Benefits of technology

The invention is a coupling that allows for better heat transfer between two objects during operation. This coupling can help to cool down faster or meet increased cooling demands more effectively. It can also allow for faster regeneration of the heat storage device by supplying more heat. This makes it possible to cool efficiently in midsummer and requires less cooling in full-load operation. The coupling can open maximally in this operating mode, providing quick response time.

Problems solved by technology

The hydraulic circuits for the extraction and for the regeneration have to be strictly separated in order to avoid an uncontrolled thawing or freezing, which makes the ice storage device uncontrollable and in the most disadvantageous case can damage or even destroy the heat exchanger pipes due to the chipping off of ice.

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. A corresponding operating method is also provided.

Description

BACKGROUND AND SUMMARY[0001]The invention relates to a latent heat storage system having a latent heat storage device and to a method for operating a latent heat storage system.[0002]From EP 2614330 A1, an ice storage system is known, in which an extraction heat exchanger extracts heat from an ice storage device during the healing period, until the ice storage device is thermally unloaded. During the thermal unloading, a predetermined volume around die extraction heat exchanger has completely solidified into ice. This occurs in a controlled manner. The water around the heat exchange pipes of the extraction heat exchanger solidifies in a targeted manner from the inside to the outside. In order to reload the ice storage device, after the heating period, heat is introduced into the ice storage device via a regeneration heat exchanger. In the process, the ice around the extraction heat exchanger likewise thaws again in a targeted and directed manner. The hydraulic circuits for the extra...
