摘要: 本设计为上海某办公楼中央空调系统的设计。总建筑面积约为3348m2。该建筑从地上一层大厅、展厅设全空气空气调节系统, 空调热媒为60/50℃热水,由换热站提供。办公建筑考虑其单独调节性及舒适要求均采用风机盘管加新风的空调系统。新风机组将新风处理至室内状态焓值直接送入室内，不再另设空气处理装置。建筑消防上对消防楼梯间及电梯前室设置了火灾时加压送风设备。

风机盘管家新风系统除卫生间设置排风系统其他房间的排风均采用自然排风，不单独设置排风系统。各风管上设置防火阀门，平时开启，着火时关闭。风机盘管水系统各层水平主管路为同程布置,水管路系统中最高点设置排气装置(自动排气阀),最低点设置泄水装置(泄水阀门).68720

Design of Central Air Aonditioning System for an Office Building in Shanghai

Abstract: This design is the design of the central air conditioning system of an office building in Shanghai. The total construction area is about 3348m2. The building from the ground floor hall hall, a full air conditioning system, air conditioning heat medium is 60/50 DEG C hot water provided by the heat exchange station. The office building takes into consideration its independent regulation and comfort requirements, and adopts the air conditioning system with fan coil units and fresh air. The fresh air unit treats the fresh air to the room, and the enthalpy is directly sent into the room, and no air treatment device is set up. Building fire set fire to fire the stair and elevator when pressurized air supply equipment.

In addition to the exhaust air system in the toilet, the exhaust air of the other rooms adopts natural ventilation, and the exhaust system is not installed separately. Fire valve is set on each pipe, usually opened and closed when fire. The horizontal water level of fan coil water system is arranged in the same way, the exhaust device (automatic exhaust valve) is set at the highest point in the water pipe system, and the discharge device (drain valve) is installed at the lowest point
