Abstract

Abstract An air conditioner including a cabinet located in a building space to be conditioned adjacent to a building wall having an opening, the cabinet having a pair of outside air inlets and an outlet communicating through the wall opening, and inferiorly located condenser in the cabinet in a path of cooling air between one inlet and the outlet, the cabinet having a room air inlet and a conditioned air outlet, and a superiorly located evaporator interposed in the path of fluid movement between the room air inlet and conditioned air outlet. The installation is uniquely advantageous for use in existing buildings without altering structure.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 129 words
An air conditioner for location in a building space to be conditioned and comprising a cabinet for location adjacent to a building wall extending across a single wall opening, said cabinet having an upper pair of inlets for receiving outside air through said wall opening and a lower outlet adjacent to said inlets for discharge of condenser air through said wall opening, a condenser in a lower cabinet region interposed in the path of fluid flow between one of said inlets and said outlet, said cabinet having a lower inside air inlet and an upper conditioned air outlet, an evaporator in said cabinet interposed in the path of fluid flow between said inside air inlet and conditioned air outlet, and air movement means for moving air along said paths.
Claim 2
Dependent Claim 129 words
An air conditioner for location in a building space to be conditioned and comprising a cabinet for location adjacent to a building wall extending across a single wall opening, said cabinet having an upper pair of inlets for receiving outside air through said wall opening and a lower outlet adjacent to said inlets for discharge of condenser air through said wall opening, a condenser in a lower cabinet region interposed in the path of fluid flow between one of said inlets and said outlet, said cabinet having a lower inside air inlet and an upper conditioned air outlet, an evaporator in said cabinet interposed in the path of fluid flow between said inside air inlet and conditioned air outlet, and air movement means for moving air along said paths.
Claim 3
Dependent Claim 36 words
