本文介绍了一个用于检测和诊断20千瓦（kW）微波发射机热交换器故障的实时专家系统。专家系统通过快速识别问题并推荐适当的解决方案，或预测尚未发生的迫在眉睫的问题来提高操作员的生产力。换热器专家系统已经过测试和调试。讨论了专家系统在供暖、空调和通风问题上的应用和扩展。引用:研讨会，ASHRAE Trans。，第95卷，第。2.

This article describes a real-time expert system for detecting and diagnosing faults in a 20-kilowatt (kW) microwave transmitter heat exchanger. Expert systems enhance operator productivity by quickly identifying problems and recommending appropriate solutions, or predicting impending problems that have not yet occurred. The heat exchanger expert system has been tested and debugged. Applications and extensions of the expert system to heating, air-conditioning, and ventilating problems are discussed.
