Abstract

The present disclosure relates to air conditioning systems and methods. An aspect of the present disclosure is a device that includes a housing having an external surface and defining an interior volume, a heat exchanger positioned within the interior volume, a fluid line partially positioned within the interior volume, a sleeve extending from the external surface and terminating at a distal end of the sleeve, and a fluid connector. The sleeve has an outside wall spanning a length of the sleeve and defining an internal cavity, the fluid connector is positioned at or near the distal end, a portion of the fluid line is positioned within the internal cavity, and the fluid line provides a fluid connection between the heat exchanger and the fluid connector.

First claim

What is claimed is:

1. A system comprising:
a first unit comprising:
a first housing having a first external surface and defining a first interior volume;
a first heat exchanger positioned within the first interior volume;
a first fluid line partially positioned within the first interior volume;
a sleeve extending from the first external surface and terminating at the distal end, and
a first part of a fluid connector, wherein:
the sleeve has an outside wall spanning a length of the sleeve and defining an internal cavity,
the first part of the fluid connector is positioned within the internal cavity, and
the first fluid line provides a fluid connection between the first heat exchanger and the first part of the fluid connector;
a second unit comprising:
a second housing having a second external surface and defining a second interior volume;
a second heat exchanger positioned within the second interior volume;
a second fluid line positioned within the second interior volume;
a channel extending into the second interior volume from the second external surface; and
a second part of the fluid connector positioned within the channel, wherein:
the second fluid line provides a second fluid connection between the second heat exchanger and the second part of the fluid connector, wherein:
the channel comprises an outside wall,
the outside wall comprises a receiving hole,
the inside wall comprises an arrest mechanism,
the sleeve is positioned within the channel,
the sleeve has a first position, wherein the arrest mechanism is positioned outside of the receiving hole such that the sleeve is movable in a direction parallel to the length, and
the sleeve has a second position, wherein the arrest mechanism is positioned within the receiving hole such that the sleeve is not movable in the direction parallel to the length, and the first part and the second part are physically connected to form a liquid seal that allows a fluid to be transferred between the first heat exchanger and the second heat exchanger.

2. A method comprising:
inserting a sleeve of a first unit through a hole positioned in a wall having a first surface and a second surface, such that a distal end of the sleeve protrudes from the second surface of the wall;
securing the first unit to the wall by fastening a locking mechanism to the distal end;
placing the distal end in a channel that penetrates into a first surface of a housing of a second unit;
moving the second unit to a desired position relative to the wall by moving the distal end into the channel; and
securing the second unit to the first unit using at least one arrest mechanism positioned at least within the channel or on the sleeve, wherein:
securing the second unit to the first unit provides a fluid connection between the first unit and second unit.

3. The method of claim 2 , further comprising:
before the inserting, forming the hole in the wall, such that the hole passes completely through a thickness of the wall.

4. The method of claim 3 , wherein:
the forming produces a hole that is positioned perpendicular relative to at least one of the first surface of the wall or the second surface of the wall.

5. The method of claim 2 , further comprising:
prior to the inserting, placing a first gasket around the sleeve.

6. The method of claim 2 , further comprising:
prior to the placing the distal end in the channel, placing a second gasket around the distal end.

7. The method of claim 2 , further comprising:
prior to the inserting, attaching a securement plate, the securement plate comprising a hole passing through the securement plate, to the second surface of the wall, wherein:
the inserting the sleeve further comprises inserting the sleeve through the hole of the securement plate.

8. The method of claim 2 , wherein:
the fastening the locking mechanism comprises at least one of threading or ratcheting the locking mechanism onto the distal end of the sleeve.
