Abstract:
1. A gas-fired air conditioning furnace, comprising: a plurality of cavity burners configured to combust an air-fuel mixture at least partially within an interior space of the cavity burners, the cavity burners comprising a substantially cylindrical tubular shape wherein the cavity burners comprises a plurality of perforations in a wall of the cavity burners, the plurality of perforations being configured to receive the air-fuel mixture therethrough; a plurality of heat exchangers configured to receive the air-fuel mixture from the cavity burners and to transfer heat from the air-fuel mixture to an airflow associated with an exterior of the heat exchangers; and an inlet tube at least partially located within a path of the airflow and configured to at least partially receive the cavity burners; wherein the outputs of the plurality of cavity burners are combined in a post-combustion chamber and wherein the output of the post-combustion chamber feeds the plurality of heat exchangers.
