Modular solid desiccant system for dedicated outdoor air system units

Abstract

A modular unit is provided and includes a housing defining first and second interiors, first and second desiccant-coated heat exchanger assemblies disposed in the first and second interiors, respectively, an airflow system and a thermal system. The airflow system operates in and switches between first and second modes in which air moves through the first and second desiccant-coated heat exchanger assemblies in different directions, respectively, for dehumidifying the air in one of the first and second interiors and rejecting humidified air from another one of the first and second interiors. The thermal system is configured to thermally facilitate dehumidification in the one of the first and second interiors and to apply regenerating heat to the one of the first and second desiccant-coated heat exchanger assemblies in the another one of the first and second interiors.
