Solar power applications on Cold storage

Fishermen in Somalia which is located on the in the east of Africa, have no electricity. But for the past year they have been able to store their fish on cold rooms: Four cold storage rooms, powered by nothing but the scorching sun, with a capacity of storing 30 ton of fish per day. There’s a global scramble to drive down emissions of carbon dioxide: the electricity to power just refrigerators in the U.S. contributes 102 million tons annually. Solar refrigeration can also be inexpensive and it would give the electric grid much-needed relief. Electricity demand peaks on hot summer days—150 gigawatts more in summer than winter in the U.S. (A gigawatt equals one billion watts.) That’s almost 1.5 times the generating capacity of all the coal-fired power plants west of the Mississippi River. Further, solar is plentiful. The solar energy hitting 54 square feet (five square meters) of land each year is the equivalent of all the ele […]

Refrigeration is important for maintaining a proper, unbroken cold chain. Using dairy as an example, after the cows are milked, their milk is pasteurized and rapidly chilled. Once the milk has been chilled, it must be maintained at that low temperature from the farm to the grocery store, including during bottling and shipping. If the cold chain is broken, bacteria or fungus can grow, making the food unsafe for human consumption. The United States Department of Agriculture requires that business-owned refrigeration systems have an internal temperature of 40°F or below for refrigerated food and 0°F for frozen food1. Businesses operating refrigerators or freezers above these temperatures face fines and other penalties, so maintaining a reliable temperature is imperative. One of the most popular types of business-owned refrigeration systems is the cold room. Cold rooms are staples of restaurants, hotels, supermarkets, and any other place th […]
