摘要： A method monitors an air-conditioner having a semi-conductor gas sensor, the method including: determining that a refrigerant leakage has occurred on condition that the detection value is equal to or greater than a first threshold when the fan is in operation; starting operation of the fan as a provisional operation if the detection value is equal to or greater than a second threshold when the fan is not in operation; stopping the provisional operation of the fan; determining that a refrigerant leakage has occurred on condition that the detection value is equal to or greater than a third threshold after stopping the provisional operation of the fan; and taking a predetermined action for outputting alarm information and/or limiting supply of refrigerant to the heat exchanger when a refrigerant leakage is determined to have occurred.

摘要： A thermal flow velocity and flow rate sensor includes: a substrate; a heater mounted on the substrate; a temperature measuring element mounted on the substrate; a joint portion made of a resin filled between the heater and the temperature measuring element and thermally connecting the heater and the temperature measuring element; a lead wire connected to the substrate; and a fastener fixing the lead wire to the substrate. The lead wire is soldered to the substrate. The lead wire and the fastener are coated with the resin.

摘要： An air conditioner includes a power source that supplies AC voltage and a wiring plug-in coupler connected to the power source. The wiring plug-in coupler is connected to a portion of the power source to which a first functional component, which is actuated by the AC voltage in cooperation with the air conditioner, is connected, supplies voltage to a second functional component actuated by DC voltage in cooperation with the air conditioner, and is connected with an input terminal of a converter that converts AC voltage to DC voltage and supplies the converted DC voltage to the second functional component.

摘要： A remote control device configured communicate with an air conditioner or a heat pump includes a touch panel having an electrode unit, a liquid crystal display, and a casing accommodating the touch panel and the liquid crystal display. The casing has a back surface part and a front surface part. The liquid crystal display is disposed to overlap the touch panel as seen from a front surface part side. The electrode unit has a first electrode section to detect a touched position, and a second electrode section that may function as an antenna to perform wireless communication with another communication device. The first and second electrode sections are configured and arranged to be nearer to the front surface part than to the back surface part inside the casing, and to be disposed so as not to overlap with each other as seen from the front surface part side.

摘要： A connection structure between a printed circuit board and a terminal block includes: an insertion portion at one end of the printed circuit board with a pattern disposed thereon; a terminal-block main body including a receiving port that receives the insertion portion; a nut held in the terminal-block main body; and a screw tightened into the nut. The pattern is interposed between the screw and the nut when the insertion portion is inserted into the receiving port.
