Solar-powered Containerized Cold Storage Rooms

The purpose: In countries where the Sun is shining half of the day or more, especially in developing countries where a stable electricity isn’t always assured,  lack of cold storage. The solution is green Focusun offers portable, walk-in cold rooms that work exclusively on solar energy. This reliable system is especially fit for remote locations, disaster-stricken areas or regions without a steady power grid. Smart cooling solutions mobile cold rooms have high insulation values and are manufactured according to world standards. The solar panels are connected with a system that stores extra solar energy for the night times. This smart cooling solution is eco-friendly, has low running costs and requires low maintenance. Technical information Measurements: A 40 feet or 20 feet shipping container with solar panels on top. Choice between cooling (0,5 / 5 ˚C) or freezing capacities (-24 /-18˚C). Products stay 24/7 cool or frozen, becaus […]


History of Ice Machines

The first ever patent for an Ice Machine was granted to John Gorrie in 1851 after he had perfected his 1842 invention of a system that was able to chill water to produce ice. However, his plan to manufacture the machine for the general public was thwarted by a smear campaign led by Frederic Tudor, and the death of his partner. He died four years later in 1855, humiliated and financially ruined. He lays buried in Apalachicola, at Gorrie Square, and his original machine and plans are held at the Smithsonian Institution, Washington, D.C. Alexander Twining also received a patent for an Ice Making Machine in 1853. His experiments led to the first commercial refrigeration system in the USA (1856) and he also established the first practical method for bulk producing ice by artificial means. Professor Jürgen Hans also experimented with ice creation and in 1929 he successfully developed a machine that was capable of making ice that was edible. H […]


Making the Case for CO2 Refrigeration in Warm Climates

  For a decade or more, the potential of CO2 in supermarket refrigeration has been recognized in Northern Europe. Thanks to its unique properties, notably the high heat transfer coefficients and the low sensitivity to pressure losses, CO2 delivers high performance in supermarket applications.   In warmer climates, the advantages of CO2 in food retail applications have been disputed. In recent years, however, the interest from forward-thinking retailers has fueled the invention of new technologies that make transcritical CO2 systems in warmer climates both viable and profitable. New technologies are rapidly emerging as highly energy-efficient solutions that help retailers reduce complexity and meet current and future regulation on traditional refrigerants. In this article, we will explore the pros and cons of different solutions for CO2 refrigeration in warmer climates – from basic cascade systems to the advanced ejector techno […]
