A regression analysis wae conducted on experimental data obtained during the testing of a solid desiccant dehumidifier (Bharathan et a1.) at the Solar Enerav Research Institute (SERI has since been renamed the National Renewable Energy Laborstory). The data obtained was studied using statietical techiiquee to determine the regression equation for the temperature and humidity at the processed air outlet of the dehumidifier. These variables determine the cooling capacity and efficiency (Coefficient of Performance) of any deeiccant cooling cycle. The analysis ie uaed to determine therelative Impact the input parametere have on the outlet temperature and humidity.
