Description

MULTI-MODE WINDOW-MOUNTED AIR CONDITIONING SYSTEM

The present invention relates to a multi-mode window air conditioning system.

Recently, as the importance of the indoor environment has been highlighted, various technologies have been developed to improve ventilation and indoor air quality.

In general, in order to improve or purify indoor air, a floor-type air purifier that sucks indoor air and purifies it with a filter is widely used.

In the case of floor-type air purifiers, it is difficult to improve the indoor carbon dioxide concentration because most of them are placed on the floor and filter indoor air without introducing outside air.

In addition, since the floor type air purifier is disposed on the floor, it occupies a part of the floor space, and dust is scattered in the process of suction and discharge of air at a position adjacent to the floor, which may deteriorate the air quality.

Recently, a technology for installing a device for improving air quality on a window frame has been developed, and as a technology for a device installed on a window frame to improve air quality, Korean Patent Laid-Open No. 10-2019-0132044, a window-type ventilation device (published date: 2019) 27 November).

The window type ventilator includes a technology for improving indoor air quality by inhaling outdoor air and discharging indoor air in a state of being erected with respect to the ground on one side or both sides of a window.

However, when the window type ventilation device is disposed on both or one side of the window as described above, the area of the window is greatly reduced, and when the area of the wall where the window type ventilation device is formed is not sufficient, it is difficult to install the ventilation device. have

As such, in order to improve indoor air quality while solving the problem of reducing the area of a window by placing window-type ventilation devices on both or one side of the window as described above, published Utility Model Publication No. 20-2010-0009897, Ventilation device for sealed windows October 08, 2010) has been disclosed.

Since the ventilation device for the sealed window performs ventilation in a state coupled to the upper or lower portion of the window frame of the window, ventilation can be performed while minimizing the reduction in the area of the window.

However, the aforementioned Patent Publication No. 10-2019-0132044, the window type ventilation device or utility model No. 20-2010-0009897, and the ventilation device for a closed window commonly require consumables such as a filter to improve indoor air quality. , because the ventilation device is firmly coupled to the window frame, the user cannot directly replace the consumables. There is discomfort.

In addition, the aforementioned Patent Publication No. 10-2019-0132044, a window type ventilation device or utility model No. 20-2010-0009897, a ventilation device for a closed window are commonly coupled to the window frame of the window, and thereby the ventilation device is provided on the window frame of the window. Due to the weight of the chair, a large load is applied locally, causing the window frame to sag, which may cause a problem that the window cannot be opened or closed.

In addition, the aforementioned Patent Publication No. 10-2019-0132044, window type ventilation device or utility model No. 20-2010-0009897, and closed window ventilation device commonly require at least three motors for supply air, exhaust and air purification. In this way, when supplying air, exhaust and air cleaning are performed using a plurality of motors, the size of the ventilation device becomes unnecessarily large, the weight of the ventilation device becomes heavy, and the production cost of the ventilation device increases.

Republic of Korea Patent Publication No. 10-2019-0132044, window type ventilation device (published on: November 27, 2019) Republic of Korea Public Utility Model No. 20-2010-0009897, Ventilation device for sealed windows (published on October 08, 2010)
