摘要
根据板式换热器的特点 ,结合低温工况下传热和流动阻力计算结果 ,提出了板式换热器作为低温蒸发器应用需要解决的一些技术难点 ,并通过试验分析 ,证实了其应用的合理性。
According to the properties of plate heat exchanger and its calculating results of heat transfer and pressure drop in low temperature condition, a plate heat exchanger was used as evaporator for the two circuit cascade system. It is well to be cautious and conservative when selecting plate heat exchanger for low temperature refrigeration. Application of plate evaporator was found to be reasonable by means of analysis testing results.
