Adsorption chiller technology is one of effective means to convert waste thermal energy into cooling, which substantially improves energy efficiency and lowers environmental pollution. This article develops an improved lumped-parameter model for multi-bed silica gel-water adsorption chillers. It is validated by experimental results stemming from a fourbed silica gel-water adsorption chiller at various operating conditions. It is found that the performance predictions from this model compare favourably with experimental results. At all tested conditions and over a wide range of cycle times, the cooling capacity and COP can be predicted to within 10% and 12%, respectively.
