SoundEnergy, the company released the first commercial version of THEAC conditioning that uses thermoacoustic technology. It does not need an external power source, requires no consumables and, in the future, will be able to save humanity from hunger energy with further heating of the atmosphere. And yet, this technology relates to environmentally friendly and does not create emissions.
About the property of heat to turn into the sound knew it was in the medieval glassblowers who noticed strange effects when working with the molten glass mass and long tubes. During the 1850s, a physicist Pieter Rijke revealed this secret – with significant fluctuations of temperature in a confined environment, the gas begins to expand and contract, creating vibrations of the atmosphere. And the sound, an acoustic signal, as a variation. It is only necessary to calculate the coefficients, and in the end, physicists have learned to generate thermoacoustic waves and send them using energy at a distance.
Feature of thermoacoustic systems is that the temperature is converted to sound in both directions without loss of energy. The principle of operation of the air conditioner in many respects similar to the operation of the Stirling engine external heat heats the gas in the pipe creates a pressure wave passes to the heat exchanger, where the reverse pressure drop, and the medium is cooled. Then the gas, harmless in this case argon, is re-circulated in a heating chamber. No pumps, fans and moving parts, some valves, and that causes a lifetime of conditioning in 20-30 years at least.
The heat source can be anything, even sunlight sheet metal, and cold can be fed in the chest freezer, and ventilation of the building. A demonstration plant with a capacity of 25 KW from SoundEnergy THEAC air cools to -25°. The development of such systems began in the 80-ies of the last century, they were used in the Space Shuttle program Discovery, but previously had difficulties with the transmission of acoustic waves and the automation cycle. Now the first commercial thermoacoustic air conditioning price of $50,000 already sold in Dubai. It is expected that the growth in the production of orders of new products will be substantially cheaper and they will become extremely popular in the future.
