cop目录概念示例定义计算公式影响因素俚语copCOP的其他英文缩写概念COP(CoefficientOfPerformance),即能量与热量之间的转换比率,简称能效比。编辑本段示例单位1的能量,转换为单位0.5的热量,即COP为0.5。编辑本段定义COP值在ARI标准中,关于冬夏季循环效率提出了以下定义:在冬季供热时,制热量(W)与输入功率(W)的比率定义为热泵的循环性能系数COP(coefficientofperformance,W/W);在夏季制冷时,制冷量(W或Btu/h)与输入功率(W)的比率定义为热泵的能效比EER(energyefficiencyration,W/W或Btu/W.h)为不引起歧义,我们将冬季热泵循环性能系数和夏季热泵的能效比表达形式均采用COP(能效比)表示。编辑本段计算公式其计算公式为:εs=Q0/Ne=Q0/N0·ηs=ε0·ηs。Q0:制冷系统需要的制冷量(或制热量)N0:制冷压缩机的理论功率Ne:轴功率ε0:是理论制冷系数(制热系数)ηs:是总效率(绝热效率)COP值(制冷效率)实际就是热泵系统所能实现的制冷量(制热量)和输入功率的比值,在相同的工况下,其比值越大说明这个热泵系统的效率越高越节能;因此在作制冷系统COP值比较之前,首先要确定各个热泵系统是否在相同的工况之下,然后再进行计算比较。编辑本段影响因素影响机组的COP的因素有以下几点:a、压缩机的性能系数b、热泵机组的系统匹配性:(所谓系统匹配是指:压缩机、冷凝器、蒸发器、节流机构和自控系统的匹配性能。)COP:Commonon-chipprocessor标准片上处理器编辑本段俚语cop学英语的人都知道police是警察的意思,可在美国人们说警察普遍用cop这个词。对英文有些研究的人会说,cop是police的俚语,不是警察的正式用语。那可真是太学究了,因为现在连美国总统、美国国会说警察也常常用cop这个词。其实cop和police或“原指警察制服上的铜扣子,慢慢人们就以扣子代警察了”都没什么关系,但是cop可以说是从copper而来的。根据下面的英文,我们可以看到cop是1700左右进入英语词汇(原本属于法语中的caper及后来的拉丁语capere,其实是今天capture的意思),是“抓捕、抓获”的意思。1846年,有报刊在cop后面加上了“er”的后缀,表示“抓捕或逮捕犯罪的人”。在1859年,cop作为copper的缩写开始流行起来。编辑本段COP的其他英文缩写(AcronymDefinition只取首字母的缩写词定义):COPConstableOnPatrolCOPCalgaryOlympicParkCOPCanadaOlympicParkCOPCarOperatingPanel(elevators)COPCargooilpump(tanker)CoPCarouselofProgress(Disneyattraction)COPCarryOverParts(automotive)COPCashOperatingProfitCOPCenterofPressureCOPCenteronPhilanthropyCOPCentralOregon&Pacific(railroad)COPCertificateofParticipationCOPCertificationofProcessCOPCertifiedOutsourcingProfessional(InternationalAssociationofOutsourcingProfessionals)COPCessationofProduction(oil)CoPChainsofPromathia(gaming)COPChangeOfPlanCOPChangeofPlea(courtterm)COPChangeoverPointCOPCharacterOrientedProtocolCOPChiefOfPoliceCOPCholesterolOxidationProductCOPCircleofProtectionCOPCircleofProtection(Magic;TheGathering)COPCitizenObserverPatrol(Florida)COPCitizensOnPatrolCOPClassofPropertyCOPCleanOutofPlaceCOPCloseObservationPatrolCOPCloseofPlayCOPCo-OrbitingPlatformCOPCo-ProcessorCOPCoalitionforOutsourcingandPrivatizationCOPCoast-OutPointCOPCoastalOceanProgramCOPCodeofPracticeCOPCodeofProcedureCOPCoefficientOfPerformanceCOPCoilonPlug(automotiveignition)COPCol·lectiuOllaaPressió(Catalancountries)COPColegiodeObstetricesdelPerúCOPColegiodeOdontólogosdelPerúCOPCollectiveofPopularOrganizations(DominicanRepublic)COPCollegeofPharmacy(XavierUniversityofLouisiana)COPCollegeofthePacific(UniversityofthePacific;Stockton,CA)COPColloidOsmoticPressure胶体渗透压COPColombianPeso(ISOcurrencycode)COPColumbusOutdoorsPursuitsCOPCombatOutpostCOPCommandObservationPostCOPCommandOperatingProgramCOPCommandOperationProcedureCOPCommitmentandObligationPlanCOPCommitment,ObligationandProcurementCOPCommitteeofPrincipalsCOPCommonOn-ChipProcessorCOPCommonOperatingPictureCOPCommonOperationalPictureCOPCommunicationOrderProcessCOPCommunicationOutputPrinterCOPCommunityofPracticeCOPCommunityOrientedPolicingCOPCommunityOutreachProgramCOPCompanyOftheParacleteCOPComponentObsolescenceProgramCOPComputerOperatingProperlyCOPComputerOperationsParametersCOPComputerOptimizationPackageCOPConceptofOperationCOPConditionsofParticipation(healthcare)COPConferenceofPartiesCOPConferenceofPresidentsCOPConferenceoftheParties(UNFCCC)COPConferenciadelasPartes(French)COPConfigurationOverhaulPlanningCOPConformityofProductCOPConocoPhillips(stocksymbol)COPConsistentOperatingPictureCOPConstrainedOptimizationProblemCOPConstraintOptimizationProblemCOPContactableOffPremisesCOPContaminanteOrgánicoPersistente(persistentorganicpollutant)COPContingencyOperationsPlanCOPContingencyOperationsProcedureCOPContinuationOfPayCOPContinuityofOperationsPlanCOPContractorOwnedPropertyCOPCopperCOPCopulativeCOPCopyCOPCrushofpeople(暗恋的人)COPCopyrightCOPCostofPowerCOPCostofProductCOPCostofProduction(agriculture)COPCostOnlyPaymentCOPCouncilofPresidentsCOPCountryofPayment(airlines)COPCPUOverheatingProtectionCOPCreatingOpportunitiesProgram(Sprint)COPCrossoverProbabilityCOPCryptogenicOrganizingPneumonia(akabronchiolitisobliteransorganizingpneumonia)COPCrystalOriginatedParticlesCOPCurrentOperatingPlanCOPCurrentOperationsPictureCOPCurrentOps(USDoD)COPCustomerOrientedProcess(ISO9001:2000procedures)COPCustomer-OrientedProcessCOPCutOffPostCOPCutaneousOncologyProgramCOPcorporate(company)operationprocedure企业运作程序
