专利汇可以提供Gas-operated refrigerator having sealed combustion system专利检索，专利查询，专利分析的服务。并且A heat-operated refrigerator heated by a gas burner and a heating flue associated therewith is disposed in a space having an apertured exterior side wall. The heating flue and burner form parts of a sealed combustion system which includes a first conduit for supplying all of the combustion supporting air to the burner to form a combustible gas mixture with gas supplied thereto and a second conduit for withdrawing all of the flue gases from the upper end of the flue. The ends of the first and second conduits removed from the burner and flue, respectively, are open and terminate in the apertured side wall, the open end of the first conduit serving as an inlet for ambient air and the open end of the second conduit serving as an outlet for flue gases. The flue gas outlet is disposed above the air inlet. The air inlet and flue gas outlet have the same cross-sectional areas and are flush with the outer surface of the exterior wall.，下面是Gas-operated refrigerator having sealed combustion system专利的具体信息内容。
1. In structure defining a space having an exterior side wall, heat-operated refrigeration apparatus disposed in said space, said refrigeration apparatus comprising a heat receiving part having a heating flue, a gas burner coacting with said flue, means for supplying combustible gas to said burner, first conduit means for conducting combustion supporting air to said burner, second conduit means for conducting flue gases from the upper end of said flue, said first and second conduit means and burner and flue being constructed and formed to provide a sealed combustion system in which all of the combustion supporting air is supplied to said burner through said first conduit means and all of the flue gases are withdrawn from said flue through said second conduit means, said exterior side wall being apertured, the end of said first conduit means removed from said burner being open and terminating in said apertured side wall and serving as an inlet for ambient air, the end of second conduit means removed from said flue being open and terminating in said apertured side wall and serving as an outlet for flue gases, said flue gas outlet being disposed above said air inlet, and said air inlet and flue gas outlet having substantially the same cross-sectional areas and being substantially flush with the outer surface of said exterior side wall, said first conduit means including a vertically disposed section extending upward from said air inlet and said second conduit means including a vertically disposed section extending downward to said flue gas outlet.
2. Apparatus as set forth in claim 1 in which said apertured side wall has an opening therethrough and at least the vertically disposed section of said second conduit is in the vertical plane of said wall opening.
3. Apparatus as set forth in claim 1 which includes means defining two vertically extending spaces separated by partitioning, one of said spaces serving as the vertically disposed section of said first conduit and the other of said spaces serving as the vertically disposed section of said second conduit.
4. Apparatus as set forth in claim 3 in which said first conduit includes a horizontal section and said second conduit includes a horizontal section, each of said horizontal sections being in communication with a different one of said vertically extending spaces.
5. Apparatus as set forth in claim 1 which comprises a rectangular-shaped casing at the apertured side wall, said casing having partitioning defining said vertically extending sections of said first and second conduits, a wall of said casing flush with the outer surface of said exterior side wall being apertured to provide said air inlet and flue gas outlet at opposing sides of said partitioning.
6. Apparatus as set forth in claim 5 in which said partitioning comprises a zig-zag member having a vertical portion and horizontal portions Projecting in opposite directions from said vertical portion at the top and bottom thereof, the air inlet and flue gas outlet being in abutting relation below and above said bottom horizontal portion at said apertured side wall of said casing.
7. Apparatus as set forth in claim 1 in which said vertically disposed section of said second conduit is flush with the outer surface of said exterior side wall and said vertically disposed section of said first conduit is at the rear of said vertically disposed section of said second conduit.
8. Apparatus as set forth in claim 1 in which said vertically disposed sections of said first and second conduits are both flush with the outer surface of said exterior side wall with said vertically disposed section of said first conduit below said vertically disposed section of said second conduit.
9. In structure defining a space having an exterior side wall, heat-operated refrigeration apparatus disposed in said space, said refrigeration apparatus comprising a heat receiving part having a heating flue, a gas burner coacting with said flue, means for supplying combustible gas to said burner, first conduit means for conducting combustion supporting air to said burner, second conduit means for conducting flue gases from the upper end of said flue, said first and second conduit means and burner and flue being constructed and formed to provide a sealed combustion system in which all of the combustion supporting air is supplied to said burner through said first conduit means and all of the flue gases are withdrawn from said flue through said second conduit means, said exterior side wall being apertured, the end of said first conduit means removed from said burner being open and terminating in said apertured side wall and serving as an inlet for ambient air, the end of said second conduit means removed from said flue being open and terminating in said apertured side wall and serving as an outlet for flue gases, said flue gas outlet being disposed above said air inlet, and said air inlet and flue gas outlet having substantially the same cross-sectional areas and being substantially flush with the outer surface of said exterior side wall, each of said first and second conduit means including first vertically disposed portions at the immediate vicinities of said air inlet and flue gas outlet and second portions extending from said first portions to said burner and flue, respectively, the cross-sectional areas of said air inlet and flue gas outlet being at least as great as the cross-sectional areas of said first vertically disposed portions of said first and second conduit means, and the cross-sectional areas of said first vertically disposed portions being greater than the cross-sectional areas of the second portions of said first and second conduit means.
10. Apparatus as set forth in claim 9 in which the first and second portions of each of said first and second conduit means is of inverted U-shape.
11. Apparatus as set forth in claim 9 in which the cross-sectional areas of said first vertically disposed portions of said first and second conduit means are at least equal to the cross-sectional area of said flue.
