초록 ▼

A desiccant air conditioning system incorporates a desiccant material structure in the form of a heat exchanging desiccant bed. The heat exchanging desiccant bed is formed by granular desiccant material defining air passageways and liquid circulating channels for circulating heat transfer liquid in heat exchange relationship with the desiccant bed. The desiccant bed may include at least one stack of substantially parallel spaced-apart thermally conducting fins or plates with the granular desiccant material intimately bonded to the surfaces of the plates. The plates are provided by tube sheets or tube fins which include the tubes or channels for circulating heat transfer fluid. The method of air conditioning contemplates drawing building air to be conditioned through an adsorb air passageway; preconditioning the air by initially moisturizing or humidifying the air to substantially 100% relative humidity and adding heat to the moisture-laden air extracted from the air exiting from the desiccant bed. The preconditioned air enhances the ability to export or remove net latent heat and sensible heat energy from the system for better independent control of temperature and humidity. The preconditioned air passes through the heat exchanging desiccant bed for adsorption and condensation of excess water. At the same time cooling liquid circulating through the circulating channels of the desiccant bed exports and removes latent heat of condensation liberated by adsorption on the desiccant surfaces. A final step of evaporative chilling of the dried and cooled air brings the air condition parameters within the desired comfort zone range.

An improved desiccant air conditioning system comprising: a heat exchanging desiccant bed comprising desiccant material surfaces defining air passageways through the bed for contacting air in an air flow established through the air passageways with the desiccant material surfaces, and heat transfer liquid circulating channels in heat exchange relationship with the desiccant bed for removing heat energy from the desiccant bed and for adding heat energy too the desiccant bed; said desiccant bed comprising parallel plates having heat conducting surfaces and porous desiccant material granules in the granular size range of approximately 1/32 to ¼inch (0.08 to 0.65 cm) in diameter, intimately bonded to the heat conducting surfaces by an adhesive bonding layer, with the major portion of said granules being exposed for contacting air in the air passageways; moisturizing means operatively positioned upstream from the desiccant bed in the air flow of air to be conditioned for moisturizing and cooling air to be conditioned to substantially 100% relative humidity before entering the air passageways of the desiccant bed for enhanced and more efficient utilization of the desiccant bed in conditioning and cooling the air.
