【摘要】 针对目前制冷系统大部分时间都在部分负荷状态下工作和板式蒸发器换热性能研究较少的这些情况,本文对部分负荷下板式蒸发器的换热系数进行了研究。通过实验和计算,得出了低流速下板式蒸发器换热系数、制冷剂侧换热系数随水流速的变化关系,为板式蒸发器的设计和选型提供了参考。更多还原

【Abstract】 The refrigeration systems are working under partial load at present and there is scarcity investigation on the heat transfer coefficient of the plate evaporator,but few people notice them.In this paper heat transfer performance of the plate evaporator under partial load was studied some experiments and calculations were made.The relationships between heat transfer coefficient of the plate evaporator heat transfer coefficient of refrigerant side and the water flow velocity under low flow velocity were obtained,which gave some reference for design and chosen of the plat evaporator.更多还原
