Refrigerator installation and delivery (heat-dissipation clearance varies by model)
Fitting a refrigerator: clearances differ by model, and a corner turns on the diagonal

Notes in the source (in Japanese)
「何センチ空ける」の一般解は無い。
同じメーカーでも、3 ドア以上は上 50mm・左右 5mm・背面 不要、2 ドアは上 300mm・左右 20mm・背面 70mm、1 ドアは上 100mm・左右 20mm・背面 100mm。だから ① は 3 台を並べた —— 違いそのものが中身。
もう 1 つは ③。角で本体を回そうとすると、対角で決まる。幅 785mm の廊下どうしの角で回すと、対角 979mm が壁に当たる。幅も奥行も 785 未満なら、回さずに横へずらせば通る(上から見て、立てたまま平行移動するだけ)。回した本体を破線で重ねてあるのは、回すと壁に当たることを見せるため(交差は中身)。台車で傾けると、上から見た長さが奥行より伸びる —— 角と踊り場ではそちらを測る。
2026-09-29 直し:以前は「角は対角で決まる。979 は入らない」と書いていたが、685 × 699 の本体は 785 の角を回さずに通れる。対角が効くのは回すときだけ。
CROSSINGS_ARE_CONTENT: 角で回した本体が壁に当たることを示す図。交差が結論。

A fridge does not make cold, it pumps heat out — and it throws away more than it took, because the compressor's electricity comes out as heat too
Heating and cooling swap the roles of the indoor and outdoor coils, and the only part that changes is one valve — which is also why a heat pump briefly runs cooling in the middle of heating, to melt its own frost
Hot and cold spots sit 6.1cm apart because that is half of the 12.2cm wavelength, which no cabinet design can remove — so the food is moved instead
A shelf sags with the cube of its span, so doubling the span sags it eight times — and gluing a 40mm rail under the front edge does more than upgrading the board
The same drum has to stay under 1G to wash and reach 335G to spin, which is why it hangs on springs behind a concrete weight rather than being bolted to the machine
Induction heats only the outer 0.05mm of the pan, and that thin skin is why iron works and aluminium does not: at 20kHz iron's surface resistance is 43 times aluminium's
