安娜‧羅斯喬爾德: 打破物理定律的技術？

打破物理定律的技術？

通常，對任何技術而言，將一單位的能量輸入，就會得到大約一單位的能量輸出。那是熱力學的第一定律：能量一定會守衡。但是有一種技術，叫做熱泵，它能輸出的熱能是輸入能量的三到五倍。這是什麼巫術？安娜‧羅斯喬爾德要透過這支影片來探討熱泵的科學。

Heat pumps seem to defy physics by producing three to five times more heat than the energy they use. Unlike traditional heaters that burn fossil fuels, heat pumps run on electricity and use clever thermodynamic tricks to move heat from one place to another. In 2021, heating buildings contributed about 10% of global energy-related CO2 emissions, making efficient solutions urgent. While heat pumps are not perfect, their high efficiency and potential climate impact are driving global adoption and innovation.
