| An absorption chiller wherein refrigerant such as water is dissolved in liquid absorbent such as lithium bromide to form a solution of refrigerant in the absorbent. The absorption chiller includes a generator 4 to boil-off the water refrigerant from the lithium bromide absorbent to separate the water as stream from the lithium bromide. The generator 4 comprises an upper tank 42 and a lower tank 36 interconnected by plain heat exchange tubes 38A and finned heat exchange tubes 38B. Two thermo-syphon tubes 58A and 58B also interconnect and open into each of the tanks containing the aforesaid solution which flows from the upper tank 42 through the tubes 58A, 58B to the lower tank 36 and from the lower tank to the upper tank through the heat exchange tubes 38A, 38B wherein aforesaid boil-off takes place. The heat exchange tubes are disposed in cross-flow relation to hot heating gases or products of combustion flowing in direction X through a combustion chamber 46, from a fuel gas pre-mix package burner 50, the heat exchange tubes being in said combustion chamber. Heat insulation material separates the thermo-syphon tubes from the combustion chamber. Steam leaves the upper tank through an outlet 72 and concentrated lithium bromide through an outlet 70. The weak solution of lithium bromide is introduced into the upper tank through an inlet opposite the upper end of thermo-syphon tube 58A. | ||||||

In an absorption type chiller heater, a generator (1) is heated in order to heat a refrigerant-mixed solution to generate refrigerant vapor. This heating is generally carried out by causing high-temperature combustion gas to flow in contact with heat transfer fins (1a), which are provided on the periphery of the generator (1). The aforesaid burner uses a burner (8) of liquid-fuel combustion structure to produce a longer flame as compared to that of a gas burner. The extremity of the lengthened flame coming into contact with the heat transfer fins can cause problems such that the fins are locally overheated to burn out. Accordingly, the present invention arranges a flame buffer plate (13) between the liquid fuel burner and the heat transfer fins and provides a curved flame channel. This forms a curved flame, whereby the flame, despite of its great length, is kept from its extremity coming into contact with the heat transfer fins. |

The invention refers to an arrangement at a refrigerator cabinet (10) having an absorption refrigerating apparatus (16,18) operated by a heating cartridge (40) from at least one electric current source or by a gas burner (38). The arrangement shows a control apparatus (74) which automatically starts the gas burner (38) when the supply of current to the heating cartridge (40) ceases. The refrigerating apparatus (18) is with exception of its evaporator (16) enclosed in a heat insulated chamber (20) through which surrounding air circulates for cooling of the refrigerating apparatus (18). In order to prevent the refrigerant in the refrigerating apparatus from freezing to plugs at low temperature of the surrounding air, which plugs put the refrigerating apparatus out of function, means (86) are arranged to limit the air circulation through the chamber (20) and a temperature sensing means (80) is located in the chamber for breaking the current to the heating cartridge (40) at a certain low temperature in the chamber (20) so that the gas burner (38) is put into operation. |

Die Erfindung betrifft eine Heizungsanlage mit einer Absorptionswärmepumpe, deren Austreiber durch einen mit überstöchiometrischer Luftvormischung arbeitenden Gasbrenner beheizt wird, dessen Voll- und Teillastwirkungsgrad gleichermaßen sehr groß sind und dessen Abgas einen sehr geringen NOx-Gehalte aufweist. Das Brenngas-Verbrennungsluft-Gemisch strömt aus mindestens einem Mischrohr (2) in eine Mischkammer (3) und verbrennt an einer durch reiche Lösung gekühlten Brennerplatte (4), die in einem Abstand von weniger als 50 mm zum Austreiber (17) angeordnet ist. Für senkrecht stehende Austreiber wird bevorzugt ein Brenner verwendet, dessen Brennerplatte den Austreiber in einer solchen Höhe vom Austreiberboden konzentrisch umgibt, daß nur der mittlere Austreiberbereich direkt beheizt wird. Im Abgasweg sind hinter dem Austreiber vorzugsweise zwei Wärmetauscher zur Nutzung der Abgaswärme einschließlich der Kondensationswärme angeordnet. Durch die erfindungsgemäße Anordnung eines zweiten Brenners (19) vor dem ersten Wärmetauscher (9), der bei Unterschreiten einer unteren Grenztemperatur an Stelle des Brenners für die Austreiber-Beheizung in Betrieb genommen wird, kann diese Heizungsanlage den Wärmebedarf auch bei niedrigsten Außentemperaturen decken. |

| An ignition containment system is provided for absorption refrigeration systems. The system encloses the burner area to contain an inadvertent ignition of gases that may have escaped from the refrigerant tubing or elsewhere. By containing a potential fire or vapor leak, the system can substantially mitigate the spread of a fire to other nearby combustible materials, further damage to the appliance, and fire or smoke damage to property or materials beyond the appliance. The ignition containment system can also include an electrical detection device that can indicate an abnormal rise in temperature, a presence of foreign material, or the presence of ignitable gases in the contained or encapsulated ignition chamber. Detection of any one of the above can trigger a termination of the ignition source. | ||||||
