    Abstract: A ventilation apparatus includes a casing having the inside partitioned into a first floor and a second floor. A first sharing duct is formed in the first floor and configured to suck one of indoor air and outdoor air and to have the sucked air horizontally moved. A second sharing duct is formed in the second floor and configured to suck the other of indoor air and outdoor air and to have the sucked air horizontally moved. First and second heat exchangers are disposed in the first and second sharing ducts, respectively. The ventilation apparatus is advantageous in that air resistance is minimized, horizontally moving air is subject to heat exchange with the entire area of the heat exchanger, and efficiency of heat exchange between air and the heat exchanger is improved because air is divided into the first floor and the second floor and horizontally moved.

    Abstract translation: 通风装置包括具有分隔成第一层和第二层的内部的壳体。 第一共享管道形成在第一层中并且构造成吸入室内空气和室外空气中的一个并使吸入的空气水平地移动。 第二共享管道形成在第二层中并且构造成吸入室内空气和室外空气中的另一个并使吸入的空气水平地移动。 第一和第二热交换器分别设置在第一和第二共用管道中。 通风装置的优点在于，空气阻力最小化，水平移动的空气与热交换器的整个区域进行热交换，并且改善了空气和热交换器之间的热交换效率，因为空气被分为一层 二楼水平移动。

    Abstract: A heat supplier may include a compressor that compresses a refrigerant; a first heat exchanger that exchanges heat between air and the refrigerant; a second heat exchanger that exchanges heat between a fluid and the refrigerant; a switching valve that directs the refrigerant discharged from the compressor into the first heat exchanger or the second heat exchanger; a first liquid pipe that connects the first heat exchanger and the second heat exchanger; a second liquid pipe connected in parallel to the first liquid pipe so as to connect the first heat exchanger and the second heat exchanger; a first expansion valve disposed at the first liquid pipe and configured to expand refrigerant flowing therethrough; and a second expansion valve disposed at the second liquid pipe and configured to expand refrigerant flowing therethrough. A size of an aperture of the second expansion valve may be greater than a size of an aperture of the first expansion valve, enabling a flow rate of refrigerant to be adjusted according to an operation mode.

    Abstract: The present disclosure relates to a condensate trap for a gas furnace for collecting and discharging condensate generated in a heat exchanger and an exhaust pipe, the condensate trap including: a first inlet through which the condensate generated in the heat exchanger is introduced; a second inlet through which the condensate generated in the exhaust pipe is introduced; a first passage through which the condensate introduced from the first inlet passes; a second passage through which the condensate introduced from the second inlet passes; a discharge port through which the condensate, having passed through the first passage and the second passage, is discharged outside; and a backflow prevention device disposed on the first passage and configured to prevent backflow of air, wherein the backflow prevention device includes: a housing; and a core which is movably disposed in the housing, and which in response to an amount of the condensate introduced from the first inlet being less than or equal to a predetermined amount, prevents backflow of the air by closing the first passage.

    Abstract: Provided is a gas furnace including a primary heat exchanger and a secondary heat exchanger through which a combustion gas produced by the combustion of a fuel gas flows. The gas furnace includes: a coupling box serving as an intermediary to connect the primary heat exchanger and the secondary heat exchanger; a collect box connected to the secondary heat exchanger, for letting in the combustion gas passed through the secondary heat exchanger; an inducer connected to the collect box, for inducing a flow of the combustion gas; and a bypass pipe connected to one side of the coupling box and including a bypass pipe for guiding the combustion gas passed through the primary heat exchanger to a hot water supply tank for supplying hot water to an indoor space.

    Abstract: 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.
