This invention provides a gaseous wave refrigeration device (GWRD) primarily comprising an adjustable nozzle, an adjustable oscillating chamber, a bundle of resonant tubes, a flow regulator, wave impedors, and a chiller to monitor the gaseous wave behavior in GWRD and to produce the refrigeration effectively in the condition of varying flow state through GWRD. This characteristic is achieved by means of controlling resonant periodic flow phenomenon of gaseous column and wave interactions through the adjustment of said adjustable nozzle and adjustable oscillating chamber under varying conditions of flow states in pressurized supplying gas streams to retain the optimal performance of GWRD. With this characteristic, the GWRD in the present invention can be applied in practices to fit the controlling requirements on fluctuations of system operations in industries.

[ The invention having been thus described, what is claimed as new and desired to secure by Letter Patent is:] [1.] A gaseous wave refrigeration apparatus comprises(a) a gaseous wave refrigeration apparatus having an adjustable nozzle, an adjustable oscillating chamber connected to said adjustable nozzle, a plurality of resonant tubes having open ends connected at apertures to said adjustable oscillating chamber penetrating thermal isolated connectors, and a flow stabilizer crossing over lower side of said adjustable oscillating chamber at the apertures of said resonant tubes, and wave impedors connected to the other ends opposite to said apertures of said plurality of resonant tubes, and a chiller embedding said resonant tubes at the other ends opposite to said apertures,(b) a resonant refrigeration means for varying flow state, using a pulsating flow of a laterally periodic jet oscillation from said adjustable nozzle in said adjustable oscillating chamber driven alternatively by each of said resonant tubes under varying flow conditions, wherein said jet oscillation under varying flow state, maintained by an adjustable pressure positive feedback loop comprising said stabilizer and said resonant tubes, couples with said adjustable oscillating chamber to create the intrinsic resonant frequency of a gaseous column in said resonant tubes under the varying flow state and governs a resonant cooling effect accompanied with said intrinsic resonant frequency of gaseous column in said resonant tubes under the adjustment of said adjustable nozzle and said adjustable oscillating chamber.
