摘要
在所建立的内热源型埋地换热器模型基础上,采用专业多孔介质计算软件Autough2对模型进行模拟计算。在对单根换热器不同土壤物性对土壤温度影响模拟结果基础上,着重对U型垂直埋管换热器管群模拟只有取热或只有排热单季运行工况下的土壤温度变化,和既有取热又有排热的双季运行工况下的土壤温度变化,分析各自对地源热泵应用效果的影响。
Based on the inner heat source model of U-pipe underground heat exchanger, the numerical simulation study on the ground temperature field around U-pipe underground heat exchanger is carried out by using computer code of Autough2 in this paper. With the simulation results of influence of different soil property to the ground temperature field around the single U-pipe underground exchanger, the paper emphasizes the simulation and analysis of a group of U-pipe underground exchangers in a real project under two operation modes. One is the single-season operation mode, which only extracts heat from soil in a heating season or emits heat to soil in a cooling season in one year. The other is the double-season operation mode, which extracts heat from soil in the heating season and emits heat to soil in the cooling season in the same year. The effects of each condition on the ground coupled heat pump (GCHP) are analyzed and some general conclusions have been drawn.
