Air Conditioning isn't free... but we're close.
推荐理由
there are a couple good videos about it
说明
这是2023年由Tech Ingredients发布的一部教程,主题归在Power grid, heating & buildings。它讲的是radiative cooling这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Tech Ingredients shows how to build a liquid panel with a specialty paint that, placed outside, cools below ambient air temperature. It demonstrates radiative sky cooling.这些读者给出的理由,核心是:HN points to it in threads on radiative cooling as a hands-on explanation of passive daytime cooling.讲法不绑某一条新闻,过几年仍然可以当材料看。从2023年到2025年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合打开电脑跟着做的人。如果只听不练,这集的价值会少一半。如果已经会了基本定义,就把注意力放在它怎么把radiative cooling变成能跟着复述的例子。
