以地源热泵地埋管非稳态随机传热模型为研究对象,将地埋管周围土壤温度场的随机性作为研究的重点,利用数值解法中的有限差分法,对地源热泵地埋管二维非稳态随机传热模型建立了古典隐式格式的差分方程。从而能够求解出地埋管周围土壤温度场的数值解,为进一步分析非稳态随机传热模型的随机温度场打下基础。 Taking the random heat transfer model of ground source heat pump buried pipe as the research object, taking the randomness of soil temperature field around the buried pipe as the research focus, by using the finite difference method in numerical solution, Two-dimensional unsteady stochastic heat transfer model is established for the classical implicit difference equation. Which can solve the numerical solution of the soil temperature field around the buried pipe and lay the foundation for further analysis of the random temperature field of the unsteady stochastic heat transfer model.
