The exhaust heat exhaust in the double floor 3 is exhausted to the outside through the exhaust damper 15 and the exhaust heat exhaust duct 14 when the temperature in the room is high in the summer, and when the temperature in the room is low in the winter. Is supplied indoors through the perimeter return air unit 12. This makes it possible to effectively use the exhaust heat exhausted from the OA equipment 5 for heating the room and to air-condition the room.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system, and more particularly to a ceiling blowing air conditioning system for double floors such as free access floors.

[0002]

2. Description of the Related Art Recently, in an intelligent building or the like in which a large number of OA devices such as personal computers and workstations are installed, a floor is duplicated on a free access floor or the like to provide power wiring for OA devices and communication cables such as LAN. Wiring between the double floors is becoming more common.

[0003]

Under the present circumstances, the heat exhausted from these OA devices is often exhausted into the room as it is, and the heat load of the air conditioner is increasing. As a result, there are cases in which the interior part of the building is annually cooled and the perimeter part is selectively used for cooling and heating depending on the season. Conventionally, when cooling and heating coexist, a cold heat source and a warm heat source are prepared respectively. However, if the heat load of the intea portion can be used as the heat source for the perimeter heating in the winter, energy can be saved, but energy is wasted by using the cold heat source and the warm heat source at the same time.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a system capable of utilizing the exhaust heat of OA equipment or the like as a heat source for heating in the winter and conserving energy while air conditioning.

[0005]

In order to achieve the above-mentioned object, the air conditioning system of the present invention is provided with a heat generating device such as an OA device in a room, and exhaust heat exhausted from the heat generating device is provided in a double floor. A suction mechanism for sucking in, a discharge mechanism for discharging the exhaust heat exhaust gas sucked into the double floor through the suction mechanism to the outside when the temperature in the room is high such as in summer, and the suction mechanism. And a supply mechanism for supplying the exhaust heat exhausted through the double floor to the room when the temperature in the room is low such as in winter.

[0006]

The exhaust heat exhausted from the OA equipment or the like is supplied into the double bed through the suction mechanism. Exhaust heat exhaust in the double floor is exhausted outside when the room temperature is high such as in summer, and is supplied indoors when the room temperature is low such as in winter. Therefore, it is possible to perform air conditioning in the room while effectively utilizing the energy of exhaust heat exhausted from the OA equipment and the like.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic sectional view showing an embodiment of the air conditioning system of the present invention. In FIG. 1, an OA device 5 is installed via a partition 4 in an office room 1 between a ceiling 2 and a free access floor 3, and an air conditioner 6 is installed on a side wall of the office room 1. There is. The air conditioner 6 includes an air conditioner damper 7, a filter 8 provided on a side wall of the office 1.
The hot and cold water coil 9 and the air conditioner fan 10 are provided,
The air from the air conditioner 6 is supplied into the office room 1 via the air supply unit 11 installed on the ceiling surface.

A perimeter air supply unit 12 and a perimeter return air unit 13 are installed at the corners of the free access floor 3 and the ceiling 2, respectively, and correspond to the perimeter air supply unit 12 of the free access floor 3. An exhaust heat exhaust duct 14 having an exhaust damper 15 is installed at the corner. In addition, in the figure, 16 indicates a window, and a suction port for exhaust heat exhausted from the OA equipment 5 is formed in the upper part of the partition 4, and a heat exhaust passage is formed in the partition 4 in communication with this suction port. Is formed, and the exhaust heat exhaust fan 17 is installed in communication with this passage.

Next, the operation of the embodiment configured as described above will be described. Exhaust heat exhaust from the OA equipment 5 is sucked by the exhaust heat exhaust fan 17 through a passage in the partition 4 in which a suction port is formed, and is sent to a double floor partitioned by the free access floor 3. The exhaust heat exhaust from the OA equipment 5 is exhausted to the outside through the exhaust damper 15 and the exhaust heat exhaust duct 14 in the summer. In winter,
The exhaust heat exhausted from the OA equipment is supplied into the office room 1 for heating the perimeter by the air supply unit 12. Further, in the winter when the building is open weekly, all floors are heated for a predetermined time. At this time, the perimeter return air unit 13 is driven and the exhaust heat exhausted from the OA equipment 5 is heated to the entire heating. Will contribute.

In the above-mentioned embodiment, an example in which the air supply unit and the return air unit are installed in the perimeter zone has been shown. However, in the present invention, these units are installed not only in the perimeter zone but in any zone. You may. Further, although the case where the OA equipment is used as the exhaust heat exhaust source in the room is shown, it is not limited to the OA equipment and may be a heat generating equipment installed indoors. The device is not limited to the suction port formed in 1., but may be any means that is installed near the heat-generating device and has a predetermined suction port and communicates with the exhaust heat exhaust fan.

[0011]

As described above, according to the air conditioning system of the present invention, when the indoor temperature is high, such as in the summer, the exhaust heat exhausted from the heat generating equipment such as OA equipment is discharged to the outside, and in the winter or the like. When the temperature in the room is low, exhaust heat exhausted from the heat generating device such as the OA device can be supplied to the room, so that the room can be air-conditioned while saving energy.
