Abstract:
Objectives: This research aims to improve the energy efficiency and performance of traditional refrigerators by integrating Phase Change Material (PCM) and Nano-Enhanced Phase Change Material (NEPCM) on the condenser. Methods: This research integrated paraffin wax as phase change material and Titanium dioxide (TiO2) nanoparticle enhanced phase change material as Nano enhanced phase change material on the condenser side and evaluated their effects on the coefficient of performance (COP), Energy Efficiency, and Temperature regulation through experimental analysis. Findings: The results demonstrate that the integration of PCM increases the coefficient of performance (COP) by 21%, while the NEPCM achieves a 36% improvement. PCM integration reduces the condenser mid-temperature by 1°C, and NEPCM further lowers it by 2.5°C due to the enhanced thermal conductivity of TiO2 nanoparticles. Energy savings are significant, with PCM providing up to 10% savings and NEPCM achieving up to 21%, indicating a clear improvement in energy efficiency. Novelty: The research demonstrates significant energy efficiency improvements using NEPCM, providing measurable results to validate the enhanced thermal conductivity of TiO2 nanoparticles. Keywords: Domestic refrigerator, Energy Efficiency, Nano­particle enhanced Phase Change Material, Phase Change Material, Titanium Dioxide Nanoparticles

Abstract:
The augmentation of fresh water and increase in the solar still efficiency of a triangular pyramid is added with phase change material (PCM) on the basin. Experimental studies were conducted and the effects of production of fresh water with and without PCM were investigated. Using paraffin as the PCM material, performance of the solar still were conducted on a hot, humid climate of Chennai (13°5′ 2" North, 80°16′ 12"East), India. The use of paraffin wax increases the latent heat storage so that the energy is stored in the PCM and in the absence of solar radiation it rejects its stored heat into the basin for further evaporation of water from the basin. Temperatures of water, Tw, Temperature of phase change material, TPCM, Temperature of cover, Tc were measured using thermocouple. Results show that there is an increase of maximum 20%, in productivity of fresh water with PCM. Keywords: fresh water production; PCM; thermal energy storage; phase change material

Abstract:
Thermal energy storage with phase change materials (PCMs) has attracted a lot of attention in the last several decades. Most PCMs do not change phase at a constant temperature but rather in a certain temperature range. It means that the PCM need to transit through its phase change temperature range to fully change phase from the solid state to the liquid state and vice-versa. The situation, in which the phase transition begins and/or ends within the phase change temperature range (in the mushy zone), is usually called a partial phase transition (or a partial phase change). The partial phase transitions occur quite often in real-life thermal energy storage systems with PCMs; especially when a PCM has a wide phase change temperature range. The behavior of PCMs during the partial phase transitions is poorly understood at the moment, because the experimental techniques used for the characterization of PCMs (such as the differential scanning calorimetry – DSC) are difficult to apply for the study of partial phase transitions. The lack of knowledge in this area influences the accuracy of phase change simulation models. The main goal of the experimental investigations, described in the paper, was to obtain data for the development of a simulation model for partial phase changes. The experimental set up for the investigation of partial phase changes of PCMs has been proposed, assembled, and the pilot measurements have been conducted. The experimental set up consists of two water storage tanks (that can be maintained at different water temperatures), a water-PCM concentric tube type heat exchanger and a data acquisition system. The water flows through the central tube of the heat exchanger while the PCM is located in the annular space of the exchanger. The water storage tanks, maintained at the temperatures within the phase change temperature range of a PCM, allow for the investigations of the heat storage cycles consisting of partial phase changes.

The main influencing factor of roof slope in the phase change roof was analyzed in this paper. The results show that, increasing the roof slope is beneficial to promote the effect of heat-insulating and temperature-reducing of phase change roof, whereas the extent of the ascension is weak. Different slopes in roof structure have basically no influence on the delay effect.

Abstract:
Almost all stones on a lane will become glassy if they are melted and quenched. They will become transparent and quite different in appearance from before vitrification. This visible change constitutes the recording of information. We might refer to the stone as “1 bit.” If the vitrified stone is subsequently kept at a high temperature under its melting point, it will lose its transparency and turn back to the appearance it had before melting and quenching. Thus the “1 bit” is erased. This is the simple mechanism of an erasable phase-change optical memory. In practical systems, a laser beam focused into a diffraction-limited spot is used for recording. This enables the spatial size of the “1 bit” to be very small (of submicron order) so that the recording density is very high.Figure 1 shows a transmission-electron-microscope (TEM) photograph of an actual optical disk. The elliptical smooth areas are recording marks in the amorphous state that were formed by high-power and short-duration laser irradiation. The shortest mark length is about 0.5 μm. The area surrounding the amorphous marks is in the crystalline state and consists of small grains. The two states differ from each other in optical properties such as refractive indices and optical absorption coefficients. Accordingly when the bits are illuminated with low-intensity laser light, the reflected light from the amorphous and crystalline regions is different and may be detected as information signals.The amorphous marks are erased by heating above the glass-transition temperature by laser irradiation, but with lower power than is used in the case of recording.

Abstract:
In this paper, thermal performance of various phase change materials (PCMs) used as thermal energy storage in a solar cooker has been investigated numerically. Heat conduction equations in cylindrical domain are used to model heat transfer of the PCMs. Mathematical model of phase change problem in the PCM storage encompasses heat conduction equations in solid and liquid region separated by moving solid-liquid interface. The phase change problem is solved by reformulating heat conduction equations with emergence of moving boundary into an enthalpy equation. Numerical solution of the enthalpy equation is obtained by implementing Godunov method and verified by analytical solution of one-dimensional case. Stability condition of the numerical scheme is also discussed. Thermal performance of various PCMs is evaluated via the stored energy and temperature history. The simulation results show that phase change material with the best thermal performance during the first 2.5 hours of energy extraction is shown by erythritol. Moreover, magnesium chloride hexahydrate can maintain temperature of the PCM storage in the range of 110-116.7°C for more than 4 hours while magnesium nitrate hexahydrate is effective only for one hour with the PCM storage temperature around 121-128°C. Among the PCMs that have been tested, it is only erythritol that can cook 10 kg of the loaded water until it reaches 100°C for about 3.5 hours.Article History: Received June 22nd 2016; Received in revised form August 26th 2016; Accepted Sept 1st 2016; Available onlineHow to Cite This Article: Tarwidi, D., Murdiansyah, D.T, Ginanja, N.

Abstract:
In the last few years, a controversy has been raised regarding the nature of the chemical bonding present in phase change materials (PCMs), many of which are minerals such as galena (PbS), clausthalite (PbSe), and altaite (PbTe). Two opposite bonding models have claimed to be able to explain the extraordinary properties of PCMs in the last decade: the hypervalent (electron-rich multicenter) bonding model and the metavalent (electron-deficient) bonding model. In this context, a third bonding model, the electron-deficient multicenter bonding model, has been recently added. In this work, we comment on the pros and cons of the hypervalent and metavalent bonding models and briefly review the three approaches. We suggest that both hypervalent and metavalent bonding models can be reconciled with the third way, which considers that PCMs are governed by electron-deficient multicenter bonds. To help supporters of the metavalent and hypervalent bonding model to change their minds, we have commented on the chemical bonding in GeSe and SnSe under pressure and in several polyiodides with different sizes and geometries.

Abstract:
Ultrafine phase change nanofibers based on polyethylene glycol 1000 (PEG1000) as phase change material (PCM) and polyamide 6 (PA6) as a supporting material were prepared in a systematic manner planned by the Design-Expert® software using the uniaxial electros-pinning. Research surface methodology (RSM) was carried out to optimize the parameters and conditions leading to minimize the fiber diameter. The effect of PEG content, applied voltage, needle gauge, and flow rate on the fiber characteristics was studied by a central composite design (CCD). The minimum diameter of nanofibers was predicted by a quadratic model to be 64.33 nm and the actual fibers diameter prepared under optimal condition showed a very low relative standard error (RSE). It was shown that the PEG/PA6 mass ratio has the dominant effect on the fibers diameter. The results from FTIR and FE-SEM images confirmed well encapsulated PEG in PA6 and no leakage and morphology alterations were observed after heating tests. To further investigate morphological structure and the quality of PEG1000 encapsulation in PA6 matrices, the composite fibers underwent a solvent treatment using ethanol. The results proposed a new innovative method to control operational electrospinning conditions for encapsulating phase change materials in polymer matrices which is very important in thermal energy saving/retrieving applications.
