Inexpensive Home Building

Cut through the jargon and nonsense of home building and house construction by starting from zero dollars and trying to figure best-value bang-for-your-buck when choosing construction methods or construction materials. My research might answer some of your questions and at other times perhaps you have the knowledge or experience to post the answers to my questions and thereby help others too. The goal is an affordable and sustainable home for all.

Ancient Egyptian Air Conditioner: Cheops Ships in 2600 BC Egypt

Part of: "What Is a Fly Roof? How To Build a Flying Roof."

Ancient Egyptian Air Conditioner over 4,000 Years Old

Ancient Egyptians of 2600 BC during the Old Kingdom buried 2 ships near the Great Pyramid of Pharaoh Cheops (Khufu) and the ships are known as “Cheops boats,” Cheops ships,” “Khufu ships,” or “solar ships.” The papyriform “Cheops 1” (the only one excavated) shows a cabin that used a fly roof as an air-conditioner by stretching a canvas tarp over the wooden frame and soaking the tarp with water for evaporative cooling--causing the building to sweat so the pharaoh didn't have to:

Ancient Egyptian air conditioning systems were along the line of what we might call “swamp coolers” today; they were evaporative units ( malqaf ).

During most of the year, the wind in Egypt is from the north. That provided two ongoing bonuses. The Egyptians could “float” downstream ( south to north ) and with the wind from the north, could use sails to get back up the river again ( north to south ). It also meant that ‘wind catchers’ could be placed on top of various buildings, such as homes, and as long as the north wind blew, it provided a steady stream of air into the interior. The Egyptians then placed pads of water soaked linen in the path of the moving air and the evaporation cooled the air before it entered the house. Some of these units had roof tanks which were filled with water and a slow drip kept the pads moist – - thus the need for our plumber.

This ancient air conditioning technique can be compared to the modern day "flying roofs" and "evaporative coolers". Like Rain said, the Egyptians took advantage of the abundant north wind. They added sails to their boats, made ancient wind vanes and air conditioning techniques by directing the wind downwards, combined with the soaked tarp.

Today, these techniques are now applied by most roofing contractors. Vancouver has a lot of establishments that uses a fly roof - a roof not attached to the structure's wall - letting air pass through. This style was derived from the ancient Egyptian's ingenious manipulation of the incoming north wind. Our roofing contractors (BC/British Columbia), intentionally or not, has definitely been influenced by these ancient roofing techniques.

When your air conditioner motor begins to overheat, it is known to reset itself and turn off. Then once it cools off, it turns back on, but only for a little while before doing the same thing again. Aged air conditioning compressor motors can be replaced to get rid of this problem. Our Skokie Heating & Air Conditioning  will short out this problem.

An air-conditioned shop is likely to provide respite from the world outside, and therefore an opportunity to make more purchases. This isn’t just so in summertime; while we might think of air-conditioners as cooling devices, they’re also able to act as heaters, meaning we can achieve an optimal temperature whatever time of the year it might be.

It isn't recommended to clean your house air ducts each year. Most home air duct systems just need to be cleaned once every several years.

There is a good deal to be said for a paper fan once you learn to move it languidly, especially if you have no other options. I still prefer to be a bit warm for a few days in the summer rather than freeze my toes off in the sterile hum of air-conditioning all season.
