摘 要
本设计为长沙市万达酒店空调设计，夏季供冷，冬季供热。该建筑面积为35305m2,空调面积为31205m2，建筑高度为91.700m。该建筑地下一层，主要为设备房；地上二十五层，其中一至三层为餐厅、会议室、酒吧、，四至二十二层为客房、会议室、宴会厅。
夏季采用冷负荷系数法计算空调冷负荷为1964kw，冬季空调热负荷按稳定传热理论计算为1034kw。按房间功能和使用时间不同，将冷冻水系统在竖向划分为两个区，一至三层为一区，四至二十三层为二区，。该空调系统的冷热源组合方式为两台螺杆式冷水机组供冷，单台制冷量为1010kw；两台真空热水机组供热，单台供热量为582kw。机组置于地下室机房内。
空气调节系统主要如下：湿负荷比较小的空间采用全空气一次回风系统，客房及小空间采用风机盘管加独立新风系统。空气处理设备为风机盘管，吊挂式和立式风柜。
地下室的通风和排烟共用一个系统，地上的楼梯间采用机械防烟加压系统，中庭采用机械排烟。
关键词：空调系统、水系统、风系统、防排烟
Abstract
This design for air conditioning design of changsha wanda hotel, summer cooling and winter heating. The total area of the construction is 35305㎡and air conditioning covers an area of 31205m2. The building height is 91.700 m. The underground of the building is mainly for the equipment room; Twenty-five floors, one to three layers is for restaurants, meeting rooms, bars, and four to twenty-two for guest rooms, meeting rooms, banquet hall .
The summer air conditioning cooling load is 1964 kw by using cooling load coefficient method, the winter air conditioning heat load calculated by stable heat transfer theory is 997 kw. According to the function and use of the time difference, the chilled water system in the vertical is divided into two areas, one to three layers for the area, in two area, four to 23 layer. The air-conditioning system of hot and cold source combination for two screw water chillers and cooling, a single refrigerating capacity is 1010 kw; Two vacuum heating hot water unit, a single heating load is 582 kw. Unit in the basement room.
Air conditioning system is mainly as follows: moisture load smaller space using a return air system, air rooms and a small space with fan coil plus fresh air system independently. For fan coil air handling equipment, hanging type and vertical wind ark. Basement ventilation and smoke exhaust common system, the ground of the stair adopt mechanical smoke pressurized system, adopts the mechanical smoke exhaust the atrium.
Key words: air-conditioning systems, water system, air system, smoke control.
