JP 9-126494 A

However, hot air that is guided by the guide plate and flows upward is positive pressure, but the air near the air inlet is negative pressure because air is sucked in, and the hot air is low pressure. Therefore, there is a problem that hot air is sucked from the air suction port and a short cycle occurs.
In addition, when it is placed on the roof of a building, the hot blown air that flows upward is also blocked by the building wind and turned downward, and flows near the air inlet of the outdoor unit for the adjacent air conditioner Therefore, there is a problem that hot air is sucked from the air suction port and a short cycle occurs.

  An object of the present invention is to provide an outdoor unit for an air conditioner in which a large number of units are installed in one place and hot air discharged from an air discharge port is prevented from being sucked from the air intake port to prevent a short cycle. Is to provide.

  In the outdoor unit for an air conditioner according to the present invention, in the outdoor unit for an air conditioner in which the air suction port is provided below the air discharge port, air does not flow between the upper end of the air suction port and the air discharge port. A horizontal partition for partitioning is arranged.

  The effect of the outdoor unit for an air conditioner according to the present invention is that hot air discharged from the air discharge port is blocked by the horizontal partition in the middle even if hot air flows toward the air suction port having a negative pressure. It is to prevent a short cycle caused by being sucked from the mouth.

FIG. 1 is a perspective view of a horizontal partition plate in the best mode for carrying out the present invention.
The horizontal partition 1 includes a partition plate 2 that is supported at the four corners and can be expanded and contracted by changing the positions of the supported four corners, and support columns 3 a to 3 d that support the four corners of the partition plate 2.
The partition plate 2 includes two fixed beams 5a that connect both ends of two telescopic beams 4a and 4b in which a wire material having a spring property is processed into a wave shape, and two telescopic beams 4a and 4b arranged in parallel. 5b. Then, the two telescopic beams 4a and 4b and the two fixed beams 5a and 5b are connected to form a substantially rectangular frame.
Moreover, the partition plate 2 is provided with the expansion-contraction sheet | seat 6 by which four sides are fixed to the expansion-contraction beams 4a and 4b and the fixed beams 5a and 5b which are each edge | side of a frame.

Since the stretchable sheet 6 is not breathable between the front and back sides, the air flowing toward the stretchable sheet 6 flows along the surface of the stretchable sheet 6. Further, when the telescopic sheet 6 expands and contracts the telescopic beams 4a and 4b, the area covered by the telescopic sheet 6 in a direction perpendicular to the surface increases or decreases.
The support columns 3 a to 3 d include a horizontal leg 11 that contacts the floor surface when the horizontal partition 1 is arranged, a vertical leg 12 that stands vertically on the horizontal leg 11, and an oblique 13 that reinforces the vertical leg 12.
The vertical leg 12 includes a fixed portion 14 that is vertically fixed with one end fixed to the horizontal leg 11, a movable portion 15 that moves up and down along the fixed portion 14, and a fixing member 16 that fixes the raised and lowered movable portion 15 to the position at that time. Prepare.

FIG. 2 is a diagram illustrating a state in which the horizontal partition 1 is arranged between two outdoor units 21 for an air conditioner.
Next, a state in which the horizontal partition 1 is arranged between the two air conditioner outdoor units 21 will be described.
The two outdoor units 21 for air conditioners that are arranged with the horizontal partition 1 in between are arranged a predetermined distance apart so that sufficient air is supplied to the air suction port 22. Further, the outdoor unit 21 for the air conditioner increases the temperature of the air sucked from the air suction port 22 by taking heat from the refrigerant flowing into the heat exchanger by a heat exchanger (not shown), and the raised air is a fan (not shown) Is discharged upward from the air outlet 23.

  When the horizontal partition 1 is disposed in the air conditioner outdoor unit 21 that is separated by a predetermined distance, the support pillars 3 a to 3 d are arranged so that the four horizontal legs 11 are close to the casing 24 of the air conditioner outdoor unit 21. Arrange them so that they are at the four corners of the rectangle. Next, in order to prevent air from flowing between the air suction port 22 and the air discharge port 23, the partition plate 2 is disposed at a position above the upper end of the air suction port 22 and below the air discharge port 23. . At that time, the fixing member 16 is once loosened, the movable portion 15 is moved up and down, and the partition plate 2 is moved up and down in the vertical direction, and the fixing member 16 is tightened when it reaches an appropriate position.

When the horizontal partition 1 is disposed between the two air conditioner outdoor units 21 as described above, the hot air flowing upward from the air discharge port 23 is caused to flow downward by the wind flowing above the air conditioner outdoor unit 21. Even if it goes down toward the partition plate 2, the flow direction is changed by the partition plate 2 to become a horizontal flow. Therefore, hot air does not flow into the space surrounded by the casing 24, the partition plate 2, and the floor of the two air conditioner outdoor units 21.
And since hot air is not mixed into the air flowing through the space surrounded by the casing 24, the partition plate 2 and the floor of the two air conditioner outdoor units 21, the temperature of the air sucked into the air suction port 22 is high. Therefore, short cycle can be prevented.

FIG. 3 is a diagram showing a state in which 18 horizontal partitions 1 are arranged in 24 outdoor units for air conditioners arranged in 6 rows and 4 columns.
The outdoor unit for an air conditioner has a heat exchange capacity and power amount of 1 when the suction temperature is 35 ° C. for comparison, and the heat exchange capacity decreases to 0.9 when the suction temperature is 43 ° C. The amount increases to 1.1. And when the temperature of the outdoor unit for the air conditioner is 43 ° C. due to reflection from the floor, etc., operating without the horizontal partition 1 causes a short cycle and the suction temperature rises to 48-49 ° C. The high-pressure cut is generated by the outdoor unit for an air conditioner whose capacity is greatly reduced.
On the other hand, when the horizontal partition 1 is arranged and operated in an outdoor unit for an air conditioner under the same conditions as described above, the suction temperature is approximately 40 ° C. or lower when the temperature is approximately, and the short cycle is greatly improved.

  In the outdoor unit for an air conditioner according to the present invention, even when hot air discharged from the air discharge port 23 flows toward the air suction port 22 having a low pressure, the hot air is blocked by the horizontal partition 1 on the way. A short cycle caused by suction from the suction port 22 is prevented.

Further, even if the separation distance between the adjacent air conditioner outdoor units is different, by changing the width of the partition plate 2, the space between the casing 24 of the air conditioner outdoor unit and the side end of the partition plate 2 is changed. Since the gap does not become large, even if the separation distance of the outdoor unit for the air conditioner is different, it can be partitioned by one type of horizontal partition 1.
In addition, since the lengths of the support pillars 3a to 3d can be changed, a desired position can be partitioned by one type of horizontal partition 1 even with respect to an outdoor unit for an air conditioner in which the position of the air suction port provided is different. it can.

It is a perspective view of the horizontal partition plate in the best form for implementing this invention. It is a figure which shows a mode that a horizontal partition is arrange | positioned between the two outdoor units for air conditioners. It is a figure which shows a mode that 18 horizontal partitions were arrange | positioned at the 24 outdoor units for air conditioners arrange | positioned at 6 rows 4 columns.
