Soybean thermal energy storage

Can soybean wax cooling system reduce PV temperature?

The experiment show that PV applied with soybean wax as a passive cooling system can reduce the maximum PV temperature at 1100 W/m2 intensity from 60.7℃ to 54.7℃ and increase its maximum efficiency by 0.42% at 900 W/m2 intensity. Soybean wax cooling system has proven to be effective in reducing PV temperature.

What is the thermal conductivity of soy wax?

The thermal conductivity of soy wax increased with the ratio of pure soy wax and nano-soy wax; the thermal conductivity was 6.01 for soy wax+graphene and 5.71 for soy wax+Ti3AlC2. Differential scanning calorimetry (DSC) results showed an increase in the melting and solidifying points of pure soy wax.

What is thermal energy storage?

Thermal Energy Storage (TES) has been widely used to address fluctuations in energy demand and supply gaps. There are three forms of TES: Latent Heat Thermal Energy Storage (LHTES), Sensible Heat Thermal Energy Storage (SHTES), and thermochemical storage systems (Nomura et al., 2015).

Does soy wax have a thermal cycle?

In a study conducted by (Trisnadewi et al., 2021), pure soy wax thermal cycle test results were obtained. Thermal cycling tests were performed with heating and cooling cycles of 0, 500, 1000, 3000, and 5000.

What is the absorption peak of soy wax?

Soy wax has an absorption peak in 1702–1738 cm-1, which indicates the absorption of the strain vibration of the carboxylate group (C=O). After synthesizing the spectra of the PCM samples, soy wax+graphene (Figure 2 (b)) and soy wax+ Ti3AlC2 (Figure 2 (c)) show similar peak spectra to those of pure soy wax.

Does PCM soy wax conduct heat?

The presence of carbon and aluminum in PCM soy wax can increase the thermal conductivity of the material, increasing the ability of PCM soy wax to conduct heat. Based on the EDS test, the carbon value of MAXene can approach the carbon content in graphene, namely 82.2 wt.% in Ti3AlC2 and 84.49 wt.% in graphene.
