山東職業學院初稿畢業設計題目：小型辦公樓空調工程設計系部：土木工程系專業：供熱通風與空調工程技術班級：姓名：學號：指導教師：2014年4月15日摘要本設計是為北京市某辦公樓暖通空調系統設計。本工程為框架結構，共四層，其中地上三層，建筑總面積1000-1200m2。地下一層為車庫。建筑功能為辦公樓，另外還有健身房和衛生室等。本設計結合北京地區的自然條件和《實用供熱通風設計手冊》《空氣調節設計手冊》《民用建筑暖通空調設計技術措施》《采暖通風與空氣調節設計規范》《采暖通風與空氣調節制圖標準》《空調冷負荷計算方法》《空調與制冷技術手冊》對該建筑進行中央空調設計。隨著社會進步，經濟發展，生態環境和能源問題日益突出。人們越來越注意到可持續發展的重要性。中央空調系統是一個龐大復雜的系統，能耗很大，因此節能有很大空間。在進行系統設計過程中，關于系統選擇和設備選型，本設計考慮了節能的要求。還有對于暖通空調系統的設計，每個環節都必須要嚴格按照國家、地區或行業的標準和規范執行，做到精心設計計。前言隨著國民經濟的發展和人們對生活質量要求的日益提高，建筑居住環境的健康和舒適性已經成為當代建筑發展的必然趨勢，能否為現代建筑的特殊要求提供人們滿意的環境和服務，是建筑行業蓬勃發展的重要因素。商業建筑不斷的增多，以及人們對室內空氣的溫濕度、潔凈度和空氣品質問題越來重視。由于能源的緊缺，節能問題越來越引起人們的重視。因此迫切需要為商業建筑物安裝配置節能、健康、舒適的中央空調系統來滿足人們對高生活水平的追求。目前，隨著我國經濟的逐步增長，居住條件日益改善人們對生活環境的舒適性的要求越來越高，對中央空調的需求越來越大，對中央空調節能、舒適、健康更加關注。因此，設計一項節能、舒適。健康的中央空調工程是很有實際意義的。目錄工程概況設計依據主要參數冷負荷計算各房間多聯機室內機的選擇多聯機室外機的選擇全熱交換器的選擇全部材料工程概況（1）本工程為北京市溫泉總部基地，38號樓，地上三層為辦公空間，地下一層為儲藏室、設備用房，建筑高度11.42m，結構形式為框架結構。本建筑主體朝向為南北朝向，體形系數0.43。（2）外墻墻體材料采用250mm，厚自保溫砂加氣混凝土，砌塊墻，梁、柱采用擠塑聚苯板保溫材料。外飾面材料為干掛石材，局部仿石涂料。（3）本工程非采暖空間部位為：各層電梯、地源熱泵機房等部位二、設計依據主要參考資料及文獻1、《實用供熱通風設計手冊》，中國建筑工業出版社2、《空氣調節設計手冊》，中國建筑工業出版社3、《民用建筑暖通空調設計技術措施》，中國建筑工業出版社4、《采暖通風與空氣調節設計規范》，中國計劃出版社5、《采暖通風與空氣調節制圖標準》，中國計劃出版社6、《空調冷負荷計算方法》，中國建筑科學院空調研究所7、《空調與制冷技術手冊》，同濟大學出版社主要參數1、室內人員分布辦公室：0.25人/m22、工作時間：8：00—18:003、照明強度5w/m24、屋頂：結構屬Ⅲ型，k=1.163W/(㎡．K)5、南窗：雙層全部玻璃鋼窗，掛淺色內窗簾6、南墻：紅轉墻，屬Ⅱ型，K=1.55W/(㎡．K)7、室內設計溫度tN=27℃.8、新風量標準：辦公：30m3/h·人9、水源：城市自來水；電源：城市供電；10、新風量標準：執行相關規范冷負荷計算101房間南外墻冷負荷南外墻負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ3534.634.233.933.533.232.932.832.933.133.433.934.4t1,τ－tNF8.37K1.55LQn(q)104999490858177757779839096南玻璃窗傳熱引起冷負荷查表知K=3.01W/(㎡．K)，又查的玻璃窗傳熱系數的修正值對全部玻璃雙層窗應乘1.0的修正系數，最后傳熱系數K=3.01W/(㎡．K)南外窗瞬時傳熱冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ2626.927.929.029.930.831.531.931.630.8t1,τ－tN-1-5.04.63.8F6.48K3.01LQn(q)-19.5-1.9517.553957748896101.4101.49889.774東外墻冷負荷東外墻冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ36.436.035.535.235.035.035.235.636.136.637.137.537.9t1,τ－tN9.49.08.09.610.110.510.9F18.3K1.55LQn(q)267256241233227227233244258273287298310東玻璃窗傳熱引起冷負荷東外窗瞬時傳熱冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ2626.927.929.029.930.831.531.931.630.8t1,τ－tN-1-5.04.63.8F2.16K3.01LQn(q)-6.5-0.65613192529323434333025透過玻璃窗進入日射得熱引起冷負荷本工程所用玻璃為3mm普通平板玻璃鋼窗，查得雙層鋼窗有效面積系數Ca=0.75，古南窗的有效面積F0=19.44*0.75=14.58㎡。查得遮擋系數Cs=0.86，遮陽系數Cn=0.6，于是綜合遮陽系數Cz=Cn*Cs=0.86*0.6=0.516。由手冊可查出維度為40°時南向日射得熱因數最大值Dτ..max=302w/㎡,再有公式LQτ.=F0Cn*CsDτ..maxCL南窗透入日射得熱引起的冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00C10.180.260.400.580.720.840.800.620.450.30Dτ..max302Cz0.516F4.86LQτ13619730343954563663646934124218212176人員散熱引起的負荷人員散熱引起的負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00C10.070.060.530.620.690.740.770.800.830.850.870.890.42LQ122.2419.06168.40197219.23235244.65254263.7270276282.8133LQ2816816816816816816816816816816816816816LQ838835984101310351051106110701080108610921099949（7）照明冷負荷LQ=27.9*5=139.5w最后將前四項逐時冷負荷值并相加，列于下表時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00南外墻負荷104999490858177757779839096南外窗負荷-19.5-1.9517.553957748896101.4101.49889.774東外墻負荷267256241233227227233244258273287298310東外窗負荷-6.5-0.65613192529323434333025南窗日射負荷13619730343954563663646934124218212176人員負荷838835984101310351051106110701080108610921099949總計1319138416461827196820942124198618911815177517281530由上表可知，最大冷負荷出現在13：00時，其值為2124w，再加上照明冷負荷139.5w，則101房間最大冷負荷為2264W。房間102南外墻冷負荷南外墻冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ3534.634.233.933.533.232.932.832.933.133.433.934.4t1,τ－tNF18.18K1.55LQn(q)225.43214.16202.90194.44118.17112.72107.26105.44107.26110.90116.35194.44134.53南外窗傳熱引起冷負荷查表知K=3.01W/(㎡．K)，又查的玻璃窗傳熱系數的修正值對全部玻璃雙層窗應乘1.0的修正系數，最后傳熱系數K=3.01W/(㎡．K)南外窗瞬時傳熱冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ2626.927.929.029.930.831.531.931.630.8t1,τ－tN-1-5.04.63.8F19.44K3.01LQn(q)-58.51-5.8562.66117.02169.68222.34263.30286.70304.41304.41292.55269.15222.34北外墻冷負荷北外墻冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ32.632.332.132.831.631.431.331.431.631.8t1,τ－tN4.8F13.83K1.55LQn(q)120.06113.63109.34124.3598.6294.3492.1990.0590.0592.1992.1998.62102.91北外窗傳熱引起冷負荷查表知K=3.01W/(㎡．K)，又查的玻璃窗傳熱系數的修正值對全部玻璃雙層窗應乘1.0的修正系數，最后傳熱系數K=3.01W/(㎡．K)北外窗瞬時傳熱冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ2626.927.929.029.930.831.531.931.630.8t1,τ－tN-1-5.04.63.8F4.32K3.01LQn(q)-13-1.311.72637.749.458.563.767.667.66559.849.4西外墻冷負荷西外墻冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ38.237.837.336.836.335.935.535.234.934.834.834.935.3t1,τ－tN11.210.87.98.3F33.98K1.55LQn(q)589.89568.84542.50516.17489.83468.76447.70431.89416.09410.83410.83416.09437.16西外窗傳熱引起冷負荷西外窗瞬時傳熱冷負荷時間7：008:009:0010:0011:0012:0013:0014:0015:0016:0017:0018:0019:00t1,τ2626.927.929.029.930.831.531.931.630.8t1,τ－tN-1-5.04.63.8F8.1K3.01LQn(q)-24.38-2.4421.9448.7670.7092.64109.71119.46126.78126.78121.9112.1592.64透過玻璃窗進入日射得熱引起冷負荷本工程所用玻璃為3mm普通平板玻璃鋼窗，查得雙層鋼窗有效面積系數Ca=0.75，古南窗的有效面積F0=19.44*0.75=14.58㎡。查得遮
