Abstract

An economical and efficient air conditioning system for supplying clean air to equipment, such as a main frame com­ puter, comprises a row of units (10, 11, 12) arranged side by side. Each unit (1) has an impeller (14) which draws air in through a filter (15) and forces it through cooling means (16) to 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 is maintained in the narrow range required for optimum func­ tioning. If one unit should fail or be shut down for servicing the adjacent units can provide temporary back-up by opening of dampers (23) at each side of the affected unit and increased impeller speed in the remaining units.
