Definitions

  • the present invention relates to an outdoor unit for a split type air conditioner.
  • FIG. 3 shows an example of a conventional split type air conditioner.
  • An outdoor unit 1 is installed outside a room, and an indoor unit 2 is installed in the room. Then, with a service panel 7 being removed, a liquid refrigerant pipe 3a and gas refrigerant pipe 3b, which run from the indoor unit 2, are connected to operation valves 4a and 4b, respectively, and a control signal line 5 is connected to a terminal 6, by which the outdoor unit and indoor unit are connected to each other.
  • the present invention was made to solve the above problem, and an object thereof is to provide an outdoor unit for a split type air conditioner, in which an operation valve bracket is provided and operation valves to each of which a refrigerant pipe running from an indoor unit is connected are installed on this operation valve bracket, characterized in that a recess for providing a clearance between the operation valve bracket and an operation nut for the operation valve is formed in the operation valve bracket.
  • the outdoor unit for a split type air conditioner is also characterized in that the recess is formed so as to have dimensions such that at least a closed wrench can be inserted.
  • FIG. 1(A) is a front view of an operation valve bracket
  • FIG. 1(B) is a sectional view taken along the line B-B of FIG. 1(A).
  • An operation valve bracket 9 is formed with recesses 20 for providing a clearance between the operation valve bracket 9 and an operation nut 4c at portions corresponding to the operation nut 4c for each liquid-side operation valve 4a and gas-side operation valve 4b.
  • this recess 20 have dimensions such that at least a closed wrench can be inserted.
  • an operation nut 4c can be turned by inserting a closed wrench, monkey wrench, spanner, or the like in the recess 20.
  • the recess for providing a clearance between the operation valve bracket and the operation nut for operation valve is formed in the operation valve bracket, in the case where the refrigerant pipe running from the indoor unit is connected to or disconnected from the operation valve, when a monkey wrench or spanner is used, the turning angle thereof can be made large, so that the operation nut can be turned easily and rapidly.
  • the operation nut can be turned by using a closed wrench.
