Abstract

A refrigeration system achieves its refrigeration function generally through cryogenic refrigerant generated by multiple refrigerant compressor units. Traditionally, the operation of refrigerant compressor units is controlled only by experience or the proportional-integral-derivative controller of refrigerant temperature or pressure. Due to the lack of scientific, systematic and optimum logic basis, it is difficult to optimize the operation of refrigeration system and control the excessive energy consumption with these methods. On this basis, this study employs the system optimization method to determine the optimum operation of each compressor unit within the system to obtain the most energy-saving operation for maximum operation efficiency of the refrigeration system (energy consumption efficiency), according to the actual required refrigeration capacity at load side, actual performance and operation condition of each unit. The results reflect that the system optimization method can obtain the optimum solution and increase the coefficient of performance of the original refrigeration system by 7.83%.
