It is characterized by one.

In recent years, fine dust and air pollutants have caused seriousness in many countries. In particular, schools have many students living in enclosed spaces such as classrooms. Is taking.

Accordingly, various air purifiers have been developed, and efforts have been made to improve the classroom environment by installing such air purifiers in each classroom.

Currently used air purifiers can be classified into a dry air purifier and a wet air purifier as a device that removes dust and dust or odors in the room and cleans the indoor air.

Dry type air purifiers are mainly composed of filter type using activated carbon, size of dust adsorbed by filter pore size, electric dust collection type using corona discharge or negative ion type, but frequent filter replacement It is cumbersome and there is a problem that ozone and nitrogen oxides can be generated by using corona discharge.

 Wet air cleaners purify the air by spraying water, which is often used in deodorization processes in chemical plants. Wet air cleaners are used in homes and offices due to noise and high power consumption. It is difficult to apply, and the dust or gas adsorbed on the water causes pollution of the water tank supplying the water to the cleaner, causing secondary problems.

In addition, conventional air cleaners have been developed and marketed for the purpose of purifying contaminated indoor air, but the concentration of carbon dioxide is continuously maintained by circulating and circulating the polluted air in the room repeatedly while blocking the inflow of fresh external air. When the window is opened to solve the increase (continuous decrease in oxygen concentration), there is a problem in that outside air having a high concentration of fine dust is introduced into the room, and thus, air purification (removal of fine dust) cannot be properly achieved.

In order to solve this problem, it is necessary to install a total heat exchange facility for each building separately from the air cleaner for indoor installation, but there is a problem in that a large cost is required for the construction of the total heat exchange facility in a non-new building.

Therefore, there is an urgent need to introduce a new concept of indoor air cleaner that enables indoor air cleaning and ventilation at low cost and simple structure.

The tubular body is connected to the outside air inlet 104, and the outside air can be easily introduced by only a simple construction of exposing the end of the tubular body to the outside.

As shown in FIGS. 1 and 3, the second indoor air inlet 102 serves as an inlet for introducing indoor air into the space between the intermediate partition 140, the lower partition 150, and the vertical partition 160. 2 The indoor air introduced through the indoor air intake port 102 passes through the heat exchange unit 240 in the horizontal direction, and is introduced into the external air intake port 104 by the operation of the air supply air blower 210 to the first outside. Through the air dropping hole 141, the heat exchanger 240 crosses the external air descending in the vertical direction (not directly contacted and mixed, but only heat exchange in the process of passing through the heat exchange element) to perform heat exchange. do.

Although not separately illustrated in the accompanying drawings, the second indoor air intake port 102 may be equipped with a separate filter to prevent contamination of the total heat exchange part 240 or the exhaust blower 230. In addition, the second indoor air inlet 102 is not necessarily provided at the position shown in the drawing, and constitutes an appropriate internal flow path and passes through the heat exchange part 240 to exchange heat with the external air at another location. It may be provided.

The indoor air outlet 105 flows into the second indoor air intake port 102 and passes through the heat exchange unit 240, and then flows into the space between the intermediate partition wall 140, the lower partition wall 150, and the vertical partition wall 160. Serves as an outlet to discharge the indoor air to the outside (outdoor).

The exhaust blower 230 is installed in a space between the intermediate partition 140, the lower partition 150, and the vertical partition 160, and introduces indoor air into the second indoor air inlet 102 to exhaust the indoor air. ) Serves as a power unit to discharge to the outside (outdoor).

The heat exchange part 240 is installed in a space between the intermediate partition 140, the lower partition 150, and the vertical partition 160, and descends through the first external air downhole 141 and the second interior. Heat-exchanging is performed between the indoor air introduced into the air inlet 102 and discharged to the outside through the indoor air outlet 105.

The total heat exchange part 240 is made of the same or similar structure as a general total heat exchange element in which heat exchange is performed between outdoor air and indoor air that cross each other. That is, the heat exchange is performed only through the insulating membrane while passing through a plurality of isolated cross flow paths, not a structure in which outdoor air and indoor air are directly contacted and mixed.

The blocking damper 170 opens and closes the outside air inlet 104 and serves to inflow or block outside air as necessary.

The blocking damper 170 may be opened and closed by an electric motor, and may be a general structure that is automatically controlled.

The controller 300 controls the operations of the air supply air blower 210, the exhaust air blower 230, and the blocking damper 170.

The control unit 300 may be provided with a sensor function for detecting the carbon dioxide concentration, the volatile organic compound concentration, the fine dust concentration contained in the indoor air, the air supply air blowing unit 210, exhaust according to the signal detected through the sensor function Each of the blower 230 and the blocking damper 170 is individually controlled.

In addition, the controller 300 may be a sensor function for detecting the temperature and humidity of the room.

Looking at the specific content of the control unit 300 to individually control the air supply blower 210, the exhaust blower 230 and the blocking damper 170 as follows.

(1) When the carbon dioxide concentration, the volatile organic compound concentration, and the fine dust concentration included in the indoor air are less than the preset reference value, the controller 300 controls the air supply air blower 210 and the exhaust air blower in the state where the blocking damper 170 is closed. The operation of 230 is stopped to prevent unnecessary power consumption.

(2) When the carbon dioxide concentration and the volatile organic compound concentration included in the indoor air are less than the predetermined reference value and only the fine dust concentration is higher than the reference value, the control unit 300 is in the closed state (if it is open, the blocking damper 170). In the process of closing the above), only the air supply blower 210 is operated and the operation of the exhaust blower 230 is stopped.

In other words, while only the indoor air is repeatedly circulated in a state where ventilation with external air is not achieved, fine dust is removed.

(3) When the concentration of carbon dioxide or volatile organic compounds contained in the indoor air is equal to or greater than a predetermined reference value, the controller 300 controls the air supply air blowing unit 210 and the exhaust air blowing unit 230 while the blocking damper 170 is opened. All work.

In other words, the indoor air is discharged and the external air is introduced at the same time, and heat exchange through the heat exchanger 240 is minimized in the process to minimize the energy loss, and the indoor air circulated with the newly introduced external air is mixed. By removing the fine dust contained in the supply to the room, by removing the fine dust, carbon dioxide and volatile organic compounds outdoor discharge, and oxygen can be made at the same time.

(4) The indoor dust temperature is within the range between the preset lower limit value and the upper limit value (the temperature of the external air is also in a similar range so that no heat exchange is necessary), and the concentration of fine dust contained in the indoor air is set in advance. If less than, the concentration of carbon dioxide contained in the indoor air or the concentration of the volatile organic compound is more than a predetermined reference value control unit 300 stops the operation of the air supply air blowing unit 210 in the state that the blocking damper 170 is closed, the exhaust blower Only operate 230.

In other words, instead of circulating and purifying indoor air or actively supplying fresh outside air to the room, the indoor air is simply discharged to the outside by activating the exhaust blower 230 to quickly exhaust the concentration of carbon dioxide or volatile organic compounds in the room. Can be reduced.

As described above, specific embodiments of the present invention have been described with reference to the accompanying drawings, but the scope of protection of the present invention is not necessarily limited to these embodiments, and various design changes and known technologies are not limited to the scope of the present invention. In the case of the addition or deletion, simple numerical limitation, etc., the scope of the present invention is clearly clarified.
