ABSTRACT:
The purpose of regenerative heat exchangers is to transfer the heat from one step or process of a cycle or system to an earlier step or process in the cycle or system such that the transferred heat is usefully absorbed rather than being discarded. The gas being heated is moved in a counter flow relative to the hotter fluid while being trapped between moving partitions (vanes) such that the gas so trapped is heated with a fixed volume with an increase in pressure as well as temperature. In some embodiments, the hotter as well as the cooler fluid is moved while trapped between moving partitions (vanes) so, as the cooler fluid being heated is thermally pressurized, the hotter fluid being cooled with a fixed volume is thermally pressurized. Materials and design details are selected to enhance the heat transfer between the two streams. The heat transfer at constant volume and thermal pressurization and depressurization will improve the energy efficiency of many processes that require a pressure increase/decrease along with heating/cooling. This invention accomplishes compression/decompression and heating/cooling with only one device rather than with two devices.
