Magnetic Refrigeration Market – How the Market Will Witness Substantial Growth in the Upcoming years

Jul 23, 2020 (Market Insight Reports) -- This detailed market report focuses on data from different primary and secondary sources, and is analyzed using various tools. It helps to gain insights into the market’s growth potential, which can help investors identify scope and opportunities. The analysis also provides details of each segment in the global magnetic refrigeration market

According to the report, magnetic refrigeration technology is utilized for cooling purposes using the magnetocaloric effect, otherwise called adiabatic demagnetization. The innovation is regularly utilized in refrigerators to accomplish outstandingly low temperatures. Magnetic refrigeration doesn't use hydrofluorocarbons, which are generally harmful and ozone-depleting coolant gases.

Major companies functioning in the market are Whirlpool Corporation, Toshiba, Astronautics Corporation of America, Samsung Electronics, General Electric, BASF, Camfridge, Eramet, and Haier...

Key Factors Impacting Market Growth:

•   High product lifecycle, improved efficiency, low maintenance cost, etc., are fueling market growth

•   Concerns over ozone layer depletion are resulting in stricter regulations on refrigerants

•   High market potential in industrial and transportation sectors

•   Need for proper magnetocaloric materials can be a challenge for market growth

Keep cool: Researchers develop magnetic cooling cycle

As a result of climate change, population growth, and rising expectations regarding quality of life, energy requirements for cooling processes are growing much faster worldwide than for heating. Another problem that besets today's refrigeration systems is that most coolants cause environmental and health damage. A novel technology could provide a solution: refrigeration using magnetic materials in magnetic fields. Researchers at the Technische Universität (TU) Darmstadt and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed the idea of a cooling cycle based on the 'magnetic memory' of special alloys. Relevant initial experimental results have now been published in Nature Materials.

The magnetic properties of metals can change when they are heated or cooled. "Iron, for example, is only ferromagnetic below 768 degrees Celsius; nickel's transformation temperature is 360 degrees Celsius," says Oliver Gutfleisch, Professor of Functional Materials at the TU Darmstadt. "Conversely, some alloys become ferromagnetic when they warm up. This phase transition is connected with the so-called magnetocaloric effect: when these shape-memory alloys are placed in an external magnetic field just below their transformation temperature, they spontaneously jump to their magnetic order and simultaneously cool down," explains Gutfleisch. "The stronger the magnetic field, the more they cool."

Dr. Tino Gottschall, who is now researching at the HZDR's Dresden High Magnetic Field Laboratory (HLD), and his colleagues have studied different shape-memory alloys and their properties in minute detail: "The application of a magnetic field can also change other properties, for example density – which is why some alloys increase their volume." The physicists discovered that externally applied pressure can indeed reverse the magnetization process, causing the alloy to heat up.

Very cool.  I sure hope an HVAC application can be used in the auto industry.  Esp. since AC jobs are now usually $1000 repair when compressor/Evap Coil issues are involved.  I know refrigeration and HVAC are separate aspects, but.......

I display the Confederate Battle Flag in honor of my great great great grandfathers who spilled blood at Wilson's Creek and Shiloh.  5 others served in the WBTS with honor too.

Do you stick them on the door?
