Abstract

Ventilating system for introducing outdoor air and discharging room air, and method for controlling the same, the ventilating system including a duct for making a room and an outside of the room in communication, a ventilator connected to the duct for discharging room air to an outside of the room, and supplying outdoor air to the room through the duct, a window controller provided to each window for opening/closing the window individually, and a controller for controlling the ventilator and the window controller for ventilating the room. The method for controlling a ventilating system includes the steps of measuring conditions of room air and outdoor air, determining a ventilating method and a ventilating rate according to the measured conditions, and ventilating the room by opening/closing the window automatically, and putting a ventilator into operation according to a result of determination.

Claims

1. A ventilating system comprising:

a duct which communicates a room with an outside of the room;

a ventilator which ventilates the room forcibly to discharge the room air to an outside of the room, and supply outdoor air to the room through the duct connected to the ventilator;

a window controller provided to each window, wherein the window controller opens or closes the window to control to ventilate the room naturally;

a sensing device which senses pollutants in the room air, and conditions of the outdoor air and the room air; and

a controller which actuates at least one of the ventilator and the window controller to ventilate the room at least one of forcibly and naturally according to a result of sensing by the sensor.

2. The ventilating system as claimed in claim 1, wherein the sensing device comprises a VOC sensor for measuring a content of volatile organic compounds of the room air.

3. The ventilating system as claimed in claim 1, wherein the sensing device comprises:

a room temperature sensor for measuring a temperature of the room air; and

a room humidity sensor for measuring humidity of the room air,

4. The ventilating system as claimed in claim 1, wherein the sensing device comprises:

an outdoor temperature sensor for measuring a temperature of the outdoor air; and

an outdoor humidity sensor for measuring humidity of the outdoor air.

5. The ventilating system as claimed in claim 1, wherein the window controller makes the window to slide sideways to open/close the window.

6. The ventilating system as claimed in claim 1, wherein the window controller pushes/pulls the window forward/backward to open/close the window.

7. A method for controlling a ventilating system comprising the steps of:

measuring conditions of room air and outdoor air;

determining a ventilating method and a ventilating rate according to the measured conditions; and

ventilating the room by opening/closing at least one window automatically, and putting a ventilator into operation according to a result of determination.

8. The method as claimed in claim 7, wherein the step of determining a ventilating method and a ventilating rate further includes the step of determining a degree of pollution of the room air being within a preset range.

9. The method as claimed in claim 8, wherein the degree of pollution of the room air is dependent on a content of volatile organic compounds of the room air.

10. The method as claimed in claim 8, wherein the step of ventilating the room includes the step of closing the window if the degree of pollution of the room air is within a preset range.

11. The method as claimed in claim 8, wherein the step of ventilating the room includes the step of closing the window and stopping the ventilator if the degree of pollution of the room air is lower than a lowest reference value.

12. The method as claimed in claim 8, wherein the step of ventilating the room includes the step of closing the window and operating the ventilator at a low rate if the degree of pollution of the room air is higher than a lowest reference value and lower than a highest reference value.

13. The method as claimed in claim 8, wherein the step of determining a ventilating method and a ventilating rate further includes the step of determining the outdoor temperature of being within a preset range if the degree of pollution of the room air is higher than a preset range.

14. The method as claimed in claim 8, wherein the step of ventilating the room includes the step of closing the window and putting the ventilator into operation if the outdoor temperature is outside of a preset range.

15. The method as claimed in claim 13, wherein the step of determining a ventilating method and a ventilating rate further includes the step of determining the temperature difference between the room and the outside of the room being within the preset range if the outdoor temperature is within the preset range.

16. The method as claimed in claim 15, wherein the step of ventilating the room further includes the step of opening the window and stopping the ventilator if the temperature difference between the room and outside of the room is within a preset range.

17. The method as claimed in claim 15, wherein the step of determining a ventilating method and a ventilating rate further includes the step of determining outdoor relative humidity of being within a preset range if the temperature difference between the room and the outside of the room is within a preset range.

18. The method as claimed in claim 17, wherein the step of ventilating the room includes the step of opening the window to the maximum if the outdoor relative humidity is within a preset range.

19. The method as claimed in claim 15, wherein the step of ventilating the room further includes the step of opening the window to the minimum if the outdoor relative humidity is outside of the preset range.

20. The method as claimed in claim 15, wherein the step of ventilating the room further includes the step of closing the window and putting the ventilator into operation if the temperature difference between the room and the outside of the room is outside of the preset range.

21. The method as claimed in claim 15, wherein the step of determining a ventilating method and a ventilating rate further includes the step of determining room relative humidity of being within a preset range if the temperature difference between the room and the outside of the room is outside of the preset range.

22. The method as claimed in claim 21, wherein the step of ventilating the room further includes the step of closing the window and operating the ventilator at a maximum rate if the room relative humidity is within the preset range.

23. The method as claimed in claim 15, wherein the step of ventilating the room further includes the step of closing the window and operating the ventilator at a minimum rate if the room relative humidity is outside of the preset range.
