摘　　要：为提高膜式全热换热器的换热效率,对换热器中流场施加高压电场,在相同的实验条件下,通过测量换热器的显热和潜热效率来分析外加高压电场对换热效果的影响,并且在此基础上,测试了不同电极电压、风速情况下换热器的换热效果。实验结果表明,在换热器流场中施加高压电场,能够有效地提高换热器的显热效率,对潜热效率的提高则不明显;在低风速的条件下,强化换热效果更加明显。To enhance the heat exchange efficiency of a membrane type full heat exchanger,a high voltage electric field was applied to the heat exchanger.Under the same test conditions,the influence of the electric field applied from outside on the heat exchange effectiveness was analyzed by measuring both sensible and latent heat efficiency of the exchanger.On this basis,the heat exchange effectiveness of the exchanger was tested at various voltages of electric poles and different wind speeds.The test results show th...
