摘要
针对微通道蒸发器的换热性能,在结露条件下,分析了冷冻水进口温度、空气进口温度、空气流速大小等参数对空气出口温度、换热器换热系数、空气侧压降等实验结果的影响程度,研究发现:提高冷冻水进口温度,空气侧换热系数和压降有不同程度降低,而空气出口温度有所升高。
Based on the heat transfer performance of microchannel evaporator, the parameters such as chilled water inlet temperature, air inlet temperature and air flow velocity are analyzed, such as air outlet temperature, heat exchanger heat transfer coefficient, air pressure drop, etc. the degree of influence of the experimental results. Through the study found that ： to improve the chilled water inlet temperature, air side heat transfer coefficient and pressure drop to varying degrees, while the air outlet temperature has increased.
