摘　　要：为解决空调蒸发器在特殊环境下的耐腐蚀性问题,通过分析无氧铜(TU2)与高磷铜(TP2)的物理特性与化学成分,试验对比无氧铜蒸发器与高磷铜蒸发器的制冷制热性能。结果表明,无氧铜的物理性质与高磷铜相似,其加工与焊接性能相同;无氧铜中的氧含量低,其耐腐蚀性较强;性能试验中,安装无氧铜蒸发器的机器能力、能效均高于高磷铜蒸发器。因此,无氧铜替换高磷铜在提高了铜管的耐腐蚀性的同时,其换热性能也较好,证明了无氧铜替换高磷铜的可行性。In order to solve the corrosion resistance problem of air conditioning evaporators in special environments,by analyzing the physical characteristics and chemical composition of oxygen free copper(TU2)and high phosphorus copper(TP2),and compares the refrigeration and heating performance of oxygen free copper evaporators and high phosphorus copper evaporators by experimental study.The results indicate that the physical properties of oxygen free copper are similar to those of high phosphorus copper,and its processing and welding properties are the same.The oxygen content in oxygen free copper is low,and its corrosion resistance is high.In the performance test,the machine installed with oxygen free copper evaporator has higher capacity and energy efficiency than high phosphorus copper evaporator.Therefore,replacing high phosphorus copper with oxygen free copper not only improves the corrosion resistance of copper pipes,but also has good heat transfer performance,proving the feasibility of replacing high phosphorus copper with oxygen free copper.
