“…Hence, hydrate-based refrigeration, which uses gas hydrate slurries as the primary refrigerant, has great potential to improve the coefficient of system performance by being pressured and condensed separately to decrease the energy consumption of the compressor. The number of publications on relative technologies, e.g., the design and integration of key components [70] and multi-stage processes and the optimization of operation strategies [71] is still limited.…”

Phase change slurries (PCSs) have great potential as both a heat transfer fluid and an energy storage medium for cooling processes, cold energy storage, and cold energy transportation due to desirable thermophysical properties. One of the major benefits of PCSs compared to pure phase change materials is their fluidity, thus making them cooled or heated by a heat exchanger, pumped through pipes, discharged, and stored directly in a thermal energy storage tank. The use of encapsulated phase change slurries and gas hydrate slurry has thus attracted considerable interest as reflected in the literature with a rising number of publications and institutions involved in the area. The use of bibliometric techniques has found a recent interest in the literature to define the progress of different scientific topics and inspire researchers to identify novelties. In this paper, bibliometric analysis and a detailed systematic review are carried out to show the state-of-the-art development of PCSs for cooling applications. Research gaps and hotspots are identified to help define future perspectives on this topic.

“…A clathrate hydrate is a cage crystal formed by the host water molecule wrapping the guest molecule . The formation and dissociation process of a hydrate involves a large amount of heat changes, and based on this characteristic, the hydrate cold storage and hydrate refrigeration technology have been developed currently. − The coefficient of performance of the hydrate-base refrigeration system formulated by the thermodynamic state functions can reach 18.66 . Hydrate guest molecules display an essential role of the hydrate cold storage, whose innovation has always been the hotspot of cold storage and refrigeration research .…”

Hydrate Phase Equilibrium Data of Dimethyl Ether in the Presence of Tetrahydrofuran, Tetra-n-butylammonium Bromide, and Cyclopentane

Hydrate cold storage and refrigeration technology have a good prospect. Dimethyl ether (DME) has the characteristics of low pollution and a good refrigeration effect, which can replace freon as a refrigerant to reduce pollution due to the greenhouse effect and ozone depletion. Tetrahydrofuran (THF), tetrabutylammonium bromide (TBAB), and cyclopentane (CP) are common hydrate growth promotors. To comprehend the effect of additives on the hydrate phase equilibrium, the phase equilibrium conditions for the DME hydrate and with THF (0.095, 0.190 mass fractions), TBAB (0.160 mass fractions), or CP (0.093 mass fractions) were measured. The formation conditions of the DME hydrate are more moderate than that of the CO2 hydrate. Moreover, the addition of CP with a mass fraction of 0.093 has the best promotion effect. The results provide a basis for both cold storage technology and refrigeration technology.

The energy consumption for cooling takes up 50% of all the consumed final energy in Europe, which still highly depends on the utilization of fossil fuels. Thus, it is required to propose and develop new technologies for cooling driven by renewable energy. Also, thermal energy storage is an emerging technology to relocate intermittent low-grade heat source, like solar thermal energy and industrial waste heat as well as to exploit off-peak electricity, for cooling applications. This review aims to summarize the recent advances in thermally driven cooling and cold storage technologies, focusing on the formation and fabrication of adopted composites materials, including sorption materials, phase change materials, and slurries. Herein, first the classifications, selection criteria, and properties for these three types of materials is discussed. Then, the application potentials of all the materials are prospected in terms of economic analysis and sustainability.
