AI Technical Summary

Technical Problem

Existing technologies make it difficult to monitor the compressor status during driver testing, which can lead to compressors easily reversing or running out of control, resulting in defective products reaching customers and potentially becoming unusable and scrapped.

Method used

By using a high-pressure pipe temperature sensor and a current transformer in the compressor protection system, combined with an EEV controller for real-time monitoring, it can be determined whether the compressor is reversing, and an early warning can be issued through a phase sequence alarm and a shell temperature over-limit alarm.

Benefits of technology

It enables real-time monitoring and early warning of anomalies in compressors, improves the quality control of tested products, prevents compressor damage, and meets the unified load testing requirements of multiple models and power ratings.

Abstract

The application belongs to the technical field of air conditioners, and discloses a compressor protection method and device, a compressor protection system and a storage medium. The method comprises the following steps: when it is detected that the test of the measured driver starts, a temperature signal of the high-pressure pipe temperature sensor is read after a preset time; a high-temperature pipe temperature value is determined according to the temperature signal; and it is determined whether to give a warning according to the high-temperature pipe temperature value and the operation mode of the compressor. In the above manner, when the test of the driver is performed, whether the compressor is reversed is determined by detecting the temperature value of the high-pressure pipe, so that whether the measured driver has a problem or whether the test wiring has a problem is determined, real-time monitoring and abnormal warning in the test process are accurately realized, the product quality control of the test is improved, and the compressor is prevented from being damaged. The compressor can be independent of the air conditioner system, meets the test requirements of unified load of multiple models and multiple powers.
