铝-氨热管换热器用于空调排风余热回收的研究

Study on aluminum-ammonium heat pipe heat exchanger used for heat recovery from exhausted air in air-conditioning

分析空调系统能量回收的特殊要求,试验研究冬季工况铝-氨热管换热器的性能及影响因素。结果表明,余热回收效率随新排风温差增大而升高,随风速的增大而降低。该换热器具有换热效果好、阻力小的特点,说明其在冬季空调余热回收是可行的,也是有效的。

Analyzes special requirements of heat recovery in air-conditioning system,studies performance and influence factors of one aluminum-ammonium heat pipe heat exchanger under winter condition by some experiments.The results show that the heat recovery efficiency increases with the increase of temperature difference between the fresh air and the exhaust one,and decreases with the increase of the wind velocity.Generally,the heat pipe heat exchanger has excellent efficiency and low pressure drop,which shows its great prospect in air-conditioning system for energy-saving.
