1. A cooling system for cooling an enclosure, the cooling system comprising:
a heat exchange section configured to transfer sensible heat between an inlet air stream and a humid working air stream;
a humidifier located outside the heat exchange section and configured to humidify a working air stream, extracted from the inlet air stream, to generate the humid working air stream so that the humidifier transfers latent heat;
an air moving system configured to move various air streams through the cooling system; and
a piping system configured to provide the humid working air stream from the humidifier to the heat exchange section, and the working air stream to the humidifier,
wherein the sensible heat transfer between the inlet air stream and the humid working air stream is decoupled from the latent heat transfer at the working air stream.
