    • PURPOSE:To prevent the condensation of dew in a building by detecting outside air temperature, room temperature and relative temperature in the room, setting an outer-wall heat transmission coefficient, computing dew point temperature, and displaying the difference between the dew point temperature and the surface temperature in the room. CONSTITUTION:The numerical value of a specified outer-wall heat transmission coefficient is set in a setting device 5 beforehand. The detected signals of the outside air temperature and room temperature which are detected with detectors 2 and 3 and the signal of the preset outer-wall heat transmission coefficient are inputted into a processor 6. The temperature of a surface 1a in the room is computed with a circuit. The detected signals of the room temperature and the relative temperature in the room which are detected with the detectors 3 and 4 are inputted into the processor 6, and dew point temperature is computed. The processor 6 further computes the difference between the surface temperature in the room and the dew point temperature, and the result of the computation is displayed on a display part 7. Thus, the condensation of dew on the surface in the room can be found beforehand, and the occurrence of condensation can be prevented.
