Recycling waste heat into energy using thermoacoustic technology

July 2019
Gallery EQUIUM 1
Gallery EQUIUM 1


EQUIUM recycles waste heat of exhaust gas into cooling to enhance energy efficiency of systems.

The solution offers a new way for the production of cooling in the CCHP (Combined Cooling and HeatPower) process, also known as trigeneration process, using thermoacoustic technology. This technology converts heat energy into work in the form of acoustic energy, using the effects that arise from the resonance of a standing-wave in a gas. It is a completely passive process with automatic and silent equipment. Additionally, there is no use of negative environmental impact fluid, such as refrigerants, along with lower CO2 and NO2 emissions.
