Method for enlarging ventilation by using air supply and exhaust mixing of equipment for window and kitchen hood}

The present invention relates to a method for maximizing ventilation, and in particular, by ventilating through the large-capacity hood in the kitchen together with the air supply mode operation of the ventilation system for windows and doors in a residential household, such as an apartment, ventilation through the creation of a one-way airflow in the residential household The present invention relates to a method of maximizing ventilation by using a combination of ventilation and exhaust ventilation for a window and a kitchen hood to maximize efficiency.

Recently, the awareness of the importance of indoor environment and air quality is increasing due to the increase of indoor activity time and the tendency of building density. In the case of residential buildings with high-rise buildings such as apartments and office buildings, it is extremely difficult to open windows due to the fear that polluted air from outside may enter the room. As a result, the quality of the indoor air can not be deteriorated unless a separate ventilation means is provided.

Conventionally, air purifiers have been developed and marketed for the purpose of purifying air containing various pollutants such as exhaust gas and fine dust discharged from mechanical devices such as automobiles. While blocking the continuous inflow of fresh outside air, the polluted air introduced through windows and the like is purified and simply circulated repeatedly in the room.

A window type ventilation device for solving such a problem is disclosed in Korean Laid-Open Patent Publication No. 10-2007-89001 (hereinafter referred to as Prior Art 1). Window type ventilation device disclosed in the prior document 1 is embedded in the longitudinal member (mullion, mullion) of the window frame, and includes a cross flow fan and a heat exchanger. The crossflow fan introduces air from the outdoor space into the indoor space through the upper part of the mullion, and discharges air from the indoor space into the outdoor space through the lower part of the mullion. The heat exchanger accommodates a heat exchange medium such as ethylene glycol and glycerin glycol therein and extends along the extension direction of the mullion. Heat exchange between the incoming air and the discharged air is achieved by the up and down reciprocating flow of the heat exchange medium.

In addition, Korean Patent Laid-Open Publication No. 10-2004-75686 (hereinafter referred to as Prior Art 2) also discloses a window provided with a ventilation device to solve the above-mentioned problem. The window provided with the ventilator disclosed in the prior document 2 includes a case embedded in a transverse member (transom) of the window frame. Inside the case, a first fan for discharging the air of the indoor space to the outdoor space, a second fan for introducing the air of the outdoor space to the indoor space, a mixture between the air introduced from the outdoor space and the air discharged to the outdoor space In order to prevent barriers, a heat exchanger is provided for heat exchange between the air introduced into the outdoor space and the air discharged into the outdoor space. As the heat exchanger, a fin type or a type in which a plurality of plate bodies are stacked is used.
