Published: — with international search report (Art. 2 I (3)) (54) Title: WATER MANAGEMENT SYSTEM OF A DUAL-AIR DUAL-WATER EVAPORATIVE COOLING APPARATUS (57) : An apparatus (100) is disclosed, which comprises a fluid stor- 112 100 age device (104) for holding a volume of coolant; a cooling device (106) hav- ing a heat exchanger (108) and a first evaporative media (110) arranged in fluid communication with the fluid storage device, the cooling device configured to enable air to be passed therethrough; and a heat rejection device (112) having 114 I a second evaporative media (114) arranged in fluid communication with the fluid storage device and the heat exchanger. The apparatus is operable between at least first and second modes for lowering temperature of the air, in which 106 1 in the first mode, only the first evaporative media is operatively activated to use the coolant to cool the air to a first temperature, and in the second mode, the first and second evaporative media and the heat exchanger are collectively 108 I activated to use the coolant to cool the air to a second temperature being lower than the first temperature. 116b 104 FIG. la
