Swamp coolers are ideal cooler appliances, for dry climates with high temperatures, such as Afghanistan, Iran, and Arabia. They serve dual work by moving dry air across a moisture-direct evaporative pad, allowing moisture to be put back into the chilling air. When cool, humid air contacts the chilling pad, the device acts as an insulator and a strong blower dissipates it. The thermal gradient in the nearby region can be reduced by up to 45 ° as a result of the experience.

A swamp cooler can decrease the atmospheric temperature by 15-20 degrees F without increasing moisture in locations where saturation is weak and temperatures remain high. Swamp coolers work perfectly in arid parts of the U.S. 

Swamp coolers are frequently used in all the regions given below as compared to traditional coolers

Arizona

Swamp coolers have more energy than traditional coolers. Swamp coolers might not be as efficient during a certain climate since direct evaporative operates by adding an extra humidifier. That's why, during summer, Arizona homeowners are better represented by turning off their swamp coolers and depending on their cooling systems.

Deserts

Swamp coolers are more energy-efficient than those traditional coolers. Swamp coolers are still a great method to augment regular air conditioning at a minimal cost. They perform admirably in our arid heat and consume significantly less energy than that an air conditioning system. They operate better when the heat is far less than 100°F (38°C) and the moisture is less than around 27%.

Afghanistan

The temperature in Afghanistan during the summer months exceeds 100 degrees. It is considered very hot. Swamp coolers are used more frequently in Afghanistan during the summer season than traditional coolers

South California

The high dunes in the region of southern California and offshore colonial areas, which seem to be typically dry, scorching, and contain very little moisture, are all the areas which are benefited from swamp coolers traditional coolers might not be applicable to use than that of swamp coolers.

Los Angeles

Swamp coolers are the best option for hot climate control in a dry atmosphere, such as the Los Angeles, area rather than traditional coolers. Since the air surrounding is already so arid, it may tend to accumulate a large portion of total water, making them more efficient.
