And it is exhausted (EA) to the outside of the heat exchange apparatus 20 through the return air discharge port 24.

On the other hand, a part of the return air RA blown and supplied to the first air distribution chamber 4-1 is supplied to the second air distribution chamber 4-2 through the damper 7 in which the open state is adjusted. Since the air supply fan 9 of the air supply chamber 5 is in operation, the outside air OA is sucked into the outside air intake port 23 by the suction force of the air supply fan 9, and passes through the heat exchanger 22. Heat exchanged with the return air (RA) passing through the cross) is heated and supplied to the second air distribution chamber (4-2) through the hot air outlet (26) and the damper (26-1).

A part of the return air RA supplied to the second air distribution chamber 4-2 and the warm outside air heated through the heat exchanger 22 are mixed in the second air distribution chamber 4-2, and the coil 8 It is purified by passing through, and is sucked into the air supply chamber 5 by the suction force of the operation air supply fan 9, and is supplied to the room as supply air SA.

In addition, as in the spring and autumn, when the outside air is fresher than the indoor air (gutter), and the air is to be discharged to the outside while supplying fresh air to the room without discharging the return air (RA) as follows, it is carried out as follows.

As described above, the heat exchanger 20 is operated together with the return fan built-in air conditioner 2-1, which is the air conditioner 2, and the heat exchanger 20 is a damper 26 of the hot air outlet 26. -1) is closed and the damper 29-1 of the bypass outlet 29 is opened, and the return fan built-in air conditioner 2-1 is similar to the embodiment illustrated in FIGS. 1A to 2. Since it works the same, a description of its operation relationship is omitted.

Since the air supply fan 9 of the air supply chamber 5 is operated in the heat exchanger 20, the outside air OA is sucked into the outside air intake port 23 by the suction force of the air supply fan 9, and passes through the heat exchanger 22. After the damper 26-1 is reached, the damper 26-1 is closed, so that the outside air OA sucked to the outside air intake 23 cannot pass through the inside of the heat exchanger 22.

Therefore, the outside air OA sucked moves around the heat exchanger 22 toward the bypass outlet 29, and the outside air OA sucked to the bypass outlet 29 is damped through the damper 29-1. The outside air OA which flows into the second air distribution chamber 4-2 (intake) and directly flows into (intakes) the second air distribution chamber 4-2 is supplied to the air supply chamber by the suction force of the air supply fan 9. While being sucked into (5), it is supplied to the room as a supply air SA.

An air conditioner having a heat exchanger formed to be supplied to an air distribution chamber. After returning the introduced outside air by a filter and heating it by a coil, it is forced to blow air by the air supply fan to supply the room with a built-in return fan. In the heat exchanger, the return fan built-in air conditioner and the heat exchanger are integrally formed, and the internal air supplied to the return fan built-in air conditioner is circulated to the heat exchanger, In an air conditioner equipped with a heat exchanger for supplying the room by a return fan built-in air conditioner, The heat exchanger is integrally installed on the upper side of the return fan built-in air conditioner, and the first air distribution chamber and the second air distribution room of the return fan built-in air conditioner are connected to the return air inlet and the outside air heat outlet of the heat exchanger. The heat exchanger is connected to each other, and the heat exchanger is formed so as to communicate with the outside air inlet of the heat exchanger by the partition wall formed at the outer end of the heat discharge air outlet of the heat exchanger from the outer end of the heat exchanger to the second air flow chamber. Further includes a bypass outlet, And a damper at each of lower ends of the heated outdoor air discharge port and the bypass discharge port, the air conditioner having a heat exchanger for controlling the flow of the heated outdoor air exchanged from the heat exchanger to the outside air inlet. delete delete The method according to any one of claims 1, 4 or 5, Heat exchanger installed in the heat exchanger is an air conditioner with a heat exchanger, characterized in that the longitudinal or transverse type.
