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.

First claim

What is claimed is:

1 . A ventilation apparatus, comprising:
a casing having an inside partitioned into a first floor and a second floor; a first sharing duct provided in the first floor; a second sharing duct provided in the second floor; a first heat exchanger located in the first sharing duct, the first heat exchanger forming a permeable wall that partitions the first sharing duct into a first entering airflow chamber and a first exit airflow chamber; and a second heat exchanger located in the second sharing duct, the second heat exchanger forming a permeable wall that partitions the second sharing duct into a second entering airflow chamber and a second exit airflow chamber, wherein a main flow direction of air through the first heat exchanger is non-parallel to a main flow direction of air entering the first entering airflow chamber, and wherein a main flow direction of air through the second heat exchanger is non-parallel to a main flow direction of air entering the second entering airflow chamber.

2 . The ventilation apparatus of claim 1 , wherein the main flow direction of air through the first heat exchanger is perpendicular to the main flow direction of air entering the first entering airflow chamber, and
wherein the main flow direction of air through the second heat exchanger is perpendicular to the main flow direction of air entering the second entering airflow chamber.

3 . The ventilation apparatus of claim 1 , wherein the first entering airflow chamber is configured to receive a first one of an indoor air and an outdoor air, and
wherein the second entering airflow chamber is configured to receive a second one of an indoor air and an outdoor air.

4 . The ventilation apparatus of claim 1 , wherein the main flow direction of air through the first heat exchanger is horizontal, and
wherein the main flow direction of air through the second heat exchanger is horizontal.

5 . The ventilation apparatus of claim 1 , further comprising:
an indoor suction chamber connected to the first entering airflow chamber and the second entering airflow chamber, the indoor suction chamber configured to receive indoor air, an indoor discharge chamber connected to the first exit airflow chamber and the second exit airflow chamber, the indoor discharge chamber configured to discharge air indoors, an outdoor suction chamber connected to the first entering airflow chamber and the second entering airflow chamber, the outdoor suction chamber configured to receive outdoor air, and an outdoor discharge chamber connected to the first exit airflow chamber and the second exit airflow chamber, the outdoor discharge chamber configured to discharge air outdoors.

6 . The ventilation apparatus of claim 5 , wherein an indoor discharge fan is located in at least one of the indoor suction chamber and the indoor discharge chamber, and
wherein an outdoor discharge fan is located in at least one of the outdoor suction chamber and the outdoor discharge chamber.

7 . The ventilation apparatus of claim 6 , wherein the indoor discharge fan is located in the indoor discharge chamber, and
wherein the outdoor discharge fan is located in the outdoor discharge chamber.

8 . The ventilation apparatus of claim 5 , further comprising:
an indoor suction damper disposed in the indoor suction chamber and configured to selectively open or close any one of the first sharing duct and the second sharing duct; an indoor discharge damper disposed in the indoor discharge chamber and configured to selectively open or close any one of the first sharing duct and the second sharing duct; an outdoor suction damper disposed in the outdoor suction chamber and configured to selectively open or close any one of the first sharing duct and the second sharing duct; and an outdoor discharge damper disposed in the outdoor discharge chamber and configured to selectively open or close any one of the first sharing duct and the second sharing duct.

9 . The ventilation apparatus of claim 8 , wherein the indoor suction damper comprises:
a first indoor suction damper configured to open or close the first sharing duct; and a second indoor suction damper configured to open or close the second sharing duct.

10 . The ventilation apparatus of claim 8 , wherein the outdoor suction damper comprises:
a first outdoor suction damper configured to open or close the first sharing duct; and a second outdoor suction damper configured to open or close the second sharing duct.

11 . The ventilation apparatus of claim 8 , wherein the indoor discharge damper comprises:
a first indoor discharge damper configured to open or close the first sharing duct; and a second indoor discharge damper configured to open or close the second sharing duct.

12 . The ventilation apparatus of claim 8 , wherein the outdoor discharge damper comprises:
a first outdoor discharge damper configured to open or close the first sharing duct; and a second outdoor discharge damper configured to open or close the second sharing duct.

13 . The ventilation apparatus of claim 5 , wherein the first entering airflow chamber is located between the indoor suction chamber and the outdoor suction chamber, and
wherein the first exit airflow chamber is located between the indoor discharge chamber and the outdoor discharge chamber.

14 . The ventilation apparatus of claim 1 , wherein at least one of the first heat exchanger and the second heat exchanger comprises a first heat exchanger portion and a second heat exchanger portion, the first heat exchanger portion being angularly oriented with respect to the second heat exchanger portion.

15 . The ventilation apparatus of claim 14 , wherein the first heat exchanger portion and the second heat exchanger portion form a ‘V’ shape.

16 . The ventilation apparatus of claim 1 , wherein the first entering airflow chamber includes a first suction air guide therein configured to redirect a flow of air entering the first entering airflow chamber toward the first heat exchanger.

17 . The ventilation apparatus of claim 16 , wherein the first exit airflow chamber includes a first discharge air guide therein configured to redirect a flow of air exiting the first heat exchanger toward an exit of the first exit airflow chamber.

18 . A ventilation apparatus, comprising:
a casing having an inside partitioned into a first floor and a second floor; a first sharing duct provided in the first floor; a second sharing duct provided in the second floor; a first heat exchanger located in the first sharing duct that partitions the first sharing duct into a first entering airflow chamber and a first exit airflow chamber; a second heat exchanger located in the second sharing duct that partitions the second sharing duct into a second entering airflow chamber and a second exit airflow chamber; and a first suction air guide located in the first entering airflow chamber and configured to redirect a flow of air entering the first entering airflow chamber toward the first heat exchanger.

19 . The ventilation apparatus of claim 18 , further comprising:
a first discharge air guide located in the first exit airflow chamber and configured to redirect a flow of air exiting the first heat exchanger toward an exit of the first exit airflow chamber.

20 . The ventilation apparatus of claim 18 , wherein:
