<p>A solid desiccant cooling system includes, means (13, 17) defining a first pathway (11) for air to be cooled and a second pathway (15) for regeneration air, and structure (14) retaining a mass of solid desiccant for cyclic movement between a first location (14a), in which the solid desiccant lies in the first pathway for dehumidifying the air to be cooled by adsorption of moisture to the desiccant, and a second location (14b) in which the solid desiccant lies in the second pathway for the regeneration air to take up moisture therein as water vapour. An air heater arrangement (40) is provided in the second pathway upstream of the second location for heating the regeneration air, and an air cooler arrangement (18), independent of the air heater arrangement, is provided in the first pathway downstream of the first location. An air delivery device (50) is coupled to both pathways whereby the device is operable to deliver air along both pathways from a common intake, wherein the pressure drop along the respective pathways is of a similar magnitude. Also disclosed are a method of operating a solid desiccant cooling cycle, and a control system for a solid desiccant cooling system.</p> |
