夏热冬冷地区地源热泵系统冷热不平衡特性及优化运行策略研究
Study on the cooling and heating imbalance characteristics and optimal operation strategy of ground source heat pump system in hot summer and cold winter regions
摘要
Abstract
In order to reveal the thermal imbalance characteristics of the ground source heat pump system in hot summer and cold winter areas,this paper obtains the performance parameters of the system through numerical simulation over 10-years period of continuous opera-tion.Subsequently,a multi-objective optimization genetic algorithm was employed to integrate the system energy efficiency,thermal imbalance indicator underground and the source/end load imbalance rate,thus obtaining the optimal operating conditions.The findings indicate that during a single cooling or heating season,the borehole heat exchangers experience considerable heat and cold accumulation,accompanied by a gradual decline in heat transfer performance and a notable imbalance between the source and end load.Through optimal control,energy efficiency of the system is markedly enhanced.Furthermore,the thermal imbalance condition underground is improved.Additionally,the equipment of the composite geothermal heat pump system can be switched on and off adaptively,and the imbalance rate between the source/end load can be controlled to be less than 25%,thereby achieving on-demand cooling or heating supply.The findings of this study have the potential to promote the application of ground source heat pump in hot summer and cold winter regions.关键词
