The Role of Soya Oil Ester in Water-Based PCM for Low Temperature Cool Energy Storage

Abstract

This study focuses on the preparation of the water-based phase change material (PCM) with very small soya oil solution for low temperature latent heat thermal energy storage (LHTES). Soya oil ester is soluble very well in water and acts as nucleating agent for a novel solid-liquid PCM candidate that is suitable for low temperature cool storage in the range between −9°C and −6°C. Thermal energy storage properties of the water with very small soya oil ester solution were measured by T-history method. The experimental results show that very small amount of soya oil ester in water can lower the freezing point and trigger ice nucleation for elimination of the supercooling degree. The phase transition temperatures of the water-based PCMs with soya oil as nucleate agent were lower than those of individual water. The thermal properties make it potential PCM for LHTES systems used in low temperature cool energy storage applications.

Nanocellulose-based composite phase change materials for thermal energy storage: status and challenges

“…Other organic substances like pure alkanes, alcohols, and polyethylene glycol (PEG) also serve as PCMs for LHS applications and their thermophysical properties are summarized elsewhere. 117,118 Besides, the use of ester PCMs has been actively reported, 119–121 suggesting the broad availability of organic PCMs for TES applications.…”

Influence of phase change materials on thermal comfort, greenhouse gas emissions, and potential indoor air quality issues across different climatic regions: A critical review

“…14 Recent research developments in the field of green chemistry have proved the feasibility of using plant extracts such as vegetable oil (ie, corn, soya bean, and sunflower) for the synthesis of sustainable PCMs for cooling applications in buildings. [39][40][41] These recent innovations in organic PCMs synthesis are expected to contribute to reducing the toxicity, corrosiveness, and inflammability challenges associated with commercial PCMs while improving their recycling potential. 42…”

“…Minyak sayur mengandung berbagai jenis asan lemak jenuh dan ester dari minyak tersebut memiliki potensi yang baik sebagai bahan PCM organik [15]. Bahan organik dari ester minyak jagung dan berbahan dasar air juga berpotensi menjadi PCM organik untuk temperatur di bawah 0°C [16,17]. Campuran ester tersebut dilaporkan mampu menurunkan titik lebur dan titik beku air, sehingga mampu diterapkan pada aplikasi refrigerasi temperatur medium dan rendah.…”
