Determination of components for heat storage material

Abstract

Today, the world is transitioning to the 4th and 5th Generation District Heating (GDH) systems of heating networks. The main advantages of 4GDH and 5GDH are the reduction of the temperature of the coolant to +50 – +60°C and the use of various designs and operating principles of thermal energy storage. Therefore, special attention is devoted to the search for new types of coolants, heat-accumulating materials and research of their properties and determination of optimal operating modes. One of the energy storage systems that has become widespread in recent years is the mobile thermal energy storage (M-TES) that has tanks filled with heat storage material. Specially created heat storage materials are often used, which work under the necessary technological conditions and meet the strict conditions of safe transportation of liquids. This article is devoted to the search for new components for the creation of heat storage material, which will be used in capacitor-type TES together with the “thermal core”, which is created from a material with a phase transition. As a result of experimental studies of the thermocycling process of water and aqueous solutions, depending on the components added, the priority components such as guar gum and xanthan gum were chosen.
