These are some improvements to further improve the heat transfer of a Window A/C unit, mainly focused on better seperation between the hot and cold side:
-Have a metal break in the A/C housing from between hot and cold side, to better isolate heat on the hot side from conducting into the cold side.
-Add a highly heat reflective insulation sheet on the hot side of the styrofoam wall that seperates the hot and cold air side.
These two improvements can raise the efficiency of the Window A/C without losing price point.

Problem with a materials break in the case/frame is a materials break in the case/frame. Compressors are *heavy* and window A/C's connect to the windowframe at the front. All up with the reflective thing, if it would be an improvement. |

With a bit of work you could mount the body of the A/C on the outside wall, then just attach in/out airhoses to go into the house. Sorta like mini-central-air. Do the control thing wirelessly. |

Much better to insulate the building than go for minimal gains on the a/c unit itself. |

My recent trip back to England reminded me of
something. Doors fit. A tremendous upside of building in
brick is that there is minimal warping/shrinking/swelling.
Subsequently, English doors fit. All my home doors have
alternate sticky bits and big gappy bits. Then there are
basements and floors don't have any carpets (mixed
feelings about that). So all my cold AC air falls through
the floor, around the doors or is heated up and ejected
by the clothes drier. Similarly, the central air outlet for
the small bathroom is the same size as the medium
bedroom. So the bathroom's freezing, the bedroom is OK,
the and the waste heat from 3 apartments worth of
poorly insulated water heaters keeps the basement from
being arctic. It's a silly system. I'd be putting a window AC
unit in, only the immovable metal bars on the window
prevent that. There really needs to be a better popular
understanding of insulation in the US. |

to restate the idea as an ascii graphic. I think it would work |
