摘要：
A heat pipe air conditioning (AC) system which used heat pipe heat exchanger (HPHE) to realize secondary heat recovery was proposed. With the meteorological parameter of Hefei city (31 degrees 53'N and 117 degrees 15'6) as the reference, we analyzed the consuming energy between secondary heat recovery HPHE AC system and the common heat recovery HPHE AC system theoretically. The analysis of experimental data revealed that the average heat recovery efficiency of the HPHE AC system in winter is 21.08%, while 39.2% in summer. The results show that the secondary heat recovery HPHEAC system has a certain energy-saving advantage. (C) 2016 Elsevier B.V. All rights reserved.
