Refrigerant leakage detection and diagnosis for a distributed refrigeration system

A new method developed for automatic detection of refrigerant leakage in distributed refrigeration system, is presented in this paper. A supermarket store in Colorado was used as a prototype for the design of the system model and the testing and evaluating of the detection and diagnostic technique. The developed techniqueis able to detect a leakagewhen the refrigeration system loses more than 1% of the initial charge.
