Benefits of technology

The present invention provides a ventilation apparatus with the following technical effects: increasing the contact area with air, minimizing the movement resistance of air, reducing power consumption by minimizing the height difference of the air movement, improving heat exchange efficiency, and maintaining a constant velocity of discharged air. Additionally, the apparatus is designed to ensure uniform subject heat exchange with the entire area of the heat exchanger.

Problems solved by technology

If air-conditioning is performed using only the indoor air, however, the quality of the indoor air is gradually reduced.

first embodiment

[0060]An operation of the ventilation apparatus in accordance with the present invention is described in detail below with reference to related drawings.

[0061]Ventilation Mode

[0062]In ventilation mode, some of an indoor air is discharged to the outside, and fresh air is sucked from the outside and supplied to the inside.

[0063]In this case, in the ventilation apparatus according to the present embodiment, while the ducts in the first floor and the second floor are alternately open and closed, an outdoor air is supplied to the inside, and an indoor air is discharged to the outside.

[0064]For example, a case where an outdoor air is supplied to the inside through the first floor and an indoor air is discharged to the outside through the second floor is described below (refer to FIG. 4).

[0065]First, in order to supply the outdoor air to the inside, the first outdoor suction damper 66-1 and the first indoor discharge damper 64-1 disposed in the first floor are open, and the remaining dampe...

second embodiment

[0095]FIG. 8 is an exemplary diagram illustrating that the duct structure of a ventilation apparatus in accordance with the present invention is divided into the first floor and the second floor in order to describe the duct structure.

[0096]The ventilation apparatus according to the present embodiment includes a plurality of heat exchangers disposed in a single layer, unlike in the first embodiment.

[0097]More specifically, the ventilation apparatus according to the present embodiment may include two first heat exchangers 41-1 and 41-2. One (e.g., 41-1) of the two first heat exchangers is installed close to the first indoor discharge damper 64-1, and the other (e.g., 41-2) of the two first heat exchangers is installed close to the first outdoor discharge damper 68-1.

[0098]Furthermore, one (e.g., 42-1) of two second heat exchangers is installed close to the second indoor discharge damper 64-2, and the other (e.g., 42-2) of the two second heat exchangers is installed close to the secon...

third embodiment

[0103]FIG. 9 is an exemplary diagram illustrating that the duct structure of a ventilation apparatus in accordance with the present invention is divided into the first floor and the second floor in order to describe the duct structure.

[0104]The ventilation apparatus according to the present embodiment may further include a guide configured to guide the flow of air and installed in at least one of the first sharing duct 11 and the second sharing duct 12.

[0105]In the present embodiment, the guide may include a first suction guide 71-1 and a first discharge guide 71-2 installed in the first sharing duct 11 and a second suction guide 72-1 and a second discharge guide 72-2 installed in the second sharing duct 12.

[0106]In this case, the first suction guide 71-1 is configured to guide sucked air to the first heat exchanger 41, and the second suction guide 72-1 is configured to guide sucked air to the second heat exchanger 42.

[0107]Furthermore, the first discharge guide 71-2 is configured t...

Abstract

A ventilation apparatus includes a casing having the inside partitioned into a first floor and a second floor. A first sharing duct is formed in the first floor and configured to suck one of indoor air and outdoor air and to have the sucked air horizontally moved. A second sharing duct is formed in the second floor and configured to suck the other of indoor air and outdoor air and to have the sucked air horizontally moved. First and second heat exchangers are disposed in the first and second sharing ducts, respectively. The ventilation apparatus is advantageous in that air resistance is minimized, horizontally moving air is subject to heat exchange with the entire area of the heat exchanger, and efficiency of heat exchange between air and the heat exchanger is improved because air is divided into the first floor and the second floor and horizontally moved.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit under 35 U.S.C. §119(a) to Patent Application No. 10-2015-0004411, filed in the Republic of Korea on Jan. 12, 2015, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a ventilation apparatus.[0004]2. Discussion of the Related Art[0005]In general, a ventilation apparatus refers to an apparatus configured to discharge contaminated indoor air, suck in fresh and clean outdoor air, and supply the fresh and clean outdoor air to the indoors.[0006]An air-conditioner not having a ventilation function cools or heats indoor air while circulating the indoor air.[0007]In this case, the air-conditioner to which outdoor air is not introduced filters the indoor air through a filter, etc. If air-conditioning is performed using only the indoor air, however, the quality of the indoor air is gradually reduced.[000...
