新型相变蓄能辐射地板系统传热特性实验研究（英文） ExperimentalStudyontheHeatTransferPropertiesoftheNewTypePhaseChangeEnergyStorageRadiantFloorSystem Abstract Radiantfloorheatingisapromisingmethodforindoorspaceheatingduetoitshighefficiencyandcomfort.However,conventionalradiantfloorsystemshaveproblemsintermsofhighconsumptionofenergyandlackofenergystoragecapacity.Inthispaper,anewtypeofphasechangeenergystorageradiantfloorsystemisdevelopedanditsheattransferpropertiesareexperimentallyinvestigated.Theresultsshowthatthesystemhasahighthermalstoragecapacityandcaneffectivelyreducethetemperaturefluctuationandenergyconsumptionoftheindoorspace.Theheattransfercharacteristicsofthesystemareanalyzedandtheinfluencefactorsarediscussed,includingthematerialpropertiesofthefloorpanels,thephasechangematerialsandtheirmeltingtemperatureandlatentheat.Theresearchresultsprovideatheoreticalandpracticalbasisforthedesignandoptimizationofthenewtypephasechangeenergystorageradiantfloorsystem. Keywords:radiantfloorheating,phasechangeenergystorage,heattransfer,experiment 1.Introduction Inrecentyears,radiantfloorheatinghasbecomeincreasinglypopularduetoitshighcomfort,lownoise,andenergyefficiencycomparedtotraditionalheatingmethods.However,conventionalradiantfloorsystemshaveproblemssuchashighenergyconsumptionandunequaltemperaturedistribution.Therefore,researchershavebeenstrivingtodevelopanewtypeofradiantfloorsystemwithahighthermalstoragecapacityandabetterheatdistributionperformance. Phasechangeenergystoragematerialshavebeenwidelyusedinthermalenergystoragesystemsduetotheirhighenergydensityandtemperatureregulationperformance.Thecombinationofphasechangeenergystoragematerialsandradiantfloorheatingcannotonlyreducetheenergyconsumptionofbuildingsbutalsoimproveindoorthermalcomfort.Thephasechangeenergystorageradiantfloorsystemcanabsorbandstoreheatduringthelow-costelectricityperiodandreleaseitduringthehigh-costelectricityperiod,whichcansaveenergyandreducecosts.
