Abstract: An arrangement is disclosed for energy transformation under the utilization of an oscillating gas volume sustained by an energy supplying device. A gas compression creates an elevated temperature and a gas decompression creates a reduced temperature within the gas volume. One or more first valves are connected to the space, wherein the first valve is controllably actuatable to supply or extract thermal energy to or from the space during a compression stage. One or more second valve are further connected to the space, wherein the second valve is controllably actuatable to supply or extract thermal energy to or from the space during a decompression stage. A control unit is adapted to briefly permit actuation of the first valve and the second valve within mutually discrete time intervals.
Abstract: A method and an arrangement for phase conversion. The arrangement has a space including a working gas and is arranged to include a generated standing sound wave, whereby said sound wave is generated such that the sum of added and consumed wave energy is greater than or equal to zero. Furthermore, the arrangement has a valve mechanism for provision and outflow of a quantity of a working gas or composition, including at least one substance, in the space and is arranged to work synchronously with the generated sound wave. The generated sound wave exposes the working gas or composition to pressure and temperature changes, whereby a gas compression creates an elevated temperature and a gas decompression creates a reduced temperature; and whereby a phase conversion, caused by the pressure and temperature changes, is obtained.
Abstract: The present invention encompasses an arrangement adapted for energy transformation under the utilisation of an oscillating gas volume gathered in a space, where the reciprocal oscillating movement of the gas volume within said space is sustained by an energy supplying device and where a gas compression caused by the oscillation makes for the creation of an elevated temperature within all or parts of said gas volume and where a gas decompression caused by the oscillation makes for the creation of reduced temperature within all or parts of said gas volume. There are connected to said space one or more first valve-related means, where said first valve-related means is controllably actuable by a control unit in order to supply or extract to or from said space thermal energy during a compression stage for said gas volume.
