Liquid ammonia storage leakage accident occurred frequently in recent years. In this paper, the Infrared thermal imaging Technology had been presented by introducing the applications of liquid ammonia storage inspection. It was indicated that the infrared thermal imaging technology had irreplaceable advantages in equipment insulation condition assessment, funneled detection, heat level judgment, electrical equipment failure hidden. The experiments showed that infrared thermal imaging technology could provide scientific references for early diagnosis and preventive maintenance of devices. And it had widely application prospect in the ammonia refrigeration system safety inspections.
