DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OA equipment exhaust heat utilization apparatus, and more particularly to an OA equipment exhaust heat utilization apparatus that facilitates cooling and heating control of an entire room.

[0002]

2. Description of the Related Art Conventionally, a system using exhaust heat of OA equipment is intended only for heating.

For example, in the air circulation device described in Japanese Utility Model Laid-Open No. 06-073629, a method has been proposed in which the exhaust heat of OA equipment is sucked in through an exhaust duct, and air is blown in a foot direction or an upward direction. Thereby, it is possible to supplementally heat the room during heating and to locally heat around the desk during cooling.

[0004]

However, the above-mentioned prior art has the following problems.

[0005] First, it is effective when the room temperature is low, such as in winter, but it is not necessary to use it when the room temperature is high, and since it does not have an exhaust function, the exhaust heat generated from the OA equipment cannot be removed. Therefore, there is a problem that the usable period is limited.

Also, although each partition has an air blowing function, it does not have a temperature control function, so that a difference between the OA equipment that generates heat and the one that does not generate a temperature difference in each partition. . Therefore, there is a problem that the temperature cannot be controlled over the entire floor.

Accordingly, an object of the present invention is to provide an OA equipment exhaust heat utilization device which facilitates cooling and heating adjustment of an entire room, not locally, in order to solve the above-mentioned problem.

[0008]

In order to achieve the above-mentioned object, an exhaust heat utilization apparatus for OA equipment according to the present invention is connected to an exhaust port of an OA equipment, and inhales exhaust heat from the OA equipment without leaking to the surroundings. Exhaust suction device, an internal exhaust fan that stores the exhaust heat sent from the exhaust suction device and sends the stored exhaust heat to each floor, and an external fan that exhausts the stored exhaust heat to the outside when unnecessary. An exhaust fan, an exhaust heat storage tank internally provided with a storage tank temperature sensor for monitoring the temperature in the tank, a room temperature sensor installed on each floor to monitor the temperature of each floor, and a storage tank sensor and a room temperature sensor. A temperature control unit that monitors temperature information and controls the operation of the internal sending fan and the external exhaust fan, so that the temperature at a location where OA equipment is concentrated does not locally rise.

[0009] The temperature control section may determine whether the temperature information from the storage tank temperature sensor is equal to or lower than a preset temperature, or all the temperature information from the room temperature sensors on each floor is equal to or higher than the preset temperature. In the case, the external exhaust fan is operated to exhaust the exhaust heat to the outside, the temperature information from the storage tank temperature sensor is higher than a preset temperature, and the temperature information from the room temperature sensor of each floor is preset. When the temperature is equal to or lower than the temperature, it is preferable to operate the internal sending fan to send exhaust heat to each floor.

[0010]

[0011]

[0012]

Further, it is preferable that a plurality of room temperature sensors and a plurality of internal sending fans are provided.

[0014]

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing the configuration of an embodiment of an OA equipment exhaust heat utilization apparatus according to the present invention. The exhaust heat utilization device 1 includes an exhaust suction device 2, an exhaust heat storage tank 3, and a storage tank temperature.
It comprises a sensor 4, an external discharge fan 5, an internal delivery fan 6, a room temperature sensor 7, and a temperature control unit 8. The exhaust gas suction device 2 is connected to an exhaust port of the OA device, sucks all the exhaust gas from the OA device, and sends the exhaust gas to the exhaust heat storage tank 3.
Savings bath temperature sensor 4 on the inside of the exhaust heat savings tank 3 is discharged
The temperature in the heat storage tank 3 is monitored. The external exhaust fan 5
If you savings tank temperature sensor 4 has issued the information that is a temperature below a preset operates when you are out information that temperature sensor 7 is a temperature greater than or equal to the preset, the exhaust heat savings tank 3 Exhaust air to the outside.
The internal sending fan 6 operates when the room temperature sensor 7 outputs information equal to or lower than a preset temperature. The temperature control unit 8 monitors temperature information from each sensor and controls the operation of the external discharge fan 5 and the internal delivery fan 6.

[0016]

Next, the operation of the embodiment of the present invention will be described with reference to FIG.

In the OA equipment exhaust heat utilization apparatus of the present invention, an exhaust suction device 2 for sucking the exhaust gas of the OA equipment, an exhaust heat storage tank 3 for storing the exhaust heat, and a control of sending the indoor heat to the outside. And a temperature control unit 8. The exhaust suction device 2 sucks the exhaust gas from the exhaust port of the OA device without leaking to the surroundings. The sucked exhaust gas is temporarily stored in the exhaust heat storage tank 3. The temperature control unit 8 determines whether the temperature from the storage tank temperature sensor 4 is equal to or lower than a preset temperature, or if all the temperature information from the room temperature sensors 7 in each room is equal to or higher than the preset temperature. The air is exhausted by the external exhaust fan 5. When the information of the storage tank temperature sensor 4 is equal to or higher than the preset temperature and the room temperature sensors 7 in each room are equal to or lower than the preset temperature, warm air is sent into the room by the internal sending fan 6.

Next, another embodiment of the present invention will be described.

By increasing the installation of the room temperature sensor 7 and the internal blower fan in the same floor, it is possible to make the temperature of the entire floor uniform.

[0020]

As described above, according to the present invention, the provision of the exhaust suction device prevents the exhaust heat of the OA equipment from spreading to its surroundings. Accordingly, it is possible to prevent a local rise in temperature at a location where the OA equipment is concentrated, and also to prevent the surrounding dust from being diffused by the exhaust wind.

Further, the provision of the exhaust heat storage tank , the monitoring function of the room temperature and the blower fan makes it possible to blow warm air into a room having a lower temperature. Thereby, there is an effect that it is possible to save the indoor heating cost.

Further, it is said that the warm exhaust air taken in when heating is not required is discharged outside. Thereby, since the exhaust heat is absorbed, there is an effect that cooling can be efficiently performed in summer.
