HIGH EFFICIENCY FLIPPING WINDOW-BRIDGE AIR CONDITIONERS AND HEAT PUMPS

Abstract

A combination of high efficiency ductless air conditioners and heat pumps installed in a window opening. A metal frame, mounted over the sill like a bridge, structurally links an indoor unit and outdoor unit. Flexible tubing inside the frame operationally connects the units. The outdoor unit is flexibly connected to the frame so it can be flipped 90 degrees from a horizontal position to a downward vertical position and vice versa. Thereby the length of the outdoor unit is not limited by the dimensions of the window opening. Hence the outdoor unit can have a large condenser and coils with large surface to achieve high efficiency. The indoor unit is slidably connected to the frame so it can be slided towards or away from the outdoor unit. The frame is secured to the window opening via a security bar. The indoor unit further enhances efficiency through 3-side air return.

DETAILED DESCRIPTION

[0029] A detailed description is as follows:

[0030] In the first aspect, what is invented is ductless air conditioners and heat pumps installed in a window opening of a structure. As FIG. 1 shows, when installing ductless air conditioners and heat pumps in the window opening of a structure, a metal frame (3) is used to link the indoor unit (1) and the outdoor unit (2) together. One feature distinguishes the current invention from prior art is that the outdoor unit (2) is flexibly connected to the metal frame (3) so that it (2) can be flipped 90 degrees from a horizontal position to a downward vertical position and vice versa. FIG. 1 shows the outdoor unit (2) in a horizontal position while it (2) is connected with the indoor unit (1) via the metal frame (3). FIG. 2 illustrates when installing ductless air conditioners and heat pumps in the window opening of a structure, the outdoor unit (2) can be pushed through the window opening in a horizontal position. FIG. 3 pictures how the outdoor unit (2) can be flipped 90 degrees from a horizontal position to a downward vertical position and vice versa. FIG. 4A, FIG. 4B and FIG. 4C demonstrate from another perspective how the outdoor unit (2) can be flipped 90 degrees from a horizontal position to a downward vertical position and vice versa. Once the outdoor unit (2) is outside of the window opening and flipped to a downward vertical position, as FIG. 5 illustrates, it (2) can be secured to the metal frame (3) while it (2) remains in the downward vertical position; thereby., the metal frame (3) is mounted over the window sill like a bridge with the outdoor unit (2) outside of the structure and the indoor unit (1) inside of the structure.

[0031] Another feature differentiates the current invention from prior art is that the indoor unit (1) is slidably connected to the metal frame (3) so that the indoor unit (1) can be slided err opposite directions towards or away from the outdoor unit (3). FIG. 1 and FIG. 3 show how the indoor unit (1) is slidably connected to the metal frame (3) so that the distance between the indoor unit (1) and the outdoor unit (2) can he increased or decreased accordingly. One advantage of this slidable feature of the indoor unit (1) is that the distance between the indoor unit (1) and the outdoor (2) can be easily adjusted to fit the depths of different wall structures. After the outdoor unit (2) is outside of the structure and secured to the metal frame (3) in a downward vertical position, the indoor unit (1) can be slidably adjusted towards or away from the outdoor unit (2) until, as FIG. 6 shows, the indoor wall holdings (4) and the outdoor wall holdings (5) can rest tightly against the wall structure. If the exterior surface is uneven, the length of the protruding portion of the outdoor wall holdings (5) can be adjusted, as demonstrated by FIG. 3, so that the outdoor wall holdings (5) can rest tightly against the exterior wall (FIG. 6).

[0032] Another feature differentiates the current invention from prior art is that the metal frame (3) has a security bar (6) affixed on it (FIG. 7A and FIG. 7B) and the metal frame (3) is secured by the security bar (6) to the interior of the window frame (FIG. 8) or the interior of the structure (FIG. 9). FIG. 7B shows the security bar (6) is slidable in opposite directions on the metal frame (3) and expendable/retractable in length so that the security bar (6) can be affixed against the interior of the window frame or the interior of the structure. FIG. 8 shows the security bar (6) is affixed over the window frame, thereby securing the metal frame (3). FIG. 9 pictures the security bar (6) is affixed against the interior wall, thereby securing the metal frame (3).

[0033] An additional feature of the present invention is that, as FIG. 10 and FIG. 11 show, flexible tubing (7) is placed inside of the metal frame (3) and operationally connects the indoor unit (1) with the outdoor unit (2).

[0034] Yet another feature distinguishes the present invention from prior art is that the indoor unit (1) has 3-side air return. FIG. 10 pictures the indoor unit (1) has A-shaped coils (8) with 3-side air return in the front, in the back and at the bottom of the unit. FIG. 11 shows, as an alternative, the indoor unit (1) has U-shaped coils (10) with 3-side air return on the top, in the back and at the bottom of the unit. FIG. 10 shows that A-shaped coils (8) have a drain pump (9) and FIG. 11 demonstrates that U-shaped coils (10) have direct draining (11).

[0035] In the second aspect, what is invented is a method to install ductless air conditioners and heat pumps in a window opening of a structure. The method consists of the following: as FIG. 1 shows, connecting the indoor unit (1) with the outdoor unit (2) together via a metal frame (3); as FIG. 2 demonstrates, mounting the metal frame (3) over the sill of the window opening with the outdoor unit (2) towards the window opening and pushing the outdoor unit (2) through the window opening while the outdoor unit (2) is in a horizontal position so that the length of the outdoor unit (2) is not limited by the dimensions of the window opening; as FIG. 3 and FIG. 4 picture, when the outdoor unit (2) is outside of the structure, flipping the outdoor unit (2) 90 degrees from the horizontal position to a downward vertical position, so that, as FIG. 5 shows, the indoor unit (1) is inside of the structure, the outdoor unit (2) is outside of the structure and the metal frame (3) is mounted over the window sill like a bridge; securing the outdoor unit (2) to the metal frame (3) as the outdoor unit (2) remains in the downward vertical position; sliding the indoor unit (1) towards or away from the outdoor unit (3) until, as FIG. 6 shows, the indoor wail holdings (4) and the outdoor wail holdings (5) can rest tightly against the surfaces of the structure; as FIG. 7B demonstrates, adjusting the security bar (6) by sliding it (6) back and forth on the metal frame (3) and by extending or retracting it (6) so that the security bar (6) can be affixed to the interior of the window frame (FIG. 9) or the interior of the structure (FIG. 10) and thereby securing the metal frame (3); if the exterior wall is uneven, adjusting the length of the protruding portion of the outdoor wall holdings (5), as FIG. 3 shows, so that the outdoor wall holdings (5) can rest tightly against the exterior of the structure. What is claimed is:
