The project is the multiple–use building airconditioning engineering design .The building is a prehensive building, The total building area is 11020 ㎡ ,but the airconditioning area is 7461 ㎡ .There are 14 floors of the building. The first floor is for Business hall/restaurant / dietkitchen / Worker activity center which height of the first floor is about meters. Other layers of the building are meters high .The sixth to eleventh layers is for office. And the thirteenth/fourteenth layers are for guest room. The ground floor is for garage /refrigerating station / Electric control room / pump house and so on. The main content of this design includes the load putation, the amount determination of new wind, the air treating processes design, the suppose counts with the putation of air current anization, the equipment shaping, the water power putation of aqueous system and the wind system, the systems control plan and so on. The total cooling load of this design is ,and thermal load is ..In summer, we use steam doubleeffect LiBr absorption chiller unit, whose size is SXZ635DH2 , as a cold source. In winter, we use vapor pipe work of city as a source. We use a steamwater changer named office and the standards room, such as small space we use the fan coil and new wind systems, There is one new air unit each layers so that fresh air can be into the indoor and fancoil bears the indoor cooling load. Fancoil and fresh air independently supply into room. As for the Business hall and restaurant, such as larger room, more staff, the drop ceiling air conditioning unit to be adopted. For the different types of rooms, the room is not the same as hot and cold load can be individual rooms’ regulation. The ventilation of garage is well by bowing in the middle and exhausting besides the wall. Key words： Airconditioning system cooling load water System independent of fresh air system fan coil 目 錄 第 1章 設(shè)計(jì)原始資料 ................................................... 1 建筑概況 ....................................................... 1 主要設(shè)計(jì)參數(shù) ................................................... 1 室外氣象參數(shù) ............................................. 1 室內(nèi)設(shè)計(jì)參數(shù) ............................................. 1 第 2章 空調(diào)負(fù)荷的計(jì)算 ................................................. 3 建筑熱工 ....................................................... 3 夏季空調(diào)冷負(fù)荷的計(jì)算 ........................................... 3 空調(diào)房間的冷負(fù)荷 ......................................... 3 空調(diào)房間冷負(fù)荷具體計(jì)算步驟 ............................... 4 冬季空調(diào)熱負(fù)荷的計(jì)算 ........................................... 7 空調(diào)熱負(fù)荷 ............................................... 7 空調(diào)熱負(fù)荷計(jì)算公式 ....................................... 7 房間散濕量 ..................................................... 8 新風(fēng)負(fù)荷 ........................................................ 9 新風(fēng)量的計(jì)算 ............................................. 9 新風(fēng)負(fù)荷計(jì)算 ............................................. 9 第 3章 空調(diào)系統(tǒng)方案的比較與選擇 ...................................... 10 空調(diào)方案的比較 ................................................ 10 空調(diào)系統(tǒng)方案比較 ........................................ 10 各種空調(diào)系統(tǒng)的適用條件 .................................. 11 空調(diào)方案的選擇 ................................................ 12 第 4章 空調(diào)設(shè)備的選擇 ................................................ 13 冷水機(jī)組的選擇 ................................................ 13 冷卻塔的選擇 .................................................. 13 水泵的選擇 .................................................... 14 冷凍水泵的選擇 .......................................... 14 冷卻水泵的選擇 .......................................... 14 補(bǔ)水泵的選擇 ............................................ 15 風(fēng)機(jī)盤(pán) 管的選擇 ................................................ 15 新風(fēng)機(jī)組的選擇 ................................................ 17 換熱器的選擇 .................................................. 17 膨脹水箱的選擇 ................................................ 17 分集水器的選擇 ................................................ 19 分水器和集水器的構(gòu)造和用途 .............................. 19 分水器和集水器的尺寸 .................................... 19 第 5章 氣流組織 ...................................................... 20 風(fēng)口型式的確定 ................................................ 20 風(fēng)口型式的確定 ................................................ 20 散流器平送氣流組織計(jì)算 ........................................ 20 第 6章 水力計(jì)算 ...................................................... 23 水管水力計(jì)算 .................................................. 23 冷凍水系統(tǒng) .............................................. 23 冷卻水 .................................................. 25 冷凝水系統(tǒng) .............................................. 26 風(fēng)管水力計(jì)算 .............................
