The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to –273.15 °C, –459.67 °F or 0 K).^[1]

18th century BCE – 18th century

• c. 1700 BCE – Zimri-Lim, ruler of Mari in Syria commanded the construction of one of the first ice houses near the Euphrates.^[2]
• c. 500 BCE – The yakhchal (meaning "ice pit" in Persian;) is an ancient Persian type of refrigerator. The structure was formed from a mortar resistant to heat transmission, in the shape of a dome. Snow and ice was stored beneath the ground, effectively allowing access to ice even in hot months and allowing for prolonged food preservation. Often a badgir was coupled with the yakhchal in order to slow the heat loss. Modern refrigerators are still called yakhchal in Persian.
• 1396 CE - Ice storage warehouses called "Dong-bing-go-tango (meaning "east ice storage warehouse" in Korean) and Seo-bing-go ("west ice storage warehouse") were built in Han-Yang (currently Seoul, Korea). The buildings housed ice that was collected from the frozen Han River in January (by lunar calendar). The warehouse was well-insulated, providing the royal families with ice into the summer months.{{citation needed|date=October 2012}} These warehouses were closed in 1898 CE but the buildings are still intact in Seoul.
