Combination compressor-condenser

Claim 2

An integral compressor and condenser assembly for automobile air conditioning systems comprising: a drive shaft mounted centrally in a compressor housing; compressing means within said housing operably connected to said shaft for pressurizing refrigerant when said shaft is rotated; an annular band member spaced radially outward from said compressor housing and joined along its opposite edges to said housing which forms a condenser cavity therebetween for cooling refrigerant discharged from said compressor means; a discharge port extending through the compressor housing and into said condenser cavity to pass relatively warm refrigerant into said condenser cavity; a cylindrical shroud member encircling said annular band member forming an axially extending air passage which is separated from refrigerant within said compressor cavity by said annular band member whereby air passing through said air passage absorbs heat from refrigerant in said condenser cavity; a combination pulleyfan member attached to the end of said shaft which extends from said housing adapted to be rotated by the automobile engine; said pulley-fan member having air inlets in its front end which extend through the member in a substantially axial direction which are aligned with said annular air passage inside said shroud; said air inlets being circumferentially located and separated by radially directed wall portions of said pulley-fan member to cause air to be drawn into said air inLets and discharged between said shroud and said band member for cooling refrigerant in said adjacent condenser cavity.

Claim 3

An integral compressor and condenser assembly for an automobile air conditioning system comprising: a drive shaft mounted centrally in a compressor housing; compressing means within said housing operably connected to said shaft for pressurizing refrigerant as said shaft is rotated; an annular band member spaced radially outward from said compressor housing and joined along its opposite edges to said housing which forms a condenser cavity therebetween for cooling refrigerant discharged from said compressor means; a discharge port extending through the compressor housing and into said condenser cavity to pass relatively warm refrigerant into said condensing cavity; a cylindrical shroud member encircling said band member and forming an axially extendng air passage which is separated from refrigerant in said condenser cavity by said annular band member whereby air passing through said air passage absorbs heat from refrigerant in said condenser cavity; a corrugated fin-strip member within said condenser cavity for increasing the heat transferred from said refrigerant through said annular band member; a corrugated fin-strip member in said air passage between said band member and said air shroud for increasing the heat transferred from said band member to air in the air passage; a combination pulley-fan member attached to the end of said shaft which extends from said housing adapted to be rotated by the automobile engine; said pulley-fan member having air inlets in its front end which extend through the member in a substantially axial direction which are aligned with said annular air passage inside said shroud; said air inlets being circumferentially located and separated by radially directed wall portions of said pulley-fan member to cause air to be drawn into said air inlets and discharged between said shroud and said band member for cooling refrigerant in said adjacent condenser cavity.

Claim 4

An integral compressor and condenser assembly for an automobile air conditioning system comprising: a drive shaft mounted centrally in a compressor housing; compressing means within said housing operably connected to said shaft for pressurizing refrigerant as said shaft is rotated; an annular band member spaced radially outward from said compressor housing and joined along its opposite edges to said housing which forms a condenser cavity therebetween for cooling refrigerant discharged from said compressor means; a discharge port extending through the compressor housing and into said condenser cavity to pass relatively warm refrigerant into said condensing cavity; a cylindrical shroud member encircling said band member and forming an axially extendng air passage which is separated from refrigerant in said condenser cavity by said annular band member whereby air passing through said air passage absorbs heat from refrigerant in said condenser cavity; a corrugated fin-strip member within said condenser cavity for increasing the heat transferred from said refrigerant through said annular band member; a corrugated fin-strip member in said air passage between said band member and said air shroud for increasing the heat transferred from said band member to air in the air passage; a combination pulley-fan member attached to the end of said shaft which extends from said housing adapted to be rotated by the automobile engine; said pulley-fan member having air inlets in its front end which extend through the member in a substantially axial direction which are aligned with said annular air passage inside said shroud; said air inlets being circumferentially located and separated by radially directed wall portions of said pulley-fan member to cause air to be drawn into said air inlets and discharged between said shroud and said band member for cooling refrigerant in said adjacent condenser cavity.

Claim 5

An automotive air conditioning system comprising: an integral compressor-condenser assembly having a refrigerant inlet for introducing lower pressure refrigerant to the compressor and an outlet for discharging relatively higher pressure refrigerant; expansion means connected to said outlet for expanding refrigerant from a high pressure to a lower pressure; an evaporator fluidly connected to said expansion means and in contact with air flowing into the automobile passenger compartment for transmitting heat from the air to refrigerant in said evaporator whereby it is vaporized subsequent to returning to the compressor; said compressor-condenser assembly including a cylindrical compressor housing encircled by a radially outwardly spaced annular band member whose opposite edges are attached to said housing to form a compressor cavity therebetween; means fluidly connecting said compressor to the compressor cavity for transmitting pressurized and warmed refrigerant; an annular air shroud encircling said band member and forming an air passage therebetween for passing air in heat transfer relationship with the annular band member whereby heat is transmitted from refrigerant in the compressor cavity to air in the air passage; a combination pulley-fan assembly rotatable with said compressor and having axially extending air inlets aligned with said air passage; said air inlets being circumferentially spaced and separated by radial wall portions to form fan blades to pass air into said air inlet and between said annular band member and said air shroud; corrugated fin-strips in said condenser cavity and in said air passage for efficiently transmitting heat from refrigerant through said annular band member to air in said air passage.
