The Operational Monitor of Air-Conditioners by Using Probabilistic Neural Network

This paper uses the probabilistic neural network (PNN) to monitor the operation statues for the compressor of air-conditioners. The field data including the high/low pressures and the high/low temperatures of refrigerants are measured in a practical system. PNN analyses the refrigerants’ pressures/temperatures of air-conditioners to monitor the operation conditions of compressor. PNN method is suitable for application in a dynamic environment by using new data-set and new hidden without doing any computed iteration. Computer simulations were conducted with refrigerants’ records, test results showed the effectiveness of the proposed system.
