I'm from Iran and I've seen the structure of yakhchals used in "Zoorkhaneh"(ancient gym). This kind of structure helped ancient body builders not to sweat. That kind of ancient gyms go back to more than 1000 years ago. They also had one or a few musicians called "Morshed" who perfomed music during exercises and sometimes gave them peptalks and words of wisdom which is amazing. In addition to body building, they also practiced wrestling in zoorkhanehs. Edite: Thank you guys 🙌🏻🙏🏻

Interesting and very impressive. Especially in the desert heat. Stately homes in the UK had icehouses and they also have pointed roofs. They'd put ice in them in the winter and it would last the summer. They also built massive ones by the Thames and they would ship ice from Norway store it in them and then have ice deliveries around London. Restaurants would just get a big block of ice delivered into led-lined rooms and store food in it. This is how people refrigerated things before fridges were invented. If you Google "ice house found under London street" this is one from the 1700s discovered under a London street in 2018.

In Viet Nam, it’s called “giếng trời”. We saw the same structure from caves and found that it really helps reduce moisture, increase air flow for cooling. But we do not make a refrigerator out of this though, we apply to home architecture. It still a challenge. A vacant ground and hollow like vertical space is necessary for this type of home design, but there is not much space to do so. Some construction companies used this idea to attract homeowners, and it turned to be a complete failure (the lands were just too small)

This isn’t a secret, evaporative coolers have been around for centuries. But there’s an interesting detail which isn’t mentioned in this video. Thousands of years ago, they used evaporative coolers exactly like this building to condense water out of the desert air. The coolness of the water in the pool is used to cool the upper bricks by thermal conductivity, so that more water condenses, and then drips down back into the pool, resulting in an endless cycle. It’s a self-powered condensation well.

This was simply a cabinet you put an ice block in a top compartment and the coolness would sink down to the lower cabinet where your food was. My FIL was an ice delivery boy for this purpose. So not that long ago in our history.

The ponds were designed in such a way that they could make make Ice with the air above freezing. At night if there are no clouds objects radiate heat into space. The ponds were filled with cool water at dusk so they would freeze open to the sky despite the air around being a few degrees above freezing. So in a very real way they were making ice. Just not under any conditions. Obviously measures were taken to make sure the water is a cool as possible prior to flooding the pond.

To cool anything, you need to extract heat from that object, and providing that you continue to extract heat from the object at the same rate, or a greater rate than the object is being heated by the ambient heating conditions, then slowly the temperature of the object will fall. This is basic physics. Thus to cool water held in a vessel, whilst the outside ambient temperature is very hot ie 40 degrees Celsius, is a challenge, but not impossible. Bedouin tribes cool water down in large clay vessels, that are being blown across by the warm desert winds. The clay vessels " weep" and the moisture on the outside of the vessel is subject to natural evaporation by convective air currents. The evaporation of the water on the vessel walls, cools the walls of the vessel, which then by conduction through the wall of the vessel, cools the water therein. The process continues and the water within the vessel, again, providing that the vessel does not gain heat from the surroundings at a greater rate than the coolth being extracted, will continue to cool down. Evaporation can lower the temperature of water by 10 degrees Celsius. If the water within the clay vessel, is continually cooled down, it could reach 2 to 3 degree Celsius, however , I am not aware of this cooling mechanism being able to freeze water! To cool the water to 0 degrees Celsius, demands a huge amount of energy extracted from the water, which is not provided by the evaporation cooling process alone. The Bedouin tribes know what they are doing! Chilled water in the middle of a flaming hot desert! My hat off to them!

You can see ice, frost, on plants when the air temperature is above freezing. Heat is lost, radiated to the cold of space. In the desert they would make shallow ponds with walls around so the radiation lost to space was greater than how much the ambient air flow would heat it and so be able to create ice in the desert night when temperatures were in the mid forties.

Before anyone thinks of building one (lol) he failed to mention that they only work because the are connected to an underground water tunnel called a _qanat_ that bring water from distant mountain outwashes to farms and cools the _yakchāl_ using evaporative cooling. Without a _qanat,_ the storage of ice year around in a desert _yakchāl_ is not possible.

@LeafofLifeWorld Жыл бұрын

They can be made with or without a qanat, the trick is the ancient ac system they use to keep it cool, which we will explain further in this sundays new video, stay tuned

@maytee672 Жыл бұрын

Yakhchal is not related to qhanot. They are dfferent structures. The water to make the ice during cold winter nights could have come from a creek, well or ghanot and yakhchal was designed to preserve it for long warm momths ahead.

While I agree with your point about not underestimating the ancients, I think you're actually underestimating us modern folk. Bear in mind that necessity is the mother of invention; most educated people aren't spending their time trying to figure out how to make ice in the desert because we have ways of doing it. I'd be willing to bet that were the electrical grid to go down worldwide, a lot of these sort of ancient innovations would be rediscovered, likely independently and in separate areas, much as they were in the past.

We do. Conductors and insulators. It’s not about electricity it’s about energy. Learn thermodynamics. You bring enough solid mass of cold to overpower the poor conductive properties of air while sitting in a dug out pit avoiding contact with conductive surfaces, materials science is ancient and ever important to date. Air conditioners or refrigerators use every bit of the same “technique” it’s not gone. Just advanced to where we can use energy a lot more freely with devices to directly move what energy we want where.

this is amazing. I like to think of what "modern" things that, say, the ancient Egyptians could have had and the list is surprisingly long. And includes ice, apparently. A stunning example of this is that they could have had the phonograph. The original phonograph is stone-simple and considering ancient people invented electroplating, it's not too far a leap at all to imagine the phonograph being a 1000's of years old technology.

They also had an interesting way of producing ice right in the desert instead of bringing the ice in from the mountains. They would have a deep narrow north south long pit or rather canyon dug out such that the bottom wouldn't get any Sunlight for most of the day and they would have pools of water at the bottom which would freeze overnight due to the heat radiating to the sky even though they were in the middle of the desert. They also had an interesting way of building cold rooms through evaporation from an underground aquaduct passing under their houses. The aquaduct concept was discontinued in the modern era because it tended to spread diseases between the homes. Now outside the middle east, you had ancient Roman villas which would have chimneys painted black so solar heat would create an updraft in the chimneys through the day and they would have clay pipes with drainage holes drilled into them buried underground so the outside air being sucked into the house through the pioes to make up for the updraft would first pass underground at a depth which would cool the air. Further afield the ancient civilization in India would have terracotta vases where they would put dry bushes or straw and then they would put water in the vase so that the wind blowing past the bushes would evaporate the water drawn up by capillary action to cool the air. There's a lot of fascinating ancient technology but it is clear that only the wealthy benefited from much of it and that's the main difference, more of our population benefits from modern technology then of the ancients from ancient technologies.
