Working Principle Of Thermoacoustic Heat Pumps
Thermoacoustic Heat Pumps are devices that convert sound waves into thermal energy. They have a stack of plates or tubes and a gas like helium or air. An engine or electric motor compresses the exhaust air, creating standing acoustic waves in the stack producing a temperature difference between its two ends due to the mean and critical temperature gradients.
The hot end is the heat source; the cold end is the sink. There’s a heat exchanger to transfer thermal energy from the hot to the cold circuit. The Carnot Efficiency determines the maximum performance for these devices. Water or helium are ideal refrigerants for thermoacoustic engines.
Thermoacoustic devices have many advantages including lower emissions, high efficiency, and low maintenance costs. Blue Heart Energy is a big player in the industry.
