Description

Window frame ventilation device using counter-flow element}

The present invention relates to a window frame-type ventilation device using a counter-flow element, and more specifically, to ensure the degree of freedom in design, so that it can be manufactured so as not to block windows when manufacturing a ventilation device applied to a window frame, thereby improving the efficiency of the ventilation device. This relates to a window frame-type ventilation device using a counter-flow element that not only maximizes the installation space of the ventilation device, but also minimizes restrictions on the installation space of the ventilation device, thereby providing excellent space utilization.

Generally, in residential buildings or office buildings, windows are opened or closed or a separate ventilation system is operated to ventilate indoor polluted air. Such ventilation systems are rarely used in urban areas due to external noise and inflow of pollutants, and in most cases, a separate ventilation system is used to ventilate indoor air.

Accordingly, conventionally, various types of ventilation systems are installed around windows to improve ventilation efficiency, and among them, a ceiling-type heat exchange ventilation system is used.

The total heat exchange ventilation system has a built-in total heat exchanger with a total heat exchange element (not shown), an intake fan, and an exhaust fan, and exchanges total heat between indoor air and outdoor air when installed to connect to the intake duct and exhaust duct pre-built in the indoor ceiling. While doing it, I ventilate it.

However, since this conventional heat exchange ventilation system requires a duct to be built in advance in the ceiling for installation and a separate installation space to be formed in the ceiling, the ceiling structure must be changed in order to install it inside an existing house or building. At the same time, additional construction of ducts is necessary. As a result, there was a problem in that it was very difficult to construct in existing houses or buildings.

Accordingly, in Republic of Korea Patent No. 10-1144591, the cross-type heat exchange element maximizes the heat exchanger area to increase the heat exchange effect, and accommodates the heat exchanger module and its auxiliary devices in the inner space of the window frame to replace the existing heat exchanger. A window frame-type vertical heat exchange ventilation device has been published that can be installed without significantly deviating from the structure of the window frame, thereby saving energy as well as manufacturing and construction costs.

However, according to the above-mentioned prior art literature, the design of the ventilation device is inevitably limited as the width and height are manufactured to the same size, and when applied to a window frame type ventilation device, the efficiency is significantly reduced due to blocking the window. There is a problem with falling.

The background or prior art described herein is only intended to help understand the technical significance of the present invention, and does not mean technology that is widely known in the technical field to which this invention belongs before the application of the present invention.
