Fault handling method and device for air conditioner and air conditioner

Abstract

The invention provides a fault handling method and device for an air conditioner and the air conditioner. The fault handling method for the air conditioner includes the steps that whether a communication fault occurs between an indoor unit and an outdoor unit of the air conditioner is detected; when a communication fault between the indoor unit and the outdoor unit of the air conditioner is detected, the indoor unit and the outdoor unit are controlled to continue operating in the current operating mode; when the time length that the indoor unit and the outdoor unit are controlled to continue operating reaches a preset time length, if the communication fault between the indoor unit and the outdoor unit is not relieved, the indoor unit and the outdoor unit are controlled to stop working. By means of the technical scheme, it is guaranteed that the air conditioner system can continue operating for a period of time when a communication fault occurs between the indoor unit and the outdoor unit of the air conditioner, and serious economical loss caused by direct shutdown of the air conditioner system on some special use occasions is avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner fault handling method, an air conditioner fault handling device and an air conditioner. Background technique [0002] The air conditioner system generally consists of an outdoor unit, an indoor unit and a control panel (wire controller or remote control). Wherein, the indoor unit and the outdoor unit are connected through a shielded twisted pair to realize wired communication. Due to the complex installation environment, harsh use conditions and long continuous working hours of commercial air-conditioning equipment, communication failures between internal and external units often occur during the use of air conditioners, and communication failures between internal and external units are mainly caused by the following reasons: 1. Irregular installation, wiring Unreliable and damaged lines; 2. No dedicated shielded communication lines are used, ...

AI Technical Summary

Problems solved by technology

After the user sees the fault, he will contact the maintenance personnel for maintenance. That is to say, the air conditioner cannot be used until the communication failure of the air conditioner occurs and the repair is completed.

However, for some special occasions, such as farmers with high temperature and humidity requirements, computer rooms where important electronic equipment is installed, high-end commercial air-conditioning applications, etc., the shutdown of the air-conditioning system will cause huge economic loss

[0004] Therefore, how to avoid the direct shutdown of the air-conditioning system and cause economic losses when there is a communication failure between the indoor unit and the outdoor unit of the air-conditioner has become a technical problem to be solved urgently.
