Window type air circulation system

The present invention relates to a window-type air circulation device installed in a window to ventilate indoor and outdoor air.

In general, air purifiers are intended to purify indoor air, and since air purifiers purify only indoor air by circulating it, there is a problem in that ventilation is reduced.

To solve this problem, air purifiers have been developed that can purify outdoor air and supply it indoors. However, when the temperature difference between indoor and outdoor air is large, indoor cooling and heating efficiency decreases, so the temperature of indoor and outdoor air is exchanged. A ventilation device equipped with a heat exchange element has been disclosed as a window-type ventilation device equipped with a rotary heat exchange module in Korea Patent Publication No. 10-2014-0034502 (published on March 20, 2014).

The above-mentioned conventional window-type ventilation device is installed in a window and exchanges heat between the outside air and the inside air through a heat exchange module when introducing outside air, making it easy to install and preventing a decrease in indoor cooling and heating efficiency.

However, the conventional window-type ventilation device had the problem of causing discomfort to the occupants as the supplied air was discharged directly toward the occupants, and not only caused water leaks and breakdowns due to rainwater flowing in through the exterior appliances, but also caused the exterior appliances to be blocked when not in use. There was a problem with contamination occurring due to foreign substances or insects entering the system.

In addition, there was a problem in that manufacturing costs increased because a remote control for separate operation had to be manufactured separately from the operation unit and the remote control.

The present invention was devised to solve the above-mentioned problems, and the problem to be solved by the present invention is to disperse the supplied air by the distribution panel to prevent the air from being discharged directly toward the occupants, thereby causing discomfort to the occupants. Not only can this be prevented, but by installing an outside air damper on the outside device, you can prevent the inflow of foreign substances when not in use, and by installing an outside air cap on the outside device, you can prevent the inflow of rainwater, thereby preventing water leaks or malfunctions. The purpose is to provide a window-type air circulation device.

In addition, a remote control groove that accommodates the operating remote control is formed in the distribution panel to prevent loss of the remote control, and at the same time, it can be operated by a remote control coupled to the remote control groove without constructing a separate operation part, thereby reducing production costs. The purpose is to provide an air circulation device.
