Description

Air ventilation purifier

The present invention relates to an air ventilation purifier that performs ventilation and cleaning functions of indoor air, and performs heat exchange of air introduced and discharged during ventilation, and purifies the air introduced from the outside, and then discharges the indoor air. It relates to an air ventilation purifier capable of increasing the ventilation efficiency by adjusting the direction.

Since the interior of a general home or office is closed for a lot of time, the amount of carbon dioxide increases when the time to be sealed increases, and the degree of pollution of the indoor air deteriorates. In general homes or small offices that do not have special ventilation means, you can ventilate the room by opening a window or door, but there is a hassle that a person has to do. When the size of the room is large, it is not only inconvenient to open a window or door at a certain time to ventilate it, but it may be impossible depending on the installation location of the window or door.

If external air with high temperature and humidity is forcibly introduced into the room in summer, indoor air with low temperature and humidity may be leaked to the outside by the air conditioner. Conversely, external air with low temperature in winter may be forced into the room. If it is introduced into the room, there may be a problem in that indoor air having a high temperature is leaked to the outside by the heating device.

In order to prevent this problem, a ventilation device using a total heat exchanger for exchanging heat between indoor air discharged to the outside and external air supplied to the inside is proposed and used. The total heat exchanger has a structure in which a flow path through which indoor air flows and a flow channel through which outdoor air flows are alternately formed so that heat exchange between indoor air and outdoor air is possible (refer to Korean Patent Registration No. 10-1790696).
