| A vapor generator for use in, for example, an absorption type water cooler or heater. The vapor generator having a burner section and a boiler section, the boiler section being constituted by an outer casing, an inner casing disposed in the outer casing, and a multiplicity of solution tubes attached in rows to the inner surfaces of wall of the inner casing so as to extend substantially vertically. The interior of the tubes is in communication with a space accommodating a medium to be heated and defined between the inner casing and outer casing. A multiplicity of fins are attached to the inner surfaces of walls of the inner casing in the area around the flame formed by the burner section so as to increase the rate of heat transfer to the medium in the above-mentioned space from the gas in the combustion chamber. The axis of each of the solution tubes in a second row is offset from the line which extends in parallel with the flow of gas from the midst of the gap between two adjacent solution pipes in a first row located upstream from the second row as viewed in the direction of flow of gas, so that overheating of the central portion of each solution tube in the second row is avoided advantageously. | ||||||
| 182 | Gas/electric operated absorption refrigerator having automatic flame detection and restart capability with visual indication of operating status | US521189 | 1983-08-08 | US4487030A | 1984-12-11 | Randy E. Carter; Ernst R. Schmidt |
| An absorption refrigerator having a generator selectively heated by an electrically operated resistance heater or a flammable gas operated burner. In the gas mode of operation, a monitor electrode positioned above the gas burner automatically senses the absence of the burner flame and commences a restart sequence to reignite the burner. If reignition fails or the burner cannot be ignited within a predetermined time, further ignition attempts are inhibited and an indicator lamp on the front of the refrigerator enclosure above the freezer door provides a visual indication that cooling is not being supplied to the refrigerator. Different colored visual indicators are also provided to show that the refrigerator is being operated by gas or electricity. In another embodiment, the refrigerator may be selectively operated from alternating current, direct current or flammable gas, with colored indicator lamps showing the type of power source used. | ||||||
| 183 | Method and generator unit of an absorption heat pump system for separating a rich liquor into a refrigerant and a solution low in refrigerant content | US796493 | 1977-05-12 | US4127993A | 1978-12-05 | Benjamin A. Phillips |
| A generator unit of an absorption heat pump system having a plurality of vertical tubular conduits around the reservoir zone in the lower portion of the generator unit, each conduit having a lower opening for drawing rich liquor from the reservoir portion. Heat is transferred from an external source into the vertical conduits. A method of separating rich liquor into refrigerant vapor and weak liquor including drawing rich liquor into vertical tubular conduits at a temperature at which bubbles of refrigerant vapor are forming in the rich liquor, heating the rich liquor in the vertical conduits thereby increasing the formation of refrigerant bubbles, driving the rich liquor upward in the vertical conduits with increasing speed by the vapor lift action of refrigerant bubbles and separating the fluid coming out of the vertical conduits into the refrigerant vapor and weak liquor. | ||||||

| A burner unit for gas appliances, more especially gas operated refrigerators, for use in place where an explosive gas or vapour may be encountered, comprises a burner located within a casing having an air intake covered by a fine mesh, and ignition means for the burner also located within the casing but operable from outside the casing.

| 185 | Compact heating and cooling system | US48446074 | 1974-06-28 | US3907025A | 1975-09-23 | MALCOSKY NORMAN D; MCLEAN RONALD H; SINGH KANWAL N; AUH CHUNG M |
| A compact absorption refrigeration unit has a central mounting core containing a generator about which substantially all of the components of the refrigeration system are mounted in a predetermined configuration. The generator has heat transfer fins secured to its surface which have a predetermined configuration that allows the fins and generator to absorb heat at the optimum rate at which heat can be transferred thereto without damage to the fins. The unit also includes an evaporator having a centrally positioned reservoir and a helical passageway providing a flow path for a heat exchange medium and containing a fluted helical heat exchanger tube which provides a countercurrent refrigerant, thereby to chill said heat exchange medium. In one embodiment of the invention the unit is provided with a compact boiler for use in heating the heat exchange medium, thereby permitting the unit to be selectively operated for both heating and cooling.

| The burner of a gas refrigerator reduces the temperature by burning gas received from a gas control valve which is opened by the membrane capsule of a thermostat, or closed by a spring. The membrane capsule is connected by a snap spring disc with the gas control valve so that the valve is not slowly opened and closed by the membrane capsule and spring, but rapidly shifted by the snap spring disc between the open and closed positions.

| 187 | Horizontal firing of generator in absorption refrigerator | US3750421D | 1972-07-21 | US3750421A | 1973-08-07 | MERRICK R |
| A heat exchanger, such as a vertically disposed cylindrical generator in an absorption refrigeration appliance, is heated by means of a horizontal flow of hot combustion products from a gas burner tube which is disposed parallel to the generator thereby reducing the height of the appliance.
