Definitions

  • the present disclosure relates to an air conditioner.
  • Mount plate 18 is mounted on rear surface 10a of indoor unit 10 at the time of factory shipment, that is, for transportation.
  • Mount plate 18 has a large number of fastening holes 18a and claws 18b.
  • Fastening holes 18a are holes penetrating through mount plate 18.
  • mount plate 18 is fastened to a wall surface or the like of the room, with screws or the like, not illustrated, through fastening holes 18a.
  • Each of claws 18b has a shape protruding forwards, and hooks onto the top and bottom edges of housing 14 and hold indoor unit 10.
  • mount plate 18 is fastened onto rear surface 10a of indoor unit 10, with claws 18b being hooked onto the top and bottom edges of housing 14.
  • Different pipe opening 14a may be used to pass indoor-side connection pipe 12, depending on a positional relationship between hole H formed in the wall surface and the position where indoor unit 10 is installed.
  • indoor-side connection pipe 12 is pulled out of indoor unit 10 through pipe opening 14a on the left side.
  • the length of indoor-side connection pipe 12 is equal to or longer than twice the longitudinal width of rear surface 10a, indoor-side connection pipe 12 can be pulled out of indoor unit 10, by passing indoor-outdoor connection pipe 20 through any one of pipe openings 14a. Therefore, when indoor unit 10 is installed, the position where indoor-side connection pipe 12 and outdoor-side connection pipe 32 are connected is located outside of the indoor unit 10.
  • the length of indoor-side connection pipe 12 is equal to or longer than twice the longitudinal width of rear surface 10a, and is pulled out of indoor unit 10 through pipe opening 14a. Therefore, the connection between indoor-side connection pipe 12 and outdoor-side connection pipe 32, the connection being where the refrigerant leakage occurs, is located outside of indoor unit 10. Therefore, even when the refrigerant leaks at the position of the connection between indoor-side connection pipe 12 and outdoor-side connection pipe 32, the leaked refrigerant does not accumulate inside indoor unit 10. As a result, it is less likely for the refrigerant to catch the fire ignited by the motor of indoor fan 13, electric components 16, or the like, as an ignition source, advantageously.
  • the length of indoor-side connection pipe 12 is equal to or longer than twice longitudinal length W1 of rear surface 10a of indoor unit 10.
  • Indoor unit 10 includes mount plate 18 that is mounted removably on indoor unit 10, and mount plate 18 holds indoor-side connection pipe 12 on mounting surface 18c that is on the opposite side of a surface facing indoor unit 10 during transportation of the indoor unit.
  • the first exemplary embodiment has been described above as an example of the technology disclosed in the present application.
  • the technology in the present disclosure is not limited thereto, and may be applied to exemplary embodiments with some changes, replacements, additions, omissions, or the like applied thereto. Therefore, other exemplary embodiments will be explained below.
  • indoor-side connection pipe 12 the length of which is longer can be disposed on the inner side of rear surface 10a along the outer periphery of rear surface 10a. Therefore, it is possible to achieve both improvement in safety of air conditioner 1 and improvement in transportability of air conditioner 1.
  • the present disclosure can be applied to air conditioners.
  • the present invention can be applied to home-use and business-use air conditioners that use a flammable refrigerant.
