There are some strange ways to cool off the heat. Why did Cao build an ice hanging room to cool down and relax?

The suspended igloo built by Cao Cao should have the same principle as the igloo used by ancient people to cool off the heat. Suspended ice house refers to the huge platform built above the building, and the ice cubes in winter are transported to the storage room by craftsmen. Because it is composed of a huge stone cellar, the heat insulation effect is better, so the ice cubes will not melt when stored inside.

The reason why it is called hanging ice room is because this building is not built on the ground, but in the sky, and a building is built on a huge ice room. There is a well in the middle of the building, which communicates with the ice room on the ground floor. In summer, the ice in the freezer can be carried out and put into the well.

Because of the hot weather, the ice in the well will melt with the temperature, and the chill will spread from the wellhead to the room, making the whole room cool, so you will feel cool and relaxed, and the ice water melted at the bottom will flow out from the special channel at the bottom of the well, which can be used as drinking water or cold drink in summer.

Moreover, this ice room has another function, that is, some fruits and vegetables in summer can be put in the ice room to cool down and become a kind of ice fruit. You can also cut ice cubes into ice shreds and add milk, glutinous rice flour, sugar and other foods as sweets for concubines to cool down and relieve the heat. Although the ancients also had their own tricks to cool down and relieve the heat, they also had their own air-conditioned refrigerators in ancient times.
