The present invention relates to a control method for a ventilation device. According to the present invention, the control method for a ventilation device includes: a case; a flow path formed in the case, wherein inner air or outer air flows; a heat exchanger installed in the flow path and partitioning the flow path toward an inlet and an outlet; a temperature sensor installed on the inlet and the outlet, respectively; a humidity sensor installed on the inlet and the outlet, respectively; and an air conditioning unit operating the heat exchanger by an evaporator or a condenser. A moisture amount on the inlet and the outlet is calculated by the temperature sensor and the humidity sensor, and switching of a role of the evaporator and the condenser of the air conditioning unit is determined using the difference of the moisture amount between the inlet and the outlet. According to the present invention, the control method for a ventilation device can actively perform the switching by calculating an evaporated moisture amount or an actually adsorbed moisture amount in first and second outer heat exchangers so the control method for a ventilation device can reduce power consumption. |
