Window type ventilation system with a room purifying filter and heat exchanger}

The present invention relates to a window-type ventilator with a built-in filter having an indoor air cleaning function. More particularly, the present invention relates to a window-type ventilator having a filter installed therein. In the ventilator, a filter with a built-in air clean function can be used to change the structure of the heat exchanger so that part of the indoor air passing through the heat exchanger is discharged to the outside, and the other part is purified and introduced back into the room to reduce energy loss. A window ventilator.

In addition to the ability to view the indoors and outdoors in the room, and to provide natural light in the room, the windows installed in the building are used to ventilate the air inside the contaminated room. When installed, and to ventilate the indoor air to open the window, in this case through the open window can be ventilated indoor air in a short time.

However, noise, soot, smog, dust, yellow dust, pollen, etc., from outside are introduced into the room without filtration through open windows during ventilation, which contaminates the indoor air. There is a problem that the cold outdoor air flows into the room to lower the room temperature, thereby causing additional energy loss by operating the heating device to increase the room temperature.

Recently, awareness of the importance of indoor environment and indoor air is increasing due to the increase of activity time indoors.In the case of public housing, the airtightness of the window decreases as the airtightness of the window decreases but the ventilation rate decreases. Deterioration is inevitable. Air purifiers have been developed and marketed for the purpose of purifying contaminated indoor air. However, these air purifiers purify indoor contaminated air and simply circulate it indoors while blocking the continuous inflow of fresh external air. Therefore, there is a problem that the effectiveness is inferior.

One of the technologies which appeared to solve such a problem is Patent Registration No. 476156, "Window with ventilation device". Briefly describing the technical contents with reference to FIGS. 1A and 1B, the case is detached and attached to the window frame. The air outlet (3) and the outside air inlet (4) are formed on the outdoor side of (1), and the inside air inlet (2) and the outside air supply port (5) are formed on the inside side of the case, and the outside air formed inside the case. Heat exchanger 6 is installed inside the case for mutual heat exchange between outside air and inside air passing through the inflow path and inside air discharge path, and a fan 8 for sucking inside air and outside air is installed, and the outside air is sucked into the outside air inlet. The filter 7 is installed to purify the air before the outdoor air passing through the inflow path is introduced into the room.
