  Innovative waste‐heat recovery using transcritical CO₂ vapor compression and thermoelectric generators boosts cooling efficiency 🌡⚙️. Sustainable energy conversion transforms lost heat into useful power ⚡🌍. Smart design, low global warming impact, and future‐ready green technology for eco-friendly refrigeration systems 🚀♻️ In modern refrigeration and air-conditioning technologies, Carbon Dioxide (CO₂) stands out as a natural, eco-friendly refrigerant . The Transcritical CO₂ Vapor Compression Cycle operates above CO₂’s critical point , allowing high pressure and temperature levels. However, this also produces considerable waste heat 🌡️. Instead of releasing this heat to the atmosphere, Thermoelectric Generators (TEGs) can cleverly convert waste heat into usable electrical energy , improving system efficiency and sustainability.⚡🌍 🔹 Concept of Transcritical CO₂ Cycle 📌 Key Features Operates in two regions : subcritical (evaporation) & transcritical (gas cooler...
