空気調和機の性能診断装置及び性能診断方法
Document Type and Number:
Japanese Patent JP6933564
Kind Code:
B2
Abstract:
A performance diagnosis device performs data collection of operation data of an air conditioner, and a model database indicates performance corresponding to each operating condition of the air conditioner. The device uses the operation data and the model database to obtain reference data that is a combination of a plurality of operating conditions and a reference value. A performance evaluation unit compares the reference data and evaluation data that is to be evaluated, and evaluates the performance of the air conditioner. A reference data update unit compares the reference data and the evaluation data when the operating conditions match with each other, and updates the reference data. As a result, the deterioration diagnosis technology can update unique reference values that reflect the dimensional errors of each device, differences in installation conditions, and differences in operating conditions to appropriate values with respect to the deterioration of the performance of air conditioners.
