Environmental Controls and Safety 机电关键技术简介 Introduction of MEP Technologies The project establishes a high and a low energy center. The high energy center area employs a conventional centrifugal refrigeration unit system while the low energy center area is in the form of multi-cold source. This includes cooling-heating-power system, conventional electric refrigeration system, ground-source heat pump system, and ice storage system. The electro-mechanical system of the Shanghai Tower is particularly complex due to the tower'

s height and unique architectural style (see Figure 4.1). The design of the electro-mechanical system applies advanced technology to sustainably generate energy because it strives for a Green 3-Star and a LEED Gold Award. The heightened commercial use of the building space puts forward higher requirements on the electro-mechanical system. The introduction mainly includes the design and the manufacturing of ultra-silent: air handling units, ice storage systems, CPMS-Energies Management Systems, cooling-heating-power supply systems, sewage treatment reuse systems, integrated power supervisory systems, special lighting designs, BIM applications of electro-mechanical detailed designs, along with special construction schemes and technologies. The Design and Manufacturing of Ultra-Silent Air Handling Units Top grade office floors in Shanghai Tower are located in Zones 2C6. The maximum area of the floors cover 4,600 square meters. The minimum area is 2,400 square meters, and most of the stories are 4.5 meters in height. The depth of beam is about 700mm. There is

150 mm raised flooring setting requiring 3-meter ceiling heights. The space for the electro-mechanical pipeline inside the ceiling is limited. The layout of the core tube is a nine-rectangle-grid, while the effective usable space of office conforms to an annular plane layout. Vertical elevators of each district are set up in a nine-rectangle-grid core tube and the rooms and shafts of electromechanical equipment are intensively arranged along the core tube. Consequently, the core tube limits the space and area reserved for mechanical and electrical equipment. The air conditioning facilities and large office spaces and corridors are separated by only a wall, which saves space. In order to meet the required building'

s energy efficiency quota, many interventions occurred. For instance, Shanghai Tower maximizes utilization ratios of architectural Zhenghong Liu, Shanghai Tower Construction &

Development Co., Ltd. 刘正红, 上海中心大厦建设发展有限公司 This chapter explains that, in addition to Shanghai Tower'

s peculiar height and unique architectural style, the project also targets a Green 3-Star and a LEED Gold certification. The complexity of its electromechanical system required advanced technology to create sufficient energy for the tower. The chapter endeavors to display the commercial use of the building space and how rigorous solutions to the electromechanical systems are required. Further, the management of system integration control and the application of BIM to electromechanical detailed design is elaborated upon. 本文简单介绍了上海中心大厦项目因其特有的高度和独特的建筑造型,及绿色三星和LEED金奖的建设目标设定,其机电系统的庞 大和复杂性,运用了较多的先进机电技术和可持续发展能源;
