The Copeland heating specialist established in the US announced that it has invested an unknown sum in the Dutch thermo-acoustic heat pump developer BlueHeart Energy.
According to Copeland, BlueHeart’s thermo-acoustic heating technology is ideal for supplementing the current compressor technologies with a compact design and quiet operation, especially in the residential business.
“We are delighted to announce our strategic investments in BlueHeart, whose innovative thermo-acoustic heat pump technology complements our best-in-class Scroll-compressor portfolio,” said CEO of Copeland, Ross B. Shuster. “This investment will help BlueHeart to bring their new technology to commercial preparation and strengthens the dedication of Copeland to stimulating the global energy transition and delivering efficient, sustainable heating solutions worldwide.”
BlueHeat revealed some details about its heat pump technology in 2022. At that time it said that the system exists a 6-kW heat pump that works on acoustic waves and can produce both heat and cold air.
‘The thermo-acoustic technology is suitable for both residential and industrial applications, ”said a TNO spokesperson PV -Magazine. “However, the Blue Heart Energy solution focuses exclusively on household applications.”
The device measures 55 cm x 55 cm x 55 cm. It can be used in combination with the generation of solar energy on the roof and is said to reach higher temperatures than existing heat pumps, without the need for coolants. It works with two pistons that oscillate with a frequency of 100 Hz in a closed pressure vessel filled with 50 bar helium.
The system creates an acoustic wave that is able to move heat from a lower temperature to a higher temperature. This process takes place in four phases: expansion, relocation, compression and return displacement.
