Thermoacoustic technology has been researched and developed by leading scientific institutions and government laboratories for decades
Pioneering research in thermoacoustic technology originated at Los Alamos National Laboratory (LANL), one of the world's premier research institutions. Scientists at LANL working for the Department of Energy and NASA developed the foundational theories and practical applications of thermoacoustic engines and refrigerators in specialized laboratories.
The physical theory of operation is now well-established and taught in over 15 major universities across the United States. Our engineering team includes inventors who are patent holders and worked directly with these pioneering institutions.
Comprehensive academic resources on thermoacoustic engineering principles provide detailed explanations of how sound waves interact with temperature gradients to create powerful cooling and heating effects.

Watch VideoUnderstanding the regulatory landscape driving the transition away from harmful refrigerants toward sustainable cooling solutions
The Environmental Protection Agency has implemented a comprehensive phaseout of ozone-depleting substances, including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). The production ban concluded at the end of 2025, accelerating the urgent need for alternative cooling technologies.
Learn more about ozone layer protection and why eliminating harmful refrigerants is critical for environmental preservation.
Industry experts warn about the rise of propane sparking safety fears in HVAC systems. The shift to flammable refrigerants has raised significant concerns among lawmakers and industry professionals.
Read ReportConsumer Reports details how the EPA issued warnings on flammable AC refrigerants, highlighting the risks associated with current alternative cooling solutions and the need for safer technologies.
Read WarningThe EPA ban on common coolants has lawmakers and industry worried about the transition period and available alternatives. This regulatory pressure creates an urgent market need for safe, effective, and environmentally friendly cooling technologies like thermoacoustics.
Cool Sound Industries' Solution: Our thermoacoustic technology uses only inert gases—completely non-toxic, non-flammable, and with zero ozone depletion potential or global warming impact.
Understanding why eliminating harmful refrigerants is critical for our planet's future
The largest ozone hole ever seen opened over Antarctica—a sign that ozone-depleting gases churned out years ago are just now coming to their peak. The hole spreads over about 11 million square miles (28.3 million square kilometers).
This unprecedented assault on the planet's life-support system will have long-term effects on human health, animal life, the plants which support the food chain, and virtually every other life form that makes up the delicate web of nature.
For nearly a billion years, ozone molecules in the atmosphere have protected life on Earth from the effects of ultraviolet rays. In the past 60 years, human activity has contributed to the deterioration of the ozone layer.
Only 10 or less of every million molecules of air are ozone. The majority of these ozone molecules reside in a layer between 10 and 40 kilometers (6 and 25 miles) above the Earth's surface in the stratosphere.
Each spring in the stratosphere over Antarctica, atmospheric ozone is rapidly destroyed by chemical processes. When temperatures drop below -78°C (-109°F), thin clouds form of ice, nitric acid, and acid mixtures.
Chemical reactions on ice crystal surfaces release active forms of CFCs. Over two to three months, approximately 50% of the total ozone disappears. At some levels, losses approach 90%.
After rigorous negotiations, the Montreal Protocol on Substances that Deplete the Ozone Layer was agreed upon on September 16, 1987. It stipulates that the production and consumption of chlorofluorocarbons (CFCs), carbon tetrachloride, and methyl chloroform are to be phased out by the year 2025.
More than 170 nations signed the historic Paris Climate Agreement on April 20, 2016—an important step toward putting the treaty into effect and eliminating greenhouse gases by 2050.
Man-made chlorines, primarily chlorofluorocarbons (CFCs), contribute to the thinning of the ozone layer and allow larger quantities of harmful ultraviolet rays to reach the earth. Most air-conditioning and refrigeration units used today use some form of ozone-destroying or planet-warming fluids.
The freons which have already escaped—and continue to escape—represent an unprecedented assault on the planet's life-support system, with horrendous long-term effects on human health, animal life, and the entire food chain for years to come.
Federal funding and international climate initiatives are driving innovation in sustainable HVAC technology
