摘 要

本次畢業(yè)設(shè)計(jì)的主要內(nèi)容是對(duì)xx市某綜合大廈進(jìn)行中央空調(diào)系統(tǒng)設(shè)計(jì)。主要內(nèi)容有：系統(tǒng)形式的選擇，對(duì)各層房間的冷負(fù)荷計(jì)算、房間風(fēng)量的計(jì)算和風(fēng)管設(shè)計(jì)計(jì)算；水系統(tǒng)設(shè)計(jì)及相應(yīng)的水力計(jì)算；設(shè)備選型和布置等。該建筑位于保定市，共6層, 建筑總高度25.4m，總建筑面積7254㎡。建筑物地下一層包括車庫(kù)、制冷機(jī)房、水泵房；一、二層為商場(chǎng)，層高為5.0m。三層為KTV歌舞廳，層高為5.0m。四、五、六層位客房，層高為3.4m。在本次設(shè)計(jì)上側(cè)重于中央空調(diào)系統(tǒng)設(shè)計(jì)并且暫不考慮冬季制熱問(wèn)題。根據(jù)房間的功能和設(shè)計(jì)要求，風(fēng)系統(tǒng)分別采用了全空氣系統(tǒng)和獨(dú)立新風(fēng)加風(fēng)機(jī)盤管系統(tǒng)兩種；水系統(tǒng)采用同程式系統(tǒng)。本次設(shè)計(jì)參照了《旅館建筑空調(diào)設(shè)計(jì)》，對(duì)客房部分采用了較高的設(shè)計(jì)標(biāo)準(zhǔn)，采用獨(dú)立新風(fēng)加風(fēng)機(jī)盤管系統(tǒng)。這樣的設(shè)計(jì)能夠滿足房間對(duì)新風(fēng)量的要求，在過(guò)渡季節(jié)可調(diào)節(jié)新風(fēng)量滿足客房室內(nèi)負(fù)荷的需要，從而達(dá)到建筑節(jié)能的目的，減少不必要的能源浪費(fèi)。本次設(shè)計(jì)涉及到空調(diào)系統(tǒng)的劃分，冷負(fù)荷的計(jì)算，房間氣流組織計(jì)算，風(fēng)管的水力計(jì)算及布置；水系統(tǒng)的劃分，水管的水力計(jì)算及水管布置；空調(diào)設(shè)備的選型，冷凍機(jī)房設(shè)計(jì)等。

關(guān)鍵詞：中央空調(diào)系統(tǒng)，負(fù)荷計(jì)算；水力計(jì)算；獨(dú)立新風(fēng)加風(fēng)機(jī)盤管系統(tǒng)；設(shè)備選型；制冷站設(shè)計(jì)










Abstract

The graduation project is the main content of Zhengzhou City, the comprehensive building of a central air-conditioning system design. The main contents are: system form of the option of room on each floor of the cooling load calculation, the calculation of room air flow and wind design calculation; water system design and hydraulic calculation of the corresponding; such as equipment selection and layout. The building is located in Zhengzhou city, a total of 6 layers, building a total height of 25.4m, the total construction area of 7254 ㎡. Buildings including the garage floor, cooling the engine room, pump room; one or two for shopping malls, high layer 5.0m. Three for the KTV song and dance halls, high layer 5.0m. Four, five, six-bit room, storey to 3.4m. In this design focuses on the design of central air-conditioning system and will not consider the issue of winter heating. According to room function and design requirements, the wind systems are a whole new air systems and independent wind plus two fan-coil system; water system with the programming system. The design is based on "high-rise hotel central air-conditioning Design Manual", part of the room using a high design standards, the use of an independent air system. This design can meet the requirements of the room on the volume of outdoor air in the transitional season of fresh air adjustable so as to achieve the purpose of building energy efficiency, reduce unnecessary waste of energy. The design involves the division of air-conditioning systems, cooling load calculations, calculation of room air distribution, duct of the hydraulic calculation and layout; the division of water systems, water mains and pipes of the hydraulic calculation layout; the selection of air-conditioning, refrigeration room design


Key words:
central air-conditioning system; load calculation; hydraulic calculation; independent increase fresh air and fan coil system; equipment selection; refrigeration station design.
