Type of article: Article

Summary

Aiming at widely used ground-source heat pump systems, the authors present three operating control modes and establish an evaluation method based on the cylindrical source theory. Simulated results show that there exists an optimization problem between the underground thermal balance and running time of cooling towers. From the viewpoint of energy efficiency of cooling towers and underground thermal balance, they recommend the operating mode by setting the average water temperature of buried exchangers or by setting the difference between the water temperature of buried exchangers and the wet-bulb temperature of environment. The operating modes of the hybrid systems shall be determined based on the integration of different factors and the proper combination of the three modes is also allowed if necessary.
