Whereas inorganic salt hydrates are typical inorganic phase change materials suitable for the temperature range of 0-150°C, their investigation and applications on thermal energy storage have received more and more during the recent years. A review on investigation progress and applications of their phase transition temperature control and adjustment was made in this paper, which is of important reference and practical value for understanding and predominating the investigation and engineering applications on their phase transition temperature control and adjustment.

Thermal Energy Storage Systems

Phase change materials (PCMs) are significant in terms of applicability for the thermal energy storage (TES). Thanks to the high thermal storage density and wide range of phase transition temperature they are promising storage mediums for a large number of applications. PCMs can be used to support efficient use of waste or excess heat. Selection of adequate material as well as design of optimal TES magazine are crucial. It is important to choose material which is characterized by suitable temperature range of phase transition, possibly high latent heat of transition, specific heat and thermal conductivity. Also important features are: ability to work properly after many operation cycles, minimum volume change and gas generation during the phase transition. It is also advantageous when PCM is non-toxic and non-corrosive, non-flammable, non-explosive, environment friendly and easy to recycle. Even the best designed PCMs would not be able to store heat efficiently if the whole magazine and its construction were not good enough. This is the reason why a lot of effort is taken to design effective TES system. The aim of this work is to analyse examples of different configurations of PCM – based thermal energy storage systems. Authors compare selected TES systems and discuss their characteristics.

Application Fields

The desired phase-transition temperature and enthalpy of phase change materials are different in different application fields. When the composite way is reasonable, the phase-transition temperature and enthalpy of phase change can satisfy the demand of PCMs using in clothes. Based on The theory of eutectic system and the Schroeder Formula, the lowest eutectic point was computed by using MATLAB software in this paper, and then the enthalpy of phase change was also compared in order to get the best proportion of PCMs.

Energy Storage Properties

Phase-change materials (PCMs) are essential modern materials for storing thermal energy in the form of sensible and latent heat, which play important roles in the efficient use of waste heat and solar energy. In the development of PCM technology, many types of materials have been studied, including inorganic salt and salt hydrates and organic matter such as paraffin and fatty acids. Considerable research has focused on the relationship between the material structure and energy storage properties to understand the heat storage/emission mechanism involved in controlling the energy storage performance of materials. In this study, we review the application of various carbon-filled organic PCMs in the field of heat storage and describe the current state of this research.
