Process to reduce the temperature of a feed of air by (a) contacting the feed of air with liquid water wherein part of the water evaporates to obtain air with a higher humidity and a reduced temperature. The air obtained in step (a) is contacted in step (b) with an aqueous hygroscopic solution to obtain air with a reduced humidity. In a step (c) the air obtained in step (b) is contacted with liquid water wherein part of the water evaporates to obtain air with a reduced temperature as compared to the air obtained in step (a). In a step (d) the water diluted hygroscopic solution obtained in step (b) is concentrated and cooled to obtained a concentrated and cooled hygroscopic solution which solution is used as the aqueous hygroscopic solution or as part of the aqueous hygroscopic solution in step (b).
