Abstract
对螺旋扁管干式蒸发器(TDE)和常规折流板干式蒸发器(BDE)的传热性能进行实验研究。研究了蒸发温度(Te)、冷凝温度(Tc)、管外壳程流体Reynolds数(Reo)和热通量(qi)对传热性能的影响。研究表明,随着Te、Reo和qi的增大,TDE和BDE的传热性能均提高。随着Tc的增大,TDE和BDE的传热性能降低。对装配TDE和BDE的风冷热泵分别进行了测试,测试表明,在相同制冷工况下,TDE的总传热系数比BDE提高了36.3%,风冷热泵的制冷性能系数(COP)相应地提高了6.0%;在相同制热工况下,TDE的总传热系数比BDE提高了41.7%,风冷热泵的制热COP值相应地提高了15.8%;说明TDE可应用于风冷热泵,且其性能优于BDE
