What things you didn't know about solar refrigerators ?

Definition of solar refrigerators
according to Wikipedia, a solar-powered refrigerator is a refrigerator which runs on energy directly provided by sun, and may include photovoltaic or solar thermal energy.

The classification of solar refrigerators:

Solar refrigerators mainly include solar photovoltaic refrigerators and solar semiconductor refrigerators.

History:

At the Universal Exhibition in Paris in 1878, Augustin Mouchot demonstrated an engine, which made he won a gold medal in Class 54, the most famous work is the production of ice using concentrated solar heat. In 2019, a solar-powered portable refrigerator with a brushless compressor, lithium batteries and solar panels was launched. The unit keeps food fresh and drinks cold without ice, and can also charge phones.

Advantages of solar refrigerators:

For traditional refrigerators, due to the special use, a large amount of energy is consumed every year, which pollutes the environment indirectly. Realizing the technological development and application of solar energy is of great significance to the construction and development of the refrigerator industry.

Solar refrigerators can effectively reduce the consumption of resources, but also reduce the pollution of the natural environment. As a new type of energy refrigerator, energy & power saving, high efficiency and green environmental protection are its biggest advantages. It is a project that countries around the world strongly encourage from a long-term perspective. In recent years, it has been deeply concerned and loved by people.

Use:

Solar-powered refrigerators and other solar devices are commonly used by individuals living off-the-grid. They provide a methods for keeping food fresh and preserved while avoiding a connection to utility-provided power. Solar refrigerators are also utilizeed in cottages and camps as an alternative to absorption refrigerators, as they can operate safely year-round. Other uses, solar refrigerators include being used to keep medical supplies at the proper temperature in remote areas; in addition, for temporary storage of game at hunting camps.
