Abstract

A method for inputting a current into an air conditioning unit. The method comprises: acquiring power consumption of an air conditioning unit, power consumption of a photovoltaic system of an air conditioner, and loss power of the photovoltaic system of the air conditioner, and acquiring a photovoltaic system voltage value sent by the photovoltaic system of the air conditioner (S12); generating a reference current according to the power consumption, the loss power of the photovoltaic system of the air conditioner, and the photovoltaic system voltage value (S14); and issuing the reference current into an inverter of the photovoltaic system, the inverter controlling the magnitude of a current output to the air conditioning unit according to the reference current (S16). The technical problem of grid connection of a photovoltaic system resulting from a situation where the output power of the photovoltaic system is much higher than the power consumption of an air conditioner can be resolved. Also disclosed is an apparatus for inputting a current into an air conditioning unit.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and device for inputting current of an air conditioner unit. Background technique [0002] The generation of photovoltaic air-conditioning has set off a new revolution in new energy air-conditioning technology. The photovoltaic system converts solar energy into electrical energy through an inverter, and the photovoltaic system then transmits the electrical energy to the air-conditioning unit for power supply, which greatly saves energy consumption. [0003] It should be noted that in some cases, the power generated by the photovoltaic system will be greater than the power consumption of the air conditioner unit, which will lead to excess electricity generated by the photovoltaic system, so that the photovoltaic system will be integrated into the grid, and the grid integration of the photovoltaic system will lead to grid failure. system disorder. At present, the methods t...
