地埋换热器温度场数值模拟及试验研究
Numerical Simulation and Experimental Research on the Temperature Field around Ground-loop Heat Exchangers
摘要
Abstract
The recovery characteristic of soil temperature field is an important basis to determine the long-term stable operation of GCHP.Explore the design methods of GCHP of a residential district,and introduce burying way of the main part soil heat ex-changer.The high-rise residence buildings’model is established and the annual air-conditioning load is simulated through the building thermal environment simulation software DeST-h.The large-scale commercial software FLUENT is used to simulate and analyze the soil temperature distribution and recovery around the ground-loop heat exchanger after a summer’s operation and a autumn’s recovery of GCHP.The temperature distribution of different strata during cooling process and recovery process of forma-tion temperature after cooling is studied experimentally.The results are in agreement with the numerical simulation.At last,the re-sult shows that hybrid GCHP is conducive to the restoration of the soil temperature,so that the system can run stably for a long time.关键词
