Optimization of cold and heat source for a small energy station in Chongqing

Simulates the hourly load of a small energy station in Chongqing by the TRNSYS software, obtains the hourly load and load ratio, and analyses the load characteristics of the buildings. According to the load ratio distribution, performs the optimal design for the energy station by the objective function of annual operating cost and life cycle cost (LCC). The result shows that the LCC of the centrifugal liquid chiller and direct-fired absorption chiller is less.
