摘　　要：为减小乙二醇水溶液作载冷剂的间接制冷系统功耗,提升系统性能,达到节能目的,探讨选用密度小、比热容大、黏度小以及传热性能好的氨水溶液代替乙二醇水溶液使用,结合工程实例对间接制冷系统用氨水溶液的节能潜力进行分析。结果表明:氨水溶液作载冷剂可使COP最高提升9.77%,系统总耗功比原来减少3.32%~8.90%,年耗电量能节省至8.90%。总体来看,氨水溶液具有较大的节能潜力和经济效益,可以切实提升间接制冷系统性能,且氨水溶液性质稳定,安全可控,具有较大的应用前景。In order to reduce the power consumption of the indirect refrigeration system using glycol aqueous solution as the refrigerant, improve system performance, and achieve the purpose of energy saving, we explored the use of ammonia solution with low density, large specific heat capacity, low viscosity and good heat transfer performance instead of glycol aqueous solution.Analyze the energy-saving potential of ammonia solution used in indirect refrigeration system based on engineering examples.The results show that the ammonia solution as the refrigerant carrier can increase the COP by up to 9.77%, reduce the total power consumption of the system by 3.32%~8.90%, and save the annual power consumption to 8.90%. On the whole, the ammonia solution has great energy-saving potential and economic benefits, which can effectively improve the performance of the indirect refrigeration system, and the ammonia solution has stable properties, safety and controllability, and has a larger application prospect.
