Abstract: A gas furnace according to an embodiment of the present disclosure includes: a mixer for mixing air and a fuel gas, which are introduced through an intake pipe and a manifold, respectively, to form a mixture; a mixing pipe through which the mixture, having passed through the mixer, flows; a burner assembly for producing a combustion gas by burning the mixture having passed through the mixing pipe; and heat exchangers through which the combustion gas flows, wherein the burner assembly includes: a plurality of burners, to which a flame produced during combustion of the mixture is anchored; a mixing chamber serving as a medium for delivering the mixture from the mixing pipe to the burners. Accordingly, a full premixing mechanism may be provided, and a mixing rate of the fuel gas and the air may be maximized, thereby greatly reducing nitrogen oxide emissions. Further, the burner assembly includes a uniform guide disposed inside the mixing chamber and allowing the mixture to be uniformly distributed to each of the plurality of burners, thereby preventing an increase in local flame temperature, and greatly reducing nitrogen oxide emissions.

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.

Abstract: An air conditioner is provided. The air conditioner includes a heat exchange module, at least one humidity sensor, and a controller. The heat exchange module includes a compressor, a first heat exchanger, an expansion valve, a second heat exchanger, and an absorbent disposed on an outer surface of the first and second heat exchangers. The controller is configured to control to stop a normal operation and perform a drying operation for supplying air to any one of the first and second heat exchangers serving as an evaporator when it is determined that a predetermined drying operation condition is satisfied based on humidity information of air passed through the any one of the first and second heat exchangers serving as the evaporator, during the normal operation in which the any one of the first and second heat exchangers serves as an evaporator and the other serves as a condenser.
