    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.

    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.

      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!

    • @0ooTheMAXXoo0

      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.
