Abstract

The invention discloses a photovoltaic air conditioning system which comprises a photovoltaic battery array, an air conditioning unit, a current transforming unit and a direct-current bus. The current transforming unit is disposed between a public power grid and an inversion module. The capacity of the current transforming unit is configured according to needs of the photovoltaic battery array or the public power grid. The inversion module serving a standard accessory of the unit is disposed on the air conditioning unit. Direct current emitted by the photovoltaic battery array and the direct current emitted after being rectified by the current transforming unit are supplied to the inversion module so as to power the air conditioning unit. By the system, the problem that the photovoltaic air conditioning systems are poor in adaptability in the prior art can be solved. The photovoltaic air conditioning system is capable of adapting to photovoltaic power stations of different capacities, and enabling the photovoltaic power stations to be seamlessly and efficiently combined with heating ventilation air conditioners.
