Photovoltaic energy storage air-conditioning device and control method thereof

Abstract

The invention discloses a photovoltaic energy storage air-conditioning device and a control method thereof. The air-conditioning device comprises a photovoltaic power generation device, an energy storage device, an air-conditioning unit and an energy dispatching management device. The energy dispatching management device comprises a detection module which is used for detecting the air-conditioning operation state and the power supply quantity and the working state of the photovoltaic power generation device and the energy storage device; and a dispatching module which is used for controlling power supply and / or charging according to the air-conditioning operation state, the power supply quantity and the working state and the preset power supply priority and the power consumption priority. According to the photovoltaic energy storage air-conditioning device and the control method thereof, the air-conditioning device can operate under different working modes according to the change of the actual situation of power generation, power storage and power consumption so that real-time operation of multiple working modes can be realized, the influence of weather changes, the storage battery capacity and the operation state of the power grid on normal operation can be reduced and the stability and the reliability can be enhanced. Besides, photovoltaic power generation consumption is not wasted, the influence of charge and discharge on the service life of the storage battery is low and benefit maximization can be realized.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a photovoltaic energy storage air conditioning device and a control method. Background technique [0002] Energy shortage is a more serious problem currently faced, and one of the solutions to this problem is to use solar power to generate electricity. The existing relatively mature photovoltaic air-conditioning systems are mainly used in conjunction with photovoltaic power and municipal power. When the system is affected by some objective factors (such as darkness, power outages, weather changes, etc.), the photovoltaic air-conditioning system may not operate normally. At present, some concepts of photovoltaic energy storage air-conditioning systems have been proposed. Energy storage units are added to the photovoltaic air-conditioning system to form a photovoltaic energy storage air-conditioning system architecture to ensure energy supply and normal operation. However...
