Abstract
The peak load regulation capacity of the phase change wall is simulated and analyzed by using TRNSYS software.Taking the library of a certain university in Hunan as the research object,the heat transfer model of the phase change wall is constructed and verified.Through simulation analysis of the operation effect under different pre-cooling parameters,the influence of electricity price structure and climatic conditions on the load regulation capacity of the phase change wall is evaluated.The results show that compared with the benchmark strategy,the scheme of pre-cooling at 23℃for 3 h can achieve a peak shaving effect of 46.64%and the cumulative electricity consumption throughout the day decreased by 4.94%.The greater the peak-valley price difference ratio,the stronger the economic efficiency of the pre-cooling strategy.This strategy has good applicability in hot summer and warm winter regions,but its energy-saving effect is relatively limited in mild or severe cold climate zones.The research results can provide references for the operation optimization and regional promotion of phase change walls.关键词
