设计总说明本工程位于上海市，广场四层-九层的总建筑面积为41562.4m²，用于办公商业区，采用中央空调系统。这种系统配置的最大优点是商用中央空调避免了像传统中央空调那样在建筑房屋主体时就得实施，而且特别便利那些原来没有设计安装空调的旧建筑进行重新配置。室内机一般安装在天花上或吊顶上，不占用地面空间，不留卫生死角，房间更显宽阔。商用中央空调运行管理灵活，可以做到一台室内机连接多台室内机，室内机可单独开关控制，满足人体对温度要求的个体差异。商用中央空调温度调节和送风更加均匀，让人感觉更加舒适，新风、加湿功能可使室内空气保持新鲜和卫生，制冷热效果可以与大型中央空调媲美，这都是传统所望尘莫及的。

  本工程位于上海市，广场四层-九层的总建筑面积为41562.4m²。第4-8层各32个房间，包括机房、厕所、办公室，面积各为9266.8m²、8945.6m²、8947.3m²、8948.6m²2946.92m²，用于办公。第9层由10个房间、屋顶花园、厕所、机房等组成面积为2507.02m²也用于办公。

本设计的空调方案采用了全空气系统一次回风系统的形式。全空气系统是完全由空气来担负房间的冷热负荷。一个全空气系统通过输送的冷空气向房间提供冷热量，其空气的冷却、去湿处理全集中于空调机房内的空气处理机组，在房间内不再进行补充冷却，而对输送到房间内的空气的加热可在空调机房内完成，也可在房间内组成。一个全空气系统可以为一个或者多个区服务，其具有以下优点：有专门的过滤段，有较强的空气除湿能力；送风量大。换气充足，空气污染小；在初秋过度季节可实现全新风运行，节约运行能耗。

本设计的冷热源采用了螺杆式冷水机组。此机组不仅可以在夏季提供冷源而且在冬季也可以提供热源，适合无集中供热区。溴化锂冷（热）水机组具有加工简单，操作方便，可实现无极调节，运动部件少，噪声低，振动小，对臭氧成无破坏以及成本低，对热源品味要求不高，运行费用少等优点；热泵机组适合我国夏热冬冷地区具有环保节能，冷热联供，无需冷却水系统和供热锅炉等优点，在我国将发挥越来越重要的作用。

Design general description

    This project is located in Shanghai City, Plaza 4-9 layer - a total construction area of 41562.4m, for the business district office, the use of central air-conditioning system. The big-gest advantage of this system is configured to avoid like the traditional commercial central air conditioning central air conditioning in the main building is implemented, and those who had no special design and installation of air conditioning the old building was reconfigured. The indoor machine is usually installed in the ceiling or ceiling, does not occupy the ground space, leaving no sanitary dead, the room more spacious. Commercial central air conditioning operation is flex-ible, can do a room in the machine is connected with the indoor units, the indoor machine can separate switch control, Meet the body temperature requirements of inpidual differences. The temperature of commercial central air conditioning and air regulation is more uniform, make people feel more comfortable, fresh air, humidifying function can keep indoor air fresh and sani-tary, heat effect can be comparable with the large central air conditioning, which are the tradi-tional unmatched.

This project is located in Shanghai City, Plaza 4-9 layer total construction area of 41562.4m . The 4-8 layers of 32 rooms, including room, toilet, office area for the 9266.8m , 8945.6m , 8947.3m , 8948.6m , 2946.92m, for office. The ninth layer is composed of 10 rooms, Roof garden, toilet room which area is 2507.02m - also for office.
