1. A dehumidifying apparatus, comprising:
a first air distribution assembly connected to a process air inlet for receiving process air from the process air inlet, and to a regeneration air outlet for exhausting regeneration air via a vacuum unit; a second air distribution assembly connected to a process air outlet for delivering process air to the process air outlet, and to a regeneration air inlet for receiving regeneration air; at least three stationary modules connected in parallel between the first air distribution assembly and the second air distribution assembly; each module containing a desiccant and having a first aperture for connecting to the first air distribution assembly, and an opposite second aperture for connecting to the second air distribution assembly; a heater associated with each of said at least three stationary modules; the first and second air distribution assemblies configured to cycle between a number of discrete positions equal to the number of modules; in each position, the first and second air distribution assemblies configured to establish:
a regeneration air flow from the regeneration air inlet to the regeneration air outlet via said heater and, in sequence: the second air distribution assembly, the second aperture of one module, the first aperture of the one module, and the first air distribution assembly; anda plurality of process air flows from the process air inlet to the process air outlet via, in sequence: the first air distribution assembly, the first aperture of each remaining module, the second aperture of each remaining module, and the second air distribution assembly. |
