Research on Coil Type Ice Storage Air Conditioning Technology for Power Grid Peak Regulation
Energy storage is a key technology that contributes significantly to achieving the strategic goal of carbon peaking and carbon neutrality.At present,the contradiction between power supply and demand has become increasingly acute with the high proportion of renewable energy access and the rapid growth of power demand.This problem is particularly prominent during the peak power consumption in summer.The ice storage air conditioning system uses valley electricity to make ice during nighttime,thereby storing cold energy.and it melts this ice for cooling during peak power consumption in the daytime,which is conducive to peak load regulation of power grid and improvement of energy economy.This paper summarizes and analyzes the research status and development direction of the key technologies of coil type ice storage air conditioning.At the system control level,various optimal operation strategies of ice storage air conditioning system are compared and analyzed.On the aspect of ice storage and melting mode,the characteristics of three modes of internal melting,external melting and combination of internal and external melting are described in detail,and the energy model is summarized.At the structural level,the influence of the enhanced heat transfer method on the heat transfer performance is analyzed.Finally,the research results and application prospects of coils with different materials are summarized.
