Problems solved by technology

[0003] However, when the air conditioner breaks down and needs to replace the compressor, there is a problem of after-sales operation errors and the inverter is installed backwards. The above dialing method will not be able to detect such problems
[0004] At present, for the air conditioner problems caused by the reverse installation of the frequency converter, the user can only return the air conditioner to the factory for maintenance, which not only consumes time and manpower, but also affects the use of the air conditioner by the user

Abstract

The invention relates to a detection method and equipment for preventing reverse installation of an air conditioner frequency converter and an air conditioner. The method comprises the steps that the exhaust temperature and the outdoor environment temperature are subtracted to obtain a first difference value; and whether the frequency converter is reversely installed is judged according to a comparison result of the first difference value and a temperature threshold value. According to the scheme, the air conditioner can complete frequency converter fault self-detection and fault handling, even if a user cannot replace the frequency converter in time, normal operation of the air conditioner can be guaranteed through data correction in the air conditioner, the time and energy of the user are saved, and meanwhile, the requirement of the user for using the air conditioner is guaranteed preferentially.

Description

technical field [0001] The present application relates to the technical field of air conditioners, and in particular to a detection method, equipment and air conditioner for anti-reverse installation of frequency converters of air conditioners. Background technique [0002] With the improvement of people's quality of life, the demand for the capacity of current air-conditioning products is also increasing. In recent years, multi-connected heat pump air conditioners have developed rapidly, and are gradually accepted by people because of their space-saving, beautiful, and energy-saving features. Load adjustment capability output to achieve energy saving effect. In order to better enable the main control board to monitor the compressor data corresponding to the frequency converter, the dialing method is currently used on the frequency converter, and the main control board will monitor the operation of the corresponding compressor according to the dialing address of the frequen...
