Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a local air-conditioning and dust removal device for a clean room or constant temperature room defined in a factory building.

(Conventional technology) As the demand for improved product precision increases and work becomes more detailed, factories are becoming increasingly clean room-based and constant-temperature nitriding.

In conventional air conditioning systems, the entire factory is air-conditioned as one room, making it a clean room and maintaining a constant temperature.

This method consumes a large amount of energy in large-scale factories, and it is difficult to uniformly air-condition the entire space.

For this reason, it has been proposed to define a local clean room or constant temperature room at any location within the factory.

(Problems to be Solved by the Invention) The local clean room or constant temperature room is effective when installed alone, but when multiple clean rooms and constant temperature rooms are installed in a factory building, each clean room and constant temperature room An air conditioning unit is required for each.

However, the problem is that air conditioning units take up a lot of space, water cooling systems cannot be used if they are to be moved, and energy consumption is large, and the air conditioning units must be moved when moving clean rooms or constant temperature rooms. There is.

(Means for Solving the Problems) The present invention was proposed to solve these problems, and includes an air blower connected to a clean air supply device and provided with air intake ports at predetermined intervals. A duct is arranged in a factory building in a direction that extends or crosses the building, and a clean room defined in the building is connected to an air outlet of the blower duct by a connecting duct. This relates to local air conditioning dust removal equipment.

(Function) As described above, in the present invention, a ventilation duct with air intake ports provided at predetermined intervals is provided in a factory building in a longitudinal or transverse direction of the same building, and the ventilation duct is is connected to the clean air supply section, and the duct is connected to a clean room or constant temperature room defined in the factory building via a connecting duct to the air intake port of the nearest ventilation duct, and the clean air supply section Clean air supplied to the ventilation duct is supplied to a local clean room or constant temperature room through the connection duct, and local air conditioning and dust removal are performed in the local clean room or constant temperature room defined within the factory building. It is.

(Effects of the Invention) According to the present invention, among the air intake ports connected to a single clean air supply unit and arranged in a row in the ventilation duct arranged in the factory building, Clean air is supplied to the clean room or constant temperature room from the nearest air outlet through a connecting duct, so multiple clean rooms or constant temperature rooms can be installed at any location within the factory building. In addition, the air conditioning units required for each local clean room or constant temperature room are no longer required, space is saved, and the local clean room or constant temperature room can be easily moved. Able to adapt to changes.

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

(1) is an air conditioning equipment room, (2) is a factory building, and inside the air conditioning equipment room (1) are an air conditioner (3), a blower (4), and a filter (
5) A good clean air supply system is installed. Note that the filter (5) is omitted when a constant temperature room is targeted.

A required number of ventilation ducts (6) are installed in advance in the factory building (2) along the longitudinal direction of the building, and each of the ventilation ducts (6) is connected to the filter (5), and Air intake ports (7) at predetermined intervals along the length
are arranged in a row, and the plate outlet (7) is sealed with a lid (8) when not in use. Further, the duct (6) is provided with an on-off valve (9) for controlling the flow of air.

The above-mentioned ventilation duct (6) is installed on the ceiling or wall of the factory building (2), but if a ceiling-running duct is installed or if an air intake port cannot be installed in a large space, it may be placed under the floor. Pass the ventilation duct (6) through. If an underfloor duct system is adopted, it should be of a load-bearing type in consideration of the fact that people, carts, etc. will run over the outlet (7).

At work locations that require a clean room or temperature-controlled room, and where machine tools (a) are installed, a local clean room
The connecting duct (131) attached to the same building αI is connected to the air outlet (7) in the nearest ventilation duct (6).

Since the illustrated embodiment is constructed as described above, air whose temperature is controlled by the blower (4) and purified by the filter (5) is supplied to the blower duct (6),
Clean air is supplied to the clean room via the connection duct α4 connected to the air intake port (7), and local air conditioning and dust removal of the clean room α2 are performed.

In addition, when there are many ventilation ducts (6), a plurality of clean air supply devices are also provided, and the operation of each device is controlled depending on the presence or absence of load to prevent energy loss.

When this device is applied to a constant temperature room, the load may differ in each local constant temperature room, so the temperature sensor α4 installed in each room
) detects the internal temperature, opens and closes the gully α group at the air outlet (7), and installs a fan (16) to adjust the speed of the air flow. Alternatively, a portable small air conditioner may also be used.

If there is a large difference in the load between each room or a large load fluctuation, or if you want to arbitrarily set the temperature in each room, the ventilation duct (6) should be configured with two parallel ducts for heating and cooling. However, they may be mixed at an appropriate ratio at the air outlet (7).

In addition, the ventilation ducts installed under the ceiling or under the floor can be arranged not only in parallel but also in a grid pattern. Air can also be sent via the shortest route only to (7).

When changing the layout of the factory, the desired purpose can be easily achieved by moving the shed Uυ and connecting the connecting duct a3 to the nearest air outlet (7).

In this way, according to the above embodiment, a local clean room α■ or a constant temperature room is defined at any location within the factory building (2), and the air conditioning unit that was necessary for the lean room or constant temperature room, respectively, is installed. This eliminates the need for cleaning, saves space in the factory building (2), makes it easy to move the local clean room or constant temperature room, and makes it easy to change the layout in the factory building (2).

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .

FIG. 2 is a plan view showing an example, and FIG. 2 is a longitudinal sectional view thereof.
