Load calculation using the hourly cooling load coefficient method, item by item, calculate and collect, the maximum value of the building cooling load for 2184.6 Kw, so the cooling load per unit area index 169 w /㎡, select two 1055 Kw screw water chillers as cold source, and layout in underground cooling machine, and the corresponding two FBLSS250 standardsof ultra low noise square counterflowcooling tower for evaporative cooling.Due to the nanchang is hot summer and cold winter area, terminal equipment selection should first meet summer air conditioning use, adopts full air, full of water, air and water and cooling system. Among them, such as hall, conference room, restaurant,moisture load and larger space up to the room with full air system; The rest of the storey height is low but the space is lesser, such as office, dormitory is designed,if the layer is set for the condition is designed for air fresh air - water system, if unable to provide centralized air, is set to the whole water system;To meet the requirementsof teaching, at the same time,cultural entertainment room for cooling split type air conditioning system, at the same time choose duct invisible air conditioning indoor machine, and choose a 18 HP cold quantity of split type air conditioning separate-bodied air-conditioners for cooling.

The design for nanchang city fire detachment command center building air-conditioning and ventilation and smoke control design. The building a total height of 99 m, including 1 floor underground, the ground layer 2 tower 23 layer, podium, air conditioning area of 12935.62㎡. The ground building features include registration hall, exhibition hall, entertainment gymnasium, office, dormitory, conference room, restaurant etc. For design task, according to the specification of the original data for cold and heat source design of this building, to the upper air conditioning, ventilation and smoke control design underground ventilation and smoke control design. Design requirements meet hvac professional construction drawing drawing requirements, design content under the condition of satisfy the corresponding specification need as much as possible to ensure comfort, building energy conservation and indoor noise control.
负荷计算采用冷负荷系数法逐时逐项计算并汇总，该建筑冷负荷综合最大值为2184.6Kw，故单位面积冷负荷指标169w/㎡，选择2台1055Kw的螺杆式冷水机组作为冷源，并布置于地下层制冷机房，与之对应2台FBLSS250标准超低噪声方形逆流式冷却塔进行蒸发冷却。由于南昌属冬冷夏热地区，末端设备选型应优先满足夏季空调使用。其中，如大厅、会议室、餐厅、大型教室等人员较多、湿负荷较大且空间高达的房间采用全空气系统；其余层高较低但空间较小的如办公室、宿舍值班室等均采用风机盘管系统，若该层有集中供新风的条件则设计为空气-水系统，若无法提供集中送新风，则设置为全水系统；为满足教学要求，同时将二层阅览室、文化娱乐房间设置为冷剂多联式空调系统，同时选择风管内藏式空调室内机，并选用一台18HP冷量的多联式空调室外机进行供冷。
On the building wall pipeline fan for each toilet is ventilated take a breath, and keep 2 times/h, 5 ~ 10 pa negative pressure ventilation.At the same time to separate the kitchen smoke emissions, and organize the concentration of exhaust flue gas well, keep 3 times/h, 5 ~ 10 pa negative pressure.To ensure the safety of building fire personnel escape to the corresponding building smoke control design, giving priority to open the form of natural smoke exhaust outside the window, if can't meet the requirements of natural smoke extraction using mechanical smoke/smoke, underground garage using exhaust smoke of a two-speed fan to solve the exhaust smoke requirements.

前言
我国经济正在高速发展，人们对于人居、办公环境的舒适度、卫生程度以及安全性提出了更高的要求，空气调节、通风、防火及排烟技术已是保证室内良好环境的必要技术也是建筑消防安全性的需要。而当相关技术的进步与发展同时近年来能源危机的出现、环保要求的不断提高，对于暖通这个高能耗专业提出了更为严峻的要求与挑战。
For indoor and outdoor can produce large noise and vibration of equipment will be carried out in accordance with the specification requirements, shock absorption.And the corresponding pipe insulation to take certain measures to control indoor new wind force and choose to have frequency conversion function COP or equipment. The rest of the actual design and construction need to communicate with the relevant professional cooperationto deal with practical problems.
为提高卫生间空气品质，对该建筑各卫生间安装墙装管道式排风扇进行通风换气，并保持2次/h、5~10Pa的负压排风。同时对厨房烟气进行单独排放，并组织烟气井集中排烟，保持3次/h，5~10Pa负压。为保证建筑火灾时人员逃生的安全，对大楼进行了相应的防排烟设计，优先考虑开启外窗的自然排烟形式，若无法满足自然排烟要求则采用机械防烟/排烟，地下车库采用排风排烟双速风机以解决排风排烟要求。
