Abstract

The invention discloses a photovoltaic air conditioning system and a control method thereof. The photovoltaic air conditioning system comprises a solar battery array, a current change unit and an air conditioning set, wherein the current change unit is connected between the solar battery array and a public power grid, and is provided with a first direct-current bus, a voltage adjusting module and a rectification inversion synchronization module connected through the first direct-current bus and a first controller both connected with the voltage adjusting module and the rectification inversion synchronization module; and the air conditioning set has a second direct-current bus connected to the first direct-current bus, an inversion module and a switching power supply connected with the second direct-current bus, and a second controller. The photovoltaic air conditioning system solves the problem that a photovoltaic air conditioning system in the prior art cannot operate off network, achieves the reduction of the dependence of the photovoltaic air conditioning system on the power grid, and reduces the cost of the photovoltaic air conditioning system.

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] figure 1 is a schematic diagram of a photovoltaic air-conditioning system in the prior art, such as figure 1 As shown, the whole system mainly includes a solar cell array 10, an air conditioner inverter 20 and a first DC bus L1, wherein the air conditioner inverter 20 includes a rectification inverter grid-connected module 21, an inverter power module 22 and a second DC bus L2. Its characteristics are: [0003] a) The direct current generated by the solar battery array 10 enters the air conditioner inverter 20 through the first direct current bus L1 . [0004] b) The rectifier and inverter grid-connected module 21 and the inverter power module 22 included in the air conditioner inverter 20 are connected through the second DC bus L2, and the first DC bus L1 is connected with the se...
