Air conditioning system

Abstract

An air conditioning system may include a return register configured to intake return air from a room; a supply register configured to output chilled air into the room; a blower in a cavity of the wall formed by two studs, a first panel of the wall, and a second panel of the wall; a heat transfer coil in the cavity and positioned to receive air from the blower and chill the air; and a vertical plenum in the cavity of the wall and arranged to carry chilled air from the heat transfer coil to the supply register.

What is claimed is: 
     
         1 . An air conditioning system for a structure, the air conditioning system comprising:
 a return register configured to intake return air from a room with a wall, the return register positioned at a first panel of the wall near a floor of the room;   a supply register configured to output chilled air into the room, the supply register positioned at the first panel of the wall above the return register and positioned near a ceiling of the room;   a blower in a cavity of the wall formed by two studs, a portion of the first panel, and a portion of a second panel of the wall, the blower configured to draw return air from the room through the return register;   a heat transfer coil in the cavity of the wall and positioned to receive air from the blower and chill the air; and   a vertical plenum in the cavity of the wall and arranged to carry chilled air from the heat transfer coil to the supply register.   
     
     
         2 . The air conditioning system of  claim 1 , further comprising a housing configured to contain the blower and the heat transfer coil, wherein the housing is contained within the cavity. 
     
     
         3 . The air conditioning system of  claim 2 , wherein the housing and the vertical plenum in the cavity of the wall are not visible by someone in the room and are not visible by someone outside of the room. 
     
     
         4 . The air conditioning system of  claim 2 , wherein the housing and the vertical plenum in the cavity of the wall are not visible by someone on either side of the wall. 
     
     
         5 . The air conditioning system of  claim 1 , wherein the portion of the first panel that partly forms the cavity is flush with an adjacent portion of the first panel of the wall, and the portion of the second panel that partly forms the cavity is flush with an adjacent portion of the second panel of the wall. 
     
     
         6 . The air conditioning system of  claim 1 , wherein the first panel of the wall and the second panel of the wall extends past the two studs. 
     
     
         7 . The air conditioning system of  claim 1 , wherein:
 the portion of the first panel does not extend into the room or extend away from the room relative to an adjacent portion of the first panel; and   the portion of the second panel does not extend toward the room or extend away from the room relative to an adjacent portion of the second panel.   
     
     
         8 . The air conditioning system of  claim 1 , wherein the first panel is a gypsum board. 
     
     
         9 . The air conditioning system of  claim 1 , wherein the portion of the first panel that partly forms the cavity includes a gypsum board wall finish on a surface facing the room. 
     
     
         10 . The air conditioning system of  claim 1 , wherein second panel is a gypsum board or sheathing. 
     
     
         11 . The air conditioning system of  claim 1 , wherein the second panel includes a surface facing an environment external to the structure. 
     
     
         12 . The air conditioning system of  claim 1 , wherein wall is an interior wall of the structure. 
     
     
         13 . The air conditioning system of  claim 1 , wherein the supply register comprises vanes configured to direct the chilled air at an upward angle toward the ceiling to induce the Coanda effect such that the chilled air propagates along a surface of the ceiling. 
     
     
         14 . The air conditioning system of  claim 1 , wherein the studs are part of a standard frame structure for walls of habitable structures. 
     
     
         15 . The air conditioning system of  claim 14 , wherein the studs are arranged according to a standard frame structure for walls of habitable structures. 
     
     
         16 . The air conditioning system of  claim 14 , wherein the two studs of the wall are spaced apart from each other according to standard dimensions of the standard frame structure for walls of habitable structures. 
     
     
         17 . The air conditioning system of  claim 1 , further comprising:
 a heat pump exterior to the cavity; and   a line carrying water from the heat pump to the heat transfer coil.   
     
     
         18 . The air conditioning system of  claim 17 , wherein the heat pump is positioned exterior to the structure. 
     
     
         19 . The air conditioning system of  claim 1 , wherein the cavity does not contain a heat pump. 
     
     
         20 . The air conditioning system of  claim 1 , wherein the blower is configured to be serviceable through the return register.
