How it works

Hereinafter, a method of operating the ventilator 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

First, the ventilation cleaner 100 according to the embodiment of the present invention is capable of ventilation operation to exchange the air outside the room. To this end, the exhaust port 132 is opened by the exhaust port damper 136, and the ventilation port 142 is closed by the ventilation port damper 146. Subsequently, the exhaust fan 134 is operated for about 3 minutes to exhaust the indoor air to the outside. When the exhaust fan 134 stops operation after 3 minutes, the air supply fan 124 is operated for about 3 minutes to supply outdoor air to the room. When the air supply fan 124 stops operation after 3 minutes, the operation of the exhaust fan 134 and the air supply fan 124 (about 3 minutes each) is repeated in this manner. In this case, the operation time and the total ventilation operation time of the exhaust fan 134 and the air supply fan 124 may be set using the remote controller 198 connected to the control device 190.

During the ventilation operation, when the indoor hot air passes through the ventilation purifier 100, the heat is stored in the heat storage heat exchanger 150, and when the outdoor cold air passes through the ventilation purifier 100, the heat is supplied to provide energy efficiency. Can increase. In addition, outdoor air sequentially passes through the deodorizing filter 180, the fine dust collecting filter 170, the heat storage heat exchanger 150, the antibacterial deodorizing cartridge 160 and the deodorizing filter 180 in the ventilation purifier 100. While the harmful substances such as bacteria, mold, odor-causing volatile organic compounds, tobacco smoke, and fine dust may be contained in the air, fresh air may be supplied to the room.

In addition, the ventilation cleaner 100 according to the embodiment of the present invention is capable of clean operation of supplying the indoor air back to the room after purifying and deodorizing through the ventilation cleaner. To this end, the exhaust port 132 is closed by the exhaust port damper 136, and the ventilation port 142 is opened by the ventilation port damper 146. The air supply fan 124 is continuously operated to purify and deodorize the air in the room, and then supply the air back to the room through the ventilation hole 142. At this time, the operating time (that is, the operating time of the clean operation) of the air supply fan 124 may be set to the remote controller 198 connected to the control device 190.

Such clean driving may be performed automatically without the driver's intervention. Specifically, using the remote controller 198, the CO ₂ content (minimum value; for example, 800 ppm) in the indoor air where the clean operation is started and the CO ₂ content (maximum value; for example, the indoor air where the clean operation is stopped) 1,000 ppm) can be set. If the CO ₂ content in the indoor air detected by the CO ₂ sensor 192 reaches this minimum value, the clean operation is started by the controller 190 and the indoor air detected by the CO ₂ sensor 192. When the CO ₂ content in this reaches this maximum value, the clean operation is stopped by the control apparatus 190, and it can switch to the ventilation operation which introduces outdoor air automatically.

In this clean operation, the indoor air sequentially passes through a deodorizing filter, an antibacterial deodorizing cartridge, a heat storage heat exchanger, a fine dust collection filter, and a deodorizing filter in a ventilation purifier. After the volatile organic compounds such as volatile organic compounds, tobacco smoke, and fine dust are removed, fresh air may be supplied to the room again.

In addition, the ventilation cleaner 100 according to the embodiment of the present invention is also capable of heating and cooling operation using outdoor air. For example, when indoor and outdoor air temperature is measured using indoor and outdoor temperature sensors, economizer cooling and heating operation is possible when the temperature difference is 5 ° C or more. For example, when the indoor temperature is 27 ° C. and the outdoor temperature is 22 ° C. or lower in the season, the economizer cooling operation is started to supply cool outdoor air to the room for cooling. On the contrary, for example, when the indoor temperature is 18 ° C. and the outdoor temperature is 23 ° C. or more, the economizer heating operation may be started to supply hot outdoor air to the room for heating.
