【摘要】 对高湿地区风冷热泵蒸发器结霜过程进行了理论分析及实验测试。研究表明 ,在高湿地区 ,霜层的形成及霜厚的增加较快 ,以蒸发温度及空气压降作为除霜控制参数是合理选择化霜周期的重要依据。更多还原

【Abstract】 The theoretical analysis and experimental measurements of frosting process of air-cooled heat pump evaporator in high humidity district are conducted. The results indicate that the formation and developing of frost are rapid in high humidity district. The evaporating temperature and the air pressure drop are the important parameters to the choice of the reasonable defrosting cycle.更多还原
