20110243796 | ARRANGEMENT FOR ACOUSTICAL PHASE CONVERSION - 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. | 10-06-2011 |
20100281900 | ARRANGEMENT ADAPTED FOR ENERGY TRANSFORMATION - 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. There are further connected to said space one or more second valve-related means where said second valve-related means is controllably actuable by the control unit in order to supply or extract to or from said space thermal energy during a decompression stage for said gas volume. Said control unit is adapted to briefly permit actuation of said first valve-related means and said second valve-related means within mutually discrete time intervals. | 11-11-2010 |
