18th-century treasure an ingenious cooling method in ancient China

Do you wonder how Chinese people in ancient times stayed cool without air conditioners? During the Qianlong reign (1736-95) of the Qing Dynasty (1644-1911), this exquisite cloisonné enamel chest with floral motifs not only dazzled with its beauty but also served a dual purpose as a refrigerator and air conditioner.

The chest is lined with a layer of tin insulation, preventing heat transfer from outside when ice is placed inside. The cold air is only allowed to escape through two round openwork vents in the shou (longevity) character designs on the lid. There's also a wooden compartment inside for storing and chilling fruits and other food.

Wouldn't you love to have this ancient cooling marvel? You can see it up close at the Shenyang Palace Museum.
