【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]:This paper presents a secondary heat recovery heat pipe air conditioning system. The heat pipe heat exchanger is used to achieve secondary heat recovery. The system is designed and the experimental platform is built. The differences between the system and other systems are compared by theoretical calculation and experiment. Taking Hefei as an example, the energy consumption in winter and summer of secondary heat recovery heat pipe air conditioning system is analyzed theoretically. Through the analysis of the experimental data, it is concluded that the thermal recovery rate of the winter fresh wind velocity of this system can reach 10 ~ 23.2 in the range of 1.20 ~ (1.85) m s ~ (-1). When the wind speed of the summer fresh wind is 1.20 ~ (-2) m s ~ (-1) and the indoor and outdoor temperature difference is 4.2 鈩，
