AI Technical Summary

Technical Problem

In existing technologies, outdoor heat exchanger contamination detection methods rely on fixed benchmark values ​​from laboratory calibration data, which leads to missed or false detections of air conditioners in different installation environments and conditions, and cannot adapt to changes in actual installation conditions.

Method used

By dynamically determining whether a detection benchmark value adapted to the current operating mode is stored when the air conditioner is powered on and running, if no benchmark value is stored, the operating status parameters of the sample are collected to calculate a unique benchmark value. The pollution determination is then made in combination with the actual configuration of the air conditioner and the on-site working conditions, avoiding reliance on uniform laboratory settings.

Benefits of technology

It improves the accuracy and reliability of outdoor heat exchanger contamination detection, adapts to different installation environments and conditions, and avoids misjudgment and missed detection.

Abstract

The embodiment of the application provides a kind of outdoor heat exchanger pollution detection method, device, air conditioner and storage medium, it is related to air conditioning control technical field.Under the condition that air conditioner is powered on and current operating environment parameter meets preset detection condition, it is determined whether the detection reference value corresponding to current operating mode is stored in air conditioner;If it is stored, the current operating state parameter of air conditioner is obtained, and whether the outdoor heat exchanger appears pollution is determined according to current operating state parameter and detection reference value;If the detection reference value corresponding to current operating mode is not stored in air conditioner, then a plurality of sample operating state parameters under current operating mode are collected, and the detection reference value corresponding to current operating mode is calculated based on a plurality of sample operating state parameters.In this way, both normal conditions can be avoided to be misjudged as pollution, and real pollution can also be prevented from being missed due to reference mismatch when it occurs, significantly improving the accuracy and reliability of outdoor heat exchanger pollution detection.
