Abstract: A latent heat storage system includes at least one latent heat storage device which contains a storage medium with latent heat, at least one heat pump coupled to the latent heat storage device, at least one extraction circuit which has a first heat carrier medium and with which, during normal operation, in accordance with the intended purpose, heat can be extracted from the storage medium and supplied to the heat pump on the input side, and an extraction heat exchanger which is in contact with the storage medium, wherein the extraction heat exchanger is connected to the extraction circuit. Between the extraction heat exchanger and the heat pump, a coupling device is arranged in a connection line, which at least temporarily supplies a second heat carrier medium, which can be heated by at least one heat source, into a section of the connection line. A method for operating a latent heat storage system is also provided.

Abstract: A latent heat storage system includes at least one latent heat storage device which contains a storage medium with latent heat, at least one extraction circuit by means of which, in accordance with the intended purpose, heat can be extracted from the storage medium, and at least one regeneration circuit by means of which, in accordance with the intended purpose, heat can be supplied into the storage medium. The at least one latent heat storage device includes at least one extraction heat exchanger which is in contact with the storage medium and can be connected to the extraction circuit, and at least one regeneration arrangement within the storage medium, which can be connected to the regeneration circuit. A coupling device is provided, by which the at least one extraction heat exchanger can be at least temporarily coupled to the at least one regeneration arrangement for common heat extraction from the storage medium or for common heat supply into the storage medium.
