Abstract

PURPOSE:To enable simple regulation of an airflow of air to a value necessary to a necessary area in a room, by s method wherein an airflow regulating shutter is mounted to all or a part of air conditioning filters in a clean room. CONSTITUTION:Air conditioning filters 11, 12, and 13, with which an air conditioning filter 1 is formed, are capable of airflow regulation. The air-conditioning filters 11 and 13 positioned on 8 production line are regulated so that the airflow thereof is increased over that of the air-conditioning filter 12 positioned in a passage. A stationary shutter 2 is located above the air conditioning filters, with an airflow regulating screw 4 rotated, a gear 6 connected to the screw through a shaft 5 is rotated, a rack 7 is moved laterally, and a moving shutter 3 coupled with the rack is also moved lateral to change the numerical aperture of the shutter. In which case, a quantity of air in the direction of an arrow mark A passing a filter member is regulated, and produces air in the direction of an arrow mark B on the downstream side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clean room with a full-surface filter system.

[Conventional technology]

Inside the clean room, which uses a full-filter system, an air-conditioning filter is installed on the entire ceiling of the room, allowing air to enter the room through the filter and flow out from the floor. Conventionally, this type of air conditioning filter did not have a special mechanism for freely adjusting the air volume.

[Problem that the invention seeks to solve]

Normally, a clean room does not have a uniform air volume over the entire surface of the room due to production considerations. For example, the production line and aisles are differentiated, and a large air volume type air conditioning filter is installed in the former, and a small air volume type air conditioning filter is installed in the latter. The air volume was adjusted by using and installing them differently. Therefore, when the production layout changes, it becomes necessary to replace the air conditioning filter, which has the disadvantage that the construction period is long and the number of man-hours is large.

Another disadvantage is that during replacement, the air conditioning must be stopped, and the production line must be stopped during this time.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a clean room in which the m and amount of specific parts can be arbitrarily adjusted when changing the layout within the clean room.

[Means for solving problems]

In the clean room according to the present invention, at least a portion of the air conditioning filter provided throughout the room has a shutter that can adjust the air volume.

Now, if the shutter is installed on the entire surface of the air conditioning filter,
Although the degree of freedom in layout is maximized, the shutter may be provided only to the extent that changes in the layout can be considered in the future.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of an air conditioning filter installed in a clean room with a full-surface filter system.

The air conditioning filters 11 and 12゜13 constituting the air conditioning filter 1 are those that can be used for air flow investigation, and as shown in the figure, the air conditioning filters 11゜13i-11 located on the production line
: The airflow volume is adjusted to be louder than the air conditioning filter 12 located in the passage.

FIG. 2 is a sectional view of the air conditioning filters 11, 12, and 13. A fixed shutter 2 is provided at the top, and when the air volume adjustment screw 4 is turned, a gear 6 connected by a shaft 5 turns, the rack 7 moves left and right, and the movable shutter 3 connected to it also moves left and right, so that the aperture ratio of the shutter is adjusted. Since the amount of wind passing through the filter member as indicated by the upstream arrow A is adjusted,
It becomes the wind of arrow B downstream. Note that the O-ring 8 is provided to prevent upstream wind from leaking through the gap in the shaft 5.

〔Effect of the invention〕

As explained above, the clean room with the full filter system of the present invention can be adjusted to send only the necessary scenery to the necessary areas in the clean room by attaching air volume adjustment shutters to all or part of the air conditioning filters. can be done easily.

As a result, air conditioning was stopped due to layout changes.

Since there is no need to stop the production line, it is highly effective in improving production efficiency.
