摘要： An air conditioning system includes an outdoor unit and an indoor unit connected to the outdoor unit through an air conditioning communication line. The outdoor unit includes: a control unit; a compressor; a fan; a compressor inverter; a fan inverter; a heat exchanger; and valves of various types. The control unit of the outdoor unit has a coupling capacitor and a noise-cutting transformer which are between a communication circuit and the air conditioning communication line.

摘要： An air conditioner includes a plurality of indoor units of a refrigerant circuit to perform air conditioning of a space, and an air conditioning controller that controls operations of the plurality of indoor units by allocating the indoor units individually to a plurality of predetermined areas of the space. The controller performs an area registration process of allocating the indoor units individually to a plurality of area identification frames corresponding to the areas, and allocating a plurality of ventilators individually to the area identification frames where the indoor units are allocated. The ventilators perform ventilation of the space. The controller does not allow the operations of the plurality of the indoor units when there is an area identification frame to which none of the ventilators is allocated, in the plurality of area identification frames where the indoor units are allocated.

摘要： In a device network system, system recognition processing that identifies a device connected by a wired line is performed using a low-frequency signal of a frequency lower than a first frequency used in communication, and a signal of the first frequency is used to transmit predetermined instruction information. The low-frequency signal includes first information for connection to a network, and identification information of a group to which a device to which the low-frequency signal is transmitted belongs. The predetermined instruction information is transmitted to a device that has received the low-frequency signal, has registered the first information, and has connected to the network, and for which participation in the network has been approved.

摘要： Provided is technology to implement an updating process according to a situation of each equipment when software is collectively updated with respect to a plurality of equipment items constituting an equipment system. With respect to a software updating method for a plurality of equipment items constituting the equipment system, the software updating method includes acquiring information indicating an operation state of at least respective equipment to be updated among the plurality of equipment items, acquiring information indicating a reception state of updated software of the respective equipment, determining whether to perform switching to the updated software by the respective equipment, and instructing switching to the updated software based on a result of a determination. The determining determines that the switching to the updated software by the respective equipment is not to be performed in a case where equipment in operation and from which reception is incomplete exists.

摘要： An air conditioning system has an air conditioner, which includes an outdoor unit and an indoor unit that configure a refrigerant circuit, and a controller, which controls the running of the air conditioner. The controller does not allow operation of the air conditioner to start in a case where a signal from a ventilation unit that includes a ventilation fan for ventilation and ventilates a target space or a refrigerant leak sensor that detects refrigerant leakage in the target space is not input to the controller. Because of this, even in a configuration where an air conditioner and a ventilation unit are installed independently of each other, operation of the air conditioner can be performed in a state in which there is reliably established a countermeasure such as the ventilation unit being operated when the refrigerant has leaked, and safety and security with respect to refrigerant leakage are reliably ensured.
