The easy-to-install machines reduce CO2 emissions by 80 per cent
Spotted: The International Energy Agency (IEA) calls heat pumps “the central technology in the global transition to secure and sustainable heating.” Although they tend to come with higher upfront costs than other heating options, their low rate of emissions and general high rates of efficiency are driving sales to record highs. Solar, wind, and hydropower are well-known renewables used to power many devices, and now French technology company Equium is introducing a new source. Thermoacoustic power transforms the energy of sound waves into heat or cold.
The company’s Acoustic Heat Pump compresses or expands high power sound waves in order to produce the desired temperature. The action requires very little power, and as the sound waves expand and contract, the movement produced is similar to that of a piston in a traditional engine, yet without the mechanical moving parts. It is possible to use the thermoacoustic pumps in most temperatures and climates, without the need for greenhouse gases.
The devices themselves are made from 100 per cent recyclable materials and are designed for extremely low maintenance, with expected product life spans of up to 30 years. They are also easy for owners to install without requiring advanced technical skills. The elimination of greenhouse gas refrigerants combined with minimal maintenance needs contribute to the new pumps’ efficiency, which further reduces long-term investment costs.
Making sources of renewable heat and electricity more affordable is a foundational element of many of the energy innovations Springwise is spotting, such as geothermal systems for individual homes, and tailored electrification plans.
