BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system for air conditioning a highly airtight and highly insulated room.

[0002]

2. Description of the Related Art Ventilation is generally performed by exchanging indoor air and outdoor air for the purpose of keeping indoor air clean. However, when ventilating an air-conditioned room, if unconditioned outdoor air is introduced into the room while conditioned room air is exhausted, it is inevitable that the air conditioning load of the room will increase.

Therefore, conventionally, after heat exchange is performed between the outdoor air and the indoor air, it is widely performed that the heat-exchanged outdoor air is introduced into the room while the indoor air is discharged to the outside. ing.

That is, while an air conditioner having a heat exchanger is installed at a predetermined place such as an attic or a rooftop,
In order to reliably introduce the sucked outdoor air into the room from the air conditioner, the air conditioner and each room are connected by an air supply duct. Furthermore, in order to reliably suck the indoor air from each room to the air conditioner without letting it escape from the gap between the rooms,
The air conditioner and each room are connected by an exhaust duct.

In this way, by supplying the outdoor air conditioned by the exhausted indoor air to each room,
An increase in the air conditioning load of each room is suppressed.

[0006]

However, in the above-mentioned prior art, since the ventilation air conditioner and each room are connected by both the air supply duct and the exhaust duct, the total length of these ducts is relatively long. It cannot be avoided. Therefore, it is difficult to reduce the cost required for the duct itself and the cost required for installing the duct.

The present invention has been made in view of the above problems, and an object of the present invention is to suppress the increase of the air conditioning load in the room as much as possible by devising the structure of the air conditioning system. At the same time, the total length of the duct to be installed is shortened to reduce the cost.

...) is switched to air-conditioning operation or heating operation.

-Cooling operation-First, the cooling operation will be described. As shown by the solid line in FIG. 2, in the cooling operation, the first four-way switching valve (51) and the second four-way switching valve (52) are each switched to the first state. The air conditioner (10) sucks the outdoor air through the outdoor air intake (10a). The sucked outdoor air is discharged from the duct (25),
It is guided to the moisture absorption section (32) of the dehumidification mechanism (30) through the first four-way switching valve (51) and the first duct (25a). In the moisture absorbing section (32), moisture is adsorbed on the outdoor air by the solid adsorbent to be dehumidified. The dehumidified outdoor air continuously passes through the first duct (25a) and is sucked into the suction side of the compressor (21).

After the outdoor air is compressed by the compressor (21), it is cooled by the cooling heat exchanger (4) through the duct (25).
