Common uses Refrigerators Home space heating/cooling Home water heating Swimming pool

More uses of heat pumps Laboratory plate/spot heating

Heat Generated Cooling Thermoacoustic Technique Using waste heat from car to generate sound When sound waves cycle through compression and expansion, it drives a heat pump that cools the car A thermoacoustic system, compared to a A/C system, may be reliable, have a long lifetime, and be environmentally safe, but it currently has a low energy density, therefore taking up a large volume. It also may be limited in terms of how much energy it could produce.
