TL;DR
Researchers from India have simulated a new home cooling panel that combines photovoltaic power, thermoelectric cooling, and waste cooking oil as a phase change material. The system can deliver up to 15 kWh/day of cooling and has a potential payback period of around 3-4 years.
A team of researchers from India has developed a simulated model of a home cooling panel that integrates photovoltaic (PV) power generation, thermoelectric cooling, and waste cooking oil as a phase change material, demonstrating promising performance for sustainable indoor cooling.
The cooling panel is designed with a PV module on the outer layer, converting sunlight into electricity. This electricity powers a thermoelectric (TE) module that is thermally coupled to a waste palm oil-based phase change material (PCM). During the day, the PV generates power to operate the TE module, which removes heat from the PCM, storing cooling capacity. At night, when solar energy is unavailable, the PCM releases stored heat, helping to lower indoor temperatures. The system was simulated using a multi-fidelity modeling framework, combining zero-dimensional and two-dimensional models, and trained with machine learning algorithms for optimization.
Results suggest that a single panel can provide approximately 6 to 15 kWh of cooling energy per day, reduce peak indoor temperatures by up to 3°C, and shift cooling loads by about three hours. A techno-economic analysis indicates a payback period between three and four years, potentially reduced to two with incentives. Additionally, a life cycle assessment shows the panel could avoid roughly 1.2 tons of CO₂ emissions annually, utilizing about 40 kilograms of waste cooking oil.
Potential Impact on Sustainable Indoor Cooling
This development offers a low-cost, environmentally friendly alternative to conventional cooling systems, utilizing waste cooking oil as a bio-based phase change material. The integration of PV and thermoelectric technology could significantly reduce energy consumption for cooling, especially in regions with abundant sunlight. The projected payback period and carbon savings highlight its potential for widespread adoption, particularly in areas seeking sustainable solutions to rising indoor temperatures and energy demands.

Advances in Solar-Driven Cooling Technologies
Traditional home cooling methods rely heavily on electricity from fossil fuels, contributing to greenhouse gas emissions. Recent research has explored integrating renewable energy sources with thermal storage to improve efficiency. The use of phase change materials (PCMs) like waste cooking oil is gaining attention for their sustainability and low cost. Prior efforts have focused on PV-based cooling, but combining it with thermoelectric modules and bio-based PCMs represents a novel approach. The study from India builds on these developments, demonstrating a simulated model with promising performance metrics.
“The novelty lies in converting a waste resource into a low-cost thermal energy storage material for sustainable cooling applications.”
