摘 要
本设计对象是一九层假日酒店，位于武汉市。涉及的主要内容有：负荷计算、新风量的确定、空气处理过程的设计、气流组织设计与计算、设备选型、水系统及风系统水力计算、系统控制的方案确定等。
结合建筑特点与实际，制定空调设计方案。在符合实际的基础上尽量使系统有更强的功能性和操作性，所以本设计采用风机盘管加新风系统，人员少或者停留时间不长且不易送新风的小房间则靠自然通风来达到换气的目的。从第一层至第九层均采用吊顶式空调机组，风机盘管采用下送风的方式。而新风则在客房采用侧送风，其他房间采用下送风
第一层新风机组置于厨房部分的室外，可最大化的减少机组噪音对大厅人员的影响，而从第二层至第九层的新风机组则置于相应的机房里，
制冷机房设于地面一层最西面，选用一台螺杆式冷水机组，夏季供冷冻水，
冷冻水泵选择的是两用一备，冷却水泵选择也是两用一备，冷却塔置于屋顶。 关键字：风机盘管加新风系统；送风方式；制冷机房；水泵
Abstract
The object of this design is a lholidayinn construction which is located in Wuhan. The main content includes:the load computation, the amount determination of new wind, the air treating processes design, the suppose counts with the computation of air current organization, the equipment shaping, the water power computation of aqueous system and the wind system, the systems control plan,and so on.
Combine the practice and the characteristic of architecture,establish the plan of the air condition design. On the basis of truthfulness,making the systerm more functionality and more operationality.So we design the Fan coil and fresh air system ,The small room with little people or short residence time and the small room that is not easy to send a fresh air will rely on the natural ventilation to achieve the purpose of the air exchange. From the first level to the ninth level are use of ceiling air conditioning units, fan coil are used the way of downward air supply.Guest Rooms are use the way of Side air supply, the other room to send the wind use the way of downward air supply.
The fresh air unit of first layer is placed in the kitchen of outdoor ，it can maximum reduce the effect of noise, and from the second layer to the ninth floor of fresh air unit is placed in the appropriate room ,
Refrigeration room is located in the ground floor of the west, the choice of a screw chillers in summer for chilled water, chilled water pump selection is a dual-use equipment, cooling water pump of choice is a dual-use equipment, cooling tower are placed on the roof.
Key words：blower fan coil with new wind; Air supply mode; Refrigeration room；Water pump
