    Abstract: A method of controlling a ceiling type air conditioner including a panel located on a ceiling surface, outlets formed at positions corresponding to four sides of the panel, a first vane group for opening and closing the outlets located at two opposing sides, and a second vane group for opening and closing the outlets located at the other two opposing sides includes performing a dynamic airflow mode in which an indoor temperature reaches a set temperature by controlling rotation angles of the first vane group and the second vane group, and calculating a pleasant airflow index Y for determining a pleasant feeling of a user at the set temperature. The pleasant airflow index is calculated using the indoor temperature, the rotation angle of the first vane group or the second vane group, an air volume, a distance from a floor surface and an airflow position as variables.

    Abstract: A network system and a method for controlling the same are provided. In the method, a power consumption amount of an electrical appliance is monitored (S22) based on an operation of the electrical appliance. If a demand response (DR) signal for requesting power saving is received (S23), it is determined (S24) whether a user is to participate in a DR event for a power-saving operation of the electrical appliance. If it is determined that the user is to participate in the DR event (S25), the power-saving operation of the electrical appliance is performed (S27) based on previously mapped information on a discomfort caused by the power-saving operation of the electrical appliance.

    Abstract: A gas furnace includes: a combustion part in which a fuel gas is burnt to generate a combustion gas; a heat exchanger having a gas flow path through which the combustion gas flows; a blower configured to blow air around the heat exchanger; and an inducer configured to discharge the combustion gas from the heat exchanger, wherein the heat exchanger includes: at least one single path in which a single gas flow path is formed; a single-multiple return bend configured to communicate with the single path and convert a flow direction of the combustion gas; and at least one multiple path having a plurality of paths that communicate with the single-multiple return bend and form multiple gas flow paths.

    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 NO x emissions.
