Overview
Thedesignandmanufactureofcomputershasalong-standingtendencytoignoresafety,health,energysavingandlowpollution.Sincethe1990s,duetoofficepollutioncausedbycomputersandtheemergenceofcomputersyndromesforoperators,therelationshipbetweencomputersandhealth,andcomputersandtheecologicalenvironmenthasbeenconcernedandvaluedbypeople,especiallyinthemoderneraofenergyshortages.WithenvironmentalprotectionIncreasedawareness.Thedevelopmentofagreencomputerisontheagenda.
Comparedwithordinarycomputers,greencomputershavethefollowingcharacteristics:1.Thepowersupplyofthehostisreducedfrom5Vto3.3V.2.Apowermanagementchipwithpausefunctionisaddedtomakethedisplayandtheharddiskseparatepowersupply.Withthisfunction,thepowerconsumptionofthecomputeris120-130Wwhenitisworking,andthepowerconsumptionisreducedto30-40Wwhenitisnotworking.3.Useenergy-savingflat-paneldisplaysthatcanpreventelectromagneticradiation.4.Thechassisofthehostisshieldedbyametalplatetopreventradiationfromescapingfromthesystem.
Followingtheseprinciples,theUSEnvironmentalProtectionAgencytooktheleadinproposingthe"EnergyStar"plan.Thisplanrequiresthatthepowerconsumptionofeachpersonalcomputerbereducedfrom150to300Wto30to50W.Computersthatmeetthisstandardwillbeallowedtobearthe"EnergyStar"logo.Drivenbythe"EnergyStar"program,somewell-knowncomputermanufacturersintheUnitedStateshavesuccessivelyintroducedgreencomputers.
Keypoints
Greencomputersgenerallyhavethefollowingpoints:
①Intheprocessofmanufacturingthemotherboard,useafluorine-freesolventtocleanit.Intheproductionofthemotherboard,thereisacleaningprocess.Generally,fluorineandchlorinecompoundsareoftenused,buttheywilldestroytheearth'sozonelayerandcausegreatpollutionhazardstohumans.Therefore,fromtheperspectiveofenvironmentalprotection,itisbestnottouseCFC-containingthingsinproduction.
②Trytousecomputerpartsthatareeasytorecycle.Duetotherapidreplacementofcomputers,partsthatweredifficulttorecycleinpreviouscomputerscanonlybediscardedintheend,resultinginmoreindustrialwaste.Ifsomeparts,especiallythechassis,powersupply,etc.,aredesignedtofacilitaterecycling,thesedrawbackscanbereduced.
