Newly Discovered Material Expected to Change Cooling Industry

Refrigeration and air conditioning may become more efficient and environmentally friendly thanks to the patent-pending work of LSU physicists. The team of researchers led by LSU Physics Professor Shane Stadler has discovered a breakthrough magnetocaloric material that may change the energy industry, including air conditioning and food refrigeration. “The world refrigeration market is expected to increase by about $7-8 billion by 2018,” Stadler said. Therefore, his breakthrough has a significant economic impact as well as an impact on the energy industry and environment. Stadler’s research focuses on the next generation of magnetic cooling technologies, which are simpler in design, quieter and more environmentally friendly than conventional compressed-gas systems currently used. “LSU’s basic research into low-temperature physics and materials science has potential applications in areas related to energy, ele […]

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 […]

Advantages and Disadvantages of Each Compressor Type

Advantages and disadvantages of any compressor are based on its characteristics and application. Advantages and disadvantages listed below are for a typical compressed air system in an industrial plant. The estimated full‐load bhp requirement of each compressor type at 100 psig discharge pressure at the compressor, a main drive motor typical efficiency of 92 percent and 0.746 kilowatts (kW)/bhp, the approximate operating costs of operation are obtained. Single‐Acting, Air‐Cooled Reciprocating Air Compressors Advantages include Small size and weight Generally, can be located close to point‐of‐use avoiding lengthy piping runs and pressure drops Do not require separate cooling systems Simple maintenance procedures. Disadvantages include: Lubricant carryover as piston rings wear, which should be avoided Relatively high noise Relatively high cost of compression Generally, are designed to run not more than 50 percent of the time, although som […]

How Solar Cells Work

You’ve probably seen calculators with solar cells — devices that never need batteries and in some cases, don’t even have an off button. As long as there’s enough light, they seem to work forever. You may also have seen larger solar panels, perhaps on emergency road signs, call boxes, buoys and even in parking lots to power the lights. Although these larger panels aren’t as common as solar-powered calculators, they’re out there and not that hard to spot if you know where to look. In fact, photovoltaics — which were once used almost exclusively in space, powering satellites’ electrical systems as far back as 1958 — are being used more and more in less exotic ways. The technology continues to pop up in new devices all the time, from sunglasses to electric vehicle charging stations. The hope for a “solar revolution” has been floating around for decades — the idea that o […]

History of refrigeration

In the 1800s natural refrigeration was a vibrant part of the economy. Natural ice harvested from the pristine rivers and lakes of the northern United States, particularly those in New England, was in demand. Harvested ice was stored in large quantities in ice houses and covered with sawdust for insulation. Later, merchants loaded the ice in sailing ships as ballast. Again, the ice was covered with sawdust. Ice was delivered to as far away as India, where it was welcomed, and to England, where interest was low. The supply of harvested ice was erratic, depending on the weather where it was harvested. During the 1800s many mechanical-type refrigeration systems were being invented and used refrigerants such as sulfur dioxide, methyl chloride, ether, carbon dioxide, as well as wine, brandy, vinegar, etc. The early refrigeration systems designed between 1850 and 1920 produced ice year-round to compete with harvested ice. The harvested ice pro […]

World Refrigeration Day announced as June 26

Industry trade associations and professional bodies from across the globe have come together to establish June 26 as World Refrigeration Day, which will be celebrated the world over as an annual event. The entire worldwide industry is encouraged to take the opportunity to promote the significant role of refrigeration, air conditioning and heat pumps in the well-being of mankind. It is intended that World Refrigeration Day will serve as a means of raising awareness and understanding to the general public of the significant role that the industry and its technology play in modern life and society, with RACHP and HVACR organizations and professionals around the world undertaking a range of activities. The term ‘refrigeration’ here is being used in its widest sense as the process of achieving and maintaining a required temperature below that of its surroundings. An example of refrigeration is the preservation and distribution of perishable […]
