Abstract
A method of providing cooling air for cooling data centre IT equipment, an evaporative humidifier and an air handling unit is disclosed. The method comprises operating an evaporative humidifier (201) to humidify air for supply as IT equipment cooling air, the evaporative humidifier preferably comprising a deformable wettable matrix (207). Preferably, the method comprises steps of wetting the deformable wettable matrix (207), passing air through the wetted matrix (207) thus producing humidified air, and expelling water from the wettable matrix (207) by subjecting the wettable matrix to compressive deformation. The evaporative humidifier (201) preferably comprises a compressible wettable matrix (207), a water reservoir (217), a pump (218) for supplying water from the reservoir (217) to the wettable matrix (207), a frame for supporting the compressible wettable matrix, and an actuator (211) for effecting a compressive force on the compressible wettable matrix (207) for the purpose of expelling water from the wettable matrix (207). The air handling unit preferably comprises an evaporative humidifier (201) as disclosed.
