Evaluation Study on a Novel Structure CCHP System with a New Comprehensive Index Using Improved ALO Algorithm

The CCHP system is a reasonable and effective method to improve the current situation of energy use. Capacity allocation great significance in improving performance system. Due particularity chemical enterprises’ production process, demand for cooling, heating, power load also relatively particular, which makes dynamic loads challenging be satisfied. Because above problems, structure typical improved, embodied collocation multi-stage lithium bromide chiller, use various storage devices. Based on improved ant lion intelligent optimization (ALO) algorithm, comprehensive evaluation index coupled with benefit, economic environmental taken as objective function, equipment capacity configuration enterprises studied. Considering winter, summer, transition seasons, results show that better than annual cost savings new structural are up 13%, carbon dioxide emissions reduced by 36.39%. primary utilization rate increased 18%, performs better. optimal can reach 0.814.
