🧊 冷 = cold + 蔵 = storehouse, so a cold storehouse = refrigeration
蔵 means storehouse or to store, as in 貯蔵 (storage). 冷 means cold. Together they name keeping food and goods cold in storage.
冷 — ice radical 冫 + order 令
A semantic-phonetic compound. The left side 冫 (ice) supplies the meaning of coldness, while 令 (lìng, 'command/order') hints at the pronunciation. Originally referring to the chill of ice, 冷 broadened to mean cold in general, and figuratively cool, indifferent, or detached.
