WebbThermoacoustic engines (sometimes called "TA engines") are thermoacoustic devices which use high-amplitude sound waves to pump heat from one place to another (this requires work, which is provided by the loudspeaker) or use a heat difference to produce work in the form of sound waves (these waves can then be converted into electrical … Webb13 jan. 2016 · Abstract. Ground coupled heat pump (GCHP) is an efficient air-conditioning technology, which is good to sustainable development of energy use. In order to make GCHP system operate efficiently in long term, soil needs to be maintained heat balance in an annual cycle. If necessary, auxiliary heat or cold source is also needed.
