Abstract
A ventilation apparatus includes: a housing including a first inlet through which outside air is sucked, a second inlet through which room air is sucked, a first outlet through which air is supplied to an indoor space, and a second outlet through which air is discharged to an outdoor space; an outside temperature sensor configured to measure a first temperature of the outside air; a room temperature sensor configured to measure a second temperature of the room air; a total heat exchanger configured to perform heat exchange between the outside air and the room air; a first blower communicating with the first outlet; a second blower communicating with the second outlet; and a processor to perform a drying operation for the total heat exchanger by operating at least one of the first blower or the second blower, based on a difference value between the first temperature and the second temperature.
