无锡大型办公大楼中央空调系统设计+CAD图纸(2)
随着社会的不断进步，经济的快速发展，生态环境以及能源问题的严重。人们开始注意到可持续发展的重要性。中央空调系统是一个巨大并且繁杂的系统，能源消耗非常大，所以对实行节能有很大发展。在进行系统规划的过程，关于系统和设备的选型，此次设计考虑了节能的需求。以及对暖通空调系统的设计，所有环节都非常严格的按照国家、地区以及行业的标准和规范执行，做到用心的设计。
General Description of Design
The design for the Wuxi Puguang building air conditioning system. Wuxi Puguang building is a small and medium-sized office building office building, All floor area about buildings are about 11554m².There are 20 floor of the building, the whole floor are using Cetral Cooling Chiller to focus on the way . This design of the main room of the building for office, most of them is very short, and some of them are not connectd, this selected air-conditioning systems can achieve independent control for each room, considering the various factors to determine the selection of plus fresh air systems. Arrangement on the room units, use the dark form the equipment. Set the focus on fan coil system, plus the independent air system, fresh air from the outdoor unit to deal with the introduction of a new wind to the indoor air enthalpy value, are not bearing the load of indoor. All bear the indoor fan-coil cooling load and part of its new rheumatoid load. Plus an independent air systems sent by Venetian and the other side air delivery.Based on the relevant manuals provided ,and further completion of the new air units, water pumps, hot water units, such as the selection, which will be reflected in their drawings, the last design for the entire air conditioning system.
At first, I calculate cold load in this design, then sure air conditioning system forms, selected and layout terminal device equipment. hydraulic calculation after identifying pipe and duct diameters, then complete plan design.
Office buildings usually include both peripheral and interior zone spaces. The peripheral zone extends 3 to 3.6 m inward from the outer wall toward the interior of the building, and frequently has a large window area. These zones may be extensively subpided. Peripheral zones have variable loads because of changing sun position and weather. These zones typically require heating in winter. During intermediate seasons, one side of the building may require cooling, while another side requires heating. However, the interior zone spaces usually require a fairly uniform cooling rate throughout the year because their thermal loads are derived almost entirely from lights, office equipment, and people. Interior space conditioning is often by systems that have control for low- or no-load conditions.
Most office buildings are occupied from approximately 8:00 am to 6:00 pm; many are occupied by some personnel from as early as 5:30 am to as late as 7:00 pm. Some tenants’ operations may require night work schedules, usually not beyond 10:00 pm. Office buildings may contain printing facilities, information and computing centers, or broadcasting studios, which could operate 24 h per day. Therefore, for economical air-conditioning design, the intended uses of an office building must be well established before design development.
