Research on the development of a solar operated cross-cooled desiccant cooling system is described. A 15 cm x 15 cm x 15 cm (6'' x 6'' x 6'') cross-cooled silica gel desiccant dehumidifier model was designed, built and tested. The process of producing the silica gel sheets, the design and construction of the unit, the test setup and the test procedures are described in detail. A total of twenty tests were performed to determine the effect of inlet process stream dew point, process stream and cooling stream flowrates and regeneration stream temperature and dew point, on the performance of the unit. The test results show that the unit performance improves with increasing regeneration temperature, process stream flowrate and process air inlet dew point. The unit performance decreases with increase of the regeneration stream dew point. The results clearly show that the process stream inlet dew point is the dominating factor and that the concept of cross-cooling works very well. With moderate cross-cooling, the unit performance can increase over 50%. All tests were simulated by a computer program. The experimental and theoretical results are in very good agreement.
