The Ancient World’s Ingenious Ice Making Air Conditioning System
Today I Found Out・2 minutes read
Wind catchers have been integral to ancient air conditioning systems in regions like Yazd, Iran, utilizing natural cooling methods without electricity and have been used for nearly 1,500 years in Iran. They work by directing cool air into buildings, expelling hot air, and drawing in cooler air through various effects for enhanced cooling, alongside night flushing and evaporative cooling techniques.
Insights
- Wind catchers, like the badgirs in Yazd, Iran, have been utilized for centuries as an effective and sustainable method of cooling buildings without electricity, showcasing a historical and innovative approach to environmental comfort.
- The integration of wind catchers with other cooling techniques such as night flushing and evaporative cooling highlights a sophisticated understanding of passive cooling systems in ancient Persia, emphasizing the importance of combining different methods for optimal efficiency in maintaining low temperatures.
