The study concerns the theoretical investigation of the performances of a fixed-bed adsorption dehumidifier, based on the results of a comprehensive testing campaign. By analyzing the batch operation of the system and fitting the experimental data related to different operating conditions, two semi-empirical formulas have been developed to accurately predict the dehumidification rate and the thermal COP of the prototype. Such formulas allow implementing different control strategies of the dehumidifier, prioritizing the saving of either electricity or thermal power. The approach we used in developing the equations may be usefully applied to other similar batch operated systems. © 2016 Elsevier Ltd

Abstract

The study concerns the theoretical investigation of the performances of a fixed-bed adsorption dehumidifier, based on the results of a comprehensive testing campaign. By analyzing the batch operation of the system and fitting the experimental data related to different operating conditions, two semi-empirical formulas have been developed to accurately predict the dehumidification rate and the thermal COP of the prototype. Such formulas allow implementing different control strategies of the dehumidifier, prioritizing the saving of either electricity or thermal power. The approach we used in developing the equations may be usefully applied to other similar batch operated systems. © 2016 Elsevier Ltd
