ON THE PASSIVE CONDITIONING OF ELECTRONIC CABINETS FOR OUTDOOR INSTALLATION.

Author(s) : GUGLIELMINI G., MILANO G.

Summary

THE OBJECT IS TO MAINTAIN THE INTERNAL TEMPERATURE OF THE CABINET BETWEEN 268 AND 318 K (-5 AND 45 DEG C) WHILE THE EXTERNAL TEMPERATURE VARIES FROM 233 K (-40 DEG C) TO A HOT CLIMATE TEMPERATURE WITH DIRECT SOLAR RADIATION. A COMPUTER CALCULATION WAS DEVELOPED FOR THE STUDY OF THE UNSTEADY THERMAL CONDITIONS OF THESE CABINETS THAT MAY BE EQUIPPED WITH A NATURAL VENTILATION SYSTEM AND THERMAL STORAGE WITH CHANGE OF STATE. RESULTS ARE GIVEN FOR: A CABINET WITH A THERMAL INSULATION EFFICIENT FOR COLD CLIMATE CONDITIONS AND NATURAL VENTILATION OPENING FOR HOT CLIMATE CONDITIONS AND A CABINET WITH PARTIAL INSULATION FOR HOT CLIMATE CONDITIONS AND A RESISTANCE AND THERMAL STORAGE SYSTEM FOR COLD CLIMATE CONDITIONS.
