Benefits of technology

The present invention relates to a heat transfer system with a higher thermal energy density compared to previous systems. This is achieved by using a multi-phase heat transfer fluid that changes phase during heat transfer, resulting in a significantly higher latent energy contribution. The heat transfer system also uses a porous structure with a specific porosity to allow for more efficient distribution of thermal energy throughout the system. This results in a more efficient use of the heat storage unit and faster transfer of thermal energy between the two units.

Problems solved by technology

Conversely, when such material melts, it absorbs a large amount of heat for instance from the environment.
), which makes it unsuitable for thermal energy storage applications at other temperature levels.

Abstract

Passive thermal storage systems and methods comprising at least one thermal storage module for storing thermal energy in a predetermined temperature range, are disclosed. The thermal storage module comprises an FT unit and a Heat Storage (HS) unit at least partially filled with a first Phase Change Material (PCM). The HS unit comprises a container. The thermal storage module may be in the form of a stacked structure comprising the FT unit having a first wall with a first heat exchange surface and the HS unit having a second wall with a second heat exchange surface, the first and second heat exchange surfaces being in thermal contact with each other. The thermal storage system may be used to maintain the temperature of the payload of a temperature controlled container at a predetermined value or within a predetermined range.

Description

TECHNICAL FIELD[0001]The present invention relates to a thermal storage system arranged for storing thermal energy, which is for example suitable for maintaining a payload space at a predetermined temperature. The present invention further relates to a temperature controlled container comprising a thermal storage system according to the present invention.BACKGROUND ART[0002]Phase change materials (PCM) are substances that absorb and release thermal energy during the phase change. When a PCM freezes, it releases a large amount of energy in the form of latent heat at a relatively constant temperature. Conversely, when such material melts, it absorbs a large amount of heat for instance from the environment. As thermal energy carrier, PCMs are ideal for a variety of everyday applications that require temperature control. The most commonly used PCM is water / ice. Ice is an excellent PCM for maintaining temperatures at 0° C. But water's freezing point is fixed at about 0° C. (32° F.), whic...
