Abstract

The invention discloses an emergency control method and device for an outdoor unit. The emergency control method and device for the outdoor unit is used for a multi-split air conditioner system. The emergency control method comprises the steps that state information of a first temperature sensor in the outdoor unit is collected; whether the first temperature sensor is in an abnormal state or not is judged according to the state information; when the situation that the first temperature sensor is in the abnormal state is judged, and second temperature information of a second temperature sensorin a candidate outdoor unit is utilized for correcting first temperature information of the first temperature sensor to maintain continue running of the multi-split air conditioner system; and the candidate outdoor unit is the outdoor unit with the second temperature sensor being not in the abnormal state in the multi-split air conditioner system. According to the emergency control method for theoutdoor unit, when the first temperature sensor in the multi-split air conditioner system is broken down, the temperature information of the second temperature sensor in the outdoor unit being not inthe abnormal state is utilized for correcting the first temperature information of the first temperature sensor, so that dynamic maintenance to the outdoor unit is achieved, and normal running of themulti-split air conditioner system is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an emergency control method and device for an outdoor unit. Background technique [0002] In air conditioning systems, temperature sensors are widely used. For example, common temperature sensors include: return air temperature sensor, coil temperature sensor, fresh air supply air temperature sensor, outdoor unit ambient temperature sensor, compressor temperature sensor, etc. . Since there are many application occasions of the temperature sensor, the failure probability of the temperature sensor also increases accordingly. Common temperature sensor failures include: temperature sensor short circuit, open circuit, temperature drift, etc. [0003] In the prior art, when a temperature sensor fails, the corresponding temperature sensor failure is reported for the failed air conditioner through the control logic. The faulty air conditioner cannot be turned on again until t...
