Multi Objective Optimization Of Air Conditioning System For Vault Spent Nuclear Fuel Storage

Abstract:

The optimization of the air temperature conditioning of an interim Vault dry storage has been considered.

The objective functions of the optimization including the total exergy destruction of the system (thermodynamic function) and the total product component and energy cost of the system. Three optimized values of decision variables (condensing- and evaporating temperature, sub cooling- and super heating temperature, cooling tower water inlet- and outlet temperature) for a single objective thermodynamic optimized, a single objective economic optimized and a multi objective optimized are obtained. From the optimized values of decision variables, it could be obtained the equivalent cooling cost of 803.17 (Rp/kWh) for economic optimized, 832.78 (Rp/kWh) for thermodynamic optimized and 811.04 (Rp/kWh) for multi objective optimized. These values are better than the value in base case (847.69 (Rp/kWh)).

Keywords: multi objective optimization, genetic algorithm, exergy, chiller
