PURPOSE: To provide an electronic apparatus system having high reliability by preventing vapor condensation in an electronic apparatus housing. CONSTITUTION: An electronic apparatus contains a board 1 for placing heat generating semiconductor components 1, a blower 3, etc., and comprises a humidity detector 11 for detecting the relative humidity and a dew point temperature of cooling air fed into the housing of the apparatus 10 via an opening 14, a surface temperature detector 12 and inner temperature detector 13 for detecting the surface and the interior temperatures of the component, and dehumidifying and heating means having a heat pump 15 and an outdoor unit 16. Further, the apparatus comprises a controller 14 for so controlling the dehumidifying and heating means that the relative humidity becomes less than 100% and the dew point temperature becomes a surface temperature or higher. |
