ABSTRACT:
This invention is a gas wave refrigeration method and a corresponding device used in an energy recovery system, which employs a mechanism creating a pulsating flow wave resonant interactions to generate cooling and heating effects without any mobile parts used in the device. The said system includes a precooler, a gas-liquid separator, and a gaseous wave refrigeration device (GWRD). The GWRD consists of a flow buffering chamber, a convergent nozzle, a oscillating chamber, resonant tubes, and a flow stabilizer. The operation of the GWRD is based on a pulsating flow production created by wave interactions between laterally oscillating high speed jets and resonant tubes. Such method of the pulsating flow production omits a conventional bistable element or other flow switching elements used in prior similar devices. A longitudinal resonating phenomenon of resonant tubes which provides a energy transformation and cooling effect is produced simultaneously by such wave interaction process. By means of this method and device, the energy recovery system provides an effective operation in a wide range of working conditions of pressurized gases in separation and liquefaction applications.
