Abstract
A compression and expansion system includes a pressure vessel having a variable volume working chamber therein. The pressure vessel has a conduit through which at least one fluid can be introduced into and discharged from the working chamber. The system further includes a heat transfer element disposed within the working chamber and including a layer and at least one of a fin and a spacing element. The pressure vessel is operable to compress fluid introduced into the working chamber such that heat energy is transferred from the compressed fluid to the heat transfer element, and is further operable to expand fluid introduced into the working chamber such that heat energy is transferred from the heat transfer element to the expanded fluid.
