摘要:本设计是关于上海市某酒店A区空调系统的设计,该建筑共两层,建筑总面积为3292.48m2,其中空调面积为2037.21m2。首层层高为4.5m,二层为4.2m,建筑总高度8.7m。空调房间的类型主要可以分为用餐大厅、商务中心、大堂、服务台、休息大厅、客房、备餐室、总机房以及零食店和咖啡厅。本次设计使用鸿业暖通空调负荷计算软件9.0对该建筑物内的空调房间区域进行负荷计算,夏季室内总冷负荷为151846W,夏季室内冷负荷指标为124.7W/m2。考虑该建筑为一四星级酒店,从满足顾客舒适度及空调系统运行节能的角度出发,空调系统采用大面积房屋例如大堂休息大厅等使用全空气一次回风系统,因为它的造价低廉维护简单。包房以及服务台等小房间均使用风机盘管加独立新风系统;主要是考虑了其占地面积较小、噪音低和易于控制等优点。空调内区因为全年需要不停的供冷,所以采用全空气一次回风系统,新风跟回风完全混合后经由空气处理机组处理之后直接送入房间。比如面积较大的咖啡厅、用餐大厅、大堂等采用全空气系统,为了能够有效的进行除湿并且满足风量要求,设置方形散流器并且采用平送风的方式。此外,我还简单的对空调系统的防腐保温和消声减以及减震进行了简单的设计。70607

Air Conditioning System Design of A Hotel Area A In Shanghai
Abstract:This design is about an air conditioning system design of a hotel A aera in Shanghai , the hotel is a two-layer building, The construction area are 2859.88 m2, including air conditioning area is 2037.21 m2. First layer upon layer of 4.5 m high, second floors high is 4.2 m, building a total height of 8.7 m. Type of air conditioning room is mainly for the business center,dining hall, lobby, lounge, reception and guest room. Use HONGYE thermal load calculation software 9.0 room area in the building air-conditioning system load calculation, summer indoor total cooling load of 160737 W, winter indoor total heat load of 87575 W, summer indoor cooling load index is 233.9 W/m2, winter indoor heating load index is 178.65 W/m2. Considering the building for a hotel which is four-star, from customer comfort consideration and air conditioning system energy saving point of view, the area that outside the large space air conditioning room like lobby use a return air system, air conditioning terminal use erminal control; Air conditioning area little spaces which are outside rooms adopt fan-coil unit housekeeper independent fresh air systems; Area within the air conditioning because of the year need cooling, using a return air systems, fresh air and return air mixed by air handling unit directly send into the room, duct end adopts terminal. Just like larger area of the front office, dining hall, cafe, etc with full air system, set the diffuser is flat to form, so it can effectively for dehumidification and can reduce the requirement of air volume, for the bedrooms and suites, because the area is much more little, we adopt fan-coil unit plus fresh air system side send airflow organization form, mainly considering the covers an area of small, little noise and easily to control, etc. In addition, I also design insulation of air conditioning system and shock absorption.etc. .
