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 present application relates to a detection method, equipment and air conditioner for anti-reverse installation of an air conditioner frequency converter. The method includes: making a difference between the exhaust gas temperature and the outdoor ambient temperature to obtain a first difference; and judging whether the inverter is installed reversely according to a comparison result between the first difference and a temperature threshold. The solution provided by this application can complete the inverter fault self-inspection and fault handling by the air conditioner itself. Even if the user cannot replace the inverter in time, the internal data correction of the air conditioner can be used to ensure the normal operation of the air conditioner, which saves the user's time and energy. Guarantee the needs of users to use air conditioners.

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...
