Definitions

  • the present invention relates to an outdoor unit of a refrigeration cycle apparatus.
  • an outdoor unit of a refrigeration cycle apparatus such as an air-conditioning apparatus
  • a compressor, a heat exchanger, a fan, and other components are housed in a housing.
  • the outdoor unit of the air-conditioning apparatus is connected, through a refrigerant pipe, to an indoor unit housing a heat exchanger, a fan, and other components.
  • refrigerant circulates between the indoor unit and the outdoor unit through the refrigerant pipe.
  • the refrigerant pipe When such a refrigerant pipe is to be connected to the outdoor unit, the refrigerant pipe is attached to a connection port provided on an outer surface of the housing of the outdoor unit.
  • the position of the connection port is on a back panel side of the housing (see Patent Literature 1), for example.
  • Patent Literature 2 discloses an air-conditioner having a case comprising an interior that is divided into a heat exchange chamber and a machine chamber in an external unit, wherein the heat exchanger and an air blower are assembled in the heat exchange chamber and a liquid pipe service valve and a gas pipe service valve are supported on a support plate, wherein a projecting part comprises projections that are arranged around a fixed part of the support plate and wherein the support plate and a side plate are contact with each other by the projecting part.
  • Patent Literature 3 discloses an air conditioner outdoor device in which a liquid closing valve and a gas closing valve are arranged at an upper rear position, wherein, when this air conditioner outdoor device is installed at an outer wall just below a window, the two closing valves are positioned near the window, resulting in that either a connecting work of a pipe extending from the air conditioned room or an opening or closing work of the closing valve can be performed easily from within the room and wherein the device has the electrical element storing part arranged at a side part of a machine chamber and has a partition plate is installed between them, thereby making it possible to prevent water collected at the closing valves and near them to enter into the electrical element storing part.
  • An internal refrigerant circuit connecting the compressor, a four-way valve, the heat exchanger, and other components is complicatedly housed in the outdoor unit.
  • components such as the refrigerant pipe connected to the pipe connection port and a refrigerant pipe connected to the heat exchanger are in a complicated arrangement. With a poor assembly accuracy of each member, the refrigerant pipe and other components may contact peripheral members due to vibration of the compressor, generating operation noise.
  • the present invention has been made to solve such a problem, and is intended to provide an outdoor unit generating reduced operation noise by improvement of the assembly accuracy of each member around a pipe connection port of the outdoor unit.
  • the outdoor unit of an embodiment of the present invention comprises the features set out in claim 1.
