The Thermo Acoustic Energy Converter, THEAC-25, developed by SoundEnergy will function as a central unit in the installation concept for climate control. It’s core function is converting heat into cold by using thermo acoustic technology. Feeding heat input into one side of the THEAC-25 results into cold output at the other side, enabling the production of cold water or cold air. The output of the THEAC-25 can reach temparatures below −30°C.
The THEAC-25 is built with sophisticated technology, not using chemicals. Traditional air conditioning systems use chemical fluids that are highly damaging to the environment. The global warming potential of these refrigerants is rated 2.000 (GWP=2.000).
The working fluid in the THEAC-25 is Argon, which is an inert gas. It is easily available: about 0.94% of our atmosphere consists of Argon. And more important: Argon has zero global warming potential (GWP=0).
The THEAC-25 operates without any mechanical moving parts or precious materials. The system is maintenance free yielding a service life of at least 30 years.
The pressure inside the THEAC-25 is 10 bar. This is comparable to gas cylinders and LPG-tanks in cars. Therefore, the construction of the THEAC-25 complies to the Pressure Equipment Directive (PED).
The heat source for the THEAC-25 is not only useful to produce cold. It can also be used to feed the heating system. During a big part of autumn and winter, the hot water from the VTC-panels still reaches temperatures over 40°C. This heat can be fed directly into the heating system of the building. The result is a full use of the gained heat throughout the year.
For waste heat, this secondary use needs no explanation.
The big advantage of an installation concept based on the THEAC-25, is that there is one, integrated system for heating and cooling.
Contributing to the heating system can be seen as a secondary function of the THEAC-25 concept, but the impact in reducing gas consumption can be significant. By using storage buffers, in many cases, it can supply enough energy to take the building of completely off the gas grid and create a situation of a 100% zero CO2 climate control.
How the THEAC-25 can best be applied in climate control, what the possibilities and limitations are, depends on the specific nature and demands regarding the building. It will always require the involvement of installation experts who are in charge of the overall climate control concept.
