management of the convenience and saving energy on the basis and in accordance with the relevant norms of consider the energy saving and comfort requirements, from the point of view to meet the customer comfort degree and air conditioning system operation system energy-saving.

Fan coil plus fresh air system is used, in order to meet the requirements of air room comfort, each layer separate a fresh air handling units, each air-conditioned places of air supply and return system to form an air circulation, indoor temperature distribution, good airflow organization, using high quality switches, precise control of the temperature of the room, can meet the requirements of various air conditioners in different places. System fresh air units, fan coil units are concealed in the ceiling, replacing the cleaning and maintenance of the trouble, return air filtration system effective extended life of air-conditioning, but also reduce the late maintenance and repair expense. 七层上海通联大厦空调系统设计+CAD图纸:http://www.751com.cn/gongcheng/lunwen_51816.html
