Description

Ventilation system {Ventilation system}

The present invention relates to a ventilation device, and more specifically, a total heat exchange passage and a bypass passage are configured separately, and universal installation in a wall-mounted type and a stand type is possible, and in the case of using a wall-mounted type, it is left and right. It relates to a ventilation device that is configured to enable all of the installation.

The content of fine dust and carbon dioxide contained in the air in the indoor space gradually increases over time due to the respiration of living organisms. In this case, fine dust may cause cerebrovascular disease, cardiovascular disease, and respiratory disease.

In general, air in an indoor space is discharged to the outdoors through a blower or natural ventilation by opening a window naturally, and outdoor air may be introduced into the interior. However, in this case, since total heat exchange between indoor air and outdoor air is not performed, unnecessary energy may be consumed for heating or cooling the indoor space. In addition, when a sudden temperature change occurs in the indoor space, people existing indoors may feel uncomfortable.

As a prior art, Korean Patent Registration No. 10-1233415 discloses a "window-attached hybrid ventilation device". According to this technology, it is possible to ventilate the air inside and outside the building by a forced ventilation method. However, this forced ventilation method may cause a noise problem, and energy may be wasted because total heat exchange is not performed.

On the other hand, the health of people living indoors may be affected by fine dust recently introduced from China and harmful chemicals due to sick house syndrome.

In addition, due to the recent reinforcement of the window insulation and airtightness performance, the airtightness of the window is reinforced significantly, so that air circulation is not performed, and atopy due to indoor pollution may occur.

Accordingly, it is possible to improve energy efficiency by performing total heat exchange beyond simple air cleaning, and in addition, the need for a ventilation device capable of mixing indoor air and outdoor air by selectively natural ventilation has emerged. As in Korean Patent No. 10-1555212, a "automatic ventilation device" that can be used by attaching to a window has been published.

Such an automatic ventilation device having a total heat exchange function improves energy efficiency through total heat exchange and can selectively perform natural ventilation, and has an excellent advantage of having an improved air cleaning function, but is formed to be attached to a window and used. Once installed, it is inconvenient to move, there is a limitation of the installation space, and there are disadvantages in that the total heat exchange efficiency cannot be maximized because it is adjacent to the outdoors.

Therefore, there is a need for a supplement that can maximize the excellence of the total heat exchange function while overcoming the above disadvantages.

In the present invention, in order to compensate for the above disadvantages, the total heat exchange passage and the bypass passage are separately configured, and universal installation in the wall-mounted type and the stand type is possible, and in the case of using the wall-mounted type, installation to the left and the right is possible.

For example, the LED may be provided with two LEDs, green and orange, and when the outdoor air is good, a green LED is irradiated, and when the outdoor air is bad, an orange LED can be irradiated to inform the user. In addition, in some cases, when the window handle and the ventilation device are interlocked to detect fine dust, radon, etc. above the reference value, the window handle may send a signal to the ventilation device to activate the ventilation system.

In addition, the ventilation device according to an embodiment of the present invention may include an air flow inducing device (not shown) for inducing the flow of air to the external connection pipe 100.

The airflow inducing device can control the temperature of the intake or exhaust by absorbing or releasing heat through the intake or exhaust passing through the external connection pipe 100, and through this, it can induce the flow of air by setting a temperature difference with the outdoor or indoor. I can.

For example, indoor air must be discharged to the outside, but when the outdoor air temperature is significantly higher than the indoor air temperature, the airflow induction device adjusts the temperature of the exhaust to the intermediate range of the temperature deviation between the indoor air temperature and the outdoor air. It can prevent the reduction of ventilation efficiency.
