全空氣系統(tǒng)利用系統(tǒng)提供的空氣來獲得冷卻、預(yù)熱和增濕的能力。除了在確定的工業(yè)系統(tǒng)中，在一般工作區(qū)內(nèi)不需要附加的冷卻和增濕。無論在中央系統(tǒng)還是單獨的區(qū)域，都可以用氣流來加熱。在有些應(yīng)用場合，加熱由一個獨立的加熱系統(tǒng)來完成。術(shù)語“區(qū)域”是指供給或需要單獨的溫度控制調(diào)節(jié)裝置的系統(tǒng)，而“區(qū)域房間”是指一個分開的區(qū)域，可能需要也可能不需要單獨的控制。All-airsystemprovidescompletesensibleandlatentcooling,preheating,andhumidificationcapacityintheairsuppliedbythesystem.Noadditionalcoolingorhumidificationisrequiredatthezone,exceptinthecaseofcertainindustrialsystems.Heatingmaybeaccomplishedbythesomeairstream,eitherinthecentralsystemorataparticularzone.1Insomeapplications,heatingisaccomplishedbyaseparateheatingsystem.Thetermzoneimpliestheprovisionortheneedforseparatethermostaticcontrol,whilethetermroomimpliesapartitionedareathatmayormaynotrequireseparatecontrol.2Text

全空氣系統(tǒng)分為兩類：單管系統(tǒng)，其在串流氣體通道內(nèi)含有主要的加熱和冷卻盤管；就是一個普通的管道分配系統(tǒng)在常溫下為所有終端設(shè)備服務(wù)。雙管系統(tǒng)，其在平行或串聯(lián)平行氣流通道內(nèi)包含主要的加熱和冷卻盤管，這些通道或者（1）具有在終端設(shè)備處混合空氣的獨立的冷熱空氣分配系統(tǒng)，或者（2）具有給每一個區(qū)域單獨輸送空氣的管道，使空氣在主單元混合節(jié)氣閥處混合到所需的溫度。All-airsystemsareclassifiedintwobasiccategories:Single-ductsystems,whichcontainthemainheatingandcoolingcoilsinaseriesflowairpath;acommonductdistributionsystematacommonairtemperaturefeedsallterminalapparatus.Dual-ductsystems,whichcontainthemainheatingandcoolingcoilsinparallelfloworseries-parallelflowairpathswitheither(1)aseparatecoldandwarmairductdistributionsystemthatblendstheairattheterminalapparatus,or(2)aseparatesupplyairducttoeachzonewiththesupplyairblendedtotherequiredtemperatureatthemainunitmixingdampers.Text

全空氣系統(tǒng)適合于許多要求舒適或過程工業(yè)領(lǐng)域的應(yīng)用場合。常用于需要單獨控制多個區(qū)域的建筑物，如辦公樓；學(xué)校和大學(xué)；實驗室；醫(yī)院；商店；旅館等等。全空氣系統(tǒng)實際上還專門用在需要封閉控制溫度和濕度的特殊場合，包括潔凈房間，計算機房，醫(yī)院手術(shù)室，研究與開發(fā)設(shè)備，以及許多工業(yè)制造設(shè)施。All-airsystemsmaybeadaptedtomanyapplicationsforcomfortorprocessworld.Theyareusedinbuildingsthatrequireindividualcontrolofmultiplezones,suchasofficebuildings;schoolsanduniversities;laboratories;hospitals;stores;hotels,etc.3All-airsystemsarealsousedvirtuallyexclusivelyinspecialapplicationsforclosecontroloftemperatureandhumidity,includingcleanrooms,computerrooms,hospitaloperatingrooms,researchanddevelopmentfacilities,aswellasmanyindustrialmanufacturingfacilities.Text

總之，建庫的材料必須符合以下要求。比如：氣密性好、不會散發(fā)氣味、對微生物的活動和濕氣有抵抗性、對機械震動有抗性、防火、當(dāng)庫房內(nèi)的溫度、相對濕度和氣壓變動時，它們的性質(zhì)能保持不變。儲藏室的門應(yīng)是隔熱的.并且，門應(yīng)裝有橡膠封條或使用滑動密封門，從而保證儲藏室的閉合。一般情況，門上還會設(shè)置觀察窗。觀察窗的高度一般高于庫內(nèi)堆積產(chǎn)品的高度。Inallcases,thematerialsofstorageshouldmeetsomerequirementasbelow.Suchas,itisgas-tightness,notgiveoffodors,beresistanttotheactionofmicro-organismsandhumidity,beresistanttomechanicalshock,befire-proof,remaintheirpropertiesduringvariationsontemperature,relativehumidityandpressurewithinthestorage,andsoon.DoorsofCAstorageshouldbeadiabatic.Inaddition,inordertoensureclosure,theyshouldbewithrubbersealandslidinghermeticdoor.Moreover,wecaninstallinspectionwindowsonthewindowsonthedoorsordinarily.Inspectionwindowsplacedatalevelabovethatofthecontentsofthestoremaybemoreuseful.3Text

全空氣系統(tǒng)具有下列優(yōu)點和缺點優(yōu)點：1、主要設(shè)備的重要機械裝置所在場所允許在閑置的區(qū)域內(nèi)進(jìn)行操作和維護(hù)，為過濾設(shè)備、振動和噪音控制、及高質(zhì)量和耐久性設(shè)備的選擇提供最大的選擇范圍。TherearesomeadvantagesanddisadvantagesofAll-AirSystem.Advantages:1、Thecentralmechanicalequipmentroomlocationformajorequipmentallowsoperationandmaintenancetobeperformedinunoccupiedareasandpermitsthemaximumrangeofchoicesoffiltrationequipment,vibrationandnoisecontrol,andtheselectionofhighqualityanddurableequipment.Text

2、在空調(diào)區(qū)域內(nèi)完整沒有管道、電氣設(shè)備、配線、過濾器、及產(chǎn)生振動和噪音的設(shè)備減少了對居住者，家具的危害，同時維修服務(wù)降至最少。3、全空氣系統(tǒng)在室外空氣和“自由”冷卻系統(tǒng)應(yīng)用中，取代機械制冷具有最大的潛力。4、季節(jié)性周期轉(zhuǎn)換很簡單，非常適宜于自動控制。5、在所有操作條件下，分區(qū)性，機動性，濕度控制具有廣泛的選擇范圍，還具有同時加熱和冷卻的性質(zhì)。6、全空氣系統(tǒng)和其它熱回收系統(tǒng)容易合成一體。2、Completeabsencewithintheconditionedareaofpiping,electricalequipment,wiring,filters,andvibrationandnoise-producingequipmentreducespotentialharmtooccupants,furnishings,andprocessesminimizingserviceneeds.3、Thesesystemshavethegreatestpotentialfortheuseofoutsideairand“free”coolingsystemsinplaceofmechanicalrefrigerationforcooling.4、Seasonalchangeoverissimpleandreadilyadaptabletoautomaticcontrol.5、Givesawidechoiceofzoning,flexibility,andhumiditycontrolunderalloperatingconditions,withtheavailabilityofsimultaneousheatingandcooling6、Air-to-airandotherheatrecoverysystemsmaybereadilyincorporated.Text

缺點：1、全空氣系統(tǒng)需要附加的管道布置空間，從而減少了可用空間增加了建筑物的高度。2、根據(jù)布置規(guī)劃圖，管道布置需要的立軸空間要求有較大的樓板層面。3、完成最終設(shè)備要求建筑、機械、結(jié)構(gòu)設(shè)計師的全面合作。4、空氣配平特別是在大型系統(tǒng)中很難實現(xiàn)。Disadvantages:1、Theyrequireadditionalductclearance,whichreducesusablefloorspaceandincreasestheheightofthebuilding.2、Dependingonlayout,verticalshaftspaceisneededfordistributionrequiringlargerfloorplates.43、Theaccessibilityofterminaldevicesrequiresclosecooperationamongarchitectural,mechanical,andstructuraldesigners.4、Airbalancing,particularlyonlargesystems,canbemoredifficult.
