Abstract: A pressure fluid handling system includes a closed pressure fluid circuit. The pressure fluid circuit includes, connected in series, a compressor and a pressure sink and a primary pressure fluid route from the compressor to the pressure sink and a secondary pressure fluid route from the pressure sink to the compressor. The pressure fluid handling system further includes a pressure fluid accumulator connected to the pressure fluid circuit via a first pressure fluid accumulator conduit. The first pressure fluid accumulator conduit includes a pump configured to pump pressure fluid from the pressure fluid circuit to the pressure fluid accumulator to lower the pressure levels in the pressure fluid circuit, and in that the pressure fluid handling system includes a controllable component for returning the pressure fluid from the pressure fluid accumulator to the pressure fluid circuit to increase the pressure levels in the pressure fluid circuit.
