Abstract: A refrigerant management system includes at least one computer including an acquisition unit and a generation unit. The acquisition unit, during installation and/or maintenance of a refrigerant use device, acquires first information, refrigerant already filled quantity, and refrigerant used quantity. The first information includes device specifying information, worker information, and refrigerant additionally filled quantity information. The refrigerant already filled quantity is preliminarily filled in the refrigerant use device, in accordance with the device specifying information. The refrigerant used quantity used in the refrigerant use device by totaling the refrigerant already filled quantity acquired and the refrigerant additionally filled quantity included in the refrigerant additionally filled quantity information.

Abstract: An air conditioning system includes a plurality of air conditioning indoor units installed in a target space, a plurality of remote control devices corresponding to the air conditioning indoor units, and a controller. The remote control device has a command input to set the corresponding air conditioning indoor unit or the remote control device. The controller performs a process based on the command input to the remote control device. Each remote control device includes a communicating unit that performs a communication with the corresponding air conditioning indoor unit, and a short range wireless communicating unit that performs a short range wireless communication with a communicating apparatus having a function of the short range wireless communication. The command is input by receiving a signal transmitted from the communicating apparatus by the short range wireless communication, at the short range wireless communicating unit.

Abstract: A remote control device includes a display unit, physical keys, and a control unit to control operations of the display unit and execute various processes in accordance with commands input via the physical keys. The display unit includes a setting item display area to display setting item information pertaining to configurable setting items, and a set state display area to display information pertaining to set state of the setting items. The physical keys include at least one function key and a separate set state change key. The control unit successively selects the setting items, causes the display unit to display the setting item information, and performs an increase or decrease of a numerical value, a stage change, or a mode change relating to the setting item. The number of function keys is smaller than the number of the setting item information displayed.

Abstract: An air conditioner is installed in a target space. An operating state is switched based on a command sent from a portable communication terminal. The air conditioner includes a specific information storage component, a specific information notification component that gives notification of the specific information to the communication terminal, a command receiving component that receives the command sent from the communication terminal, and an actuator drive component that executes a switching control that switches action of an actuator based on the command received. The specific information includes identification information and operable period information that designates an operable period during which the operating state is switchable by the communication terminal.

Abstract: A remote control for an air conditioner facilitates setting of various kinds of data without operation of a button. A remote control (30) includes an external communication unit (45) having an NFC circuit (42) and an NFC antenna (43). The external communication unit (45) is capable of wirelessly communicating with an external apparatus even when a microcomputer (36) in the remote control (30) is not supplied with power (i.e., in a non-operating state). Hence, through the wireless communication between the external communication unit (45) of the remote control (30) and the external apparatus, the various kinds of data is forwarded from the external device to the remote control (30), and stored in the remote control (30).

Abstract: 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.
