Description

[Detailed Description of the Invention] The present invention relates to an air supply/exhaust heat exchanger used to exhaust contaminated indoor air and simultaneously supply fresh outside air.

That is, in the present invention, a large number of thin metal plates and hygroscopic sheets are vertically stacked alternately at regular intervals in the casing body, and the thin metal plates and hygroscopic sheets are arranged in one section separated by the casing body. Attach front and rear blind plates to the front and rear of the
In addition, upper and lower blind plates are fixed to the top and bottom of the first section, which are displaced from the front and rear blind plates, and a large number of exhaust passages and air supply passages are formed alternately, thereby efficiently controlling temperature and humidity during exhaust and air supply. The object of the present invention is to provide an air supply/exhaust heat exchanger that can perform energy exchange and achieve desirable energy savings.

Next, embodiments of the present invention that can achieve the above objects will be described in detail with reference to the accompanying drawings.

Figures 1 to 7 show an embodiment of the present invention. Figure 1 is a side view, Figure 2 is a front view of the same as above, Figure 3 is a sectional view taken along the line - - of Figure 2, and Figure 4 is a cross-sectional view of Figure 3. 6 is an enlarged sectional view of the main part, and FIG. 7 is an enlarged front view of the thin metal plate, where a is the casing body consisting of the front and rear plates 1, left and right side plates 2, and upper and lower plates 3, and 4 is the casing body. A large number of thin metal plates, 9 indicates a large number of hygroscopic sheets, 5 indicates front and rear blind plates, 6 indicates upper and lower blind plates, and the thin metal plates 4 and the hygroscopic sheets 9 exist at a constant interval within the casing body a. That is, a plurality of protrusions 4a formed opposite to each other on the thin metal plate 4 are vertically stacked alternately with their tips abutting against the hygroscopic sheet 9. Then, front and rear blind plates 5 are fixed to the front and rear of the first section divided by the thin metal plate 4 and the hygroscopic sheet 9, and the upper and lower blind plates 6 are displaced from the front and rear blind plates 5 of the first section. The exhaust passages O and the air supply passages I are fixed to each other in the upper and lower portions, so that a large number of exhaust passages O and intake passages I are arranged alternately and intersecting each other. Note that 1a, 1a, and 3a indicate through holes bored in the front and rear plates 1 and the upper and lower plates 3 in the exhaust passage O and the air supply passage i. In addition, in Fig. 1, 7 is an exhaust duct, 8 is an air supply duct, arrow x is an exhaust direction,
The arrow y indicates the air supply direction, and the arrow in the exhaust passage O in FIG. 3 and the arrow in the air supply passage i in FIG. 4 indicate the direction of exhaust and air supply.

FIG. 5 is an explanatory diagram of one embodiment, where 7 is an exhaust duct, 8 is an air supply duct, and a is a casing body, that is, a heat exchanger according to the present invention, in which indoor contaminated air is passed through an exhaust passage O. The air is exhausted as shown by the arrow x, and at the same time, fresh outside air is supplied into the room as shown by the arrow y through an air supply passage i that intersects with the exhaust passage O. When the outside air flows through the air supply passage i and the exhaust gas flows through the exhaust passage O, the thin metal plate 4
The temperature and humidity are exchanged with the warm air in the exhaust passage O through the hygroscopic sheet 9.

FIG. 8 shows another embodiment, in which a separator 10 is inserted into the exhaust passage O and the air supply passage i, and the separator 10 is inserted through a shaft through a thin metal plate 4 and a hygroscopic sheet 9. 11, which is intended to strengthen the assembly.

As described above, the present invention includes a large number of thin metal plates and a hygroscopic sheet in the casing body, and a plurality of protrusions formed on the thin metal plate are brought into contact with the hygroscopic sheet and arranged vertically at regular intervals. The front and rear blind plates are fixed to the front and rear of the first section, which is divided by these thin metal plates and hygroscopic sheets, and the upper and lower blind plates are fixed to the top and bottom of the first section, which is displaced from the front and rear blind plates. By forming a large number of exhaust passages and air supply passages that alternately intersect with each other, the turbulent flow that hits the protrusions when exhausting contaminated indoor air and supplying fresh outside air,
This has the effect that temperature and humidity can be exchanged extremely efficiently through the thin metal plate and the hygroscopic sheet.
