The present invention relates to a ceiling-embedded heat exchanger installed in the ceiling of a building. In particular, the height of the heat exchanger is reduced by eliminating an auxiliary panel that makes the crossroads constant when indoor air is discharged through the heat exchanger. The present invention relates to a ceiling-embedded heat exchanger configured by connecting a coil located at the bottom of the heat exchanger with an inlet pipe so that water remaining in the heat exchanger can be completely discharged.

In general, the heat exchanger is used in various ways, and among them, the ceiling-embedded heat exchanger installed in the ceiling so as to be less restricted by space is configured as shown in FIG.

That is, the slab concrete is composed of a decorative panel 2, an air entry and exit panel 4, a filter 5, a blower 6, a heat exchanger 8, a drain 11 and an auxiliary panel 12. It is installed between (13) and the ceiling panel (17).

In more detail, a decorative panel 2 is installed to suck indoor air into the hole formed at the center of the lower bottom surface of the frame 1 and to discharge the air to the side hole formed at the side of the central hole, and the cover 3 is disposed thereon. An air inlet and outlet panel 4 is provided and is formed so that the air inlet 4-1 and the outlet 4-2 of the air are separated from each other at the center and both sides, respectively, and are formed at the center of the air inlet and outlet panel 2. The filter 5 is provided in (4-1).

In addition, the blower 6 is installed to guide the sucked air to the heat exchanger frame 7 while being positioned in the upper one side space of the frame 1, and several coils 9 inside the heat exchanger frame 7. The heat exchanger 8, which is assembled by a plurality of fins FIN 8-1 having several holes formed thereon so as to be fitted horizontally, is fixed by the fixing panel 10, It is inclined at an angle of about 40 degrees, and a drain 11 receiving water generated by the temperature difference in the heat exchanger 9 is installed in the lower portion.

Then, the cold hot water is supplied through an intake pipe (not shown in the drawing) using one coil located at the lower side of the several coils 9 mounted on the several fins 8-1 as the inlet coil 9-1. , The drain coil 9-2 for discharging the water circulated through each coil 9 through the drain pipe (not shown in the drawing) is a coil located at the upper portion.

The remaining coils other than the inlet coil 9-1 and the drain coil 9-2 are connected to each other in pairs from the outside of the heat exchanger 9 so that water can circulate.

The auxiliary panel 12, which allows air through the heat exchanger 8 to be discharged only to the outlet 4-2 of the air entry / exit panel 4, has a bottom surface of the drain 11 and an air entry / exit panel 4. It is fixed to the side of the frame (1) in the upper portion of the outlet (4-2).

The heat exchanger formed as described above is supported by the support means 15 connected to the strong anchor bolt 14 fixed to the slab ZHS concrete 13, and the vibration of the heat exchanger is applied to the intermediate portion of the support means 15 to the slab concrete ( 13 is provided with a dustproof window 16 for preventing the case of being transmitted to and broken.

Therefore, in use, when the blower fan of the blower 6 in the heat exchanger is rotated by the power of a motor, the heat exchanger heats the sucked indoor air in the heat exchanger 8 and is discharged through the discharge port 4-2.

In this case, the indoor air is sucked into the heat exchanger frame 7 by the rotation of the blower fan of the blower 6 through the inlet 4-1 of the air entry / exit panel 4 through the filter 5.

Therefore, the air introduced through the blower 6 is heat-exchanged by the water circulating in the coil 9 mounted on the heat exchanger 8 configured as described above, so that the air flows between the auxiliary panel 12 and the frame 1. Through the discharge port 4-2 is discharged.

At this time, the auxiliary panel 12 is located between the drain 11 and the discharge port 4-2 receiving the water generated by the temperature difference in the heat exchanger 8 to provide a flow path and backflow to the blower 6 Block it.

As a result, the overall height of the heat exchanger becomes high, which increases the volume and the manufacturing cost.

Therefore, the spacing between the slab concrete 13 and the ceiling panel 17 is not constant, and in some cases, the distance between the slab concrete 13 and the ceiling panel 17 is relatively small, so that the decorative panel 2 of the heat exchanger is much more exposed than the ceiling panel 17. In some cases, there are disadvantages such as the case where installation is impossible.

In addition, the inlet coil 9-1 of the heat exchanger 8 is located at the bottom of several coils 9 installed in the heat exchanger 8, wherein at least one coil is provided below the inlet coil 9-1. When the heat exchanger 8 is not used, water in the coil located below the inlet coil 9-1 is not discharged when the water is discharged through the inlet pipe. Chi can cause freezing concerns.

Freezing is serious and, for example, if it is installed in a hotel, it may damage all the interior of the hotel, cause a short circuit, and affect the image of the hotel's celestial bodies.

In addition, when repairing the heat exchanger, it is necessary to remove the decorative plate and remove the main body to repair the product.

In view of the above, the present invention eliminates the auxiliary air panel in the air circulation direction, that is, the cross-section, to discharge the air passing through the heat exchanger to the outside, thereby increasing the horizontal and inclined degree of the heat exchanger. The height is reduced, and the inlet pipe is connected to the coil located at the bottom of the heat exchanger to prevent freezing of the winter heat exchanger, so that the repair plate does not have to be removed.

That is, in a heat exchanger that is supported by a support means connected to the strong anchor bolt between slab concrete and the ceiling panel, the indoor air sucked by the blower to the center of the bottom of the cremation panel and the air access panel is inclined horizontally and about 40 degrees. In a heat exchanger in which the air circulation direction is made constant by the sub-panels of the channel formed between the drain and the air entry / exit panel by heat exchange, the heat exchanger is inclined 50 to 60 degrees horizontally so that the bottom of the heat exchanger Close to the outlet of the air inlet and outlet panels, and the drain edge of the bottom of the heat exchanger directly contacts the outlet edge instead of the subpanel so that it can slide directly. Several coils mounted on the heat exchanger are connected to the inlet and drain pipe connections Of coils installed in the heat exchanger The inlet coil and the inlet pipe connector located on the side are on the same horizontal line, and one side of the decorative panel extends the auxiliary panel portion, and the opening and closing of a service door which is open and closed on the auxiliary panel portion reduces the height of the heat exchanger and prevents freezing It is.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings, and the conventional structure will be described with the same reference numerals.

If water is discharged when not in use, make sure to drain it completely.

In addition, the upper edge portion of the frame 1 is used as the curved surface 20 so that the air flows smoothly, which is shortened due to the elimination of the auxiliary panel 12 so that the curved surface 20 forms a turbulent flow. To reduce the occurrence and to facilitate the discharge.

In addition, the present invention, one side of the decorative panel (2) is formed to extend the auxiliary panel portion (2-1) and the auxiliary panel portion (2-1) to the opening and closing the service door (2-2).
