摘要 中文摘要本设计为长沙市某博物馆空调系统工程设计，地上共五层，没有地下室,制冷机房位于二楼楼顶。古墓、字画陈列室、会议、办公室组成，总建筑面积约6800平方米，建筑高度20.4米，属多层建筑。65285
根据各不同功能房间将该集中空调系统分为两种空调送风方式，高大空间如游客活动厅等采用全空气系统，新风直接从室外引进与回风混合（一次回风）后送风；办公室采用了风机盘管加独立新风系统，新风机组从室外引入新风处理到室内空气焓值，风机盘管承担室内冷负荷及部分的新风湿负荷。水系统采用水平闭式双管同程式，冷冻水泵四台、热水水泵四台，两种水泵都是三用一备，补给水泵一台，一用一备，选用三台风冷式热泵机组。

Abstract
The design for the Museum of Changsha city air conditioning systems engineering design, on the ground a total of five, there is no basement, refrigeration room located on the second floor roof. Tombs, paintings showroom, meeting, office, with a total construction area of about 6800 square meters, building height of 20.4 meters, is a multi-storey building.
According to the various function rooms with centralized air conditioning air conditioning system is pided into two ways, large spaces such as halls and other tourist activities all-air systems, the introduction of fresh air directly from the outside mixed with return air (a return air) after the blast; office using a separate fan coil air system, new air from the outdoor unit to the indoor air handling the introduction of new air enthalpy, indoor fan coil cooling load and bear part of the new rheumatism load. Closed water system using horizontal double-tube with the program, four chilled water pumps, water pumps four units, two kinds of pumps are three with a preparation, one supply pumps, one with a prepared, use three air-cooled heat pump units .
Keywords: FCU plus independent air system Full air system
