9. An apparatus, comprising:
a closed gas system with a working circuit, in which a compressor for a working fluid, a first heat exchanger for heating the working fluid, an expander and a second heat exchanger for cooling the working fluid are arranged;
a first pressurized gas tank and a first gas line, which branches off from the working circuit downstream of the compressor and upstream of the first heat exchanger and opens into the first pressurized gas tank, and a second gas line, which branches off from the first pressurized gas tank and opens into the working circuit downstream of the expander and upstream of the second heat exchanger; and
a fourth heat exchanger which is arranged in the second gas line.
