is the floor of the building, 3 is the ceiling of the building, and 4 is the outside glass of the building's windows. There are an air supply outlet 6 and a return air intake 6 on the ceiling surface 3, and an air supply duct 8 that connects the air supply outlet 5 and the air handling unit main body 7 is present in the ceiling. The attic space also serves as a return air duct.

Reference numeral 9 denotes an outside air/exhaust partition plate in the air handling unit main body 7, which separates an outside air section from an exhaust section. The outside air part is the outside air intake port 10. Total heat exchanger 11° Total heat exchanger outside air intake damper 12. It is composed of an outside air intake chamber 13 in which outside air does not pass through the total heat exchanger 11 and an outside air intake damper 14. The exhaust section includes a total heat exchanger exhaust damper 15, the total heat exchanger 11, an exhaust damper 16 that prevents the exhaust gas from passing through the total heat exchanger 11, an exhaust chamber 1, and an exhaust port 18 located on the leeward side of the exhaust chamber 17. It is composed of

Reference numeral 19 denotes an air supply/return air partition plate, which distinguishes the air supply section from the return air section. The air supply section can be in contact with the outside air section via the total heat exchanger outside air intake damper 12 and the outside air intake damper 14, and the air supply room is 20 degrees F/L/21 from the windward side.
, cold/hot water coil 221 air supply fan 23, air supply port 24
It is more established. The air supply chamber 20 is located on the windward side of the air supply fan 23.

The return air section is opened from the windward side through the return air port 25. Filter 26, return air fan 27. Consists of a return air chamber 28 and a return air damper 29
The return air chamber 28 and the supply air chamber 20 are in contact with each other via. Further, the return air chamber 28 can be in contact with the exhaust section via the exhaust damper 16 and the total heat exchanger exhaust damper 15.

A return air duct 30 connects the ceiling surface 3 and the return air port 26 located in the air handling unit main body 7.

In the above configuration, when the air handling unit is in the cooling/heating mode, the total heat exchanger outside air intake damper 12 is in the open state, the outside air intake damper 14 is in the closed state, the total heat exchanger exhaust damper 16 is in the open state, and the exhaust damper 16 is in the open state. Closed state, return air damper 2

FIG. 5 shows the flow of air in the heating and cooling mode of the air handling unit.

The outside air entering the air handling unit main body 7 from the outside air intake port 10 undergoes heat exchange by the total heat exchanger 11, and then passes through the total heat exchange outside air intake damper 12 and enters the air supply chamber 20. Thereafter, dust is removed by a filter 21, the temperature is adjusted by a cold/hot water coil 22, and the air is sent into the room via an air supply port 24, an air supply duct 8, and an air supply outlet 5 by an air supply fan 23. Indoor air passes through the attic space from the return air intake 6 and is guided to the return air duct 30. The return air entering the return air port 25 of the air handling unit body 7 from the return air duct 30 is passed through the filter 26. It passes through the return air fan 2 and enters the return air chamber 28. Here, the same amount of outside air as the amount of outside air taken in from the total heat exchanger outside air intake damper 12 passes through the total heat exchanger exhaust damper 15 and the total heat exchanger 11 through the return air chamber 28, and is discharged from the exhaust port 18. On the other hand, the remaining return air enters the air supply chamber 20 via the return air damper 29, mixes with the outside air taken in from the total heat exchanger outside air intake damper 12, and is blown into the room as supply air.

Problems to be Solved by the Invention In such conventional configurations, indoor air-conditioned spaces are greatly affected by solar radiation from windows, etc., but no countermeasures are taken, and a large amount of energy is required for cooling or heating. This has the problem of requiring energy. Furthermore, no effort has been made to effectively utilize the energy from sunlight on the window side.

The present invention is intended to solve these problems, and aims to provide an air handling unit that effectively acquires and effectively utilizes solar energy that enters a room from a building's window surface. .

In the case of exhaust mode, the cooling condition is Hl<H2, H2-H3, and the heating condition is Hl>H2, H2>H3.
The damper 39 is controlled in the opening direction with respect to the exhaust chamber 17. The air that has passed between the outer glass 4 and the inner glass 31 is guided from the duct 36 to the exhaust chamber 17 through the duct 37, and is discharged outside from the exhaust port 18 of the air handling unit main body T.

In the recovery mode, the cooling condition is Hl<H2, H2>H3, and the heating condition is Hl>'2, H2<H3, and the damper 39 is controlled in the opening direction with respect to the air supply chamber 2Q. Therefore, the air that has passed between the outer glass 4 and the inner glass 31 passes from the duct 36 to the duct 38 to the air supply chamber 2.
o, and is collected indoors through the air supply port 24 of the air handling unit main body 7.

In this embodiment, a blind is used as the solar radiation variable means, but an electric curtain may be used as long as it can control the solar radiation into the room.
