Definitions

  • the present invention relates to an air conditioner including a floor-standing indoor unit and a refrigerant sensor that detects a leakage of a refrigerant leaked from the floor-standing indoor unit.
  • Fluorocarbon refrigerants have stable physical properties and are easy to handle, but have a high global warming potential and an adverse effect on the global environment. For this reason, hydrocarbon refrigerants such as propane or propylene which are natural refrigerants with a low global warming potential are attracting attention as a substitute for the fluorocarbon refrigerants. However, the hydrocarbon refrigerants are flammable so that, when applied to an air conditioner, the refrigerant leaking from the air conditioner can reach a flammable concentration. It is thus desired that the air conditioner detects the leakage of the refrigerant at an early stage and take some measures to prevent the leaked refrigerant from reaching the flammable concentration.
  • a floor-standing indoor unit disclosed in Patent Literature 1 includes: a control board that integrally controls devices such as a blower fan, a fan motor, and a compressor; and a remote controller on which a user performs driving operation of an air conditioner, monitors an operating state as well as details of a problem of the air conditioner.
  • a refrigerant sensor is connected to the control board via wiring including a signal line.
  • the refrigerant sensor is installed at the bottom of the machine room in the floor-standing indoor unit disclosed in Patent Literature 1.
  • the refrigerant sensor is installed at the bottom of the machine room to be able to effectively measure the concentration of the leaking refrigerant because the specific gravity of the hydrocarbon refrigerant is higher than the specific gravity of the air.
  • the refrigerant sensor detects the refrigerant leaked from components of a refrigeration cycle such as a heat exchanger and a union joint, and when the concentration of the refrigerant reaches a predetermined value or higher, the floor-standing indoor unit operates the blower fan to diffuse the refrigerant and thus prevent an increase in the concentration of the refrigerant up to the flammable concentration.
  • the floor-standing indoor unit disclosed in Patent Literature 1 has a function of displaying the details of a problem on the remote controller in order to notify the user of the details of various problems occurring in the air conditioner.
  • the details of problems include refrigerant leakage information indicating leakage of the refrigerant, communication problem information indicating the occurrence of a problem in communication between the indoor unit and an outdoor unit, and disconnection problem information indicating the occurrence of disconnection of the signal line transmitting a refrigerant detection signal output from the refrigerant sensor.
  • JP2012 193884 A provides a refrigerant leakage detector capable of confirming a normal operation of the refrigerant leakage detector easily in the possible range on the inspection at any time besides regular checking or in such a case that there is no person in charge on the spot.
  • the refrigerant leakage detector which outputs an alarm display or/and an alarm sound on detection of the refrigerant leakage and, at the same time, outputs an alarm signal by means of an external output means (relay or the like).

  • the conventional floor-standing indoor unit typified by the one disclosed in Patent Literature 1 is configured to display the refrigerant leakage information that is given higher priority than the information such as the communication problem and the disconnection problem on the remote controller. This is to notify the user of the refrigerant leakage before the concentration of the refrigerant increases up to the flammable concentration and thus urge the user to ventilate the room in which the air conditioner is installed or operate the air conditioner by a user's operation and forcibly diffuse the refrigerant. Accordingly, when the signal line is disconnected after the refrigerant leakage is detected; the remote controller does not display the disconnection problem but displays only the refrigerant leakage information. A service technician therefore takes measures against only the refrigerant leakage of the floor-standing indoor unit displaying only the refrigerant leakage information, thereby realizing the disconnection problem after the measures are completed and needing to take measures against the disconnection problem anew.
  • the present invention has been made in view of the above, and an object of the present invention is to provide an air conditioner that can improve workability of measures against a disconnection problem without impairing measures against leakage of a flammable refrigerant.

  • the illumination controller 10a provided on the relay board 10 turns off the LED 302 when the wiring 16 being the signal transmission path between the control board 9 and the relay board 10 is disconnected, or turns on the LED 302 when the wiring 7a being the signal transmission path between the relay board 10 and the refrigerant sensor 7 is disconnected.
  • the service technician can roughly grasp the site of disconnection and save time associated with taking measures against the disconnection problem.
  • the air conditioner 100 includes the illumination controller 10a that turns on or off the luminous unit in the first illuminated state indicating that the signal transmission path of the refrigerant sensor 7 is disconnected, and blinks the luminous unit in the second illuminated state indicating that the signal transmission path of the refrigerant sensor 7 is not disconnected, whereby the service technician can easily know whether or not the signal transmission path of the refrigerant sensor 7 is disconnected.
  • the present embodiment has described the configuration example in which the connector is connected to the connection terminal to establish the electrical connection between the control board 9 and the relay board 10 and between the relay board 10 and the refrigerant sensor 7.
  • the wirings 7a, 16, and 22b may be directly connected to the connection terminals without using the connector, or may be soldered to wiring patterns (not illustrated) on the control board 9 and the relay board 10.
  • the present embodiment has described the example in which the LED 302 is provided on the control board 9 or the relay board 10, the LED 302 may be installed at any site outside the electrical component box 8 illustrated in FIG. 1 .
  • wiring (not illustrated) for connecting the LED 302 to the illumination controller 10a can be shortened or omitted as compared with the case where the LED 302 is installed at any site outside the electrical component box 8, so that the configuration of the control board 9 or the relay board 10 is simplified and that the yield as well as reliability are improved.
  • the LED 302 is provided outside the electrical component box 8 the visibility of the LED 302 is improved as compared with the case where the LED is installed on the control board 9 or the relay board 10, whereby the workability is improved in taking measures against the disconnection problem.
