Abstract: A ventilation system including a ventilator and a processor. The ventilator includes a housing, first intake, second intake, first outlet, second outlet, dampers, first air blower, second air blower, total heat exchanger, and heat exchanger. The processor is configured to change the air flow path of air flowing through the housing from an intake flow path and discharge flow path while in a ventilation mode to a heat exchanger cleaning mode or a total heat exchanger drying mode, in which air in the room flows into the housing through the first outlet, passes through the heat exchanger and then the total heat exchanger, and is discharged to the space outside the room through the second outlet.

Abstract: The humidifier includes a humidifying member, a storage water tank, a circulating water tank, a residual water tank, a supply pump configured to supply water accommodated in the storage water tank to the circulating water tank, a circulating pump configured to supply water accommodated in the circulating water tank to the humidifying member. A fan configured to blow air toward the humidifying member and thereby cause water evaporated to be discharged outside the humidifier, an internal pipe configured to form a flow passage through which water not evaporated by the humidifying member is recovered to the circulating water tank, a drainage member configured to selectively discharge water accommodated in the circulating water tank to the residual water tank, and a controller configured to operate the humidifier in humidity mode based on the water level in the storage water tank.

Abstract: A humidifier includes a storage water tank configured to accommodate a predetermined amount of water; a circulation water tank having a smaller capacity than the storage water tank and including a circulation low water level sensor; a supply pump configured to supply water from the storage water tank to the circulation water tank; a circulation pump configured to supply water from the circulation water tank to a humidifying member; a residual water tank configured to accommodate water discharged from the circulation water tank; a drainage member disposed between the circulation water tank and the residual water tank selectively to discharge water from the circulation water tank to the residual water tank and a processor configured to control the drainage member to discharge water from the circulation water tank to the residual water tank when a low water level signal is received from the circulation low water level sensor.
