To solve the problem of the competition between the COP and SCP of the compressordriven adsorption refrigeration system, the multi-objective dynamic optimization model of this system has been presented. In this model, the volume flow rate and the cycle time are the control variables, and the COP and SCP attaining superior in the meantime is the objective function. Thus the multiple-objective optimal problem is converted into a simple objective optimization by using the linear weighting addition method and the maximum and minimum method. Based on the above, iterative dynamic programming algorithm is presented to solve the model, and the effectiveness of this algorithm is confirmed for solving this kind of model. Finally, the optimal cycle time and the volumetric flow rate control curve with time have been obtained under different weighting factors, and the optimal control of the compressor-driven adsorption refrigeration system has also been achieved under different working conditions.
