〔Example〕

The present invention will be explained below based on the illustrated embodiments.

FIG. 1 shows an embodiment of a personal air conditioner 1 according to the present invention, in which a vortex tube 3 is incorporated into a partition 2 used to partition a personal space in an office or the like. The partition 2 is fixed by appropriate means onto the floorboard 4 at the location where the personal air conditioner 1 is installed, and a work desk 5 is placed in front of it. A flexible duct 6 is installed at the tip of the vortex tube 3.
One end of is connected. The other end of the flexible duct 6 passes through the floor plate 4 and is connected via a one-touch cover 7 to a connection port 10 of a compressed air duct 9 which is disposed under the floor 8 and which allows compressed air p<< to flow through the inside of the duct 3. Compressed air is thus supplied into the vortex tube 3 from the compressed air duct 9.

This vortex tube 3 is a device that can easily generate low temperature air and high temperature air.

6 and a hot air flow rate control valve 17. By blowing compressed air of several atmospheres into the vortex tube 3, it is possible to obtain air having a temperature lower or higher than that of the compressed air that has flowed in. That is, the compressed air blown into the vortex tube 3 from the compressed air blowing pipe 12 becomes a high-velocity spiral flow within the vortex tube 3 and moves in the direction of lower pressure (in the direction of the hot air outlet 16). . then.

Due to the spiral rotational movement, the speed of the air flow increases from the center to the outside of the vortex tube 3, and the pressure also increases from the center to the outside. In the case of a deceptive spiral flow, internal friction causes heat to flow outward from the center, causing the air in the center to lose heat and become cooler, while the air outside the vortex gains heat from the inside. This results in high temperatures.

The high temperature air is directly discharged from the hot air outlet 16.

Conversely, the low temperature air in the center of the tube is discharged from the cold air outlet 14. In addition, the compressed air inflow switching valve 13 is 0N10.

Next, the party room 2 is a hollow housing, and the interior is partitioned into two spaces, a cold air chamber 19 and a hot air chamber 20, by a partition plate 18. The cold air chamber 19 has a cold air outlet 21 at the upper front and a cold air outlet 22 at the upper surface. On the other hand, the hot air chamber 2o has a hot air outlet 23 at the lower front.
It also has a hot air exhaust port 24 on the top surface. These cold air outlets 21. Opening/closing dampers 21", 22', 23 are provided at the cold air exhaust port 22, the hot air intake port 23, and the hot air exhaust port 24, respectively.

The vortex tube 3 is hollow so as to pass through a partition plate 18 in the center of the party scene 2 so that its cold air outlet 14 is placed in the cold air chamber 19 and the warm air outlet 16 is placed in the warm air chamber 20. Supported. Further, control switches are lined up at appropriate positions on the front of the particiran 2, and by turning ON the 0N10FF changeover switch 25 linked to the compressed air inflow changeover valve I3 of the vortex tube 3 by an appropriate means (not shown). Compressed air flows into the vortex tube 3, and cold air and hot air are supplied to the cold air chamber 19 and the hot air chamber 20, respectively. Also.

The combination of opening and closing of the four opening/closing dampers 21'', 22'', 23', and 24° is selected by the cold air/warm air changeover switch 26 to switch the extraction of cold air/warm air.

That is, cold air/? The M wind changeover switch 26 switches the respective dampers 21', 22°, and 23' by appropriate means (not shown).

23 is opened, and the other side is the cold air intake port 21 and the hot air exhaust port 24.
dampers 21' and 24' are now closed. This allows the i-wind to be supplied to the feet of the worker.

Unnecessary cold air is exhausted towards the ceiling. In addition, when using the vortex tube 3, both cold air and warm air are always generated, but the unnecessary hot air or cold air exhausted toward the ceiling is the main source of uniform heating and cooling inside the building. It can be treated using an air conditioning system.

Incidentally, if a large number of connection ports IO of the compressed air duct 9 are provided in advance at appropriate intervals, and if the floor plate 3 is configured as a free access floor.

Even if the location where the personal air conditioner 1 is installed is changed, it can be handled flexibly.

FIG. 4 shows the personal air conditioner I according to this embodiment installed in a building. Therefore, air compression @28. An exhaust air W129° exhaust-compressed air heat exchanger 30 is installed. Air pressure 11fa28
A compressed air duct 9 extends from there.

The compressed air duct 9 is connected to an exhaust gas-compressed air heat exchanger 30, and extends to each floor via the exhaust gas-compressed air heat exchanger 30. Further, a first switching pulp 31 is inserted between the compressed air duct 9 and the exhaust-compressed air heat exchanger 30. Furthermore, the compressed air duct 9
is branched at a position before the first switching pulp 31, and the branched compressed air duct 9a is connected to the compressed air duct 9 again near the outlet of the exhaust-compressed air heat exchanger 30. .

The branched compressed air duct 9a has a second switching valve 32 in the middle thereof. When the second switching valve 32 is closed and the first switching pulp 31 is opened, the compressed air supplied from the air compressor 28 passes through the exhaust-compressed air heat exchanger 30 and is sent to each floor. In contrast, the first switching pulp 31 is closed and the second switching valve 32 is opened.
When the air is opened, the air is transported to each floor without passing through the exhaust/compressed air heat exchanger 30.

Next, the compressed air duct 9 branches for each floor and extends to the underfloor 8 of each room. and the compressed air duct 9
A plurality of connection ports 1o are provided at appropriate intervals, and the connection ports 10 are connected to a vortex tube 3 installed in the particiran 2 via a flexible duct 6.

Further, an exhaust duct 33 extends from the exhaust fan 29 installed in the tower building 27, and the TS exhaust duct 33 is connected to an exhaust air-compressed air heat exchanger 30, and the exhaust air-compressed air heat exchanger 30 is relayed. Later, it heads downstairs, branching out on each floor and extending to the attic 34 of each room. The branched exhaust duct 33 is connected to an exhaust suction port 35 provided near the ceiling.
is connected to. An exhaust adjustment damper 36 is provided in the middle of this branched exhaust duct 33. The exhaust adjustment damper 36 is equipped with a static pressure detector 3 that constantly monitors the static pressure in the room.
It is linked to 7.

Compressed air flows into the room when the personal air conditioner 1 is used, but the exhaust adjustment damper 3G adjusts the exhaust so that the pressure in the room is always positive based on the command from the static pressure detector 37. Note that the power consumption of the exhaust fan 29 can be reduced by controlling its rotation speed using an inverter.

The building also has main air conditioning equipment.

For example, a cooling tower 38 is installed in the tower building 27, a heat storage tank (not shown) is installed in the basement, and a ceiling 38 is installed in each floor of the building.
A fan coil unit 39 is installed in the building, and the main air conditioning equipment cools and heats the entire building. In addition to such water heat source air conditioning equipment, air heat source air conditioning equipment can of course also be applied.

With the above configuration, a method of using the personal air conditioner 1 according to this embodiment will be explained. First, when cooling the entire interior of a building, uniform cooling is performed by the main air conditioning equipment. In parallel with this, personal air conditioner 1
Individual cooling is performed using That is, the air pressure wi
By operating the compressor 28, outside air is taken into the air compressor 28, and! The compressed air produced by the f-air compressor 28 flows through the compressed air duct 9, and the compressed air is supplied to each floor. During this cooling, the second switching valve 32 is closed and the first switching valve 31 is opened, so that the compressed air passes through the exhaust air-compressed air heat exchanger 3°. As a result 1. The compressed air, which is high temperature because it is created by compressing outside air, comes into contact with the exhaust air from the cooled room and exchanges heat, so it is cooled to a temperature close to room temperature. Individual cooling efficiency using the air conditioner 1 can be improved. The compressed air supplied to each floor is supplied into the vortex tube 3 via a compressed air duct 9 and a flexible duct 6 arranged under the floor 8 of each floor. As described above, the vortex tube 3 is housed in the partition 2 fixed on the floorboard 3, and supplies cold air to the cold air chamber 19 of the partition 2, and hot air to the hot air chamber 20 of the partition 2. Then, as described above, the damper 21' of the cold air outlet 21 of the partition 2 is opened and the cold air is blown toward the upper body of the worker to cool each individual.
On the other hand, unnecessary hot air is discharged upward by opening the damper 24° of the hot air exhaust port 24 and is processed by the main air conditioning equipment. When cooling, the damper 22' of the cold air exhaust port 22 is closed to prevent the cold air from escaping upward, and the damper 23' of the a-air outlet 23 is closed to prevent hot air from escaping the worker. Prevent it from flowing under your feet. Indoor exhaust is achieved by sucking in indoor air from the exhaust suction port 35 by the exhaust fan 29 and discharging it to the outside through the exhaust duct 33.

As mentioned above, compressed air in this embodiment is generated using outside air, so outside air is supplied together with cold air to a room where one person is present and air supply is essential. Load can be reduced and energy can be saved. Next, when heating the inside of a building, contrary to 1 or more,
The main air conditioning equipment performs overall heating, and in parallel, individual heating is performed using the personal air conditioner 1. In this case, the first switching valve 31 is closed and the second switching valve 32 is kept open, so that the high temperature compressed air supplied by the air compressor 28 passes through the exhaust-compressed air heat exchanger 30. Since the air is supplied to the vortex tube 3 without any heating, the efficiency of individual heating using the personal air conditioner 1 can be improved. Then, by opening the damper 23' of the hot air outlet 23 of Particiran 2, warm air is supplied to the feet of the worker and heating is performed for each individual. 22゛ is opened and released upward and processed by the main air conditioning equipment.

During heating, the damper 24' of the hot air outlet 24 is closed to prevent hot air from escaping upwards, and the damper 21' of the cold air outlet 21 is closed to prevent cold air from flowing toward the worker. Prevent it from flowing.

As described above, if the personal air conditioner 1 of this embodiment is used, cold air and hot air can be taken out according to each individual's preference, and the UR section of heating and cooling can be adjusted individually.

Furthermore, if the personal air conditioner 1 of this embodiment is used, the difference between the temperature inside the building cooled and heated by the main air conditioning equipment and the outside temperature can be made smaller than before, while maintaining the comfort level of each individual. This can reduce the heat load required.

By opening the cold air outlet and the hot air outlet, and by closing the cold air outlet and the hot air outlet, the hot air is extracted. Cold air/
Hot air can be taken out freely. Furthermore, while maintaining personal comfort, it is possible to significantly reduce the heat load required by the main air conditioning method that uniformly cools and heats the entire building or each floor, thereby achieving energy savings.

In addition, the compressed air supplied to the vortex tube is
When cold air is taken out, heat is exchanged with the exhaust air cooled in the cooling area, so the compressed air is cooled to a temperature close to the exhaust gas temperature, improving cooling efficiency.
