摘要本设计为苏州某宾馆空调系统设计,针对苏州特定的气象条件进行空调系统设 计,设计出符合人员居住的室内环境。
在空调设计中,一层的 KTV 大厅、大堂周边、大会议室、厨房和二层的茶楼大 厅、宴会大厅采用全空气系统一次回风的方案来处理空气。一层和二层的其余房间(包 间、小会议室等)安装风机盘管。每个房间的风机盘管和新风机组由所算出的负荷决 定,风机盘管安装在每个房间的吊顶内。每层楼装有一台新风机组,新风机组产生的 新风通过独立的新风管道送入各个房间,每层的新风负荷由该新风机组承担。84140
本次空调系统设计任务先对各个房间进行负荷计算,包括冷负荷、湿负荷和新风 量,风机盘管和空调机组的选型由房间的所有冷负荷总和来确定,水管和风管的的设 计选型则由风管和水管的水力计算来确定,最终完成苏州宾馆的空调设计。

Abstract The design for a hotel air conditioning system design Suzhou, Suzhou air-conditioning systems designed for specific weather conditions, designed to meet the people working and living in the indoor environment。
In the design of air conditioning, floor KTV hall, surrounding the lobby, large conference room, the kitchen and the second floor of the restaurant hall, banquet hall using a return air programs to deal with the whole air system air。 First and second floors of the rest of the room (private rooms, meeting rooms, etc。) using the fan coil independent air system。 Select the fan coil according to the load of each room and new air handling units, fan coil installed in the ceiling of each room。 Each floor is equipped with a new air handling units, new air unit new wind generated by independent fresh air is piped into each room, each floor of the new wind load borne by the new air unit。
The first air conditioning system design tasks for each room of load calculation, including the selection of cooling load, wet load and fresh air, and air-conditioning fan coil units by the sum of all the cooling load of the room to determine the design of pipes and ducts Selection by wind and water pipes hydraulic calculations to determine the eventual Suzhou hotel air conditioning design。
Keywords:Air conditioning systems; cooling load,; fan coil plus an independent air system;all air system;hydraulic calculation
