The device (5) has a rigid pressure cylinder (55) for a refrigeration medium (16) enclosing a balloon (2), inflated and deflated via controlled supply and venting of a gas/liquid filling medium (26), with an internal space which is hermetically sealed relative to the refrigeration medium. The variation in the volume of the balloon is used for altering pressure in the residual volume (3) for liquefying refrigeration medium. The cylinder has an associated cooling device and/or filling medium for the balloon acting simultaneously as a heat transfer medium with heat exchange via the balloon wall. Also included are Independent claims for the following: (a) a method for providing heat or cold via a thermodynamic refrigeration or heat pump process; (b) a heat pump method
