摘要

The objective of this work is to model initially,the different components of a single-bed adsorption system with intermittent cold production operating with hot water coming from either biogas(from methanation of animal organic waste),or a flat sensor.Then,in a second step,to the Simulink resolution to determine the evolutions of the desorption temperatures for the two working couples(Thmax of 180°C and 220°C),of the adsorbed fraction(6 kg/s for the zeolite water and 4 kg/s for silica gel-water),COP(coefficient of refrigeration performance)of the order of 0.34 for silica gel-water and 0.4 for zeolite-water.These results were compared to those found in the literature for validation.It should be noted that the heat transfer fluid used is water,which has a cold production range between 0℃and 10℃(cooling applications)and that modeling uses the Dormand-Price OD45 method.
