- 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．
