The research on the influence law of the fluid temperature in ground heat exchange on system operation

摘要

In the paper, by studying the underground heat exchanger heat transfer mode, the computing platform for ground source heat pump system was established. Through a engineering case, the influence character of the fluid temperature at the outlet of ground heat exchange on the length of system, the fluid temperature in ground heat exchange, and the heat pump power consumption were analyzed, which provide an approach for engineering design and operation prediction, and for the thermodynamic analysis of performance of system year by year and prospective study to guide the engineering practice.
