Hot sound refrigeration

1. Basic principles:

Simply put, the thermal acoustic effect is a physical phenomenon of acoustic self-excitation oscillation caused by heat in an elastic medium (often a high-pressure inert gas).

The thermal acoustic reverse effect can be used to transport heat from low temperature to high temperature through sound waves (alternating mechanical energy). When the high temperature end is fixed at the ambient temperature, the temperature of the low temperature end will continue to decrease and realize the function of refrigeration.

1.  Features:

Instead of using polluting refrigerant, the inert gas and its mixture are used as working medium, so it will not cause CFCs and HFCs to destroy the ozone layer and pollute the environment; no sealed lubrication, no moving parts, to prolong the life.
