摘要
《地源热泵系统工程技术规范》中推荐的垂直埋管换热器的理论算法中,提出了指数积分(Iu)。本文着重分析了(Iu)的近似解法,并给出实际计算范例。
Abstract : In the recommended heat transfer algorithm of GSHP vertical buried pipe system, (Technical code for groumd-source heat pump system) refered to an exponential integral I(u). This article analyzed the approximate solution of I( u ).And calculation example is further given.
