The first passenger train rolled in England in 1825, after many improvements to the engine and tracks by engineer George Stephenson.
But few people know that, more than 2,000 years ago During the Qin Dynasty during the reign of Qin Shi Huang, Chinese engineers designed a type of “air-conditioned sleeper car” that ran on specialized rails.
The evidence is proven through a wooden carriage bronze excavated in the western area of Qin Shi Huang’s tomb in Shaanxi China.
When excavating, archaeological experts said that the two bronze chariots were half the size of a chariot. Real. The first carriage is used to pave the way and the second carriage is for the Emperor to use. The car has a bed with double-layer ventilation windows and air conditioning.
It is called “a car with a bed” because the inside of the car uses a soft cushion lining embroidered with delicate patterns. When the vehicle moves, people inside can lie down and sit in comfortable positions at will.
So how is the air conditioning system of the carriage designed?
The carriage part has double-layer windows with Can slide sideways or open. More than 2,000 years later, at the time of excavation, the car window could still be opened and pulled in smoothly.
The outer layer of the window has many small holes while the inner layer can open and close. This special design has created an air conditioning ventilation system that warms the car when it’s cold and cools it when it’s hot.
The carriage has The bed is air-conditioned, but what surprised experts the most was the specialized rail design. To make the carriages run faster and quieter
Emperor Qin Shi Huang also built a separate railway for carriages to serve the court. This track is also called “tri path.
The mausoleum is located north of Ly Son mountain in Shaanxi province, about 50km east of Xi’an. The project was built with a grand architectural scale that is ranked by UNESCO as a wonder world in 1987.
Half a century has passed since its discovery, but this place is still unknown to posterity. because most of the tomb has not been fully explored.
Currently, a part of the terracotta army of Qin Shi Huang’s tomb still welcomes visitors. In 2015, more than 5 million people came here to admire and learn about ancient history.
Qin Shi Huang (259 BC – 210 BC) was the 36th king of Qin.
After destroying 6 vassal states, it ended During the Warring States period in 221 BC, he became the first Emperor to unify China.
