The invention relates to a cold and/or heat accumulator comprising a first heat exchanger and preferably a second heat exchanger. The first heat exchanger may, in particular, be provided to be perfused by a refrigerant while the second heat exchanger is preferably perfused by brine. The first heat exchanger and preferably also the second heat exchanger are engaged in a heat-exchanging relationship with carrier elements charged with a cold or heat storage medium and may, in particular, be formed by graphite strips. The cooling energy and/or heat accumulator according to the invention exhibits a good heat conduction, short charging times, a high cooling or heating performance, low pressure losses as well as a good cooling agent distribution. Further its integration options are manifold due to the selected fixation means.
