Abstract: A refrigerant leak mitigation sleeve includes a flexible sleeve body comprising bellow elements, wherein the flexible sleeve body includes a cavity configured to contain refrigerant fluid and the bellow elements are configured to expand or contract. The mitigation sleeve includes a tube clamp interface at a first end of the flexible sleeve body, wherein the tube clamp interface comprises a first diameter and is configured to receive a tube. The mitigation sleeve includes a sealing collar at a second end of the flexible sleeve body. The mitigation sleeve includes at the collar end a passageway for refrigerant leaks to be directed back into the HVAC equipment cabinet. The mitigation sleeve includes a gusset positioned between the sealing collar and the flexible sleeve body, wherein the gusset comprises stiffening ribs. The mitigation sleeve further includes a deformable engagement collar connected to the sealing collar on a side opposite to the gusset.

Abstract: A burner box assembly for a combustion air furnace includes a back wall, opposed side walls and top and bottom walls defining an interior space for one or more burner nozzles. A combustion air inlet opening is formed in the top wall and is covered by a generally rectangular inverted channel-shaped airflow guide and baffle member. A second generally rectangular box-shaped louvered airflow guide and baffle member is mounted on the interior side of the top wall over the combustion air inlet opening for distributing the flow of combustion air into the burner box assembly and to reduce acoustic emissions from the burner box assembly through the combustion air inlet opening. The combination of the louvered baffle member and the exterior mounted baffle member provides reduced acoustic emissions from the burner box assembly as well as more evenly distributed combustion airflow into and through the burner box assembly.
