Abstract

The invention relates to a heat exchanger filth blockage detection method and device. The method comprises the steps of collecting the actual operation data of a heat exchanger during operation, and obtaining the theoretical operation state data through calculation according to the actual operation data and a predetermined operation state model, wherein the operation state model is determined according to operation data and operation state data when the heat exchanger is not blocked by dirt; acquiring actual operation state data corresponding to the actual operation data when the heat exchanger operates; and according to the actual operation state data and the theoretical operation state data, determining whether filth blockage occurs to the heat exchanger. According to the method, the filth blockage degree of the unit heat exchanger can be judged based on historical data, the judgment effect and the detection speed are improved, the problems of too large algorithm error and insufficient stability caused by few monitored operating parameters are solved, the accuracy of filth blockage judgment of the heat exchanger is improved, and the development trend can be summarized through historical operation data and real-time operation data, so that the filth blockage condition of the heat exchanger in the future is accurately predicted.

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...
