Increasing energy consumption in residential and public buildings requires development of new technologies for thermal energy production and storage. One of possibilities for the second listed need is the use of phase change materials (PCMs). This work is focused on solutions in this area and consists of two parts. First one is focused on different designs of thermal energy storage (TES) tanks based on the phase change materials. The second part is the analysis of tests results for TES tank containing shelf and tube heat exchanger and filled with phase change material. Thermal energy storage tank is analyzed in order to use it in domestic heating and hot utility water installations. The aim of this research was to check the applicability of phase change material for mentioned purpose. Results show that using phase change materials for thermal energy storage can increase amount of stored heat. The use of properly selected PCM and heat exchanger enables the process of thermal energy storing and releasing to become more efficient.

Phase change materials (PCM) have recently received considerable attention in the field of thermal energy storage, due to their intrinsic properties. Phase change material slurry is a novel medium of heat storage and transfer, its apparent specific heat and heat transfer capacity is better than water.PCM slurries are being investigated for active thermal energy storage or as alternatives to conventional single phase fluids because they are pumpable and have advanced heat transport performance with phase change. This review mainly presents the information on PCM emulsions and microencapsulated PCM slurries (mPCM slurries).

Thermal energy storage (TES) based on hidden heat concept is good substitute for sensible heat storage because of its dense storage capacity and almost constant temperature heat transfers during the charging and discharging cycle. During no load and low cooling load conditions the system stores the thermal energy in the storage medium (phase change material) which will be used latter to meet the requirement in off cycle conditions. The intention of present work is to increase the system off cycle time, maintain required temperatures during power cuts by joining a few inch thick layer of phase change material on the outer surface of the evaporator. For investigation purpose a deep freezer which runs on vapor compression system of 50 liters storage capacity is fabricated with and without phase change materials. The eutectic compositions nearly 23 wt% salt (NaCl) dissolved in water and aluminium nitrate around 26 wt% dissolved in water are used as phase change materials. By the end of all experimental investigations it was noticed that the off cycle time system with phase change material is increased by 5.5 hours compared to system without phase change material, food storage time is enhanced by 8 to 14 hrs and a little power saving also achieved.

Abstract Microencapsulation is a viable technique to protect and retain the properties of phase change materials (PCMs) that are used in thermal energy storage (TES) applications. In this study, an organic ester as a phase change material was microencapsulated using melamine–formaldehyde as the shell material. This microencapsulated PCM (MPCM) was examined with cyclic cryogenic treatment and combined cyclic cryogenic heat treatment processes. The surface morphology studies showed that the shell surfaces had no distortions or roughness after cryogenic treatment. The cryogenically conditioned microcapsules exhibited diffraction peak intensity shifts and crystal structure changes. The onset of melting for the nonconditioned and conditioned microcapsules were measured to be 8.56–9.56 °C, respectively. Furthermore, after undergoing the cryogenic and heat treatment processes, the PCM microcapsules had appreciable latent heat capacities of 39.8 kJ/kg and 60.7 kJ/kg, respectively. Additionally, the microcapsules were found to have good chemical stability after the cryogenic treatment. In addition, the cryogenically conditioned microcapsules were found to be thermally stable up to 128.9 °C, whereas the nonconditioned microcapsules were stable up to 101.9 °C. Based on the test results, it is obvious that the cryogenically conditioned microcapsules exhibited good thermal properties and are very desirable for cool thermal energy storage applications.
