“…PCMs and their thermal properties suitable for air-conditioning applications can be found in [76]. For air-conditioning and refrigeration (ice storage), temperatures from −5 to 15 • C are optimum for thermal storage [8,[83][84][85], but at lower temperatures, latent heat storage materials are better than sensible heat storage materials (like water). Some of the commercially available PCMs for cold storage are shown in Table 10.…”

Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that provide a way of valorizing solar heat and reducing the energy demand of buildings. The principles of several energy storage methods and calculation of storage capacities are described. Sensible heat storage technologies, including water tank, underground, and packed-bed storage methods, are briefly reviewed. Additionally, latent-heat storage systems associated with phase-change materials for use in solar heating/cooling of buildings, solar water heating, heat-pump systems, and concentrating solar power plants as well as thermo-chemical storage are discussed. Finally, cool thermal energy storage is also briefly reviewed and outstanding information on the performance and costs of TES systems are included.

“…But PCM should not be thicker than a certain amount since otherwise not all the thickness has the chance to undergo phase change [24]. In such a case, PCM is partially melted/frozen which reduces its effectiveness.…”

“…However, applying the load leveling storage strategy caused that the overall energy usage was reduced up to 4% lower than the non-storage system. Azzouz [12], [13] carried out experimental tests to investigate the performance of a household refrigerator using a PCM. Accordingly, the CTES can keep the system in the allowed range of temperature for 9 hours and there is no need to the compressor during this period.…”

“…In Table, I list of main applicable eutectic PCMs which can be used in sub-zero temperature range is provided. For investigating CTES system in this paper, NaCl-H2O is selected as PCM, because of the operating temperature of household freezers (250 to 260 K) [2], [12], [13], and its stability, high heat capacity, low cost and also its safety. In Table II, the chosen PCM's thermophysical properties are reported.…”

Abstract-Freezer is one of the electrical components that can be found in any building. Like any electrical appliance domestic freezer consumes a significant amount of energy during its working time. During recent decades a lot of solutions have been found to reduce this energy consumption. One of the most usable and appropriate ones is implementation of phase change material (PCM) in a Cold Thermal Energy Storage (CTES) system which can be installed in a household freezer. In this paper numerical investigation of using CTES system in a domestic freezer in order to diminish energy consumption during pick hours (18-22:30), is studied. Regard to the temperature ranges of the freezer, NaCl-H2O is used as a PCM in the CTES system. In a distinct period of time, a large amount of cold thermal energy in latent heat form is stored at low temperature in the PCM, and it is released in the freezer's cabin when the compressor is off. Accordingly, numerical modeling and simulation using Computational Fluid Dynamics (CFD) software on charging and discharging cycle of PCM are done to measure cold storage period and amount of saved energy. The results reveal that using CTES could keep the freezer in the standard thermal condition without using a compressor, for 4.5 hours. These results show that if the PCM used in CTES system for a year, it could reduce energy, fossil fuel consumption and CO2 emission up to 45.7 kWh, 13.7 liters and 32.0 kg, respectively.
