Abstract
Abstract An economical and efficient air conditioning system for Supplying clean air to equipment, such as a main frame comPuter, comprises a row of units (10, 11, 12) arranged side by side. Each unit (1) has an impeller (14) which draws air in hrough a filter (15) and forces it through cooling means (16) o underfloor ducts which supply the equipment. Temperature sensors, e.g. under the floor, control the impeller speed and the cooling means temperature so that the equipment temperature s maintained in the narrow range required for optimum func- ioning. If one unit should fail or be shut down for servicing the adjacent units can provide temporary back-up by opening of tampers (23) at each side of the affected unit and increased mpeller speed in the remaining units.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
An air conditioning system comprising at least two operative air supply units (10, 11, 12) each in the form of a housing (13) enclosing impeller means (14) operative to draw air into the housing (13) and cause same to flow through filter means (15) and cooling means (16), whereby it is rendered substantially free of contaminants and cooled, and out of the housing (13) via one or more ducts extending beneath floor level (20) to equipment, such as a computer, characterised in that the units (10, 11, 12) are arranged side by side with adjustable dampers (23) provided therebetween so that in the event of failure of one unit, the dampers (23) at one or both sides of that unit may be automatically opened to allow air from other units to supply the equipment connected to that unit until such time as it is repaired, and in that temperature sensors are provided to control the speed of operation of the respective impeller means (14) and/or the temperature of the respective cooling means (16).
Claim 2
Dependent Claim
173 words
An air conditioning system comprising at least two operative air supply units (10, 11, 12) each in the form of a housing (13) enclosing impeller means (14) operative to draw air into the housing (13) and cause same to flow through filter means (15) and cooling means (16), whereby it is rendered substantially free of contaminants and cooled, and out of the housing (13) via one or more ducts extending beneath floor level (20) to equipment, such as a computer, characterised in that the units (10, 11, 12) are arranged side by side with adjustable dampers (23) provided therebetween so that in the event of failure of one unit, the dampers (23) at one or both sides of that unit may be automatically opened to allow air from other units to supply the equipment connected to that unit until such time as it is repaired, and in that temperature sensors are provided to control the speed of operation of the respective impeller means (14) and/or the temperature of the respective cooling means (16).
Claim 3
Dependent Claim
42 words
An air conditioning system as claimed in claim 1 wherein each housing (13) includes a plenum chamber (21) beneath floor level (20) and air flows therefrom into the duct or ducts by way of a plate (22) having openings of variable area.
Claim 4
Dependent Claim
26 words
An air conditioning system as claimed in claim 2 wherein the dampers (23) are located between the plenum chambers (21) of adjacent units (10, 11, 12).
Claim 5
Dependent Claim
25 words
An air conditioning system as claimed in claim 1, 2 or 3 wherein each damper withdrawal mechanism is actuated by means of a temperature sensor.
Claim 6
Dependent Claim
26 words
An air conditioning system as claimed in claim 1, 2 or 3 wherein each damper withdrawal mechanism is actuated by means of an air flow sensor.
Claim 7
Dependent Claim
39 words
An air conditioning system as claimed in claim 5 when dependent on claim 2 or 3, wherein air flow sensors are located in each plenum chamber (21) and/or adjacent air outlets of the equipment being supplied with clean air,
Claim 8
Dependent Claim
33 words
An air conditioning system as claimed in claim 4 or 5 wherein the air flow sensors are capable of controlling the speed of operation of the impeller means (14) of the other units.
