Air conditioning unit and control method thereof

Abstract

The invention provides an air conditioning unit and a control method thereof, particularly relates to the technical field of air conditioners and is used for automatically determining whether an electricity meter of the air conditioning unit deviates or not. The air conditioning unit comprises a photovoltaic panel used for converting collected solar energy into electric energy; the energy storage converter is used for storing the electric energy converted by the photovoltaic panel; a compressor; the electronic expansion valve is used for controlling the flow of the refrigerant; the electricity meter is used for detecting electricity consumption of the air conditioning unit; the controller is configured to obtain the compressor operation frequency, the electronic expansion valve opening degree and the electricity meter metering value of the air conditioning unit at the current moment; on the basis of the compressor operation frequency and the electronic expansion valve opening degree at the current moment and the trained back propagation neural network model, an ammeter derived value at the current moment is determined; and under the condition that the ammeter deviation value is greater than a preset deviation value, determining that the ammeter deviates, the ammeter deviation value being an absolute value of a difference value between the ammeter metering value and the ammeter derivation value.
