    Abstract: Disclosed are a gas furnace and an air conditioner having the same. The gas furnace includes: a burner for burning fuel; a heat exchanger extending long and providing a passage for combustion gas generated by the burner; a blower for causing a flow of air passing around the heat exchanger; and a plurality of guides passing through the heat exchanger and spaced apart from each other in a longitudinal direction of the heat exchanger. The heat exchanger includes: a first tube forming an entry of the heat exchanger; a second tube forming an exit of the heat exchanger and spaced apart from the first tube in a direction crossing the longitudinal direction of the heat exchanger; and a bend connecting the first tube and the second tube. The plurality of guides is alternately disposed in a direction in which the first tube and the second tube are spaced apart from each other.

    Abstract: An engine system of the present disclosure includes an engine configured to drive a plurality of pistons by burning a mixture of air and gas, an air supply pipe through which the air supplied to the engine flows, a supercharger configured to compress the air flowing through the air supply pipe, a gas supply pipe through which the gas supplied to the engine flows, and a mixer configured to mix the air that has passed through the supercharger and the gas. The mixer has a venturi tube shape in which a cross-sectional area of a flow path decreases and expands in a flow direction of the air that has passed through the supercharger, and the gas supply pipe is connected to a portion of the mixer where the cross-sectional area of the flow path in the mixer is decreased.
