为了研究微小通道两相流换热规律、进行微小通道冷凝器蒸发器设计的验证及总结蒸发循环系统的控制规律和方法,设计并搭建了以R134a为工质的冷凝器蒸发器性能实验台。并对该实验台从原理到调试作了详细介绍,探讨了工质充注、测试方法及制冷量控制等技术问题,最后还进行了相关实验。 In order to study the heat transfer law of two-phase flow in microchannels, to verify the design of the micro-channel condenser evaporator and to summarize the control rules and methods of the evaporation cycle system, the experimental bench of condenser evaporator with R134a as the working fluid was designed and constructed. The test bench is introduced in detail from the principle to the debugging, and the technical problems such as working fluid filling, test method and cooling capacity control are discussed. Finally, relevant experiments are carried out.
