Abstract (en)
[origin: EP0866285A2] A ventilation device consists of a fan (1) and a distribution pipe (3) with air outlets (11) and temperature sensors (9) assigned to it to measure the room and wall surface temperatures. With a low temperature difference, the fan is automatically switched on by the control electronics (5). The switch-on point for the temperature difference is adjusted by a potentiometer (9). The formation of condensate is prevented as a result of this consequent forced ventilation. The critical dew point is indicated by the LED (7). The temperature sensors preferably consist of NTC resistances. The fan consists of a noise-free small radial fan. The ventilation device consists of a complete unit.
