The diffuser 51 is provided at one side of the casing 53 having a tubular shape with open ends, a pair of blocking portions 59 for blocking openings at both ends of the casing 53, and one side of the blocking portion 59. The pipe connecting portion 63 is connected to the casing 53, and includes a plurality of air passing holes 55 through which air passes. The diffuser 51 further includes an opening and closing control unit 65 coupled to the inner surface of the casing 53 to slidably open and close the air passing hole 55 formed in the casing 53.

The casing 53 has a rectangular cylindrical shape, and the three surfaces of the casing 53 have a plurality of air passing holes 55 formed in a row in the horizontal direction with respect to the longitudinal direction of the casing 53. Each air passage group is formed at equal intervals along the longitudinal direction of the casing 53. And, the casing 53 is formed with a receiving groove 57 for accommodating the handle 69 of the opening and closing adjustment unit 65 to be described later and limiting the moving distance of the handle 69. Here, the casing 53 may have a polygonal or circular cross-sectional shape, such as a triangle or a pentagon, instead of a rectangular cross-sectional shape. In addition, the air passage hole 55 may be formed only on one side or two side surfaces of the casing 53.

Each of the blocking portions 59 is provided with a plurality of support protrusions 61 protruding from the plate surface to support and slide the one side plate surface of the opening / closing control portion 65. In addition, the one side blocking portion 59 is provided with a pipe connection portion 63 through which the pipes are connected to penetrate the plate surface so that air can flow into and out of the casing 53.

The opening and closing adjustment part 65 has a plate shape as shown in FIG. 7, and has a length relatively shorter than the side length of the casing 53 so as to be slidable along the longitudinal direction of the inner surface of the casing 53. In addition, the opening / closing adjustment part 65 is formed with a plurality of air adjusting holes 67 communicating with the air passing holes 55 of the casing 53. Three opening and closing control unit 65 is provided so as to correspond to each of the three inner surface of the casing 53 in which the air passage hole 55 is formed. Opening and closing control unit 65 is a plurality of air control holes 67 formed in a row in the horizontal direction in the longitudinal direction of the plate corresponding to the air through hole group forms a single air control hole group, each air control hole group is predetermined It is formed to increase from one end of the plate surface to the other end along the longitudinal direction of the plate surface at intervals of. And the opening-closing adjustment part 65 is provided with the some handle 69 which protrudes from the board surface and is accommodated in the accommodation groove 57 of the casing 53. As shown in FIG.

Thus, looking at the assembly process of the diffuser 51 is as follows.

Next, the blocking portion 59 of the casing 53 is closed so that the openings at both ends of the casing 53 are blocked, and the support protrusion 61 of the blocking portion 59 is brought into close contact with the other side surface of each opening / closing control portion 65. By providing the opening at both ends, the assembly of the diffuser 51 is completed.

And, the flow control operation process of the diffuser 51 is as follows.

8A illustrates a state in which the air passage hole 55 of the casing 53 and the air control hole 67 of the opening / closing control unit 65 are not in communication with each other. That is, since the air control hole 67 of the opening and closing control unit 65 is staggered with the air passage hole 55 of the casing 53, the air passage hole 55 of the casing 53 is closed and the casing 53 is closed. Through the air passage hole 55 of the air is not introduced or discharged into or out of the casing (53). As shown in FIG. 8B, the diffuser 51 of the air passage hole 55 is closed, and the handle 69 of the opening / closing control part 65 opens the receiving groove 57 of the casing 53. By moving along the left side, the air passage hole 55 of the casing 53 and the air control hole 67 of the opening / closing control unit 65 communicate with each other, and the air passage hole 55 of the casing 53 is opened. Then, the opening and closing control part 65 along the receiving groove 57 of the casing 53 so that the air passage hole 55 of the casing 53 and the air control hole 67 of the opening and closing control part 65 communicate in part. By changing the position of the handle 69 of the, it is possible to adjust the amount of air flowing into or out of the casing 53 through the air passage hole 55 of the casing 53. In addition, by installing so that the number of the air control hole 67 of the opening and closing adjustment unit 65 is closer to the pipe connection portion 63, the air flowing into or out of the casing 53 along the longitudinal direction of the casing 53 By compensating for the pressure loss, the amount of air flowing into or out of the casing 53 along the longitudinal direction of the casing 53 is approximately equal.

By such a configuration, when the air supply fan 13 is operated, the air introduced from the outside by the air supply fan 13 and supplied to the room is discharged to the outside while passing through the heat exchanger 11 and the double pipe 27. Heat-exchanged and supplied to the room by the air supply diffuser 41 provided in the lower area of the room, and at the same time, when the exhaust fan 15 is operated, the indoor air discharged to the outside by the exhaust fan 15 is provided in the upper area of the room. It passes through the double pipe 27 and the heat exchanger 11 via the exhaust diffuser 47, and exchanges heat with the outdoor air supplied to the room and is discharged to the outside. At this time, since the air is supplied from the lower region of the room and exhausted from the upper region of the room, air circulation in the room is smooth. Then, by opening and closing each air passing hole 55 of the air supply diffuser 41 and the exhaust diffuser 47 with the opening and closing control unit 65, it is possible to adjust the air supply amount and the exhaust amount. In addition, since the air supply diffuser 41 and the exhaust diffuser 47 are provided on the lower wall surface of the room and the upper wall surface of the room, it is not necessary to extend the height between the floors.

On the other hand, Figure 9 is a schematic indoor installation layout of the air supply diffuser and the exhaust diffuser as another embodiment according to the present invention. As shown, it is shown that the air supply diffuser 41 and the exhaust diffuser 47 can be installed along the wall of each area without being locally installed in the lower area and the upper area of the room, respectively.

In this way, the air supply pipe and the exhaust pipe are installed to pass through the indoor floor, and the air is supplied from the lower part of the room and exhausted from the upper part of the room, thereby recovering waste heat, smoothing the air circulation in the room, and reducing the height between each floor of the building. The construction cost can be reduced.

In the above-described embodiment, it has been described as connecting the air supply pipe and the exhaust pipe to each of the heat exchanger tee and the indoor tee by one double pipe and to one air diffuser and one exhaust diffuser provided indoors. Of course, the heat exchanger tee and the indoor tee and the double pipe connecting the two, the air supply diffuser and the exhaust diffuser may be provided with a plurality of air supply and discharge.

As described above, according to the present invention, the air supply pipe and the exhaust pipe are installed to pass through the indoor floor, and the air is supplied from the lower area of the room and exhausted from the upper area of the room, thereby recovering waste heat, smoothing the air circulation in the building, and The building's supply / exhaust system is provided to reduce the height of each floor and reduce the construction cost.
