VENTILATION DEVICE FOR WINDOWS

The present invention relates to a ventialtion device, and particularly to a ventilation device for windows, which is disposed in a window frame so as to discharge indoor air to an outdoor space and introduce outdoor air into an indoor spacem, and also which can perform heat exchange between the air discharged to the outdoor space and the air introduced into the indoor space.

Generally, a carbon dioxide content in indoor air is gradually increased due to breathing of living things, as time passes. And since the increased carbon dioxide content inhibits the breathing of living things, it is necessary to frequently replace the indoor air with fresh air. To this end, In residential buildings, officetel buildings and the like, ventilation is achieved by opening and closing windows, or by providing a separate ventilation system for ventilating the polluted indoor air. The ventilation system can be classified into a ceiling type and a window type.

However, in case of the ventilation achieved by opening and closing windows, there is a problem that outer noise and pollutants may be introduced together with outdoor air. In case of the ceiling type ventilation system, since the ventilation is typically installed to be connected with an introduction duct and a discharge duct which are previously constructed in the ceiling, there is a problem that it is required to additionally construct the ducts for installing the ventilation system in the ceiling. In case of the window type ventilation system, there is a problem that it is required to separately form an installation space for the ventilation system in windows of the existing buildings.

Furthermore, if heat exchange is not performed between the indoor air and the outdoor air, while the indoor air is forcibly discharged to the outdoor space and the outdoor air is introduced into the indoor space, there are some problems in that unnecessary expense for air conditioning and heating of the indoor space is required and also persons in the building may have an unpleasant feeling due to a rapid change in temperature.

An object of the present invention is to provide a ventilation device for windows, which can perform heat exchange between air discharged to an outdoor space and air introduced into an indoor space and also can solve the problems in the conventional ventilation system, and particularly which does not reuqire a separate installation space

To achieve the object of the present invention, the present invention provides a ventilation device for windows, including a heat exchange module which is buried in a transom out of a frame of a divided window; an intake module which is buried in a mullion located at a side surface of the transom; and an exhaust module which is buried in the mullion so as to be located at an upper side of the intake module, wherein the heat exchange module supplies outdoor air introduced from an outdoor space to the exhaust module and also receives the indoor air introduced by the intake module and then discharges the indoor air to an outdoor space, and heat exchange is achieved between the outdoor air and the indoor air without mixture therebetween.

Further, the present invention provides a ventilation device for windows, including a heat exchange module which is buried in a transom out of a frame of a divided window; an intake module which is buried in a mullion located at a side surface of the transom; and an exhaust module which is buried in the mullion so as to be located at a lower side of the intake module, wherein the heat exchange module supplies outdoor air introduced from an outdoor space to the exhaust module and also receives the indoor air introduced by the intake module and then discharges the indoor air to an outdoor space, and heat exchange is achieved between the outdoor air and the indoor air without mixture therebetween.

Preferably, the heat exchange module includes a heat exchange device for performing the heat exchange between the indoor air and the outdoor air, and the outdoor air is purified by the outdoor air filter after being introduced into the heat exchange module and before being introduced into the heat exchange device, and the indoor air is purified by the indoor air filter after being introduced into the heat exchange module and before being introduced into the heat exchange device.

Preferably, the exhaust module is provided with a plurality of outdoor air discharge ports which are arraged in a length direction of the exhaust module in order to discharge the outdoor air, and the mullion is formed with an opening which is communicated with the outdoor air discharge port of the exhaust module, so that the outdoor air discharged from the outdoor air discharge port is supplied to an indoor space.
