本文将目前国际上广泛应用于长管道输送系统中的检测管道泄漏的实时模型法应用于液态氨制冷剂管路泄漏研究。并以R22制冷剂来模拟氨系统循环管路，根据动态及泄露实验研究特性，建立检漏、定位的实时模型，并通过实验验证了该模型可以实现高效快速的检漏效果及确定漏点位置，检漏精度可达到3.0％，但定位精度及稳定性与漏点位置有关。这为冷库的安全运行提供了有效措施和理论依据。

The real-time model which is widely used in the detection of long pipeline leakage is applied to detect ammonia leakage in the pipeline of refrigeration systems in cold stores. The pipeline of refrigeration system with R22 is used to simulate the ammonia system. The real-time model of leak detection and positioning is set up through the dynamic characteristics of refrigerant and testing results of leakage. The model is verified by experiments and the result shows that the accuracy of leak detection can reach 3. 0%, and the positioning preci-sion and stability is related to the position of leakage, which indicates that it can efficiently and rapidly achieve leak detection and deter-mine position of leakage. This research provides effective methods and theoretical basis for the safe operation of refrigeration system in cold stores.
