Abstract

The invention relates to a solar energy photovoltaic energy storage refrigerator system comprising a solar energy photovoltaic energy electricity generation system and a refrigerating circulation system of a refrigerator. The solar energy photovoltaic energy electricity generation system comprises an solar energy photovoltaic battery array, a reverse charging prevention diode, a controller, an accumulation battery set, and an AC-DC inverter. The refrigerating circulation system of a refrigerator comprises a compressor, a condenser, a first electromagnetic valve, a first trotting device, a second trotting device, a chilling chamber evaporator, a chilling chamber regenerator, a regenerating chamber evaporator and a regenerating chamber regenerator. The regenerator stores the excessive cold quantity when electricity is enough and releases the cold quantity when it is raining or electricity is lack. The inventive refrigerator can replace normal refrigerators, and is provided with characteristics of energy-saving, environmental protection and safety. Reproducible resources are utilized and mineral energy consumption is reduced.

Description

technical field [0001] The invention relates to a solar refrigerator, in particular to a solar photovoltaic energy storage refrigerator system. Background technique [0002] As a clean energy source, solar energy is both a primary energy source and a renewable energy source, and has incomparable advantages over fossil energy sources. According to calculations, the sun can release 391×10 21 kW of energy, and although the energy radiated to the surface of the earth is only 1 / 2.2 billion, it is equivalent to 80,000 times the current total power generation in the world. Therefore, solar energy resources are very rich, and it is the most eye-catching, most developed and most widely used clean energy among renewable energy sources. At present, the utilization of solar energy mainly includes photothermal utilization (such as solar water heaters, etc.) and photoelectric utilization (such as solar cells). Photoelectric utilization (such as solar cells) is not yet common. Refriger...
