专利汇可以提供Vertical laminar-flow clean room of flexible design专利检索，专利查询，专利分析的服务。并且A vertical laminar-flow clean room is contained within a bounding enclosure which is substantially airtight. The clean room floor is raised and has apertures therein. The floor and the bottom of the bounding enclosure form an air-receiving plenum. A dropped ceiling is formed of an assembly of blower-hood-filter units, with the space directly above the dropped ceiling constituting an air-supply plenum. Air return plenums are contained entirely within the bounding enclosure and preferably incorporate prefilters and air-conditioning equipment, and the air return plenums connect the air-receiving plenum to the airsupply plenum. The blower-hood-filter units and air return plenums are all of a similar size, in order to facilitate a modular-type of construction and flexibility of design.，下面是Vertical laminar-flow clean room of flexible design专利的具体信息内容。

权利要求

1. A vertical laminar-flow clean room comprising: a. a bounding enclosure formed by sidewalls, a top wall, and a bottom wall, said bounding enclosure being substantially airtight except as to permit necessary personnel and material ingress and egress and to provide for makeup air which may be introduced therein in a controlled fashion; b. a raised floor having a periphery which abuts said sidewalls and which constitutes the floor for said clean room, said raised floor having apertures therein to permit airflow therethrough, said raised floor positioned over said bottom wall, and the space between said raised floor and said bottom wall constituting an air-receiving plenum; c. an air-moving filter system having a periphery which abuts said sidewalls and a bottom surface which constitutes the ceiling for said clean room, said air-moving filter system supported beneath said top wall and comprising a plurality of blower-hood-filter assemblies, said blower-hood-filter assemblies each comprising a hood unit having an open air inlet portion and an air outlet portion terminating in highefficiency air filter means which comprises a part of said ceiling, with the overall lateral dimensions of each said blower-hood-filter assembly as measured at that portion thereof which comprises a part of said ceiling being the same, and a blower unit operable to move air from said open air inlet portion and to and through said high-efficiency air filter means, the bottom surface of said air-moving system as viewed from said raised floor comprising a plurality of said air filter means, an air-supply plenum formed by the space between said air-moving system and said top wall, and the only passage for air directly from said air-supply plenum and into said clean room being through said blower-hood-filter assemblies; and d. vertically disposed air return plenum duct means located entirely within the confines of said bounding enclosure and connecting said air-receiving plenum and said air-supply plenum in an airtight fashion, and each said air return plenum duct means having the same overall lateral dimensions as said overall lateral dimensions of each said blower-hood-filter assembly in order to be readily assembled therewith and interchangeable therewith.

2. The clean room as specified in claim 1, wherein air-conditioning equipment is mounted within said air return plenum duct means.

3. The clean room as specified in claim 2, wherein controls for said air-conditioning equipment and controls for the blower units of said blower-hood-filter assemblies are located on the exterior lateral surface of said air return plenum duct means.

4. The clean room as specified in claim 1, wherein prefilter means is mounted within said air-return plenum duct means.

5. The clean room as specified in claim 4, wherein each said air return plenum duct means is located in the immediate area it is intended to serve, and for each said air return plenum duct means there are provided from about eight to 14 of said blower-hood-filter assemblies thereby to eliminate long passages for return air movement.

6. The clean room as specified in claim 5, wherein for each air return plenum means, there are provided about 10 of said blower-hood-filter assemblies.
