AI Technical Summary

Technical Problem

When using combustible refrigerant in air conditioners in prior art, it is impossible to effectively distinguish the location of leakage, and it is impossible to actively identify refrigerant leakage. Sensor detection can only detect large flow leakage, and small leakage cannot be detected.

Method used

An air conditioner safety control device is designed, by installing multiple combustible refrigerant sensors in different locations inside the air conditioner, obtaining environmental data, determining whether the refrigerant leaks and/or leakage occurs, and controlling the operating status of the air conditioner based on the judgment results.

Benefits of technology

It realizes effective distinction between leakage locations in the air conditioner, and can actively identify refrigerant leakage, improving the safety and long-term reliability of the air conditioner.

Abstract

The invention relates to the technical field of intelligent air conditioners, in particular to an air conditioner safety control device, method and system, an air conditioner and electronic equipment. The combustible refrigerant sensors are installed at different positions in the cabinet air conditioner, the leakage position can be distinguished when refrigerant leakage occurs, alarm information including the leakage position is sent to a user, corresponding safety measures are taken, and the safety of the air conditioner is ensured. After an air conditioner is shut down and refrigerant migration reaches a stable state, the leakage identification system cuts off indoor and outdoor refrigerant connection through a safety valve, calculates the quantity of indoor side refrigerant substances through temperature and pressure parameters, judges whether leakage exists or not, sends leakage-containing alarm information to a user and takes safety measures. The leakage position of the cabinet is effectively distinguished when refrigerant leakage occurs, indoor pipeline leakage is recognized after the air conditioner stops, different alarm information about the leakage position or leakage is sent to a user, corresponding safety measures are taken, and the safety and long-term reliability of the air conditioner are guaranteed.
