“…Table 3 displays some frequently used materials for sensible TES. Water is the most widely used TES medium due to its cheap price and favourable thermal properties [74]. supply, it also significantly levels out peak load in DHC system as energy produced during off-peak hours can be used for peak hours.…”

Optimization and Enhancement of DHC networks to reduce (a) fossil fuel consumption, CO 2 emission, and heat losses across the network, while (b) increasing return on investment, forming key challenges faced by decision makers in the fast developing energy landscape. While the academic literature is abundant of research based on field experiments, simulations, optimization strategies and algorithms etc., there is a lack of a comprehensive review that addresses the multi-faceted dimensions of the optimization and enhancement of DHC systems with a view to promote integration of smart grids, energy storage and increased share of renewable energy. The paper focuses on four areas: energy generation, energy distribution, heat substations, and terminal users, identifying state-of-the-art methods and solutions, while paving the way for future research.

“…They concluded that the critical value for the case of a 25/75 % mixture of hexadecane in water was found to be 680 ppm. Tetradecane and hexadecane binary mixtures with different concentration were used to make PCS, and thermal properties include freezing point, the heat of fusion, thermal stability and volume expansion during the phase change process were investigated and the results showed that these materials were attractive candidates as potential PCMs for cool storage in district cooling system [109].…”

The use of latent heat storage, microencapsulated phase change materials (MEPCMs), is one of the most efficient ways of storing thermal energy and it has received a growing attention in the past decade. However, there is no complete overview of its utilisation in thermal energy storage systems, and the information is widely spread in the literature. In this paper, a comprehensive review has been carried out for MEPCMs. Four aspects have been the focus of this review: fabrication and characterization of MEPCMs, applications of MEPCMs to the textile and building, fundamental properties of microencapsulated phase change material slurry (MPCS) and application of MPCS to the thermal energy storage system. Over 140 recent publications are referenced in this paper.

“…Choi et al 7 determined the heat of fusion and melting point of alkane mixtures by calculating the melting temperature depression constant using DSC calorimeter. Bo et al 8 studied the various thermal properties of tetradecane and hexadecane binary mixtures for cooling applications. Thermal storage characteristic of paraffin (mainly nonadecane) as microencapsulated phase change material was reported by Zhang et al 9 among others.…”

The present work aims to investigate the phase transition, dispersion and diffusion behavior of nanocomposites of carbon nanotube (CNT) and straight chain alkanes. These materials are potential candidates for organic phase change materials(PCMs) and have attracted flurry of research recently. Accurate experimental evaluation of the mass, thermal and transport properties of such composites is both difficult as well as economically taxing. Additionally it is crucial to understand the factors that results in modification or enhancement of their characteristic at atomic or molecular level. Classical molecular dynamics approach has been extended to elucidate the same. Bulk atomistic models have been generated and subjected to rigorous multistage equilibration. To reaffirm the approach, both canonical and constant-temperature, constant- pressure ensembles were employed to simulate the models under consideration. Explicit determination of kinetic, potential, non-bond and total energy assisted in understanding the enhanced thermal and transport property of the nanocomposites from molecular point of view. Crucial parameters including mean square displacement and simulated self diffusion coefficient precisely define the balance of the thermodynamic and hydrodynamic interactions. Radial distribution function also reflected the density variation, strength and mobility of the nanocomposites. It is expected that CNT functionalization could improve the dispersion within n-alkane matrix. This would further ameliorate the mass and thermal properties of the composite. Additionally, the determined density was in good agreement with experimental data. Thus, molecular dynamics can be utilized as a high throughput technique for theoretical investigation of nanocomposites PCMs.
