Description

Ventilated raised floor

This disclosure relates to a raised floor, and in particular to a ventilated raised floor.

In clean rooms, people move and transport equipment and other operations on foot, which is easy to cause wear and static electricity to generate fine dust. In order to prevent dust and fine dust from being retained in clean rooms, high-tech industries use elevated floors most widely. For example: semiconductor wafer factories, IC test areas, optoelectronic mask laboratories, and biotechnology industries. Elevated floors are also called dissipative static floors. Elevated floors are mainly assembled by adjustable brackets, crossbeams, panels, etc. There is a certain range of suspended space between the horizontal floor and the panel, and this suspended space can be used in clean rooms.

Cleanrooms are mostly multi-story buildings, with an air supply system on the upper floor, a workshop in the middle, and an elevated floor under the workshop, making the lower floor a return air space or passage. When the cleanroom is in operation, the upper air supply system blows filtered air down to the workshop, and the air flows through the workshop, passes through the elevated floor system, reaches the lower return air space or passage, and then circulates to the upper air supply area, realizing an airflow loop in the closed cleanroom.

Most of the known technologies use round or rectangular holes in the elevated floor to achieve airflow. When the clean room needs airflow circulation with different flow rates and circulation rates, it is necessary to replace the elevated floor orifice plates with different ventilation rates, hole shapes and sizes. However, this action requires a lot of work to dismantle and replace the elevated floor, which will affect the normal operation of the clean room and increase costs.

The disclosed embodiment provides a ventilated elevated floor, which does not require dismantling the elevated floor, and is convenient for adjusting the ventilation flow rate and airflow circulation rate, thereby improving the convenience of use.
