Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation device having a condensation prevention function and a control method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation apparatus having a dew condensation prevention function and a control method thereof, and more particularly, to a ventilation apparatus having a dew condensation prevention function capable of preventing condensation from occurring inside a ventilation apparatus, .

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.

A room temperature sensor 140 for measuring a temperature of the room air; The control unit 100 controls the air supply fan 25 and the air blowing fan 45 in the case where the temperature difference measured by the indoor temperature sensor 140 and the outdoor temperature sensor 110 is greater than the set temperature difference, And may be operated in the condensation prevention mode.

The outdoor temperature sensor 110 may be provided in the first feed chamber 10.

The first exhaust chamber 30 is provided with a humidity sensor 130 for sensing the humidity of the room air. When the humidity of the room air detected by the humidity sensor 130 exceeds the set humidity, The control unit 100 may operate the condensation prevention operation.

A control method for a ventilation system having a dew condensation prevention function according to the present invention is a control method for a ventilation system having a dew condensation prevention function, comprising a first air supply room (10) into which outdoor air flows, a second air supply unit A first exhaust chamber 30 into which room air flows, a second exhaust chamber 40 through which indoor air passed through the first exhaust chamber 30 is discharged to the outside, An exhaust heat exchanger (50) for performing heat exchange between indoor air introduced into the second exhaust chamber (40) and outdoor air introduced from the first air supply room (10) to the second air supply room (20) A method for controlling a ventilating apparatus including an air supply blower (25) for forcedly sucking air into the room, and an air blowing fan (45) for forcibly discharging the indoor air to the outside, comprising the steps of: a) And determines whether the stop time has exceeded the set time step; b) When the stop time exceeds the set time, the controller 100 drives the air supply fan 25 and the air blower 45 to operate in the dew condensation prevention mode.

The outdoor air temperature sensor 110 senses the temperature of the outdoor air to determine whether the temperature of the outdoor air is lower than a predetermined temperature. When the temperature of the outdoor air is lower than the predetermined temperature, the controller 100 determines that the air- And the exhaust blower 45 to operate in the condensation prevention mode.

The outdoor temperature sensor 110 and the indoor temperature sensor 140 respectively detect the temperature of the outdoor air and the indoor air temperature to determine whether the temperature difference between the outdoor air and the indoor air is greater than the set temperature difference, If the temperature difference between the outdoor air and the indoor air is larger than the set temperature difference, the controller 100 may operate the air supply fan 25 and the air blower 45 to operate in the condensation prevention mode.

2 is a view showing a control configuration of a ventilator according to the present invention;

4 is a flowchart showing a control method of a ventilator according to another embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The configuration of the ventilator according to the present invention will be described with reference to Figs. 1 and 2. Fig.

The ventilator 1 according to the present invention includes a first air supply room 10 through which outdoor air flows through an outdoor air intake port 12 and outdoor air passed through the first air supply room 10 through an outdoor air outlet A first exhaust chamber 30 through which indoor air is sucked through an indoor air intake port 32, a second exhaust chamber 30 through which indoor air is introduced through the first exhaust chamber 30, A second exhaust chamber 40 for exhausting the air from the first exhaust chamber 30 to the outside through the room air outlet 42 and a second exhaust chamber 40 for exhausting the room air introduced into the second exhaust chamber 40 from the first exhaust chamber 30, (25) for forcedly sucking the outdoor air into the room, and an indoor heat exchanger (25) for forcibly discharging the indoor air to the outside A timer 120 for measuring a stopping time from the operation stop point of the ventilator 1, a timer 120 for measuring the stopping time of the ventilator 1, If the still from the measured time exceeds a set time is made by a control unit 100 that drives the above-class appointed blower 25 and exhaust blower 45 for driving to the anti-condensation mode.

A filter (not shown) for purifying the outdoor air flowing into the total enthalpy heat exchanger 50 from the first air supply room 10 may be provided on the side of the total enthalpy heat exchanger 50.

The timer 120 measures the elapsed time (stopping time) from the time when the ventilator 1 stops operating, and the control unit 100 determines that the stopping time is a set time (for example, 8 hours) If the stop time exceeds the set time and the outdoor air temperature is lower than the set temperature or the temperature difference between the outdoor air and the indoor air is larger than the set temperature difference as described later, So that the occurrence of condensation can be prevented. Here, the set time is a predetermined time set in the control unit 100, and a point at which condensation is expected to occur after the shutdown of the ventilator 1 is predicted by considering the outdoor air temperature or the temperature difference between the outdoor air and the indoor air, It can be measured and set in advance.

The first air supply room 10 may further include an outdoor temperature sensor 110. Condensation occurring inside the ventilator (1) occurs mainly in the winter season where the indoor temperature is high and the outdoor temperature is low. Therefore, when the stop time measured by the timer 120 exceeds the preset time and the temperature of the outdoor air measured by the outdoor temperature sensor 110 is lower than the set temperature, the controller 100 controls the supply fan 25 and the exhaust blower 45 to operate in the dew condensation prevention mode.

In this case, the first air supply chamber (10) is provided with an electric damper (not shown) that opens when the outside air is introduced. The temperature of the space in which the outdoor temperature sensor 110 is installed due to the electric damper is somewhat higher than the outdoor temperature. Therefore, when the condensation prevention mode operation is performed from the temperature information measured by the outdoor temperature detection sensor 110, the condensation prevention mode operation is started at a somewhat higher temperature than the actual outdoor temperature, so that the occurrence of condensation can be minimized.

In addition, since the place where the condensation occurs is the inside of the ventilator (1), it is preferable that the condensation prevention mode operation is started by measuring the outdoor temperature inside the ventilator (1) This is possible. In other words, if the outdoor temperature sensor 110 directly senses the outdoor temperature, the condensation prevention mode operation can be performed even under the condition that no condensation will occur. However, the outdoor temperature inside the ventilator 1 is measured The condensation prevention mode operation is performed by the actual condensation generating condition, so that the efficient operation of the ventilation apparatus 1 is possible.

The first exhaust chamber 30 may further include a humidity sensor 130 for sensing the humidity of the room air. The first exhaust chamber (30) is a place where room air is introduced and is most likely to cause condensation inside the ventilator (1). Accordingly, the humidity sensor 130 senses the humidity of the first exhaust chamber 30, and the controller 100 operates in the condensation prevention mode when the sensed humidity exceeds the set humidity .

Meanwhile, an indoor temperature sensor 140 for measuring the temperature of the indoor air may be provided. Since condensation occurs mainly when the outdoor temperature is low, it is possible to operate in the condensation prevention mode by measuring only the outdoor temperature. However, even if there is a large difference between the indoor temperature and the outdoor temperature, the possibility of condensation is high.

The control unit 100 controls the air supply fan 25 and the air blowing fan 45 when the temperature difference measured by the indoor temperature sensor 140 and the outdoor temperature sensor 110 is greater than the set temperature difference, To operate in the condensation prevention mode.

A control method of the ventilator according to the present invention will be described with reference to FIG.

In step S10, the control unit 10 determines whether the ventilator 1 is in operation or in a stopped state. In this case, the timer 120 measures the elapsed time from when the operation of the ventilator 1 is stopped.

As a result of the determination, if the ventilator 1 is not in the stop state, the process proceeds to step S10, and if the ventilator 1 is in the stopped state, step S11 is performed.

It is determined whether or not the stop time of the ventilator 1 exceeds the set time in step S11.

As a result of the determination, if the stop time does not exceed the set time, the timer 120 continues the stop time measurement, and if the stop time exceeds the set time, the step S12 is performed.

The outdoor temperature measured by the outdoor temperature sensor 110 is compared with the set temperature set in the controller 100 in step S12. If it is determined that the outdoor temperature is equal to or lower than the set temperature, the process proceeds to step S14 to enter the condensation prevention mode. Otherwise, the process proceeds to step S13.

In step S13, if the outdoor temperature is higher than the set temperature, it is determined that the condensation occurrence condition has not been formed yet and the operation waits until the additional monitoring time (for example, one hour) elapses. Compare the temperature again.

When the condensation prevention mode is started in step S14, steps S15 to S17 are performed to control the condensation prevention mode to be rotated to the minimum number of revolutions of the blower.

In the general ventilation mode other than the dew condensation prevention mode in the ventilator 1, the number of revolutions of the air supply blower 25 and the exhaust air blower 45 can be operated in three modes. In the strong mode, the number of revolutions of the blowers 25 and 45 is high, and in the weak mode, the number of revolutions of the blowers 25 and 45 is low. It is also possible for the user to directly set the number of revolutions of the air supply fan 25 and the air discharge fan 45 in the condensation prevention mode.

In step S15, the number of revolutions of the blowers 25 and 45 set in the weak mode is compared with the number of revolutions of the blowers 25 and 45 set by the user, and it is determined whether or not the weak mode revolution number is larger than the set revolution number.

If it is determined that the weak mode revolution number is larger than the set revolution speed, the blower 25, 45 is rotated at the weak mode revolution at step S16. Otherwise, the blower 25, 45 is rotated at the set revolution speed set by the user at step S17 . As described above, by optimally controlling the dew condensation prevention mode operation by rotating the blowers 25 and 45 at the minimum number of revolutions in the dew condensation prevention mode.

In this case, the air blower for blower 45 may be operated more strongly (at a high rotational speed) than the air blower 25 for air conding mode operation. Condensation mainly occurs in the exhaust flow path, so that condensation can be effectively prevented by more strongly operating the exhaust blower 45, and unnecessary operation can be reduced by driving the air supply fan 25 lightly.

When the condensation prevention mode is operated by the rotation of the blowers 25 and 45 at the minimum number of revolutions as described above, the condensation prevention operation is performed for the condensation prevention operation time (for example, 15 minutes) set in advance in step S18.

4 is a flowchart illustrating a control method of a ventilator according to another embodiment of the present invention.

All steps in this embodiment are the same as the embodiment in Fig. 3, only in step S12.

In step S12 of the present embodiment, the outdoor air temperature measured by the outdoor temperature sensor 110 and the indoor air temperature measured by the indoor temperature sensor 140 are respectively sensed, and the temperature of the outdoor air and the indoor air It is judged whether or not the difference is larger than the temperature difference set in the control section 100.

If it is determined that the temperature difference between the outdoor air and the indoor air is larger than the set temperature difference, the process proceeds to step S14 to enter the condensation prevention mode, otherwise, the process proceeds to step S13.

The remaining control steps are the same as those described with reference to FIG. 3, and thus the description thereof will be omitted.

As described above, the present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the scope of the present invention as defined in the appended claims. And such modifications are within the scope of the present invention.
