浅层地热能+太阳能联合系统在冀南地区新农居中的应用

以河北省冀南地区某新农村住宅为研究对象,分析太阳能资源和浅层地热能资源的分布规律和特征,提出2种运行模式,进行了全年运行数据监测,从技术性和经济性等角度对联合系统和单一系统的运行效果进行综合对比分析。结果表明:联合系统的综合性能优于单一地源热泵系统,在冀南地区采用联合系统更高效节能。

Study on visualization simulation of temperature distributions in surrounding rock of tunnels in a deep mine

Based on the mathematical model for rock temperature distribution in a geo-thermal field,the properties of rock temperature distribution in geothermal field for fourkinds of surrounding rock cross-sections of tunnels in a deep mine were simulated by us-ing finite element method.It is shown that the relationship for rock temperature distributionvaried with the geothermal parameters,time and space.Namely, 2-dimensionaltime-dependent isograms clearly showed the process for rock temperature variation anddistribution in a geothermal field which has been redisplayed with visualization numericalsimulation.
