The measuring step (S101) is a step of measuring the components of the indoor and outdoor air, the temperature, and a biosignal included in a predetermined radius of the room.

For example, among the components of indoor and outdoor air, a fine dust concentration, a gas concentration, or a concentration of radon may be measured. In addition, indoor and outdoor temperatures may be measured, and biosignals included in a predetermined radius of the indoor may be measured.

The components of indoor and outdoor air to be measured are not limited to fine dust, gas, and radon, and may be changed according to the measurement location and measurement purpose. For example, components that can be included in the air, such as carbon monoxide, carbon dioxide, sulfuric acid, ozone and nitrogen, can be measured.

Here, the preset radius is a radius that can be set by any manipulation, and may be changed according to the size of the room. For example, in the case of a family house, the preset radius may be set to 10 m.

Comparing the values of each of the components of the indoor and outdoor air (S103) is a step of comparing the values of the components of the corresponding indoor and outdoor air, respectively, for example, indoor and outdoor fine dust concentration, gas concentration or radon Concentration and the like can be compared.

The step of disinfecting the inhaled outdoor air (S105) is a step of introducing outdoor air into the room when it is determined that the components of the outdoor air are better as a result of comparing the components of the indoor and outdoor air.

For example, among the components of the indoor and outdoor air, the gas concentration and the concentration of radon are similar, but when the concentration of fine dust is higher than the outdoor, it may be determined that the components of the outdoor air are better than the components of the indoor air. . In this case, outdoor air may be sucked in to enter the room.

That is, according to an embodiment of the present invention, a plurality of values of indoor and outdoor air components are respectively compared, and a comparison result of all the values that are not the results of any one value comparison is combined to determine which of the indoor air components and the outdoor air components. You can judge if the air component on the side is better.

Plasma is generated inside the piping for inhaling outdoor air, and the inhaled outdoor air can be sterilized by plasma.

The step of introducing the sterilized outdoor air into the room (S107) is a step of introducing the sterilized outdoor air into the room while discharging the indoor air to the outdoors, and circulating the indoor air and the outdoor air.

Estimating the number of people (S109) A step performed in parallel with comparing the components of indoor and outdoor air, by measuring a biosignal within a preset radius, and analyzing the measured biosignal within a predetermined radius This step is to estimate the number of people involved.

For example, a bio-signal about a person's breathing and pulse included in a preset radius is collected through a UWB (Ultra Wide Band) radar, and the collected bio-signals are filtered to estimate the number of people included in a preset radius. Can be.

That is, in the air cleaning method according to an embodiment of the present invention, a UWB radar may be used to measure a biosignal of a person included in a predetermined radius in a non-contact manner, and estimate the number of persons based on the measured biosignal. have.

Comparing the appropriate temperature and the room temperature (S111) is a step of calculating the appropriate temperature based on the estimated number of people, and comparing the calculated appropriate temperature with the measured room temperature.

The appropriate temperature is a suitable temperature preset according to the number of people included in the room, and may be preset by additionally considering the indoor area and use, carbon dioxide concentration, and humidity.

For example, the proper temperature in the summer of a typical home may be set to 26 to 28 degrees, and in the case of a museum, it may be set to 16 to 24 degrees.

The step of adjusting the room temperature (S113) is a step of adjusting the room temperature so that the room temperature is equal to an appropriate temperature.

For example, assuming that the measured indoor temperature is 20 degrees, the estimated number of people is 5, and the appropriate temperature when 5 people are gathered is 19.5 degrees, there is a difference between the measured indoor temperature and the calculated appropriate temperature. The room temperature can be increased until the room temperature is 24 degrees, which is the proper temperature.

As another example, in a museum where the proper temperature is set to 16 to 24 degrees, if a large number of people are located in a specific space and the carbon dioxide and room temperature are increased, the room temperature may be adjusted according to the predetermined appropriate temperature.

That is, the air cleaning method according to an embodiment of the present invention can automatically adjust the temperature by calculating the appropriate temperature based on the estimated number of people by measuring the bio-signal and adjusting the room temperature to the appropriate temperature. It has the advantage of reducing energy waste.
