Abstract

Air conditioner units, bulkhead assemblies, and methods for operating air conditioner units are provided. A bulkhead assembly includes a bulkhead which includes a first sidewall, a second sidewall, and a rear wall extending laterally between the first sidewall and the second sidewall. The rear wall includes an indoor facing surface and an opposing outdoor facing surface. The bulkhead assembly further includes a vent aperture defined in the rear wall, and a vent door movable between an open position and a closed position, wherein in the open position the vent door permits air flow through the vent aperture and in the closed position the vent door inhibits air flow through the vent aperture. The bulkhead assembly further includes a drive assembly connected to the vent door and operable to selectively move the vent door between the open position and the closed position.

First claim

What is claimed is:

1. An air conditioner unit, comprising:
an outdoor heat exchanger;
an indoor heat exchanger;
a bulkhead disposed between the outdoor heat exchanger and the indoor heat exchanger along a transverse direction, the bulkhead comprising a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a rear wall extending laterally between the first sidewall and the second sidewall, the rear wall comprising an indoor facing surface and an opposing outdoor facing surface;
a vent aperture defined in the rear wall;
a vent door movable between an open position and a closed position, wherein in the open position the vent door permits air flow through the vent aperture and in the closed position the vent door, inhibits air flow through the vent aperture;
a drive assembly connected to the vent door and operable to selectively move the vent door between the open position and the closed position;
a first humidity sensor and a second humidity sensor, the first humidity sensor positioned in an indoor portion and configured to measure a contemporary indoor humidity within the indoor portion, the second humidity sensor positioned in an outdoor portion and configured to measure a contemporary outdoor humidity within the outdoor portion; and
a controller in communication with the drive assembly, the controller operable to actuate the drive assembly and move the vent door between the open position and the closed position,
wherein the controller is further operable to
determine a difference between the contemporary outdoor humidity and the contemporary indoor humidity,
move the vent door to the open position in response to a determination of the difference within a predetermined humidity range, and
move the vent door to the closed position in response to a determination of the difference outside of the predetermined humidity range.

2. The air conditioner unit of claim 1 , further comprising a first temperature sensor and a second temperature sensor, the first temperature sensor positioned in an indoor portion and configured to measure an indoor temperature, the second temperature sensor positioned in an outdoor portion and configured to measure an outdoor temperature.

3. The air conditioner unit of claim 2 , wherein the controller is operable to move the vent door to the open position when a difference between the outdoor temperature and the indoor temperature is within a predetermined temperature range.

4. The air conditioner unit of claim 3 , wherein the predetermined temperature range is user-selectable from a plurality of predetermined temperature ranges.

5. The air conditioner unit of claim 1 , wherein the predetermined humidity range is user-selectable from a plurality of predetermined humidity ranges.

6. The air conditioner unit of claim 1 , further comprising a filter positioned in alignment with the vent aperture.

7. The air conditioner unit of claim 1 , wherein the bulkhead further comprises an air diverter extending laterally between the first sidewall and the second sidewall.

8. The air conditioner unit of claim 1 , further comprising a blower fan and a heating unit each disposed at least partially within an interior of the bulkhead.

9. A bulkhead assembly for an air conditioner unit, the bulkhead assembly comprising:
a bulkhead, the bulkhead comprising a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a rear wall extending laterally between the first sidewall and the second sidewall, the rear wall comprising an indoor facing surface and an opposing outdoor facing surface;
a vent aperture defined in the rear wall;
a vent door movable between an open position and a closed position, wherein in the open position the vent door permits air flow through the vent aperture and in the closed position the vent door inhibits air flow through the vent aperture;
a drive assembly connected to the vent door and operable to selectively move the vent door between the open position and the closed position;
a first humidity sensor and a second humidity sensor spaced apart from the first humidity sensor by the bulkhead along a transverse direction, the first humidity sensor being configured to measure a first contemporary humidity, the second humidity sensor being configured to measure a second contemporary humidity; and
a controller in communication with the drive assembly, the controller operable to
determine a difference between the first contemporary humidity and the second contemporary humidity,
move the vent door to the open position in response to a determination of the difference within a predetermined humidity range, and
move the vent door to the closed position in response to a determination of the difference outside of the predetermined humidity range.
