Is there a way to create environmentally safe method of air conditioning?
Based on the principles of the Stirling engine, SoundEnergy has developed a solution using thermo acoustic technology, which can convert industrial waste heat or solar heat into a cooling system, called THEAC. The THEAC system uses no mechanical moving parts, no refrigerants, no CO2, no precious metals or materials. Instead it uses Argon gas, which is plentiful and has zero global warming potential, and is totally sustainable, relying solely on the energy of incoming heat to produce cold.
This technology is ran on “thermoacoustic effects”, which produces a loud and monotone sound when hot bulbs are blown at the end of a cold, narrow tube. Here the temperature differential is crucial, as the volume and intensity of the sound varies with the length of the tube and the size of the bulb. Gases expand and contract with heat, meaning that a temperature differential can create a pressure differential. This is the principle behind the operation of the Stirling engine, and it’s the source of the pressure waves that were causing sonic oscillations in the glass tubes.
The THEAC technology has a potential ability to reduce global energy usage while efficiently scavenging waste heat at an efficiency of 40-50 percent.
As production scales up, it will be possible to create residential products at much lower prices. Each system should have an expected lifespan of around 20-30 years, which is certainly better than a conventional air con unit.
