摘要(Abstract):
以汽车空调中使用的管带式冷凝器和蒸发器作为研究对象,试验测定了用HFC134a替代CFC12后换热性能变化。试验结果表明,在同样换热面积和换热量条件下,可以提高蒸发温度,降低冷凝温度,并减少制冷剂使用量。
The thermal performance of the heatexchangers used in automobile A/C systemwhich is due to the substitution of CFC12with HFC134a are studied. The test resultsshow that the evaporating temperature couldbe raised, the condensing temperature belowered and the refrigerant consumptioncould be saved, under the restriction ofheat transfer area and heat delivery requirement.
