问题 单项选择题

某地埋管地源热泵系统需要进行岩土热响应实验,正确的做法是下列何项?()

A.应采用向土壤放热的方法进行实验

B.应采用向土壤吸热的方法进行实验

C.按照设计图对全部地埋管井做热响应实验

D.应采用向土壤放热和自土壤吸热的两种方法进行实验

答案

参考答案:A

解析:

根据《地源热泵系统工程技术规范》GB 50366—2009附录C可以明确得出,热响应实验是采用电加热器向土壤连续放热的方法进行实验(亦可参见第2.0.25条的术语解释),由此可知选项A是正确的(但在实际工作中,也有土壤吸热的方法,但不必两种方式都要同时进行,考试应以规范为准,由此选项D是错误的)。
