China achieves 270 °C industrial heat without fossil fuels using a thermoacoustic heat pump
Scientists at the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences built a heat pump that reaches 270 °C using sound waves and no moving mechanical components. According to results published in the journal Energy, the system recovers heat at about 145 °C and raises it to a higher temperature. In the experiments one unit required a heat source of about 300 degrees and a thermal power of 2.7 kilowatts was achieved, with efficiency falling as the output temperature rose.
In 45 seconds
- The prototype uses thermoacoustics: sound waves and pressure and temperature changes in a gas, without pistons or mechanical compressors.
- It recovers heat at about 145 °C and delivers it up to 270 °C, with a heat source of roughly 300 degrees in one of its units.
- It reached about 2.7 kilowatts of thermal power and its efficiency dropped as the output temperature increased.
