Abstract：

Based　on　air-enthalpy　method　model　expressed　in　direct　measurement　parameters,　the　uncertainty　of　annual　performance　factor　(APF)　was　evaluated　using　Monte　Carlo　method　combined　with　GUM.　As　air-enthalpy　method　is　nonlinear　and　GUM　is　only　perfectly　suitable　for　the　linear　model,　the　rated　cooling　capacity　uncertainty　and　the　rated　heating　capacity　uncertainty　obtained　using　GUM　were　verified　primarily　by　MCM,　and　the　differences　between　results　obtained　by　GUM　and　MCM　were　lower　than　2‰.　On　this　basis,　uncertainty　results　of　five　different　measurement　conditions　were　given,　and　these　parameters　were　used　as　the　inputs　of　simulation.　The　adaptive　Monte　Carlo　method　simulation　flow　chart　of　APF　was　given,　and　APF　uncertainty　of　an　air　conditioner　was　evaluated,　the　result　was　0.09　kW·h/(kW·h)(k=2).　©　2017,　Acta　Metrologica　Sinica　Press.　All　right　reserved.
