Abstract: Provided is a gas furnace. The gas furnace includes: a manifold with an exhaust port for discharging fuel gas; a nozzle attached to the exhaust port; a burner for burning a mixture of air and fuel gas ejected from the nozzle; a primary heat exchanger that provides a first flow path and allows a combustion gas produced by the combustion of the mixture to move through the first flow path; and a secondary heat exchanger located adjacent to the primary heat exchanger, that provides a second flow path and allows the combustion gas discharged from the primary heat exchanger to move through the second flow path, wherein the secondary heat exchanger includes: at least one tube forming the second flow path; and a baffle inserted into the at least one tube, the baffle including: a plate longitudinally extending in a lengthwise direction and twisted in the shape of a screw; and a plurality of holes formed to penetrate the plate.

Abstract: A gas furnace includes: a burner in which a mixture of air and fuel gas burns; a heat exchanger through which a combustion gas produced by the combustion of the mixture flows; a duct including a room air duct through which air coming from a room passes and a supply air duct through which air supplied to the room passes; a blower that induces a flow of the room air supplied as the supply air to the room through the heat exchanger; and a humidification and dehumidification device with no water supply installed on one side of the supply air duct. The amount of moisture contained in the supply air is adjusted by an adsorbent coated on the surface of the humidification and dehumidification device with no water supply.
