【正文】 I 摘 要 本設(shè)計(jì)對象為沈陽慈愛護(hù)理學(xué)院教學(xué)樓通風(fēng)空調(diào)工程設(shè)計(jì)，總建筑面積為，屬于舒適性空調(diào)。建筑主要功能為教學(xué)、辦公以及學(xué)生活動(dòng)。該建筑地上五層，地下一層。其中包含了多種使用功能的房間。其中右側(cè)帶有一個(gè)報(bào)告廳，采用全空氣系統(tǒng)；主體教學(xué)樓，考慮到其使用時(shí)間上的差別，采用風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)；因此本設(shè)計(jì)中只提供風(fēng)機(jī)盤管作為室內(nèi)的冷熱源。風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)中，新風(fēng)機(jī)組將新風(fēng)處理至室內(nèi)狀態(tài)焓值直接送入室內(nèi)，不再另設(shè)空氣處理裝置。建筑消防上對消防樓梯間設(shè)置了火災(zāi)時(shí)加壓送風(fēng)設(shè)備。 地下室為空調(diào)供熱制冷設(shè)備 間以及倉庫間。各風(fēng)管上設(shè)置防火閥門，平時(shí)開啟，著火時(shí)關(guān)閉。空調(diào)水系統(tǒng)采用同程式，采用送回水立管將地下室機(jī)房制得的空調(diào)水送到教室、訓(xùn)練室等區(qū)域。 關(guān)鍵詞： 暖通空調(diào)；舒適性空調(diào)；全空氣系統(tǒng)；風(fēng)機(jī)盤管加新風(fēng)系統(tǒng) II Abstract This is the HAVC design of Shenyang Ciai Nursing College classroom building ventilation and air conditioning and refrigeration engineering, with a total area of , belonging to the fort air condition. The main function of the building for the teaching building totally has five floors, including a basement. The building contains rooms which has variety useｓ and can be used in different time. Which right sides is a lecture hall ， using the allair system。 the main classroom building, Considering the rooms are used in different time, the design chooses . During to its staggered usage, the design only offer fan coil unit as the indoor heat and cold source. According to the system, Fresh air handling units are fresh air to indoor State enthalpies value directly into the Interior, not adding any other air handling devices. According to the structural fire protection, Pressurized air supply equipment are set in fire fighting stairs and elevator lobby in case of fire. Fire shutter parts of the mechanical exhaust. Basement for air conditioning heating and cooling devices. Each duct set fire valve, normally open, turn off fire. The air conditioning water system uses the same program, the area returned to the water riser to the basement room in the system of airconditioning water to the classroom forum. Key words: HAVC； fort air conditioning； allair system III 目錄 摘要 ............................................................................................................................................
