The idea of solving muhi-objective optimization is expounded with the method of Genetic Al- gorithm（GA） based on the introduction of the characteristics of capillary radiation air-conditioning system. With the model of the capillary hydraulic calculation, the hydraulic calculation of the system is transformed into solving Pareto optimal solution of multi-objective optimization problems with GA. The advantages and disadvantages are analyzed and compared of the weight coefficient transformation method, parallel selection method, order selection method, sharing function method and hybrid meth- od of solving multi-objective optimization problem in hydraulic calculation model, and then the appro- priate method is selected. It provides a theoretical basis for the hydraulic calculation of capillary radia- tion air-conditioning system.
