| Abstract: | 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. |
