The wall sleeve is positioned in an opening on the side of a building and defines an intake aperture and an exhaust aperture that fluidly couple the outdoor portion to the room. An intake fan assembly is mounted to the wall sleeve over the intake aperture for selectively urging a flow of make-up air into the room and an exhaust fan assembly if mounted to the wall sleeve over the exhaust aperture for selectively urging a flow of exhaust air out of the room. ## Claims ### Claim 1 A packaged terminal air conditioner unit for conditioning air in a room, the package terminal air conditioner unit comprising: a bulkhead defining an indoor portion and an outdoor portion; a sealed system comprising a compressor, an indoor heat exchanger positioned within the indoor portion, an outdoor heat exchanger positioned within the outdoor portion, and an expansion device, the sealed system being operable to transfer thermal energy between the indoor portion and the outdoor portion; a wall sleeve configured for receiving at least a portion of the sealed system, the wall sleeve defining an intake aperture that fluidly couples the outdoor portion to the room; and an intake fan assembly mounted to the wall sleeve over the intake aperture for selectively urging a flow of make-up air into the room. ### Claim 2 (depends on 1) The packaged terminal air conditioner unit of claim 1, wherein the wall sleeve further defines an exhaust aperture that fluidly couples the outdoor portion to the room, the packaged terminal air conditioner unit further comprising: an exhaust fan assembly mounted to the wall sleeve over the exhaust aperture for selectively urging a flow of exhaust air out of the room. ### Claim 3 (depends on 2) The packaged terminal air conditioner unit of claim 2, wherein the intake aperture and the exhaust aperture are defined on opposite sides of the wall sleeve along a lateral direction. ### Claim 4 (depends on 1) The packaged terminal air conditioner unit of claim 1, wherein the wall sleeve is mountable within an opening in a building wall. ### Claim 5 (depends on 1) The packaged terminal air conditioner unit of claim 1, wherein the intake fan assembly comprises a plurality of muffin fans stacked adjacent each other in a fan housing. ### Claim 6 (depends on 1) The packaged terminal air conditioner unit of claim 1, wherein the intake fan assembly operates off 24 volts DC. ### Claim 7 (depends on 1) The packaged terminal air conditioner unit of claim 1, wherein the intake fan assembly is rated for a flow rate of greater than 40 cubic feet per minute. ### Claim 8 (depends on 1) The packaged terminal air conditioner unit of claim 1, wherein the intake fan assembly further comprises: at least one of an air filter or a bug screen. ### Claim 9 (depends on 1) The packaged terminal air conditioner unit of claim 1, further comprising: a flow regulating device for preventing air from passing through the intake fan assembly into the room when the intake fan assembly is off ### Claim 10 (depends on 9) The packaged terminal air conditioner unit of claim 9, wherein the flow regulating device comprises: one or more louvres for selectively opening or closing to regulate the flow of make-up air. ### Claim 11 A sleeve assembly for an air conditioner unit, the sleeve assembly comprising: a wall sleeve that at least partially defines an outdoor portion and a room, the wall sleeve defining an intake aperture that fluidly couples the outdoor portion to the room; and an intake fan assembly mounted to the wall sleeve over the intake aperture for selectively urging a flow of make-up air into the room. ### Claim 12 (depends on 11) The sleeve assembly of claim 11, wherein the wall sleeve further defines an exhaust aperture that fluidly couples the outdoor portion to the room, the sleeve assembly further comprising: an exhaust fan assembly mounted to the wall sleeve over the exhaust aperture for selectively urging a flow of exhaust air out of the room. ### Claim 13 (depends on 12) The sleeve assembly of claim 12, wherein the intake aperture and the exhaust aperture are defined on opposite sides of the wall sleeve along a lateral direction. ### Claim 14 (depends on 11) The sleeve assembly of claim 11, wherein the wall sleeve is mountable within an opening in a building wall. ### Claim 15 (depends on 11) The sleeve assembly of claim 11, wherein the intake fan assembly comprises a plurality of muffin fans stacked adjacent each other in a fan housing. ### Claim 16 (depends on 11) The sleeve assembly of claim 11, wherein the intake fan assembly operates off 24 volts DC. ### Claim 17 (depends on 11) The sleeve assembly of claim 11, wherein the intake fan assembly is rated for a flow rate of greater than 40 cubic feet per minute. ### Claim 18 (depends on 11) The sleeve assembly of claim 11, wherein the intake fan assembly further comprises: at least one of an air filter or a bug screen. ### Claim 19 (depends on 11) The sleeve assembly of claim 11, further comprising: a flow regulating device for preventing air from passing through the intake fan assembly into the room when the intake fan assembly is off ### Claim 20 (depends on 19) The sleeve assembly of claim 19, wherein the flow regulating device comprises: one or more louvres for selectively opening or closing to regulate the flow of make-up air.
