PURPOSE: A device for preventing condensation in an enclosure and a condensation preventing method are provided to accurately determine whether a condition for the occurrence of condensation is met through the temperature, humidity, and surface temperature of the inside of an enclosure measured in real time. CONSTITUTION: A device for preventing condensation in an enclosure includes an information collection unit(100), a first wired/wireless transmission unit(200), a surface temperature measurement unit(300), a second wired/wireless transmission unit(400), a heating unit(500), and a microcomputer(600). The information collection unit measures the temperature and relative humidity of the inside of an enclosure(A). The first wired/wireless transmission unit transmits values measured by the information collection unit to the microcomputer. The surface temperature measurement unit measures the temperature of the inner surface of the enclosure in real time. The second wired/wireless transmission unit transmits the inner surface temperature of the enclosure to the microcomputer. The microcomputer receives dry-bulb temperature and wet-bulb temperature of the inside of the enclosure and calculates relative humidity and calculates a dew point of the air in the enclosure. The microcomputer compares the dew point and the surface temperature, and actuates the heating unit in case the dew point is higher than the surface temperature, and stops the heating unit in the opposite case. |
