Summary
Heatwaves are getting longer and more intense around the world, increasing the demand for air conditioning. Air conditioners work by moving heat from inside a building to the outside, using a chemical fluid called refrigerant. The history of air conditioning dates back to 1820 with important developments over the years, making cooling more accessible and efficient.
Key Facts
- Heatwaves are increasing in length and intensity globally.
- Demand for air conditioning is rising because of these heatwaves.
- Air conditioners use a chemical fluid called refrigerant to cool indoor spaces.
- The process involves moving warm air over cold coils, where the refrigerant absorbs the heat.
- British scientist Michael Faraday made a breakthrough in cooling technology in 1820.
- Modern air conditioning started in 1902 with Willis Carrier's invention.
- The first window-mounted air conditioning unit was made in 1931, making cooling more accessible.
- By the 1940s and 1950s, air conditioning saw rapid growth in use due to economic expansion.
