Apparatus And Method For Control Of Solid Desiccant Dehumidifiers

Abstract: The present invention relates generally to desiccant dehumidifiers. In particular, the present invention relates to solid desiccant dehumidifiers which use a rotor (commonly called a wheel) to dehumidify a process airstream. Dehumidification is a process of removing moisture from air. There are several known methods of dehumidifying air. However, two commonly used methods use refrigeration and desiccants. In the refrigeration based dehumidification method, moisture is made to condense over a cooling coil, thereby removing moisture from an air stream passing over the cooling coil. In the desiccant based dehumidification, the process employed is one of absorption or adsorption. In absorption, either liquid or solid desiccants are used, whereas for adsorption, solid desiccants like silica gel, activate alumna, molecular sieve etc. are used.
