Abstract

La présente invention concerne un procédé et un système de prérefroidissement simple pour prérefroidir de l'air. Le système de prérefroidissement comprend un moyen de refroidissement sensible de premier étage permettant un échange de chaleur sensible indirect entre l'eau et l'air, afin de refroidir l'air et d'augmenter la température de l'eau et un moyen de refroidissement adiabatique de second étage permettant de refroidir l'air de façon adiabatique par un contact direct de l'eau avec l'air sous-refroidi par le moyen de refroidissement sensible de premier étage. Dans le procédé de prérefroidissement de l'air, l'air atmosphérique et l'eau sont mis en contact indirect pour un échange de chaleur sensible afin de refroidir l'air et de chauffer l'eau, et l'eau et l'air refroidi sont mis en contact direct pour un refroidissement adiabatique de l'air refroidi et de l'eau, l'air et l'eau étant refroidis de manière à atteindre une température de bulbe humide inférieure à une température de bulbe humide ambiante, par l'évaporation d'une quantité d'eau inférieure.
