First, the stand-type ventilation purifier 100 according to an embodiment of the present invention is capable of supplying and exhausting operation for exchanging indoor and outdoor air. Ventilation is performed as humans breathe, and for this purpose, the exhaust vent 132 is opened with an exhaust vent damper (not shown), and the vent 142 is closed with an vent damper 146. Next, the exhaust fan 134 is operated for about 3 minutes to discharge indoor air to the outdoors (exhaust operation). When the exhaust fan 134 stops operating after 3 minutes, the air supply fan 124 is operated for about 3 minutes to supply outdoor air to the room (air supply operation). If the air supply fan 124 stops operating 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. At this time, the operation time and total ventilation operation time of each of the exhaust fan 134 and the supply fan 124 can be set using the control panel 212 connected to the controller 210 or a remote control (not shown). there is.

During this supply/exhaust operation, when hot indoor air passes through the stand-type ventilation purifier (100), heat is stored in the heat storage type heat exchanger (190), and when cold air outside passes through the stand-type ventilation purifier (100), heat is stored. supply to increase energy efficiency. In addition, outdoor air passes through the second filter 160, the regenerative heat exchanger 190, the third filter 170, the fourth filter 180, and the photocatalytic ionization module 200 in the stand-type ventilation purifier 100. After sequentially passing through, harmful substances such as germs, molds, odor-inducing volatile organic compounds, cigarette smoke, and fine dust that may be contained in the air are removed, and then fresh air can be supplied to the room.

In addition, the stand-type ventilation purifier 100 according to a specific embodiment of the present invention is capable of air cleaning operation in which indoor air is purified and deodorized by passing through the stand-type ventilation purifier and then supplied back to the room. To this end, the exhaust vent 132 is closed with an exhaust vent damper (not shown), and the vent 142 is opened with an vent damper 146. The air supply fan 124 is continuously operated to purify and deodorize the air in the room, and then supply it back to the room through the ventilation hole 142. At this time, the operating time of the air supply fan 124 (that is, the operating time of the air cleaning operation) may be set using the control panel 212 connected to the controller 210 or the remote controller.

The supply/exhaust mode and the air cleaning mode described above may be performed automatically without user intervention. Specifically, a reference value (eg, 1,000 ppm) of CO ₂ content in indoor air for switching the driving mode may be set using the control panel 212 or the remote controller. If the CO ₂ content in the indoor air detected by the CO ₂ sensor (not shown) is less than this reference value, the controller 210 switches to the air cleaning mode, and the indoor air detected by the CO ₂ sensor When the CO ₂ content in the air reaches the reference value (1,000 ppm), the control device 210 switches to the supply/exhaust mode.

During this air cleaning operation, indoor air sequentially passes through the filters and the photocatalytic ionization module 200 in the stand-type ventilation purifier, and bacteria, mold, and volatile organic compounds that cause odors that may be contained in the air, After harmful substances such as cigarette smoke and fine dust are removed, fresh air can be supplied to the room again.

In addition, the stand-type ventilation purifier 100 according to a specific embodiment of the present invention is capable of fine dust removal operation and economizer cooling/heating operation.

For example, in the case of fine dust removal operation, when the amount of fine dust detected by the fine dust detection sensor (not shown) exceeds the reference value, the stand-type ventilation purifier 100 starts operating in the air cleaning mode. can be set to do so.

In the case of the economizer cooling/heating operation, when the temperatures of the indoor air and the outdoor air are measured using indoor and outdoor temperature sensors, the economizer cooling/heating operation is possible when the temperature difference is 5° C. or more, for example. For example, when the indoor temperature is 27° C. and the outdoor temperature is 22° C. or less during the transitional season (change of season), the economizer cooling operation starts and cool outdoor air is supplied to the room to provide cooling. Conversely, for example, when the indoor temperature is 18° C. and the outdoor temperature is 23° C. or higher, the economizer heating operation is started, and hot outdoor air is supplied to the room to perform heating.
