摘要
对地源热泵垂直地埋管换热器影响因素的随机性进行了分析,根据随机性理论,运用蒙特卡罗随机模拟方法对地埋管换热器进行随机模拟.结合工程实例,运用蒙特卡罗随机模拟方法对地埋管换热器进行可靠性设计计算,得到不同钻孔长度下地埋管出口水温概率分布.夏季地埋管设计出口温度不保证概率为6.1%时,对应的钻孔长度为650m,这与确定性条件下计算出的734m的钻孔长度相比,减小了11.4%.说明这种可靠性设计方法对缩短钻孔长度、减小工程初投资有重要意义.
According to the theory of randomness, this paper analyzes randomness factors of GSHP vertical ground heat exchanger with a simulation to ground heat exchanger in the method of Monte Carlo. In combination with an engineering examples, it makes a reliability calculation to ground heat exchanger with the method of Monte Carlo, and gets probability distribution in different drill pipe length about outlet water temperature. The failure proba- bility of design outlet temperature is 6.1 % during summer, with 650 m drilling length, and reduces 11.4% compared to the result under conditions of uncertainty. This reliability design methods is important to shortening the length of the borehole and reducing the initial invest- ment project.
