Title:
PHOTOVOLTAIC AIR CONDITIONING SYSTEM, CONTROL METHOD THEREFOR, AND PHOTOVOLTAIC AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2024/087763
Kind Code:
A1
Abstract:
The present disclosure provides a photovoltaic air conditioning system, a control method therefor, and a photovoltaic air conditioner. The photovoltaic air conditioning system comprises a photovoltaic cell, a direct current bus capacitor and a direct current load that are connected to the photovoltaic cell, and a DC/AC circuit that is connected to the direct current bus capacitor and an alternating current grid. The photovoltaic air conditioning system further comprises a conversion circuit disposed at an output terminal of the photovoltaic cell, the conversion circuit being used to match the direct current load and adjust an output voltage of the photovoltaic cell. The present disclosure causes a direct current bus voltage to maintain operation within a specified range by means of configuring a conversion circuit, which resolves the problem that, when photovoltaic power generation is connected to an existing photovoltaic air conditioning system, a DC/DC converter is always in step-up operation, and system power and a quantity of configured photovoltaic battery panels are limited.
