Or the degree of cooling is lowered, preventing the temperature increase or decrease of the cooling air or heated air on the supply side due to the air on the discharge side.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(8) is a partition-type office desk, and the partition wall (3) is made of a heat insulating material and equipped with a thermoelectric element (2) having a Bertier effect in the center of the hollow panel (1) that constitutes the side wall. The space is divided into a supply side space (a) and a discharge side space Q) by the partition wall (3).

A supply side fan (4) is built into the supply side space (al), and a supply side fin (5) is arranged in contact with the - side of the thermoelectric element (2), and a supply side air suction port is provided at the bottom. (6), and an upper air outlet (7^) and a lower air outlet (7B) for supply side air are provided at the upper part.

On the other hand, a discharge side fin (8) is built in the discharge side space (b), and a discharge side fin (9) is disposed in contact with the thermoelectric element (2) and perpendicular to the supply side fin (5), - A discharge side suction port 0[I] is arranged at the lower part of the side part, and a discharge side blow-off port (11) is arranged at the top part of the other side part.

The thermoelectric element (2) is connected to a DC power source, and the fifth thermoelectric element (2) is connected to a DC power source.
As shown in the figure, the thermoelectric elements (2) are arranged in a staggered manner, and the thermoelectric elements (2) in each row are arranged at predetermined intervals along the elongated direction of the supply side fins (5), that is, the direction in which the supply side air flows. .

Since the illustrated embodiment is configured as described above, when a DC current is applied to the thermoelectric element (2) and the supply side fan (4) and the discharge side fan (8) are simultaneously driven, the suction port (6) is activated. ) The supply side air sucked into the supply side space (a) is gradually cooled or heated while passing through the supply side fins (5), and is then sucked out from the air outlet (7a) (7b). , a localized thermal environment can be obtained.

On the other hand, the discharge-side air sucked into the suction-side space (b) from the discharge-side suction port 0■ is discharged from the blow-off port (11).

Note that + of the DC power supply for the thermoelectric element (2).

By changing , hot air and cold air blowing can be switched.

An example of the use of the illustrated device will now be given.

When cooling the room, set the temperature of the air conditioner throughout the room to a slightly higher temperature. In this case, people who prefer slightly higher temperatures, such as elderly women, can obtain a comfortable thermal environment without using this device.

Also, people who feel hot with this setting use this device.

During cooling, the cold air tends to stay near the floor surface, so in such a case, the lower air outlet (7b) in the supply side space (a) is It is closed by a blade device, and cold air is blown out from the upper outlet (7a). You can feel more comfortable by directing the cold air to your upper body, especially your head. At this time, the cold air is at a slight speed, so it does not cause discomfort.

Note that the air outlet can also be made into a swinging device that can automatically change the wind direction.

Next, during heating, the entire room is air-conditioned at a slightly lower temperature, and those who prefer a cooler temperature can operate this device.

Generally, the lower body feels colder, so by closing the upper air outlet (7a) and blowing warm air from the lower air outlet (7b), you can cool the lower part of the top plate (1) of the office desk (A). Warm air is trapped inside, creating a comfortable environment where your head is cold and your feet are warm.

In either case, the exhaust air is blown out to the upper part of the room at a somewhat high blowing wind speed, and is sucked in through the inlet of the general air conditioner to handle the load.

In the above embodiment, as shown in FIG. 5, the thermoelectric elements (2) are arranged in a staggered manner, and the thermoelectric elements (2) in each row are
are arranged in series along the supply side fins (5) at predetermined intervals, and the discharge side fins (9) are arranged perpendicularly to the supply side fins (5), so that during cooling, the supply side fins ( The supply air passing through 5) passes through the heat absorption side of the plurality of thermoelectric elements (2) arranged in series and is gradually cooled.

At this time, the thermoelectric element (2) arranged in series with the exhaust side air
Since the surface facing the exhaust side space of the thermoelectric element becomes the heat radiation side, the temperature of the exhaust side air gradually rises, and when the temperature in the exhaust example is high, the cooling side of the thermoelectric element (2) The temperature also increases, making it impossible to lower the temperature of the supply side cold air.

However, according to the embodiment, since the thermoelectric elements (2) are arranged in a staggered manner, when the air on the discharge side passes through the discharge side fins (9), the -heat of one thermoelectric element (2) After passing through, the air passes between adjacent thermoelectric elements (2) in the next row, suppressing the temperature rise of the discharge side air, and as a result, preventing the temperature rise of the supply side cold air.

For the same reason as above, when the DC power supply to the thermoelectric element (2) is switched between + and - and hot air is blown from the supply side space, the temperature of the same hot air can be increased.

Although six thermoelectric elements (2) are used in the above embodiment, the number of thermoelectric elements (2) is determined by the required capacity of the device.

(Effects of the Invention) As described above, the present invention provides a supply-side space partitioned by a partition wall equipped with a thermoelectric element having a Peltier effect in a space inside a panel constituting a desk installed in an office room. has built-in supply-side fins and a supply-side fan, the discharge-side space has built-in discharge-side fins and a discharge-side fan, and the supply-side space and the discharge-side space are provided with an inlet and an outlet, respectively. This makes it possible to perform local heating and cooling according to individual preferences without using cold/hot water piping, refrigerant piping, etc., and eliminates uneven vertical temperature distribution in the room.

Furthermore, by using a thermoelectric element having a Peltier effect, switching between heating and cooling can be easily performed.

Furthermore, by configuring the air outlet in the supply side space as a pair of upper and lower air outlets, an ideal thermal environment for keeping the head cold and feet warm can be obtained.
