Did Persians invent refrigerator?
In 400 BCE, the ancient Persians created the world’s first ever refrigerator. The Persian word for fridge – Yakhchal – translates as ice pit, which is very much how the modern day fridge started out.
How did a Yakhchal work?
A yakhchāl takes advantage of the low humidity in desert climates which promotes the evaporation of water (making evaporative cooling more effective) and promotes rapid cooling once the sun sets (water vapor inhibits radiative cooling in less arid climates).
How did the Persians make their cold treat?
Some of them, like Persians, built yakhchals. Yakhchal is a type of evaporative cooler which cooled the air through the evaporation of water.
How deep is a Yakhchal?
These types of Yakhchals are reported to have been constructed from locally sourced adobe containing mud and binding materials such as animal hair and egg white. The height of the dome at Meybod is around 15m tall and pit about 5m deep.
Who invented REfrigerator?
1913. The first electric refrigerator for domestic use was invented by American Fred W. Wolf and was called the Domelre, or the DOMestic ELectric REfrigerator. His model was a flop, but one of his innovations – the ice cube tray – caught on and was included in competitors’ models.
How did they get ice in the Middle East?
The creation of yakhchāls (a Persian word – yakh meaning “ice” and chāl meaning “pit”), a structure which worked as a cooler, allowed the freezing of water to take place. Yakhchāls were large above ground structures built with heat-insulating materials which served as coolers during the hotter months of the year.
How did ancients make ice?
For millennia, those rich enough got servants to gather snow and ice formed during the winter and stored it in straw-lined underground pits called ‘ice houses’. But the ancient Persians stumbled across a neat bit of physics that allowed them to create ice from water even during the summer.
How do Arabs make ice?
Water in the qanat does not evaporate in the sun and stays cooler because it’s underground. Make ice: To make ice the Persians built plaza-like ponds, shaded by a high wall, where the shallow water froze on winter nights. Collecting the ice before sunrise, they stored it in the ice house (dome in the background).
Can a yakhchal make ice?
Once water is stored inside the yakhchāl,it’s able to freeze into ice because of the extremely low temperatures that the structure creates. The hole in the center allows cold air to enter and make its way all the way down to the subterranean bottom, where water is stored.

How do Persians make ice?
Make ice: To make ice the Persians built plaza-like ponds, shaded by a high wall, where the shallow water froze on winter nights. Collecting the ice before sunrise, they stored it in the ice house (dome in the background). Here are two photos of the same ice plaza no longer in use.
Did ancient Egypt have ice?
Using ice to cool drinks dates back to the ancient Egyptians, Athenians, and Mesopotamians who put ice or snow into their wine or water.
What did people before refrigerators?
Natural sources such as streams and caves were a great cooling option. The deeper the cave in the earth, the cooler the air would be. Streams also offered a way to cool things faster due to the flowing water moving around the object.
Did Egypt have ice?
The ancient Egyptians made their own ice. Women placed shallow clay trays of water on straw beds. Evaporation, combined with the drop in night temperatures, froze the water. Cool night air circulated from the air shaft built in the middle of their houses.
