MLC Knowledge Integration Forum: The Air conditioner without electricity  – A Captivating Sharing by Prof. Song Haomin

On October 16, 2024, MLC held a Knowledge Integration Forum at the Aesthetic Education Hall. This event featured a lecture by Prof. Song Haomin, Assistant Professor at the Institute of Applied Physics and Materials Engineering of University of Macau and college fellow of MLC, who shared insights on the topic of  “The Air conditioner without electricity  .”

How can we enjoy coolness without using electricity? This seems like a challenging problem, but Prof. Song unveiled the mysteries of radiative cooling. He introduced the principles and applications of this cutting-edge technology, from spectra to polymer films, in an accessible manner. This technology not only allows solar panels to cool down in extreme heat, enhancing their efficiency but also holds promise for protecting glaciers and alleviating global warming.

During the lecture, Prof. Song used vivid language and rich visual materials to guide us into the world of radiative cooling. He emphasized that the core of this technology lies in using specially designed materials to emit heat back into space through radiation, thus achieving a cooling effect without consuming any electricity. This undoubtedly provides new ideas for tackling global warming and conserving energy.

Additionally, Prof. Song engaged in enthusiastic interactions with students, answering various questions posed by the audience. His patient and detailed responses deepened the attendees’ understanding of radiative cooling technology and sparked their strong interest in the subject. In conclusion, Prof. Song summarized the potential and prospects of radiative cooling technology, highlighting its significant role in promoting energy conservation, emissions reduction, and achieving carbon peak and carbon neutrality goals.

MLC 知識整合論壇：探索不用電的空調——宋昊旻教授精彩分享

2024年10月16日下午，澳大知識整合論壇在馬萬祺羅柏心書院美育學堂舉行，本次講座有幸邀請到澳門大學應用物理與材料工程學院助理教授宋昊旻博士，為院生帶來題為“不用電的空調”的精彩講座。

炎炎夏日，如何能在不使用電力的情況下享受清涼？這似乎是一個難以解決的問題，宋教授為我們揭開了熱輻射制冷的神秘面紗。他從光譜到聚合物薄膜，深入淺出地介紹了熱輻射制冷這項前沿技術的原理與應用。這項技術不僅能讓太陽能電池板在酷熱中降溫，提高能效，還有望為保護冰川、緩解全球變暖提供新的解決方案。

講座中，宋教授以生動的語言和豐富的圖片資料，帶領我們走進了熱輻射制冷的世界。他強調，這項技術的核心在於利用特殊設計的材料將熱用輻射的方式發射回太空，從而實現制冷效果，無需消耗任何電力。這無疑為我們應對全球變暖、節約能源提供了新的思路。

此外，宋教授還與現場師生進行了熱烈的互動，回答了大家提出的各種問題。他耐心細緻的解答，讓現場師生對熱輻射制冷技術有了更深入的了解，也激發了大家對這項技術的濃厚興趣。最後，宋教授總結了熱輻射制冷技術的潛力與前景，強調這項技術在推動節能減排，實現碳達峰、碳中和等方面的重要作用。
