In the sorption process, the removal of moisture from the air results in a release of heat (heat of sorption) that raises the air temperature as the process converts latent cooling load to sensible cooling load. Figure 39-4 shows three sensible cooling options that can be incorporated in desiccant systems to provide sensible cooling. The recuperative heat exchanger transfers heat to the air used to regenerate the desiccant. This can be supplemented by or replaced with a conventional chiller. The direct evaporative cooler evaporates water into the warm, dry air to cool it. Usually, this process cannot provide the full measure of required sensible cooling. The indirect evaporative cooler evaporatively cools a separate airstream and uses it to cool the dry air through an air-to-air heat exchanger.
