Description
BACKGROUND OF THE
In general households and offices, there is installed a cooling and heating device to perform indoor cooling and heating according to the seasonal changes. Such a cooling and heating device includes an air conditioner for cooling and heating the indoor air by cooling and heating the indoor air , And boilers.
Since the indoor air such as a general home and office where the air conditioner and the heating device are installed is maintained in a hermetically closed state in order to improve the cooling and heating efficiency, Odor is generated or foreign matter such as dust becomes floating. Accordingly, the room air is ventilated every predetermined time to remove the odor or dust from the room. It is necessary to ventilate the contaminated room air to the outside while maintaining the room temperature, and to ventilate the fresh outdoor air to the room Device is used.
The conventional ventilating apparatus includes a first air supply room into which outdoor air flows, a second air supply room that supplies outdoor air via the first air supply room to the room, a first exhaust chamber into which room air flows, A second exhaust chamber for exhausting the indoor air via the room to the outside, heat exchange is performed between the indoor air flowing into the second exhaust chamber from the first exhaust chamber and the outdoor air flowing into the second air supply chamber from the first feed chamber An exhaust heat exchanger, an air supply blower for forcedly drawing the outdoor air into the room, and an air blower for forcibly discharging the room air outdoors.
Generally, when the outside wall is installed in an insulated space in an apartment or a building, condensation may be minimized inside the ventilation unit. However, when the outside wall of the building is installed in an unheated space, Condensation occurs in the inside of the ventilation apparatus due to a condition substantially similar to that of the outdoor space.
That is, when the temperature of outdoor air is low as in winter, the temperature of the space where the ventilator is installed is lowered. If the ventilator is not used for a long time, the temperature and humidity of the inside of the ventilator Condensation occurs in the first exhaust chamber where high indoor air flows).
As a conventional technique for solving such a problem, Korean Patent No. 10-1498572 entitled "Ventilation System for Moisture Removal" is disclosed.
In the ventilation system disclosed in Korean Patent No. 10-1498572, indoor air is sucked through an air duct for preventing condensation when the humidity measured by the humidity sensor exceeds a predetermined reference value.
However, when condensation prevention operation is performed by measuring only the humidity, when the humidity is excessive as in the case of the rainy season, even if condensation does not occur, the condensation prevention operation can be started and the ventilation apparatus can be operated unnecessarily.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a ventilation system which can extend the service life of a ventilation apparatus by preventing a dew condensation operation only when the ventilation apparatus is not operated for a predetermined time, And an object of the present invention is to provide a ventilation device having a dew condensation preventing function capable of providing an indoor environment and capable of optimizing operating conditions and a control method thereof.
According to an aspect of the present invention, there is provided a ventilation system having a dew condensation prevention function, comprising: a first air supply room (10) through which outdoor air flows; outdoor air passing through the first air supply room (10) A second exhaust chamber (40) for discharging indoor air passed through the first exhaust chamber (30) to the outside, a second exhaust chamber The total

According to the present invention, when the ventilator is stopped for a predetermined time or more, the dew condensation mode operation is performed to prevent the generation of mold and the like, thereby providing a comfortable indoor environment.
The condensation prevention mode operation is performed only when the stop time of the ventilation device exceeds the set time, thereby preventing unnecessary operation of the ventilation device and extending the service life of the ventilation device.
Further, in the condensation prevention mode operation, the exhaust blower is operated more strongly than the blower for the air supply, thereby preventing condensation from occurring in the exhaust passage having a high possibility of condensation, and reducing the number of rotations of the air supply fan So that unnecessary operation of the ventilation device can be reduced.
In addition, it is possible to optimize the control of the dew condensation prevention mode operation by minimizing the flow rate of the blower for air supply and blower for air discharge in the condensation prevention mode operation.
