摘　　要：对以氯化钙 -氨为工质对的固体吸附式制冷系统单元管的外特性进行了系统的研究 ,建立了单元管的实验装置并进行了热力分析计算 ,得出了单位质量制冷剂制冷功率 ( SCP)以及性能系数 ( COP)随蒸发温度的变化曲线。结果表明 ,蒸发温度和冷凝温度在吸附循环过程中对单管性能影响较大 ,应合理加以匹配。Based on a conventional text rig for unit tube and thermal calculations, the performances and the outer properties of an adsorption refrigerating unit tube using CaCl 2 as adsorbent and NH 3 as refrigerant were investigated systematically. From the experiment data, the SCP and COP as the functions of the vaporizing temperature had been obtained and illustrated graphically. It is concluded that the evaporating and condensing temperature have effect on the performances of unit tube, and should be rational matching.
