A heat pump system includes a regenerative thermal machine () in fluid communication with one or more heat reservoirs (), wherein the regenerative thermal machine () comprises working fluid compression () and expansion () spaces; and an electrical machine () that is electrically connectable via interconnector () to an electricity distribution grid (); characterised in that the regenerative thermal machine () further comprises a phase change means () operable to change the phase relationship between the said working fluid compression () and expansion spaces () of the regenerative thermal machine ().

Heat pump system and a method of operating a heat pump system

A thermodynamic machine () of a Stirling type, the machine comprising an expansion chamber (), a compression chamber (), a regenerator () disposed between the expansion and compression chambers; a first heat exchanger () in communication with the expansion chamber and the regenerator; a second heat exchanger () in communication with the compression chamber and the regenerator; a first bypass conduit () connecting the expansion chamber with the regenerator bypassing the first heat exchanger; a second bypass conduit () connecting the compression chamber with the regenerator bypassing the second heat exchanger; at least a pair valves (), one valve () provided between the expansion chamber and the first heat exchanger and/or between the regenerator and the first heat exchanger and/or in the first bypass conduit between the expansion chamber and the regenerator; and the other valve () provided between the compression chamber and the second heat exchanger and/or between the regenerator and the second heat exchanger and/or in the second bypass conduit between the compression chamber and the regenerator; the valves being controllable.

Thermodynamic machine

A method of analyzing seismic survey data in which a transfer function for a geological model is derived by ray tracing techniques applied to theoretical data and the transfer function is applied to actual survey data in order to calculate reflection points () and/or other attributes for each shot ()/receiver () pair. The number of ray tracing calculations which have to be performed in deriving the model transfer function can thus be controlled. A sufficiently accurate transfer function can be derived using theoretical data representing substantially fewer shot ()/receiver () pairs than are used in the traditional ray tracing solution applied directly to actual survey data. Attribute values for actual source ()/receiver () pairs are estimated by interpolating the transfer function data.
