Clean room

Claim 2

A clean room for keeping clean interior air of an airtight main room (1) by circulating the interior air through a circulation path and an air conditioner (A1; A2) and filters disposed in the circulation path, which clean room is characterized by having at least one air-conditioner unit (A1; A2) built in the shell of the room behind part of the internal wall thereof, the air-conditioner unit being provided with an external casing (8) of a small thickness, the external casing being provided in the lower part of the room interior side thereof with an air inlet (8a1) and in the upper part thereof with an air outlet (8b1) fitted with a high-performance filter (8j), the casing being further provided therein with an air blower (8h), and the air blower being so adapted as to deliver forced air flow to the air outlet.

Claim 3

A clean room according to claim 1, characterized in that there are incorporated at least two air-conditioner units (A1, A2) and one of the two air-conditioner units incorporates in the casing (8) thereof a heat exchanger (i).

Claim 4

A clean room according to claim 2, characterized in that the two air-conditioner units (A1, A2) are disposed at positions opposed to each other across the internal space of said room.

Claim 5

A clean room for keeping clean interior air of an airtight main room by circulating the interior air through a circulation path and an air conditioner and filters disposed in the circulation path, characterized by: a plurality of gate-shaped frames (5) disposed in parallel in a prescribed direction as regularly spaced on a floor surface, an air-conditioner unit (A1; A2) built in at least one of the spaces intervening between the adjacent vertical members (5a, 5b) of the gate-shaped frames (5) and adapted to form part of the internal wall of the room and a control unit (B) built in one of the spaces intervening between the adjacent vertical members (5a, 5b) except for the space occupied by the air-conditioner unit and adapted to control the air-conditioner unit, wall panels (13) covering the spaces intervening between the adjacent vertical members of the gate-shaped frames except for the space occupied by the air-conditioner unit and the spaces falling within the vertical members of the gate-shaped frames (5) and wall panels covering the external parts of the gate-shaped frames positioned outside, a ceiling panel covering the upper open end of the airtight main room (1) enclosed with the wall panels, and means for tightly sealing the airtight main room, which air-conditioner unit being provided with an external casing (8) of a small thickness, the external casing being provided in the lower part of the room interior side thereof with an air inlet and in the upper part thereof with an air outlet fitted with a high-performance filter, the casing being further provided therein with an air blower, the air blower being so adapted as to deliver forced air flow to the air outlet, and the control unit being provided in a thin external casing thereof with mechanical items for control.

Claim 6

A clean room for keeping clean interior air of an airtight main room by circulating the interior air through a circulation path and an air conditioner and filters disposed in the circulation path, characterized by: a plurality of gate-shaped frames (5) disposed in parallel in a prescribed direction as regularly spaced on a floor surface, an air-conditioner unit (A1; A2) built in at least one of the spaces intervening between the adjacent vertical members (5a, 5b) of the gate-shaped frames (5) and adapted to form part of the internal wall of the room and a control unit (B) built in one of the spaces intervening between the adjacent vertical members (5a, 5b) except for the space occupied by the air-conditioner unit and adapted to control the air-conditioner unit, wall panels (13) covering the spaces intervening between the adjacent vertical members of the gate-shaped frames except for the space occupied by the air-conditioner unit and the spaces falling within the vertical members of the gate-shaped frames (5) and wall panels covering the external parts of the gate-shaped frames positioned outside, a ceiling panel covering the upper open end of the airtight main room (1) enclosed with the wall panels, and means for tightly sealing the airtight main room, which air-conditioner unit being provided with an external casing (8) of a small thickness, the external casing being provided in the lower part of the room interior side thereof with an air inlet and in the upper part thereof with an air outlet fitted with a high-performance filter, the casing being further provided therein with an air blower, the air blower being so adapted as to deliver forced air flow to the air outlet, and the control unit being provided in a thin external casing thereof with mechanical items for control.

Claim 7

A clean room according to claim 4, characterized in that the means for tightly sealing the gaps between the lower end of the internal wall and the floor surface of the airtight main room is a sheet adapted to cover the gap and the floor surface entirely.
