New Heat Pumps Use Sound to Heat/Cool

BlueHeart Energy‘s system works like Equium’s, with acoustic drivers compressing and expanding helium within a sealed tubular circuit to achieve heat exchange. (Credit: BlueHeart Energy) New Tech could disrupt Heat Pump industry. Direct Industry: Residential heating systems are a major source of carbon emissions in the European Union, with fossil fuel-based heating accounting for approximately…

Thermo-acoustic heat pump for residential applications

Dutch researchers have developed a heat pump that can be used in combination with rooftop solar generation, due to its modulating capabilities and temperature flexibility. It measures 55 cm x 55 cm x 55

New heat pump offers increased sustainability

New heat pump offers increased sustainability 1 February 2021 BHE’s thermoacoustic technology creates a sound wave within a circuit filled with helium. Netherlands-based Blue Heart Energy (BHE) is currently developing a new thermoacoustic heat pump which can use a flexible heat source and release heat at different temperatures to achieve more sustainable heating and cooling. Thermoacoustic heat pumps will be silent, will not need refrigerants, will have a simple architecture and be more flexible, allowing them to become more affordable and easier to install. BHE’s thermoacoustic technology creates a sound wave within a circuit filled with helium. By expanding and compressing, the gas absorbs and releases heat in two different heat exchangers. The result is a heat pump capable of working with every heat source and efficiently providing the necessary temperature output, regardless of how big or small the required temperature lift.
