“…This field could bring exciting opportunities in the area of thermal computing [ 8,9,265–267 ] and energy management, conversion and storage. [ 268,269 ] A general comparison of fluidic and mechanical TCD with solid‐state devices is shown in Table S1 in Supporting Information. Future studies of fluidic and mechanical TCDs should verify promising numerical results through experiments, produce devices with different dimensions and different geometries, and discover new operation principles and materials for increasing the switching (rectification) ratio and decreasing the switching (response) time.…”

In recent years, intensive studies on thermal control devices have been conducted for the thermal management of electronics and computers as well as for applications in energy conversion, chemistry, sensors, buildings, and outer space. Conventional cooling or heating techniques realized using traditional thermal resistors and capacitors cannot meet the thermal requirements of advanced systems. Therefore, new thermal control devices are being investigated to satisfy these requirements. These devices include thermal diodes, thermal switches, thermal regulators, and thermal transistors, all of which manage heat in a manner analogous to how electronic devices and circuits control electricity. To design or apply these novel devices as well as thermal control principles, this paper presents a systematic and comprehensive review of the state‐of‐the‐art of fluidic and mechanical thermal control devices that have already been implemented in various applications for different size scales and temperature ranges. Operation principles, working parameters, and limitations are discussed and the most important features for a particular device are identified.

“…Storage is the key technology to establish an efficient coupling between energy sources and generation, conversion or distribution system, was well as between such energy systems and their particular end-use applications, thus allowing for a smart thermal management. 1 In the building sector, the urge towards Zero Energy Buildings impels alternative heating and cooling systems that require minimum energy consumption. Thermal energy storage (TES) can favour a more efficient use of energy if implemented either upstream of the building heating and cooling delivery systems 2 or directly integrated within the very building structure, being the latter sometimes referred as building integrated thermal energy storage (BITES).…”

Thermally activated building systems (TABS) constitute an energy efficient building conditioning solution through the combination of low-exergy space heating and cooling and thermal energy storage (TES) features. Their implementation is, however, complex, due to the number of factors involved in their design and operation. Mathematical models are useful to overcome this, but require validation, while experimental setups to study sensible TES can be bulky and difficult to handle. In this work, a homogeneous concrete slab and a multilayer concrete-sand-gravel slab are built and activated with constant heat flow. Both slabs are experimentally tested and their thermal behaviour is modelled through a 1D finite difference method (FDM). Results demonstrate that materials such as sand and gravel can be used to provide relevant experimental data for TABS heat transfer model validation through a versatile lab test rig. A 1D FDM proves to be a simple, accurate method to predict the thermal behaviour of the slabs during transient peaks in charging and discharging processes as well as during steady-state operation, given that most of the time absolute errors remain below the measurement uncertainty thresholds. Finally, this paper sets a basis to support future experimental work on sensible TES and provides data for further model validation.

“…Furthermore, the heat storage density that is normally associated with the latent heat of crystallization and/or melt is 5 to 14 times larger than in systems utilizing sensible heat. Congruent melting is also desirable for the consistent storage and release of energy without phase segregation and loss of enthalpy during PCM usage …”

“…Congruent melting is also desirable for the consistent storage and release of energy without phase segregation and loss of enthalpy during PCM usage. [1][2][3] Currently, most of the PCMs in use commercially are derived from petroleum feedstock (ie, paraffin) and inorganic salts. Of these, paraffin accounts for approximately 45% of all PCMs used.…”

Lipid‐derived monoamide as phase change energy storage materials

et al. 2019

Summary One of the major shortcomings of current organic phase change materials (PCMs) is their relatively low melting points, typically below 80°C, which limits their integration into thermal energy storage (TES) systems. The present work was aimed at developing lipid‐derived PCMs with increased melting points which would be suitable for TES applications requiring higher melting points without compromising other key properties such as enthalpy. The introduction of an amide group into the structure of linear saturated fatty acids was used as a means to increase intermolecular interactions and therefore crystallization and melting points. A series of six linear monoamides with differing chain length and symmetry about the amide group were investigated for thermal stability, thermal transition, flow behavior, and crystal structure to establish the structure‐property relationships relevant to TES. The presence of the highly polar amide group in the aliphatic fatty acid–derived molecules resulted in notable improvement in performance compared with the analogous monofunctional molecules: Increases in melting points (79°C‐96°C) and high enthalpies of fusion (155‐201 J/g) were recorded. Fundamental relationships between structure, processing, and macroscopic physicochemical properties, never before elucidated, were revealed in the study. The study revealed a step‐like variation of macroscopic properties: a surprising outcome of the competition between intermolecular attractions, symmetry effects, and mass transfer limitations. The predictive structure‐function relationships established in this work will allow the straightforward engineering of monoamide architectures that can extend the range of organic PCMs and deliver thermal properties desirable for TES applications.
