Definitions

  • the present disclosure provides an indoor unit capable of placing a refrigerant sensor in a limited space of a housing.
  • the indoor unit 100 is a duct type indoor unit installed in a ceiling space, in a wall, under a floor, or the like.
  • the indoor unit 100 is formed in a changeable manner of a placing direction of an air outlet 108 out of which air to be conditioned is blown so that a blowing direction can be changed depending on an installing location. For this reason, for example, when horizontally blowing, as shown in Fig. 1 , the indoor unit 100 is installed in a so-called horizontal suspending state where the air outlet 108 is located on the side. Further, when blowing upward, the indoor unit 100 is installed in a so-called vertical suspending state where a blower port is located above.
  • an up-down direction means an up-down direction when the indoor unit 100 is installed in the horizontal suspending state.
  • the configuration of the blower chamber 105 in the present embodiment is one example, and the number of the blowers 110 and the number of the fan motors 111 are not limited to the above configuration.
  • a drain pan 121 is provided in an entire location of the bottom panel 101f that faces the heat exchanger chamber 107.
  • the drain pan 121 is a flat plate-shaped member that functions as a water receiving unit to receive drain water generated in the heat exchanger chamber 107.
  • the drain pan 121 is formed of, for example, Styrofoam or the like.
  • the drain pan 121 and a location of the bottom panel 101f in which the drain pan 121 is provided are both provided removably from the housing 101.
  • the heat exchanger 120 is placed in a longitudinal direction extending along the left-right direction of the heat exchanger chamber 107.
  • the heat exchanger 120 placed in this way has an upper edge supported on the heat insulating material provided in the front wall 101a and the top panel 101e, and the heat exchanger 120 has a lower edge supported on a location of the drain pan 121 that is located on a partition plate 103 side. For this reason, the heat exchanger 120 is placed in a tilted state from a front wall 101a side toward the partition plate 103 side as being from the upper edge toward the lower edge.
  • the bent portion 131b at a front end of the board support plate 131 includes a first opening 131c
  • the inner bent portion 154a of the side plate 151 includes a second opening 154c.
  • the first opening 131c and the second opening 154c overlap with each other and form an opening A.
  • the opening A communicates between the inside of the electrical box 130 and the heat exchanger chamber 107.
  • a wiring 135 connected to the board 133 is inserted into the opening A and thereby drawn into the heat exchanger chamber 107.
  • the board for the electrostatic atomization device is a board for controlling the electrostatic atomization device.
  • the electrostatic atomization device is connected to the wiring 135 and connected to the board 133 via the wiring 135.
  • the indoor unit 100 is formed so that the refrigerant sensor 180 can be accessed from three directions relative to the refrigerant sensor 180 on the front wall 101a side, a bottom panel 101f side and the left wall 101c side.
  • One end portion 212 of the piping member 210 is placed in the placement space S1.
  • the refrigerant sensor 180 detects the refrigerant, so that the leakage of the refrigerant occurring not only in the refrigerant piping connecting portion 150 but also in the vent portion 140 can be detected. Specifically, in the indoor unit 200, even when the leakage of the refrigerant occurs in each of the vent portion 140 and the refrigerant piping connecting portion 150 provided on opposite sides of the heat exchanger 120, the leakage of the refrigerant can be detected.
  • the heat exchanger chamber 107 is provided on the front wall 101a side, and the air outlet 108 is provided in the front wall 101a.
  • the blower chamber 105 may be provided on the front wall 101a side
  • the heat exchanger chamber 107 may be provided on the back wall 101b side.
  • the refrigerant sensor 180 is provided on the back wall 101b.
