大多家用空调有的部件在室内，有的部件在室外，但是又都不是全部在室内或全部在室外。外部部件主要受到天气和外部环境的影响，室内部件主要受到灰尘影响。Mostroomairconditionersareeitherexposedtoindoororoutdoorconditions,butnotboth.Foroutsideelements,theyareaffectedbytheweatherorenvironment.Ontheotherhand,thedustexertagreatinfluenceontheinsideelements.Text

空调中的杂质会降低效率和加速外壳腐蚀。有时候，空调会发展到很严重的地步需要彻底清洗。霉菌会在设备单元中滋生，赘生物也会向外壳方向迁移。另外，机器的寿命主要取决于它如何使用。所以，如果家用空调经常清洗的话，压缩机的寿命就会延长。保持空调清洁高效并不费力却能省电，这很值得一做。Debrisintheairconditionercanreduceefficiencyaswellasacceleratecorrosionofthesteelhousing.Sometimesairconditionersappearveryseriousconditionsandneedtobecleanedthoroughly.Moldcandeveloparoundtheunit,orvegetationmaymigratetowardsthehousing.Inaddition，theservicelifeofamachinedependschieflyuponhowitisbeingused.1Well,thelifeofacompressorwillextentwhenroomairconditioneriscleanusually.Keepinganairconditioningunitcleanandefficientcantakealittleextraeffortbutthesavingsinelectricitywillbeworthit.2

保持空调高效运转的两个关键因素是确保室内外盘管的气流量合适且确保盘管干净。盘管洁净传热高效，压缩机运转会减少。清洗过程需要以下工具：真空吸尘器、长柄刷子、抹布、清洗剂、可选择性螺丝刀、新过滤网（可选择）等。Thetwokeyfactorstokeepanairconditionerrunningmostefficientlymakesureithastheproperamountofairflowovertheindoorandoutdoorcoilsandkeepingthecoilsclean.3Cleancoilstotransferheatmoreefficiently,sothecompressormayrunless.Cleanprocessneedsometools,suchasvacuumcleaner,longhandledbrush,rags,detergent,selectionofscrewdrivers,newfilter((optional),etc.Text

首先，空调清洗过程必须切断电源。其次，把前面的格板取下。一般可以直接取下，但是有时候也会有螺丝固定。取下过滤网要么清洗要么更换。如果是一次性的，更换一个新的即可。另外一种类型是塑料结构或泡沫薄片，这一种可以清洗后再使用。清洗时，平置，用清洗剂浸泡或在上面喷洒。然后放在温水中，温水量能淹没滤网即可。浸泡15分钟后取出并用温水漂洗。最后悬挂晾干，这期间可以做后面的工序。Firstofall,airconditionercleaningoperationmustbeshutdown.Secondly,takethefrontgrilloff.Removeddirectly,butsometimestherearescrewsthatholditinplace.Removethefilterandeithercleanitorreplaceit.Ifitisadisposabletype,simplyreplaceitwithanewone.Othertypesaremadeinaplasticframeorfoampiece，whichcanbecleanedandreused.Tocleanareusabletype,layitflatinthesinkandsprinklesurfacewithlaundrydetergent.Thencoverwithwarmwater.Justenoughtothefilterissubmerged.Soakfor15minutesorsoandremovefromwaterandrinsewithwarmwater.Hanguptodrywhileproceedingtonextstep.Text

接下来，用软刷子上下移动清除翅片上的表面灰尘（蒸发器）。不要来回清扫把翅片弄弯，因为翅片很容易损坏。一旦表面灰尘去除后，喷洒一些去脂剂。然后，重复上面的步骤，清洗冷凝器盘管。一般冷凝器翅片都有塑料罩。如果是这样，检查顶部是否可以抬起或打开。如果可以就很容易接触到冷凝器翅片。注意：冷凝器盘管中充满高压制冷剂。Next,removesurfacedustanddirtfromthefins(evaporator)withasoftbrushupanddownmotion.Donotgosidetosideorallowthefinstobebentover，becausetheycanbedamagedeasily.Oncesurfacedirtisremoved,spraywithde-greaser.Then,repeatabovestepforthecondenser(rearfins)coil.Aplasticcowlingusuallysurroundsthecondenserfins.Ifso,checkthetopedgetoseeifitwillliftoropen.Ifitopens，thiswillalloweasieraccesstothecondenserfins.Againusecautionbecausethecondensercoilisalsofilledwithhighpressurerefrigerant.Text

最后，必须确保空调的风扇电机千万不能沾水。当然，清洗电气部件都不能打开其绝缘和保护材料。总之，要所有部件都晾干后才能启动，尤其是风扇电机或电气部件沾水后。Last,airconditionerfanmotorisnotwater,youcanbeassured.Ofcourse,cleaningelectricalpartsyoucannotopentheisolationoftheprotectiveplatestufflike.Overall,letanyunitdrybeforestartingit，especiallyifthereisanychancethatwatergetinthefanmotororonelectricalcomponents.NotestotheTextNotestotheText

1.Inaddition，theservicelifeofamachinedependschieflyuponhowitisbeingused.How引导的从句做介词upon的宾语，theservicelife表示及其或设备的“寿命”，dependupon（on）表示“依靠、凭借”，类似的句子有：

Successdependsonchance.成败在于机遇。NotestotheText这个句子的结构很简单，谓语是willbe，表语是worthit，前面所有的部分Keepinganairconditioningunitcleanandefficientcantakealittleextraeffortbutthesavingsinelectricity都是主语，是主语从句，表示保持空调机清洁高效会费一点额外的力，但是会节电，这很值得一做。2.Keepinganairconditioningunitcleanandefficientcantakealittleextraeffortbutthesavingsinelectricitywillbeworthit.NotestotheTextThetwokeyfactors是主语，tokeepanairconditionerrunningmostefficiently是不定式结构做定语，修饰主语factors，ithastheproperamountofairflowovertheindoorandoutdoorcoilsandkeepingthecoilsclean.是宾语从句，做谓语makesure的宾语。makesure是谓语，表示“确保，保证”，类似的句子有：Beforegoingout,shemadesureallthewindowswereclosed.外出之前，她先查看所有的窗户是否都关好。3.Thetwokeyfactorstokeepanairconditionerrunningmostefficientlymakesureithastheproperamountofairflowovertheindoorandoutdoorcoilsandkeepingthecoilsclean.ExerciseDecidewhetherthefollowingstatementsaretrue(T)orfalse(F)accordingtothetext:1.Th
