摘要： The degree of freedom when a refrigerant cycle system is constructed in a building or the like is increased. A refrigerant cycle system according to the present disclosure includes a refrigerant cycle, a first power feed unit, a second power feed unit, a first transmission line, and a second transmission line. The power feed unit feeds auxiliary power to a utilization unit of which a power source has been interrupted. The first transmission line connects a heat source unit and the first power feed unit to each other. The second transmission line connects the first power feed unit and the second power feed unit to each other. The second power feed unit is connected to the heat source unit via the first power feed unit.

摘要： A power measurement apparatus includes a voltage detector, current detector, and power calculator. The voltage detector contactlessly detects an AC voltage of a conductive path to which power is supplied from an AC power source having a magnitude of AC voltage regulated to be a predetermined value, and outputs a first data signal regarding a voltage waveform of the AC voltage of the conductive path. The current detector contactlessly detects an AC current flowing through the conductive path, and outputs a second data signal regarding a current waveform of the AC current of the conductive path. A power calculator receives the first and second data signals, and calculates active power of the conductive path from a product of a second instantaneous voltage and an instantaneous current of the current waveform indicated by the second data signal. The second instantaneous voltage is generated by converting a first instantaneous voltage.

摘要： System recognition is performed on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, an outdoor unit selected from among all outdoor units of a first network performs a recognition process on the outdoor units and indoor units of the first network. In the first network, communication between individual devices including the outdoor units and the indoor units is performed by using a high frequency, and the recognition process performed by the selected outdoor unit uses a recognition signal having a low frequency.

摘要： A device-registration-work assisting system includes a plurality of notification units, and a mobile terminal carriable by a worker. Each notification unit is built in or disposed near one of a plurality of devices subjected to registration work. The mobile terminal includes a display unit configured to display information regarding each of the devices, and a selection unit configured to select a corresponding one of the devices. The notification unit is configured to notify the worker by light, sound, or motion in response to the corresponding device being selected with the selection unit.

摘要： System recognition is performed on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, in a state in which a first device group is set in advance as a physically connectable system or in a state in which the first device group is recognized as a physically connectable system, in a case where the first device group or a second device detects occurrence of a state in which the second device outside the system is recognized as belonging to the system, the first device group or the second device causes the second device to leave the system. As a result, a network can be normally maintained even in high-frequency communication.

摘要： In a network in which devices are classified into a plurality of layers, a physical first line is connected to an outdoor unit and a first indoor unit, which are first-layer devices, and a physical second line is connected to a second indoor unit, which is a second-layer device. A first intermediary unit, which is a first intermediary device, includes a first filter always connected to the first line and the second line. The first intermediary unit communicates with the outdoor unit and the second indoor unit via a first signal. The first filter is installed so as not to attenuate a high-frequency first signal used for communication among the outdoor unit, the first indoor unit, the first intermediary unit, and the second indoor unit and so as to attenuate a low-frequency second signal used for communication between the first intermediary unit and the second indoor unit.

摘要： A refrigerant jacket includes a refrigerant cooling member, a cover member and a strength member. The cooling member is constructed of aluminum or aluminum alloy that thermally contacts a heat emitting electrical part, and has a groove portion. A refrigerant tube of a refrigerant circuit fits into the groove portion. The cover member covers the refrigerant cooling member in a state where the refrigerant tube has been fitted into the groove portion. The strength member is higher in strength than the cooling member, and is fixed to the cooling member. The cover member has a cover-side through hole opposing the strength member. The strength member has a cover member fixing screw hole opposing the cover-side through hole. The cover member is fixed to the strength member by a cover member fixing screw that passes through the cover-side through hole and screws into threads of the cover member fixing screw hole.
