二次热回收热管式空调系统
Secondary heat recovery heat pipe air conditioning system
摘要
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.关键词
