Abstract: In a heat source-side unit according to the present invention, a temperature sensor is installed on an inter-column connecting part included in a plurality of inter-column connecting parts and located higher than an intermediate position in a vertical direction of a heat exchanger.

Abstract: An indoor unit of an air-conditioning apparatus includes a header main pipe to which an indoor pipe is connected at a brazed portion and header branch pipes. The header branch pipes are connected to first ends of heat-transfer pipes included in an indoor heat exchanger at brazed portions. The indoor pipe is connected to indoor refrigerant branch pipes at brazed portions. The indoor refrigerant branch pipes are connected to second ends of the heat-transfer pipes. A first leaked refrigerant receiver is disposed under the brazed portions. A first temperature sensor is disposed in the first leaked refrigerant receiver. A second leaked refrigerant receiver is disposed under flare joints connecting the indoor pipes to extension pipes, respectively. A second temperature sensor is disposed in the second leaked refrigerant receiver.

Abstract: An air-conditioning apparatus determines whether or not to permit an air-conditioning operation based on refrigerant amount information stored in an outdoor unit and installation height information stored in an indoor unit.

Abstract: An air-conditioning apparatus includes a refrigerant circuit in which a compressor, a flow switching device, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger are connected by pipes and through which refrigerant flows, and a control device controlling an operation of the refrigerant circuit to perform switching between a heating operation and a defrosting operation. The control device includes a determination unit that determines, based on operation information regarding the refrigerant circuit, during the heating operation, whether to change a requirement for starting the defrosting operation, a changing unit that changes the requirement for starting the defrosting operation in accordance with a result of determination by the determination unit, and a switching unit that, when the requirement for starting the defrosting operation is satisfied, causes the flow switching device to perform switching to start the defrosting operation.

Abstract: In a fastening device, to an impact wrench body 2 of an impact wrench 1 a jig holder 5 is detachably fitted. To this jig holder 5 a socket integrated type whirl-stop jig 6 is detachably fitted. The socket integrated type whirl-stop jig 6 is constituted by a whirl-stop jig body 7 which is detachably fitted to a jig holder 5, a socket 8 which is rotatably supported on the jig body 7, and a coupling member 13. The socket 8 and the coupling member 13 are connected to be relatively movable in an axial direction and rotatable in one-piece with each other. The coupling member 13 is connected with the rotary shaft 20 of the impact wrench 1, and a fastener 28 is engaged with the socket 8 to be tightened to the screw 37 of the rotary shaft 36 to which the clutch inner part 33 is fitted. The whirl-stop jig body 7 has a one-piece whirl-stop part 32, which is engaged with the rib 34 of the clutch inner part 33, to whirl-stop the clutch inner part 33.
