- Abstract:
-
A solar collectorsystem experimental platformwasbuiltand the experimental wasresearched to get the thermal characteristics of this collector underthe three air flow volumes of0.94,1.41,1.87 m3/h.The collector plate modelwasbuilt by theCFD software,and the simulationwasresearched to get the thermalperformance parameterswhenthe solar radiationwaswithin the range of300 W/m2 to 700 W/m2and the ambient temperature wasbetween6℃and 10 oC.The results demonstrated that the increase of air temperature were respectively 22.45,17.57,14.37 oC,andthe heat collector efficiencywasrespectively 38.56%,45.13%,49.06%underthevolume of0.94,1.41,1.87 m3/h.Thedifferent kindsofconditions’optimalvolumewas got accordingto the simulation values of corrsponding thermal performance parametres,which was to provide the reference data for the selection of operation volume in the solar collector’S practical engineering.
