Abstract:

Abstract：A large number of discarded freezing pipes were legacy after the construction of freezing method, which diameter were very wide, buried depth. The discarded freezing pipes can be used as the buried tube heat exchanger, which heat transfer were more than that traditional ground source heat pump heat exchanger , and even more realized waste utilization, greatly saves the project investment. Taking the practical as an example, this article introduces the use of freezing pipe for ground source heat pump heat exchanger heat pump system design method.

Key words: freezing pipe, ground source heat pump system, system design
