    摘要： Disclosed are a gas furnace and an air conditioner having the same. The gas furnace includes: a burner for burning fuel; a manifold providing the fuel to an entry of the burner; a heat exchanger spaced apart from an exit of the burner and providing a passage for combustion gas generated by the burner; an inducer for causing a fluid to flow through the burner and the heat exchanger; a blower for causing a flow of air passing around the heat exchanger; and an air shutter positioned between the manifold and the entry of the burner. The air shutter includes: a housing having an inner space that communicates with the manifold and the entry of the burner; and a primary hole formed to penetrate the housing and able to be opened and closed.

    摘要： Disclosed is a gas furnace including a mixer configured to mix air and fuel gas introduced from an intake pipe and a manifold respectively so as to produce an air-fuel mixture, a mixing pipe configured to allow the air-fuel mixture having passed through the mixer to flow therein, a burner assembly configured to combust the air-fuel mixture having passed through the mixing pipe so as to generate combustion gas, heat exchangers configured to allow the combustion gas to flow therein, an exhaust pipe configured to discharge exhaust gas, which is the combustion gas having passed through the heat exchangers, to the outside. The gas furnace further includes a recirculator installed around the exhaust pipe and configured to guide a portion of the exhaust gas flowing in the exhaust pipe to the mixer, and may thus greatly reduce or fundamentally block NOx emissions.

    摘要： Provided is a condensate water trap for a gas furnace that collects and discharges condensate water produced in a heat exchanger and an exhaust pipe. The condensate water trap includes: a first inlet through which the condensate water produced in the heat exchanger is introduced; a second inlet through which the condensate water produced in the exhaust pipe is introduced; a first flow path through which the condensate water coming from the first inlet passes; a second flow path through which the condensate water coming from the second inlet passes; an outlet through which the condensate water introduced through the first and second inlets is discharged; a third flow path into which the residual condensate water passed through at least one of the first and second flow paths but not discharged through the outlet is introduced; and a sensing mechanism that senses if the amount of residual condensate water introduced into the third flow path is greater than or equal to a given amount.

    摘要： A method of controlling a gas furnace comprising a gas valve for supplying a fuel gas to a manifold; a burner through which the fuel gas discharged from the manifold passes; an igniter for igniting a mixture of fuel gas passed through the burner and air; and an inducer for generating a flow in which a combustion gas generated by the burning of the mixture is discharged to an exhaust pipe via a heat exchanger, wherein the gas furnace performs a heating operation according to a heating signal or a heating stop according to a stop signal, includes the steps of: (a) receiving any one of the heating signal or the stop signal; (b) transmitting a signal to operate the inducer when the heating signal is received; (c) operating the igniter; (d) transmitting a signal to open the gas valve; (e) detecting whether the gas valve is opened or closed; (f) detecting a flow rate of the fuel gas in the manifold; and (g) displaying a normal operation of the heating operation, based on information detected in the steps (e) and (f).
