摘 要

暖通空調(diào)設(shè)計(jì)主要是對(duì)室內(nèi)熱環(huán)境、空氣品質(zhì)進(jìn)行設(shè)計(jì)，但這必須在充分了解建筑對(duì)暖通空調(diào)的要求和暖通空調(diào)系統(tǒng)及設(shè)備對(duì)建筑及其它設(shè)施的影響的基礎(chǔ)上進(jìn)行設(shè)計(jì)。
該建筑位于西安市，本工程為酒店空調(diào)工程設(shè)計(jì),酒店高約33米，是一座綜合性建筑物,總建筑面積為9120㎡,其中空調(diào)面積為8973㎡。酒店主樓地面10層,其中一層為商鋪，層高為4.5米，二、三層為雅間、多功能廳, 層高為3.2米，其余四到十層為辦公室、標(biāo)準(zhǔn)間，層高為3.2米。
結(jié)合建筑的特點(diǎn)，夏天采用螺桿式冷水機(jī)組作為冷源，冬季采用城市供熱管網(wǎng)通過(guò)換熱器得到熱水，以達(dá)到節(jié)約運(yùn)行成本的目的。對(duì)于雅間、標(biāo)準(zhǔn)間等小空間采用風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)，每層設(shè)有新風(fēng)機(jī)組，可以由同層的新風(fēng)機(jī)組送入室內(nèi)，風(fēng)機(jī)盤管獨(dú)立承擔(dān)室內(nèi)的冷熱負(fù)荷。風(fēng)機(jī)盤管的新風(fēng)供給方式用單設(shè)新風(fēng)系統(tǒng)，獨(dú)立供給室內(nèi)。而對(duì)于多功能廳、商鋪等空間較大、人員較多、溫度和濕度允許值波動(dòng)范圍小的房間，采用全空氣系統(tǒng)。因?yàn)樵摼频攴块g類型繁多，各房間冷熱負(fù)荷并不相同，可以個(gè)房間進(jìn)行個(gè)別的調(diào)節(jié)。本設(shè)計(jì)空調(diào)水系統(tǒng)選擇閉式、豎直異程、水平同程式、雙管制、單級(jí)泵，變流量系統(tǒng)，這種空調(diào)水系統(tǒng)具有結(jié)構(gòu)簡(jiǎn)單，初期投資小，管路不易產(chǎn)生污垢和腐蝕，不需要克服系統(tǒng)靜水壓頭，水泵耗電較小等優(yōu)點(diǎn)。

ABSTRACT


HVAC design is mainly for indoor thermal environment, air quality in design, but construction must be fully aware of the requirements for HVAC and HVAC systems and equipment for construction and other facilities on the basis of design.
The building is located in xi'an.The project is the hotel air-conditioning engineering design .The hotel is a comprehensive building, The total building area is 9120㎡,but the air-conditioning area is 8973㎡.There are 10 floors of the building . The first floor is for shops which height of the first floor is about 4.5meters.Other layers of the building is 3.2 meters hight .The second and third layers is for Blair and the multi-function hall.And the remaining 4-10 layers is for office room and guest room.
Combine the characteristics of the construction .In summer, we use water-cooled chillers as a cold source . In winter,we use hot water pipe network of city as a source . In order to savings the operating cost. For accor 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 fan-coil bears the indoor cooling load . Fan-coil and fresh air independent supply into room. As for the multi-function hall and shops, such as larger room, more staff, allowed temperature and humidity fluctuations in little,if you set the fan-coil water system will use more end equipments, resulting in a waste of investment. So the entire air system to be adopted. Because of the different types of hotel rooms, the room is not the same as hot and cold load can be individual rooms regulation. The design of air conditioning water systems use closed, vertical different way, the level of the same programs, dual control, single-stage pumps, variable flow system. Air-conditioning water system that is simple in structure, the initial investment, not easy to have a pipeline dirt and corrosion, the system does not need to overcome the hydrostatic pressure head, water pumps, small power consumption and so on.
KEY WORDS: air-conditioning systems, cooling load,water System, independent of fresh air system, fan coil
