摘要：

提出一种二次热回收热管式空调系统，其利用热管换热器做到二次热回收，设计该系统并搭建实验台，通过理论计算和实验比较该系统与其他系统之间的差异。以合肥为例，从理论上分析了二次热回收热管式空调系统的冬、夏季能耗，通过对实验数据的分析得出本系统冬季新风风速在1.20～1.85 m·s^-1之间热回收率能达到10%～23.2%；夏季新风风速在1.20～2.0 m·s^-1，室内外温差在4.2～8.0℃时热回收率能达到35%～55%，并提供了0～7.4℃的再热温差，表明了这种新的中央空调系统具有独特节能优势。

Abstract:

A secondary heat recovery heat pipe air conditioning (AC) system which performed secondary heat transfer by heat pipe heat exchanger (HPHE) is proposed. Considering the difference between secondary heat recovery HPHE AC and others, this paper designed the HPHE and built the tester. This article used Hefei as a sample, analyzed the energy consumption of the system in winter and summer. According to the analysis of experimental data, when the winter fresh air wind velocity is 1.20—1.85 m·s^-1, the heat recovery rate reaches 10%—23.2%. As the summer fresh air velocity is 1.20—2.0 m·s^-1 and the air temperature difference between indoor and outdoor is 4.2—8.0℃, the heat recovery can reach 35%—55%. Meanwhile, the reheat temperature difference 0—7.4℃ is provided for air supply. The results indicate that secondary heat recovery HPHE AC system has a unique energy-saving advantage.
