  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the directions such as up and down and left and right described below indicate directions when the outdoor unit 10 is installed and viewed from the front side.

  Drawing 1 is a figure showing the installation state of air harmony device 1 concerning the embodiment to which the present invention is applied. As shown in FIG. 1, the air conditioner 1 is suspended and installed on an indoor unit 3 that is suspended from a ceiling 2A of a conditioned room 2 and a ceiling surface (eave) 4 of a veranda or balcony on an upper floor. The outdoor unit 10 is provided. The indoor unit 3 and the outdoor unit 10 are connected by an inter-unit pipe (refrigerant pipe) 7 through an outer wall 5 that partitions the conditioned room 2 and the outside, and are preferably installed so that the back faces face each other. As a result, the efficiency of pipe connection work between the indoor unit 3 and the outdoor unit 10 can be improved and the length of the inter-unit pipe 7 can be shortened.

The air conditioner 1 is attached to, for example, a school or a hospital, and the outdoor unit 10 includes a unit case 11 that is suspended from the upper floor veranda or the ceiling surface 4 of the balcony. Since the outdoor unit 10 is provided suspended from the ceiling, an evacuation passage can be secured on a veranda or balcony used as an outdoor passage. Further, a hanging wall (smoke prevention wall) 6 protruding downward from the ceiling surface 4 by a predetermined amount or more is provided on the ceiling surface 4 of the veranda or balcony.
The unit case 11 of the outdoor unit 10 is provided with a front panel (front surface) 16 facing the hanging wall 6 obliquely downward toward the rear of the unit case 11, and an air outlet described later is provided on the front panel 16. 26 is provided.
In the present embodiment, the upper end portion 41 of the air outlet 26 is provided above the lower end 43 of the drooping wall 6, and the lower end portion 42 of the air outlet 26 is provided below the lower end 43 of the drooping wall 6. .

FIG. 2 is a side sectional view of the outdoor unit 10. As shown in FIG. 2, the unit case 11 includes a drain pan 13 that forms the entire bottom of the unit case 11, a top panel 12 that is formed longer than the length of the drain pan 13 in the front-rear direction, and a front end portion of the drain pan 13. And a front panel 16 provided toward the front end of the top panel 12. The dimension in the depth direction of the unit case 11 is formed larger than the dimension in the height direction. The drain pan 13 is formed in a tray shape, and includes a bottom portion 113 and a corner portion 114 formed by raising a peripheral edge portion of the bottom portion 113.
In the present embodiment, the front panel 16 is provided so that the inclination angle θ1 with respect to the drain pan 13 is approximately 50 degrees downward, and an air outlet 26 is formed on the front panel 16. A blower 22 is provided adjacent to the air outlet 26 at a position facing the air outlet 26. Further, the outlet 26 is provided with an outlet grill 26 a and a bell mouth 22 c around the blower 22. The blower 22 is composed of a propeller fan 22a and a fan motor 22b. When the propeller fan 22a is rotationally driven by the fan motor 22b, as indicated by an arrow X in the figure, the air from the rotation axis direction of the fan motor 22b Inhale and blow out air in the axial direction.
The front end portion of the top panel 12 is bent so as to intersect the upper end portion of the front panel disposed obliquely downward substantially perpendicularly to form a front upper portion 12a. Since the front upper portion 12a intersects the upper end portion of the front panel 16 substantially perpendicularly, it is possible to prevent air from being accumulated at the joint between the top panel 12 and the front panel 16, and the air in the unit case 11 can be prevented. Can be efficiently discharged by the blower 22.

  An outdoor heat exchanger 21 is provided behind the blower 22, and in the present embodiment, the outdoor heat exchanger 21 is provided substantially parallel to the front panel of the unit case 11 in which the air outlet 26 is formed. . A fixing bracket 28 for fixing the outdoor heat exchanger 21 to the unit case 11 is attached to the upper end portion of the outdoor heat exchanger 21. The lower end portion of the outdoor heat exchanger 21 is provided in contact with the rear corner portion 13 b of the drain pan 13. By arranging the outdoor heat exchanger 21 at an angle, the size of the unit case 11 in the height direction can be suppressed, and the space in the unit case 11 can be effectively used to exchange heat in the outdoor heat exchanger 21. The area can be expanded.

In addition, the outdoor heat exchanger 21 is arranged so that the projected area in the vertical direction of the outdoor heat exchanger 21 is within the drain pan 13. As a result, the water that has condensed on the surface of the outdoor heat exchanger 21 disposed obliquely and has fallen vertically downward due to gravity can be reliably collected by the drain pan 13.
Further, when the outdoor heat exchanger 21 is exposed to dew or the like and the air path between the fins is blocked, the air conditioning efficiency decreases. In this embodiment, the outdoor heat exchanger 21 is Since it is arranged obliquely, the moisture attached to the surface of the outdoor heat exchanger 21 falls efficiently on the drain pan 13 by gravity. Therefore, it is possible to prevent a decrease in air conditioning efficiency. Further, since the outdoor heat exchanger 21 is arranged obliquely, even when the defrosting operation of the outdoor unit 10 is performed in winter, the frost attached to the outdoor heat exchanger 21 is efficiently drained vertically downward by gravity. Therefore, the defrosting operation efficiency of the outdoor unit 10 can be improved. The blower 22 is provided at a position where it does not overlap with the outdoor heat exchanger 21 so that dew water falling from the outdoor heat exchanger 21 is not applied.
According to this configuration, water droplets from the outdoor heat exchanger 21 can be received by the drain pan 13, so that the drain water does not droop from the outdoor unit 10. Therefore, even if the outdoor unit 10 is suspended from the ceiling, the drain water can be prevented from dripping down onto the veranda or the balcony.

  When the propeller fan 22a is rotationally driven by the fan motor 22b, as indicated by an arrow X in the figure, outside air is sucked from the back side of the unit case 11, and exchanges heat with the refrigerant flowing in the outdoor heat exchanger 21. Then, the air is discharged from the outlet 26 to the outside of the unit case 11 by the blower 22. The air after heat exchange discharged from the air outlet 26 flows along the axial direction of the blower 22 and is discharged substantially perpendicularly to the front panel 16 provided obliquely downward. In the present embodiment, since the front panel 16 is disposed downward by about 50 degrees, the air blown from the blower outlet 26 is blown downward by an inclination angle θ2 with respect to the horizontal direction of about 40 degrees. Therefore, as shown in FIG. 1, even when the drooping wall 6 is present at the eaves edge, the air blown from the outlet 26 is discharged outside without being blocked by the dripping wall 6. As a result, the occurrence of a short circuit phenomenon due to the hanging wall 6 can be prevented, and a reduction in air conditioning efficiency can be prevented.

  In the unit case 11 having a certain height dimension, the inclination angle θ1 can increase the heat exchange area of the outdoor heat exchanger 21 as the inclination is slow, but the dimension in the depth direction of the unit case 11 is large. In addition, the blowing capacity of the blower 22 is also reduced. The inclination angle θ1 can reduce the depth dimension of the unit case 11 as much as the inclination is increased, but the heat exchange area of the outdoor heat exchanger 21 is reduced. For this reason, it has been determined from a verification experiment or the like that the optimum inclination angle θ1 is about 50 degrees downward.

  FIG. 3 is a front view of the outdoor unit 10 with the top panel 12 of the unit case 11 removed. As shown in FIG. 3, the unit case 11 is formed in a horizontally long flat box shape, and two air outlets 26, 26 are formed on the front panel 16 side by side. The air outlets 26 and 26 are formed over substantially the entire area of the front panel 16 in the vertical direction.

The partition plate 18 is fixed to the front panel 16 and the bottom plate 13 with screws or the like, and is formed so as to contact the top panel 12. According to this configuration, since the inside of the unit case 11 is divided into the machine room 101 and the heat exchange room 102 by the partition plate 18, the air passing through the outdoor heat exchanger 21 does not flow to the machine room 101 side. The air after heat exchange can be efficiently discharged out of the unit case 11 from the heat exchange chamber 102 via the blower 22.
The machine room (one side) 101 is provided with refrigerant circuit components such as a compressor 23, an accumulator 24, and a four-way valve. The heat exchange chamber (the other side) 102 is provided with blowers 22, 22 provided on the front side of the unit case 11 and an outdoor heat exchanger 21 provided behind the blowers 22, 22. Although not shown, the outdoor heat exchanger 21 is a fin-and-tube heat exchanger in which thin plate-like fins that are heat transfer plates are arranged around a tube through which a refrigerant flows.

The drain pan 13 is provided by being screwed to the side panels 14 and 15 with screws or the like. The compressor 23 and the accumulator 24 are provided upright on the drain pan 13 and are disposed on the rear side of the machine room 101.
According to this structure, since the compressor 23 is arrange | positioned on the drain pan 13, since the frost which arrived at the compressor 23 falls on the drain pan 13, it can be discharged | emitted as drain liquid. Furthermore, since the refrigerant circuit components such as the compressor 23 are arranged close to the back side of the unit case 11, it is easy to pull out the pipe from the back side of the unit case 11, and the connection workability with the inter-unit pipe 7 can be improved. it can. Furthermore, since a mesh-like rear fingered 19 that covers the back surface of the unit case 11 is provided on the back surface of the machine room 101, the ventilation in the machine room 101 is good, and the heat in the machine room 101 is efficiently obtained.

Can be received and dispersed by the entire plate member 27b. Further, since the plate member 27b is provided with a plurality of holes 27a to reduce the weight, the stress applied to the fixing portions of the side panel 14 and the partition plate 18 to which the motor base 27 is fixed can be reduced. Further, according to this configuration, for example, the blowers 22 and 22 are fixed to the bracket 27c in advance, the plate member 27b is fixed to the inside of the unit case 11, and the bracket 27c is fixed to the plate member 27b. Since the blowers 22 and 22 can be easily disposed obliquely downward and fixed inside the fan, the workability of mounting the blower 22 can be improved.
Further, in the present embodiment, the motor base 27 is substantially parallel to the propeller fan 22a in the heat exchange chamber as compared with a general front-blowing outdoor unit arranged with the motor base standing substantially vertically on the bottom plate or the like. 102, the motor base does not enter the rotation range of the propeller fan 22a of the blower 22 and the propeller fan 22a and the motor base 27 interfere even if the blower 22 is disposed obliquely downward. There is nothing.

The outdoor heat exchanger 121 fixes the upper end of the heat exchanging part 21A to the upper back of the unit case 11, fixes the lower end of the outdoor heat exchanging part 21B to the lower part of the rear of the unit case, and connects the heat exchanging parts 21A and 21B. It is fixed inside the unit case 11 while being bent at the connecting portion. As a result, the outdoor heat exchanger 121 has a substantially square cross-sectional shape viewed from its side surface, and can increase the heat exchange area.

  As described above, according to the present embodiment, the outdoor heat exchanger is arranged on the rear side of the heat exchange chamber side by side with the compressor provided in the machine room, so that a sufficient heat exchange area is secured. Thus, the height of the unit case 11 of the outdoor unit 10 can be reduced, and the overhead space can be prevented from being narrowed even when the unit case 11 is suspended from the ceiling 4 of the veranda or balcony. be able to. Furthermore, by arranging the outdoor heat exchanger at an angle, moisture such as dew on the surface efficiently falls due to gravity and does not block the air path between the fins, thus preventing a decrease in air conditioning efficiency. Can do. Further, even when the defrosting operation of the outdoor unit 10 is performed in winter, the frost attached to the outdoor heat exchanger 21 can be efficiently removed by gravity, so that the defrosting operation efficiency of the outdoor unit 10 is improved. Can do.

  Moreover, according to this embodiment, since the whole bottom part of the unit case 11 is formed with the donpan larger than the projection area of the outdoor heat exchanger 21 in the vertical direction, it is condensed on the surface of the outdoor heat exchanger 21. The water dropped by gravity can be reliably collected by the drain pan 13. Further, moisture such as frost attached to the compressor 23 can also be collected by the drain pan 13. Therefore, the drain water does not drop from the outdoor unit 10, and even when the outdoor unit 10 is suspended from the ceiling, the drain water can be prevented from dripping onto the veranda or the balcony.

  Further, a general outdoor heat exchanger is provided upright on the bottom plate of the unit case. However, in the present embodiment, the outdoor heat exchanger 21 is disposed obliquely inside the unit case. With the heat exchanger 21 attached, the work space from the top panel 12 side is reduced. Therefore, the upper end portion of the outdoor heat exchanger 21 is sandwiched between the fixing brackets 28, and the fixing brackets 28 are fixed to the side panel 14 and the partition plate 18. As a result, the outdoor heat exchanger 21 is detachable from the top panel side, and when the outdoor unit 10 is assembled, for example, the outdoor heat exchanger is attached lastly to secure a work space in the unit case 11. This can improve the assembly work efficiency.

Thereby, the mounting workability of the outdoor heat exchanger 21 can be improved.

  Moreover, since the electrical equipment box 25 was attached to the partition plate 18 and the heat radiating plate 28 of the electrical equipment box 25 was disposed on the heat exchange chamber side, the air current in the heat exchange chamber 102 was used to be stored in the electrical equipment box 25. Heat dissipation from electrical components such as a power transistor that drives the compressor 23 can be efficiently discharged.

  Further, the outdoor heat exchanger 21 is formed by connecting two heat exchanging portions 21A and 21B and bending them at the connecting portion to form a substantially cross-sectional shape, and is disposed inside the unit case. When the outdoor unit 10 is installed in a place where the installation space is limited, a sufficient heat exchange area can be secured even if the dimension in the depth direction is kept small as well as the dimension in the height direction of the case 11. Furthermore, the unit case 11 can be made more compact.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to this. In the present embodiment, the compressor 23 is configured to stand on the drain pan 13, but is not limited thereto, and may be configured to include the compressor 23 in a lying state. Moreover, in this embodiment, although it was set as the structure which arrange | positions the air blower 22 diagonally downward, the air blower 22 is good also as a structure arrange | positioned so that air may be blown off in a horizontal direction.
