Abstract

The invention relates to a method and device for detecting dirty blockage of a heat exchanger, which includes collecting actual operating data during operation of the heat exchanger, and calculating theoretical operating state data according to the actual operating data and a predetermined operating state model; wherein, the operating The state model is determined according to the operating data and operating state data when the heat exchanger is not dirty and blocked; the actual operating state data corresponding to the actual operating data during the operation of the heat exchanger is obtained; according to the actual operating state data and theoretical operating state data, Determine if the heat exchanger is dirty. The invention can judge the degree of dirty blockage of the unit heat exchanger based on historical data, improves the judgment effect and detection speed, and solves the problems of excessive algorithm error and insufficient stability due to the small number of monitored operating parameters, and improves the efficiency of the heat exchanger. The accuracy of dirty blockage determination can also summarize the development trend through historical operation data and real-time operation data, so as to accurately predict the future dirty blockage of heat exchangers.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method and device for detecting dirty blockage of a heat exchanger. Background technique [0002] Under the influence of factors such as long-term use and water quality of the air conditioner, the pipes in the heat exchanger of the unit will easily become dirty and blocked, which will affect the heat exchange effect of the unit and lead to abnormal parameters of the air conditioner (such as an increase in the current of the main unit). The energy efficiency ratio is reduced, which affects the operation of the unit and the user experience of the customer. Therefore, it is necessary to monitor, detect and analyze the degree of dirty blockage of the air conditioner heat exchanger. [0003] In related technologies, the detection method for the degree of fouling and clogging of the air conditioner heat exchange device is mainly based on a single or a small number...
