Abstract

PURPOSE:To form the title device into a thin shape and improve the ventilation efficiency thereof by arranging a plurality heat exchangers whose ridgelines in the longitudinal direction are opposed to each other, in parallel in the width direction, causing the external air outlet side and the exhaust air inlet side of each heat exchanger to oppose to a ceiling surface panel, and providing external air blow-off ports on both side portions of the ceiling surface panel and an exhaust air suction port at the central portion thereof. CONSTITUTION:External air A is sucked up through a suction flange 14 by the rotation of a blower 2 and enters a suction chamber 9 from an external air chamber 1a. External air A is removed of dusts and dirts by means of filters 5A and 5B, and enters blow-off chambers 10A and 10B via heat exchangers 4A and 4B. Then, external air A is blown off into the chamber through blow-off ports 7a and 7b of a ceiling surface panel 7A. Exhaust air B is sucked up from the central suction port 7b at the center of the ceiling surface panel 7A into a suction chamber 11 by the rotation of a blower 3. Exhaust air B is removed of dusts and dirts, and enters blow-off chambers 12A and 12B via heat exchangers 4A and 4B. Then, exhaust air B passes through communication chambers 13A and 13B, and is discharged out of the chamber from a flange 15 via an exhaust air chamber 1b. Thus, since heat exchangers 4A and 4B are arranged in parallel in the width direction, the unit can be formed in a thin shape without lengthening the outer dimension in the longitudinal direction, and the ventilation efficiency can be improved.

[Problem that the invention seeks to solve]

In a conventional ventilation system with a heat exchanger like the one above.

The thickness of the part housed in the ceiling is determined by the length of the diagonal of the cross section of the heat exchanger (4). In order to lower this, it is necessary to increase the length of the heat exchanger +4) in the stacking direction, so there is a problem that the external dimensions of the product in the longitudinal direction are long. There is also the problem that the ventilation can only be done in one direction, and the ventilation efficiency is not sufficient.

This invention was made in order to solve the above-mentioned problems.It can be formed into a thin shape without increasing the external dimensions in the longitudinal direction, and it can improve ventilation efficiency by improving air flow. The purpose of this invention is to provide a ventilation system with a heat exchanger.

[Means for solving problems]

Each side should face the ceiling panel.

Outside air outlets are provided on both sides of the ceiling panel, and an exhaust inlet is provided in the center.
