摘要:
The current-sensing circuit 1 includes a shunt resistor R1 connected in series with a path of current from an inverter 106, an operational amplifier 12 amplifying voltage across both ends of this shunt resistor R1 with a predetermined gain, a low-pass filter 18 averaging output voltage of this operational amplifier 12, and an arithmetic unit 50 calculating the current flowing through the path based on output voltage of the low-pass filter 18. The supply voltage of the operational amplifier 12 is set higher than the supply voltage of the arithmetic unit 50. The output voltage of the operational amplifier 12 is averaged at the low-pass filter 18 to a lower value than the supply voltage of the arithmetic unit 50.

A remote controller in an air conditioning system includes a storage unit, a monitoring unit, and a data output unit. The monitoring unit acquires operation data from at least one of an outdoor unit or an indoor unit, and stores the acquired operation data in the storage unit. The monitoring unit stores operation data in the storage unit by overwriting the operation data stored in the storage unit when the storage unit stores the operation data in excess of a predetermined capacity. The monitoring unit saves the operation data stored in the storage unit during a past predetermined period when an abnormal condition occurs at the air conditioner during operation. The data output unit displays the saved operation data or sends the saved operation data externally.

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).

A remote control device (30) for switching the operating state of an air conditioning system (100) includes a touch screen (60) and physical keys (50). The touch screen (60) displays first through eighth icons (IC1-IC8) that function as touch keys. Each of the first through eighth icon (IC1-IC8) is displayed by words, graphics, or symbols associated separately with each of a plurality of set items. The physical keys (50) are provided separately from the touch screen (60). The physical keys (50) include two or more function keys (52), the number of which is fewer than the number of the icons (IC1-IC8). Each of the function keys (52) is assigned a common function utilized when the operating state is switched.
摘要:
An air conditioning system is provided in which a command is easily input to a plurality of remote control devices. An air conditioning system (100) includes: a plurality of indoor units (20) installed in a target space (SP); a plurality of remote controllers (30) arranged to respectively correspond to the indoor units (20); and a controller (50). A command is input to the remote controller (30), for setting of the corresponding indoor unit (20) or of the remote controller (30) itself. The controller (50) performs a process based on the command input to the remote controller (30). Each of the remote controllers (30) includes: a remote controller communicating unit (353) for performing a communication with a corresponding indoor unit (20); and a short range wireless communicating unit (34) for performing the short range wireless communication with a terminal (110) having a function of a short range wireless communication. A command can be input to each of the remote controllers (30) when the short range wireless communicating unit (34) acquires a signal transmitted from the terminal (110) by the short range wireless communication.
摘要:
To provide an air conditioner with excellent security. An indoor unit (20) has its operating state switched on the basis of a command sent from a terminal (90) that a user has and performs air conditioning of a utilization space (SP), the indoor unit (20) including: a storage component (61) that stores connection information in which identification information is included; a notification component (68) that gives notification of the connection information to the terminal (90); an adapter (37) that receives the command sent from the terminal (90) to which notification of the connection information was given; and an indoor unit control component (21) that executes switching control that switches action of an actuator on the basis of the received command. The connection information includes valid period information that designates a valid period in which it is possible for the operating state to be switched by the terminal (90) to which notification was given. The indoor unit control component (21) does not execute the switching control in response to a command sent from a terminal (90) for which the valid period designated in the valid period information of which notification was given has expired.
摘要:
A remote control (30) which is installed on a sidewall (SW) and carries out wired communication with an indoor unit (20) has a touch panel (70) including an electrode unit (71), a liquid crystal display (60) disposed so as to overlap the touch panel (70) as seen from a front surface part (32) side, and a casing (31). The casing (31) has a back surface part (33) that faces the sidewall (SW) in an installed state and the front surface part (32) that faces the indoor space (SI) in the installed state. The electrode unit (71) has a touch electrode section (72) that functions as an electrode for detecting a touched position, and an antenna electrode section (73) that functions as an antenna for performing wireless communication with an external communication device (110). The touch electrode section (72) and the antenna electrode section (73) are nearer to the front surface part (32) than to the back surface part (33) inside the casing (31) and are disposed so as not to overlap with each other as seen from the front surface part (32) side.
