Description

Window mounted air conditioning system {WINDOW-MOUNTED AIR CONDITIONING SYSTEM}

The present invention relates to a window mounted air conditioning system.

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

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 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 part of the floor space, and dust is scattered in the process of sucking and discharging air at a position adjacent to the floor, thereby deteriorating air quality.

Recently, a technology for mounting a device to improve 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 Publication No. 10-2019-0132044, window type ventilation device (published date: 2019 27 November).

The window type ventilator includes a technology for improving indoor air quality by sucking in outdoor air and discharging indoor air in a state where one or both sides of a window are installed in a state upright with respect to the ground.

However, when the window type ventilation device is placed on both sides or one side of the window, the area of the window is greatly reduced, and if the area of the wall on which the window type ventilation device is formed is not sufficient, it is difficult to install the ventilation device. have

In this way, in order to improve indoor air quality while solving the problem that the area of the window is reduced due to the window type ventilation device being disposed on both sides or one side of the window, Publicated Utility Model No. 20-2010-0009897, a closed type window ventilation device October 08, 2010) has been disclosed.

Since the ventilator for the sealed window performs ventilation while being coupled to the upper or lower portion of the window frame, it is possible to perform ventilation while minimizing the decrease in area of the window.

However, the above-described Publication Patent No. 10-2019-0132044, window type ventilation device or utility model No. 20-2010-0009897, closed type window ventilation device commonly requires consumables such as filters to improve indoor air quality. , Since the ventilation device is firmly coupled to the window frame, the user cannot directly replace the consumables. There is discomfort.

In addition, the above-described Patent Publication No. 10-2019-0132044, a window type ventilation device or Utility Model No. 20-2010-0009897, a closed type window ventilation device are commonly coupled to the window frame of a window, and thus, the window frame of the window has a ventilation device. A large load is locally applied by the weight of the chair, and the window frame sags, causing a problem in that the window is not opened or closed.

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

Hereinafter, in one embodiment of the present invention, a path through which indoor air is discharged to the outdoors through the second through-hole 191, the exhaust fan 350, and the first through-hole 131 is distinguished from the first path D1. It will be defined as the second path D2.

More specifically, in the second path D2, indoor air introduced through the second through-hole 191 and the exhaust fan 350 is discharged to the outdoors through the sixth opening 136 formed in the rear plate 130. means path.

Meanwhile, referring to FIG. 7 , a first path D1 and a second path formed by an air supply fan 330 that supplies air from the outside to the inside and an exhaust fan 350 that supplies air from the inside to the outside ( D2) intersects each other on both sides of the passage partitioning member 310, so that indoor air and outdoor air can be mixed with each other at the intersection of the first and second paths D1 and D2.

In one embodiment of the present invention, power consumption is achieved through heat exchange due to a temperature difference between indoor air and outdoor air while preventing mutual mixing between indoor air and outdoor air at the intersection of the first and second paths D1 and D2. A total heat exchanger 370 is installed at the intersection where the first and second paths D1 and D2 intersect to reduce the heat exchanger 370 .

In one embodiment of the present invention, since the intersections where the first and second paths D1 and D2 intersect are formed on both sides of the flow path partition member 310, the total heat exchanger 370 is formed on both sides of the flow path partition member 310. are placed in each

Although in one embodiment of the present invention, it is shown and described that a pair of total heat exchangers 370 are disposed on both sides of the flow path partition member 310, otherwise, the intersection point where indoor air and outdoor air are crossed and mixed is the housing ( 100), if there are one or three or more total heat exchangers 370 may be one or three or more depending on the number of intersections in the storage space 120 of the housing 100.

The total heat exchanger 370 may be formed in, for example, a hexahedral block shape, and the total heat exchanger 370 is a first path connected to the first path (D1) so that air can flow through the first path (D1). The passage 371 and the second passage 372 connected to the second passage D2 so that air can flow to the second passage D2 crossing the first passage D1 are included.
