DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting short tube movably mounted on a lower opening of a ceiling mounted total heat exchanger having an outside air treatment function.

[0002]

2. Description of the Related Art FIG. 1 is a view showing an embodiment of the present invention. Of these, known parts will be described for better understanding of the present invention.

In FIG. 1, a total heat exchanger body 1 provided with an outside air processing unit 20 is mounted above an opening b of a ceiling plate a by a suspension bolt 26, and a short mounting pipe 10 is fixed by a stop. The grill 15 is attached to the total heat exchanger main body 1 by screws 15, and the grill main body 4 a is further attached to the mounting branch pipe 10. The grill plate 4 is attached to the grill main body 4a with a gap. Inside the body 1
A total heat exchanger element 2 having a square side surface is mounted with its corners up, down, left and right, and a partition plate 3 is attached to a lower corner in contact with a grill plate 4. A partition wall 5 that is inclined upward toward the unit 20 is attached to the corner, and the air supply inlet chamber A, the air supply outlet upstream chamber B1, the air supply outlet downstream chamber B2, and the exhaust air inlet chamber are formed by these members 1 to 5. C and an exhaust outlet chamber D are defined. In the main body 1, an upstream opening 6a of the air supply outlet upstream chamber B1 and a downstream opening 6b of the air supply outlet downstream chamber B2 are formed.

On the other hand, the outside air processing unit 20 includes a partition 2
1 and, for example, the humidifying element 22, an inlet chamber 23 communicating with the upstream opening 6a and an L-shaped outlet chamber 24 communicating with the downstream opening 6b are defined.

The air supply E passes through the element 2 from the air supply inlet chamber A and is sent from the air supply outlet upstream chamber B1 to the inlet chamber 23 through the upstream opening 6a. Then, the air is humidified when passing through the humidifying element 12, and the humidified air supply E1 is discharged from the outlet chamber 24 through the downstream opening 6b to the indoor G through the air supply outlet downstream chamber B2. On the other hand, the air in the indoor G, that is, the exhaust F, passes through the element 2 from the exhaust inlet chamber C and is discharged outside from the exhaust outlet chamber D. At this time, both the exhaust gas F and the supply air E pass through the element 2, so that heat is exchanged with each other and heat is recovered. That is, for example, when ventilation of the heated indoor G is performed, the heat energy of the exhaust F is recovered to the air supply E.

[0006]

In the above-described ceiling-mounted total heat exchanger having the outside air treatment function, the ceiling plate a
Depending on the position, that is, when it is high, in order to fit the exchanger body 1 inside the ceiling plate a, the mounting short pipe 10 is raised upward by a height H as shown by a chain line and mounted on the ceiling plate a. There is a need.

However, when the mounting short pipe 10 is raised upward, for example, by a height H as shown in the figure, the downstream opening 6b is raised to the height H.
Closed, the area of the outlet passage of the outside air processing unit 20 is reduced, and the outside air processing function is impaired. In order to avoid this, if the total heat exchanger main body 1 and the mounting branch pipe 10 are configured to have a margin, the overall height becomes large and it becomes impossible to enter the ceiling.

The present invention provides a ceiling-mounted type with an outside air treatment function that can secure an exit passage area for an outside air treatment function while maintaining a dimension that fits into a narrow ceiling regardless of the attachment position of the attachment branch pipe. It is intended to provide a short pipe for mounting the total heat exchanger.

[0009]

According to the present invention, a short pipe movably attached to a lower opening of a ceiling-mounted total heat exchanger having an outside air treatment function is provided on a side of an outlet passage side of the outside air treatment function. An easy-to-cut member is provided in the portion.

It is preferable that the easy-to-cut member is made of a plate or cloth that is easy to cut, and is attached or stuck to a notch formed in the short attachment tube with a band plate.

[0011]

In the ceiling-mounted total heat exchanger having the outside air treatment function configured as described above, when the mounting short pipe is raised upward when the heat exchanger is mounted on the ceiling, a portion for reducing the passage area is reduced. The easy-to-cut member is cut with scissors or a knife, and bent, for example, to the outside air treatment function side, and the bent portion is fixed, for example, with a clip to secure a passage area.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, on the side of the outside air unit 20 of the mounting short pipe 10, a width W2 slightly larger than the width W1 of the lower opening 6b and a height H1 is, for example, about twice as large as the height H. A notch 11 is formed. A plate 12 (a rubber plate with a thin cloth), which is a member that is easy to cut, is attached to the notch 11 by band plates 13 on both sides.

Next, the operation will be described.

If it is necessary to mount the exchanger main body 1 on the exchanger main body 1 with the mounting short pipe 10 raised by the height H, the notch 11 of the portion J of the plate body 12 indicated by oblique lines is required. 3 is cut by scissors or a knife along a portion along both edges thereof, and as shown in FIG.
To the bottom plate 25 side. And the bent edge 12a
Is clamped by the band 14 on the rising portion 25a of the bottom plate 25 and fixed. As a result, the outlet passage area of the outside air processing unit 20, that is, the opening area of the downstream opening 6b is secured.

[0016]

According to the present invention, as described above, the passage area of the outside air processing unit can be secured irrespective of the mounting position of the mounting branch pipe of the exchanger, and the mounting workability is improved. can do.
