Abstract

A ventilation apparatus including a housing having an inlet flow path to discharge outdoor air, to an indoor space through a first outlet, and an outlet flow path to discharge indoor air, to an outdoor space through a second outlet, a total enthalpy heat exchanger in which air flowing along the inlet flow path and air flowing along the outlet flow path exchange heat, and a heat exchanger to remove moisture in the air flowing along the inlet flow path. The housing including a connection flow path connecting the inlet flow path to the outlet flow path, and a connection path opening and closing unit configured to selectively open and close the connection flow path. The connection flow path to allow indoor air, to pass through the heat exchanger and flow to the first outlet while preventing the indoor air from flowing to the total enthalpy heat exchanger.

First claim

What is claimed is:

1. A ventilation apparatus comprising:
a housing including:
an inlet flow path along which a flow of outdoor air, introduced through a first inlet, is flowable to an indoor space through a first outlet,
an outlet flow path along which a flow of indoor air, introduced through a second inlet, is flowable to an outdoor space through a second outlet,
a connection flow path along which the flow of indoor air is flowable to the inlet flow path,
a connection path valve configured to selectively open and close to respectively open and close the connection flow path
a first housing including a first hole through a surface of the first housing, the first hole being asymmetrical with respect to a center line of the housing extending in a long axis direction of the housing or a center line of the housing extending in a short axis direction of the housing, the first hole including:
a first region adjacent to a first side of the housing rather than to a second side of the housing with respect to a center line of the housing extending along a direction in which the first side and the second side of the housing extend, and
a second region, and

a second housing coupled to the first housing in an up and down direction and including a second hole through a surface of the second housing, the second hole having a shape corresponding to a shape of the first hole in the up and down direction;

a total enthalpy heat exchanger in the inlet flow path and the outlet flow path and configured exchange heat between the flow of outdoor air and the flow of indoor air, the total enthalpy heat exchanger adjacent to the first side of the housing rather than to the second side of the housing with respect to the center line of the housing extending along a direction in which the first side and the second side of the housing extend;
a heat exchanger in the inlet flow path and configured to remove moisture in air flowing along the inlet flow path; and
a drain tray configured to collect condensed water generated by the heat exchanger,
wherein the connection flow path is configured to allow the flow of indoor air to pass through the heat exchanger and flow to the first outlet while preventing the flow of indoor air from flowing to the total enthalpy heat exchanger,
the first region is configured to allow the total enthalpy heat exchanger to be drawn out to an outside of the housing, and
the second region is configured to allow the drain tray to be drawn out to the outside of the housing.

2. The ventilation apparatus of claim 1 , wherein
the housing is formed of an insulating material.

3. The ventilation apparatus of claim 1 , wherein
relative to the first inlet, the first outlet, the second inlet, and the second outlet, the total enthalpy heat exchanger is closest to the first inlet.

4. The ventilation apparatus of claim 1 , further comprising:
a filter configured to collect foreign substances in the outdoor air introduced through the first inlet, and arranged to face an intake end of the total enthalpy heat exchanger.

5. The ventilation apparatus of claim 4 , wherein
the connection flow path is configured to allow the flow of indoor air to pass through the heat exchanger and flow to the first outlet while preventing the indoor air from flowing to the total enthalpy heat exchanger and the filter.

6. The ventilation apparatus of claim 1 , wherein
the housing includes:
a first inlet chamber between the first inlet and the total enthalpy heat exchanger and forming a portion of the inlet flow path;
a second inlet chamber between the first outlet and the total enthalpy heat exchanger and forming another portion of the inlet flow path;
a first outlet chamber between the second inlet and the total enthalpy heat exchanger and forming a portion of the outlet flow path and
a second outlet chamber between the second outlet and the total enthalpy heat exchanger and forming another portion of the outlet flow path, and

the heat exchanger is in the second inlet chamber.

7. The ventilation apparatus of claim 6 , wherein
the connection flow path connects the first outlet chamber to the second inlet chamber.

8. The ventilation apparatus of claim 7 , further comprising:
a first blower in the inlet flow path and drivable to flow the flow of outdoor air; and
a second blower in the outlet flow path and drivable to flow the flow of indoor air,
wherein the first blower is in the second inlet chamber and the second blower is in the second outlet chamber.

9. The ventilation apparatus of claim 8 , wherein
the housing further includes a first inlet valve configured to open and close to respectively open and close the first inlet, and
in response to the connection path valve being open so that the connection flow path is open, the first inlet valve is closed so that the first inlet is closed.

10. The ventilation apparatus of claim 9 , wherein
in response to the connection path valve being open so that the connection flow path is open, the second blower is not driven.

11. The ventilation apparatus of claim 7 , wherein
at least a portion of the second inlet chamber is formed by the surface of the second housing, and at least a portion of the first outlet chamber is formed by the surface of the second housing,
the housing further includes a partition wall between the second inlet chamber and the first outlet chamber, and the partition wall defines at least a portion of the second inlet chamber inside the housing and at least a portion of the first outlet chamber inside the housing, and
the connection path valve is on the partition wall.

12. The ventilation apparatus of claim 7 , wherein
the second inlet chamber has a larger internal space than the first inlet chamber, the first outlet chamber, and the second outlet chamber.

13. The ventilation apparatus of claim 3 , wherein the first housing includes:
a first inlet portion forming a portion of the first inlet;
a first outlet portion forming a portion of the first outlet;
a second inlet portion forming a portion of the second inlet; and
a second outlet portion forming a portion of the second outlet, and

the second housing includes:
a first inlet portion forming another portion of the first inlet;
a first outlet portion forming another portion of the first outlet;
a second inlet portion forming another portion of the second inlet; and
a second outlet portion forming another portion of the second outlet, and

with respect to the up and down direction of the housing,
the first outlet portion of the first housing and the first outlet portion of the second housing are formed symmetrically,
the first inlet portion of the first housing and the first inlet portion of the second housing are formed symmetrically,
the second outlet portion of the first housing and the second outlet portion of the second housing are formed symmetrically, and
the second inlet portion of the first housing and the second inlet portion of the second housing are formed symmetrically.
