The effectiveness of solar adsorption system for space conditioning would be enhanced through radiant ceiling cooling; since a higher chilled water temperature can be supplied. In such provision; desiccant dehumidification should be involved in order to cater for the latent cooling load. A solar hybrid adsorption refrigeration system is therefore formulated. In this study; the effect of radiative load ratio R of active chilled beams (ACB) and passive chilled beams (PCB) for the solar hybrid adsorption refrigeration system was investigated. Through the year-round dynamic simulation; it was found that the performances; like solar fraction and primary energy consumption; of the system with ACB or PCB would be improved along with the decrease of R from 0.3 to 0.1. At the same R; the system with PCB would have better performances than that with ACB. With suitable design and control; the solar hybrid adsorption refrigeration system with PCB at low R would be more technically feasible for office use in the subtropical climate.
