Abstract
Hybrid ground source heat pump systems tire applied in the cold winter and warm summer areas where the cooling load in summer is much more than heating load in winter, and a huge freedom exists in the control strategy. A new control strategy is proposed, by which the outlet water temperatures of the cooling tower and plate heat exchanger (PHE) coupled with ground heat exchanger (GHE)could be compared directly. The dynamic numerical simulation model of hybrid ground source heat pump system was constructed through sofrware FLUENT to getting the ANN datas,multi -models was con-struced by adopting three BP layer networks .Results show that ANN could realize the prediction exactly with the absolute error less than 0.4℃.关键词
