Claims

[Scope of utility model registration request]

A ventilation device that replaces air in the interior space with outside air, a humidity sensor and a temperature sensor provided at appropriate positions within the interior space, and a wall temperature sensor provided at appropriate locations on the wall surface of the interior space. dew point temperature calculation means for calculating the dew point temperature in the interior space based on signals from the humidity sensor and the temperature sensor; and a wall surface detected by the calculated value of the dew point temperature calculation means and the wall surface temperature sensor. a dew condensation determining means for determining condensation or the risk of condensation in the internal space by comparing the temperature with the temperature; and a temperature detected by the temperature sensor and a set temperature, and a wall temperature detected by the wall temperature sensor and the set wall temperature. a high temperature determination means that compares and determines that the temperature of the internal space is equal to or higher than a set temperature and that the wall surface temperature is also equal to or higher than the set wall surface temperature; and a determination result of the high temperature determination means and a determination result of the dew condensation determination means. Based on the above, the ventilation device is operated when the temperature in the interior space is equal to or higher than the set temperature and the wall surface temperature is also equal to or higher than the set wall surface temperature, and when there is condensation or a risk of condensation on the wall surface of the interior space, A ventilation operation control device characterized by comprising a control means for disabling the ventilation device in other cases.
