Abstract :
Effective diagnosis methods to improve the efficiency and accuracy of air-conditioning equipment maintenance work developed at NTT are described. These methods consist of the refrigerant cycle diagnosis of air-conditioners and the deterioration diagnosis of pumps and ventilators. These technologies reduce manpower requirements and improve the accuracy of maintenance work on air-conditioning systems
