Economic optimization of energy efficiency reconstruction of cool storage air conditioning for existing buildings

Analyses the energy consumption and energy efficiency potential of existing buildings in China. To alleviate the electricity peak-valley difference, proposes transforming the cold source into that with cool storage without changing the water chiller for the existing buildings. Establishes the optimal design mathematical model to find the most economic cool storage rate,  obtains the best transformation plan for an example building with the model, and verifies its economical efficiency and feasibility.
