Analysis and Regulation Potential Evaluation of Air Conditioning Power Load in Zhejiang Province

The sharp growth of air conditioning load has become one main cause of seasonal power shortages. In this study, the power load structures of air conditioners and their regulation potential have been investigated by big data analysis and thermodynamics models. The results show that the summer power load of air conditioners in Zhejiang is about 18% higher than that in winter. The air conditioning power load reduction rate is approximately 3-11% when its setting temperature increases by 1°C in the refrigeration mode or decreases by 1°C in the heating mode. The maximum theoretical adjustable air conditioning power load capacity is 7.3 million kW in summer and 2.9 million kW in winter.
