What is thermo -acoustic cooling?

Thermoocoustic cooling, such as conventional cooling, uses a unit of closed pressure. In addition to this unification, two cooling methods are very different. Instead of cooling steam, which includes complex mechanical components and gases from ozone exhaustion, it uses thermoacoustic cooling instead of the sound wave compressor to the compressor instead of creating a cooling force.

Thermoacoustic unit consists of a regenerator consisting of a regenerator consisting of a regenerator; two heat exchangers; and speaker for supplying acoustic energy. The speaker is modified to generate an extremely highly reinforced sound in Helia, an environmentally healthy inert gas that is converted into cooling energy. The sound waves are so high, about 170 decibels that they are hardly heard by people; This level is many times louder than the average rock concert. These sound levels can only be achieved in the atmosphere contained, presurised gas. American magnates of ice cream ben cohEN and Jerry Greenfield examined alternative cooling methods that were environmentally friendly. They received financial assistance from their parent company, Unilever, and joined as partners in the Penn State project.

Thermoacoustic cooling is supported as better than traditional cooling at many levels. This not only eliminates the need for most mechanical components of conventional cooling units, but also requires less maintenance and is more environmentally friendly because it uses natural inert gases. The temperature is easier to check, increasing the potential for increased efficiency and lower operating costs.

method was successfully used in the prototype to cool the unit to -11 ° F (-24 ° C). This is very below the freezing point of water and more than adequate for successful storage of ice cream. From the Penn State research, which began in 2002, many thermo -acoustic cooling units were largely developed and TESticked. The last work prototype was introduced in Ben & Jerry's Waterbury, Vermont, Earth Day Device in 2004.

There are hundreds of millions of residential, industrial and commercial cooling, freezers and air -conditioning units that use traditional cooling mechanisms and chemicals. It is believed that many traditional refrigeration gases, such as hydrochlorofluorocarbones (HCFC) and hydrophluorocarbones (HFC), have an impact on global warming, if destroyed. If the thermo -acoustic cooling method proves to be a viable and affordable alternative, a negative impact on the environment of older refrigerators could be minimized and eventually eliminated.
