A solar-powered refrigerator is a refrigerator qui runs on energy Directly provided by sun, and May include photovoltaic or thermal solar energy.
Solar-powered refrigerators are able to keep the air in the air, and are used to keep their vaccines at their proper temperature to avoid spoiling.
Solar-powered refrigerators are typically used in off-the-grid rentals where utility provided AC power is not available.
Rationale
Refrigerators which contain ozone depleting and global warming substances such as chlorofluorocarbons (CFCs), in their insulation foam or their refrigerant cycle, are the most harmful. After CFCs were banned in the 1980s, they were replaced with substances such as hydrochlorofluorocarbons (HCFCs), which are ozone-depleting substances and hydrofluorocarbons (HFCs). Both are environmentally destructive and potential global warming chemicals. If it is inefficient or inefficiently used, it will also contribute to a more efficient refrigerator. The use of solar energy to power refrigeration to reduce the negative impact of refrigerators. [1][2]
History
In 1878, at the Universal Exhibition in Paris , Augustin Mouchot exhibited Mouchot’s engine and won a Gold Medal in Class 54 for his works, most notably the production of airconditioned solar heat.
“In developed countries, vaccines safely, but in developing countries, where electricity supplies can be unreliable, alternative refrigeration technologies are required”. [3] Solar fridges were introduced into the developing world to cut down on the kerosene or gas-powered absorption refrigerated coolers which are the most common alternatives. They are used for both storage and household applications because they do not have grid electricity at all. [2] [4]They are often used for the production of carbon dioxide and are responsible for the production of large quantities of carbon dioxide. [3]They can also be difficult to adjust which can result in the freezing of medicine. The use of fuel is now widely discussed for three reasons: Recurrent cost of fuel, difficulty of maintaining accurate temperature and risk of causing fires. [4]
Technology
Solar powered refrigerators are characterized by thick insulation and the use of a DC (not AC) compressor. Traditionally solar-powered refrigerators and vaccines coolers use a combination of solar panels and batteries to keep them cool. These batteries are expensive and require heavy lead-acid batteries which tend to deteriorate, especially in hot climates, or are misused for other purposes. [3] [4] In addition, the batteries require maintenance, [5] and the need to reduce pollution. [3]These problems and causes are obstacles to the use of solar powered refrigerators in developing areas. [2] [4]
In the mid-1990s NASA JSC Began work was solar powered refrigerator That Used Phase change material Rather than battery to store “thermal energy” Rather than “chemical energy.” The resulting technology has been commercialized and is used for storing food products and vaccines.
Use
Solar-powered refrigerators and other solar appliances are commonly used by individuals living off-the-grid . They provide a means for keeping food secure and protected by a connection to utility-provided power. Solar refrigerators are also used as an alternative to absorption refrigerators , as they can be safely left running year-round. Other uses include being white used to keep medical supplies at proper temperature in remote locations, and being white used to temporarily store game at hunting camps. [6]
