What is the Difference Between Cooler and Air-Conditioner?

The main difference between a cooler and an air-conditioner lies in their cooling mechanisms and their impact on the environment. Here are the key differences between the two:

1. Cooling Mechanism: Air coolers work by drawing fresh air from the outside, introducing moisture into the atmosphere, and then cooling it down through evaporation. This process makes the perceived temperature more comfortable. Air conditioners, on the other hand, use a refrigerant gas to cool the air and remove moisture, resulting in cooler but drier air.
2. Humidity: Air coolers do not dry out the air in the room, making the air circulated from an air cooler more preferable for people with asthma or dust allergies. Air conditioners often remove moisture from the surrounding air, which can aggravate asthma and allergy symptoms and cause dry skin and eyes.
3. Installation and Portability: Air conditioners usually require professional installation and cannot be easily moved from one place to another. Air coolers, however, do not require professional assistance for installation and are portable, making it easy to move them from one room to another.
4. Energy Efficiency and Cost: Air coolers consume up to 75% less electric energy than air conditioners, making them more economical. Air conditioners are known to increase electricity bills, whereas air coolers have a lower operating cost.
5. Effectiveness: Air coolers work best in hot, dry regions and when placed near an open door or window. Air conditioners can lower the temperature far more than is possible with an air cooler and are effective in various climates.

In summary, air coolers are more economical and suitable for hot, dry regions, while air conditioners provide a more comfortable and cooler environment. When choosing between the two, consider factors such as energy efficiency, portability, and the desired temperature change.
