Title:
DEFOGGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065133
Kind Code:
A1
Abstract:
Provided is a defogging device capable of further reducing the consumption of air conditioning energy. To this end, this defogging device (100) is provided with a temperature sensor (1), an infrared sensor (2), a surface temperature measuring part (3), a humidity sensor (4), a dew-point temperature measuring part (5), and a fogging dew-condensation determining part (6). When the defogging device (100) is instructed to perform a measurement, the temperature is measured by a temperature sensor (1). Furthermore, the temperature of a glass surface is measured by the surface temperature measuring part (3) on the basis of the output of the infrared sensor (2) and the output of the temperature sensor (1) by performing an infrared sensor (2) measurement, and the dew-point temperature is measured by the dew-point temperature measuring part (5) according to the output of the humidity sensor (4) and the output of the temperature sensor (1) by performing a temperature sensor (2) measurement. Finally, the glass surface temperature and dew-point temperature are compared by the fogging dew-condensation determining part (6) to determine whether fogging or dew condensation occurs.
