The highest thermal energy storage in these materials occurs during the phase change process. Accurate analysis of the PCMs behavior will result in the optimal use of these materials. In this paper, the performance of a shell and tube heat exchanger containing PCMs is analyzed using the modeling results of PCMs.
To speed up the design process of thermal energy storage devices, it is critical to develop fast and accurate modeling methods for phase change material embedded heat exchangers (PCM HXs). This study developed and compared two approximation-assisted reduced-order PCM HX models for the simulation of thermal storage
To model heat transfer from natural convention within the tank when a temperature inversion occurs between nodes, the conduction term is modified based on Equation 4 when a temperature inversion
An air-soil heat exchanger (ASHE) is a geothermal system that uses the thermal inertia of the soil to heat or cool part of the air to renew a habitat. It is sometimes
It is widely understood that facilities for storing very large amounts of electric energy are key to any long-term plan to supplant fossil fuel with renewable energy. 1–3 The desirability of switching to renewable sources is, of course, controversial, and it is not clear that eliminating fossil fuel is economically feasible at this time. 4–7 But without storage, it
In this study, the energy-storage based heating and defrosting performances of an air source heat pump system with a micro-channel heat exchanger as its outdoor coil were experimentally investigated. The impacts of energy storage on system heating and defrosting performances were quantitatively analyzed and discussed with

The schematic diagram of counterflow heat exchanger is shown in Fig. 2, that is, plate heat exchanger.Air and water or thermal oil are flowing among different plates to exchange heat. In this paper, the NTU of heat exchanger is
To validate the mathematical model, the heat exchanger costs of OHE as a function of the waste heat temperature below 200 in present calculation are compared with that in the
Abstract. In this paper, an optimization method is proposed to improve the performance of a novel heat exchanger with latent heat thermal energy storage. Paraffin/expanded graphite composites were used as phase change material filled in annular tube, maintained contact with the shell and tube flow channels simultaneously.
Besides their role in balancing the electric grid, energy storage systems may provide also several other useful services, such as price arbitrage, stabilizing conventional generation, etc
This paper focuses on the assessment of a heat and mass exchanger dedicated to an absorption/desorption seasonal thermal energy storage system.

Abstract. The performance of a lab-scale concrete thermal energy storage (TES) module with a 2-kWh thermal capacity is evaluated at temperatures up to 400 °C. The TES module uses conventional normal weight concrete with thermal and mechanical properties that are tailored for use as a solid thermal energy storage media.
These results also showed that ASHE responds favorably to Ouagadougou meteorology. In 2017, B. Kaboré et al. [24] showed that a nodal approach is effective for the study of air-soil heat
The use of air-soil heat exchangers for cooling habitats has developed considerably in recent years. An air-soil heat exchanger (ASHE) is a geothermal system that uses the thermal inertia of the soil to heat or cool part of the air to renew a habitat. It is sometimes called a Canadian well or a Provencal well. In this present work, we have
