I don't know if you have such a feeling, in some ancient buildings or old houses, stepping into it is like another quiet and cool world, which is refreshing and bright.
Why are these ancient buildings so cool in the summer when the heat is so high? What ingenuity did the ancients have in architectural design? Let's take a look at it in this issue.
Cave room
In the pre-Qin period, the "cave room" was a basement that the ancients had built for the purpose of storing wine and cooling entertainment. The high-class caverns are hidden with ice cubes, equivalent to modern "air-conditioned rooms" with refrigeration equipment.
Ice cellars are generally divided into palace cellars according to the location of the place, and there are also folk cellars. There are 25,000 ice cellars in the Forbidden City alone, so you can imagine the number of ice cellars.
Cool house
In the Tang Dynasty, Chang'an and other places appeared for people to cool off the "cool house", generally built by the water, using the way of water circulation to promote the fan wheel to shake (like a folk water wheel), the cool air in the water slowly sent into the house.
Or use machinery to send water to the roof, and then go down the eaves to make an "artificial water curtain" to let cool air into the house. This kind of "cool house" built by using the "water cycle" is both green and environmentally friendly, but this high-end cooling facility is not related to the people.
During the Tang Xuanzong period, the Hanliang Hall of the Daming Palace also adopted a large-scale summer architectural system. Many water wheels were set up inside and outside the building, and the flowing water stirred up the fan blades to turn, and the cold water vapor and cold wind were sent into the temple. This refrigeration plant utilizes natural water cooling and has a high cooling capacity.
From the rain pavilion, that is, the pavilion where water flows from the eaves, the mountain spring flows down from the eaves of the pavilion, forming a screen made of water around it. This kind of water pavilion uses machinery to transport cold water to the water tank on the top of the pavilion for storage, and then let the water flow down from the eaves to form a rain curtain, thus playing a role in summer cooling.
Roof design
The tiles of the roof of ancient buildings are stacked one by one and have many gaps, and in the summer, the heat in the house will be channeled through the gaps, and natural winds can also drill into the house through the gaps in the tiles.
In the choice of building materials are also quite exquisite, these materials have good heat insulation, thermal insulation performance, can absorb a large amount of heat from outside the house, to avoid too much heat directly into the room.
In addition, some important halls will also use heavy eaves roofs, covering an area far larger than the building area itself. This kind of roof achieves the purpose of shading and cooling to a certain extent.
Soil Air Conditioning
By drilling a hole to connect your house to the river below, the cold air from the underground river will be introduced into the room, thus reducing the room temperature.
Because the underground dark river flows all year round and has a constant temperature, the wind that comes out in the winter is a warm wind, and in the summer, the cool breeze is cool, just like a natural air conditioner.
Through the hall wind
The wind through the hall is mainly solved by the cooperation of patios, corridors and lanes, introducing cold air from the patio, forming air convection through indoor corridors and lanes between houses, and finally solving the ventilation problem.
This is reflected in both the ancient city of Pingyao in the north and the Huipai houses in the south.
In addition, some large households, by planting plants in the courtyard, and even creating a stream flow system, have created an artistic mood while solving the problem of ventilation and cooling. The fruit drink is also put into the well with a rope, which can also have the effect of freezing.
The ingenious design of ancient buildings has brought a good life to the ancient people and shocked the world. You also know the cooling wisdom of which ancient buildings, you can leave a message below.
