Abstract

The invention discloses a photovoltaic air-conditioning system and a control method thereof. The photovoltaic air-conditioning system comprises a solar photovoltaic power generation assembly, a converter, an air-conditioning unit, an energy storage assembly and an electric energy comparison assembly, wherein the converter is connected with the solar photovoltaic power generation assembly and an alternating current network, and the electric energy comparison assembly is connected with the converter, the air-conditioning unit and the energy storage assembly and used for determining a power supply of the air-conditioning unit according to output electric energy of the solar photovoltaic power generation assembly, consumed electric energy of the air-conditioning unit, the power supplying stateof the alternating current network and stored electric energy of the energy storage assembly. According to the photovoltaic air-conditioning system and the control method thereof, the problem that the power supply of an air conditioner in the prior art is single is solved, and further the effects that power supplying modes of the air-conditioning unit are enriched, and stable and reliable operation of the air-conditioning unit is ensured are achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a photovoltaic air conditioning system and a control method thereof. Background technique [0002] At present, air conditioners are generally powered by a single mains power supply, which not only consumes a lot of energy and costs more, but also in the case of a mains power failure, the air conditioner can only stop running. This kind of stop operation not only brings inconvenience to the user of the air conditioner, but is more likely to cause an emergency stop failure of the air conditioner due to a sudden power failure, which affects the operational stability and service life of the air conditioner. [0003] Aiming at the problem of the single power supply of the air conditioner in the related art, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present invention is to provide a photovoltaic air-conditioning system and...
