Abstract
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.
