Understanding the Concept: What are Swamp Coolers

Understanding the Concept: What are Swamp Coolers

Often referred to as evaporative coolers, swamp coolers are low-cost and effective cooling systems, especially in dry, hot climates. This type of cooler relies on the natural process of evaporation to cool the air in commercial settings while using less energy than traditional air conditioning systems. The term “swamp cooler” may paint a picture of a dank, misty place, but in reality, these devices can provide refreshing, natural, and purified air by harnessing the power of water evaporating in a dry environment.

Comprehending how these systems function is relatively straightforward. A fan draws in warm, stale air from outside, which then passes over water-soaked pads. As water from the pads evaporates, it absorbs heat from the air, causing the temperature to drop considerably. Moist and cool air is then circulated in the room, driving down the overall temperature. To get a better grasp of the concept, let’s look at some crucial components:

  • Pump: Circulates water from the reservoir onto the cooling pad.
  • Cooling pads: These serve to saturate the air with moisture.
  • Fan: Pulls in warm air from outside and circulates cool air inside.
  • Reservoir: Holds the water needed for cooling.

Swamp coolers have made a significant mark in history due to their minimal ecological footprint, cost-effectiveness, and efficient cooling properties. The table below illustrates the core differences between Swamp coolers and traditional air conditioners.

Digging Deeper: History and Evolution of Swamp Coolers

Swamp coolers, often referred to as evaporative coolers, date back to ancient times. Even in the prehistoric era, the basic principle of cooling was in practice, especially in dry, hot climates. However, the modern swamp cooler has its roots traced back to the 20th century, with the first patent being issued in 1906 to the American Garret Elmore. Since then, it has undergone numerous transformations, making it a powerful tool for the commercial cooling sector. Its evolution has contributed significantly to energy-saving cooling solutions leading to a high demand for them in various commercial spaces including restaurants, warehouses, fitness centres, malls, and even schools.

Year Evolutions
1906 First official patent for swamp cooler
1930s Introduction of the axial-flow fan
1950s Integration of refrigeration and evaporative cooling
1990s Introduction of energy-efficient swamp coolers

The functionality of Swamp Coolers is based on the simple physics of evaporation; with warm air passing over water-soaked pads, causing the water to evaporate and thus cooling the air. The empowered cold air is then circulated throughout the commercial space offering a naturally refreshing and soothing climate. One phenomenal feature of swamp coolers that separate them from conventional air conditioning units is that, instead of just recirculating the same air, swamp coolers continuously supply fresh, cool air thereby improving the overall air quality. Some diverse applications of Swamp Coolers in the commercial sector include:

  • Malls & Shopping Centers: Swamp coolers offer pleasant shopping experiences by providing a cool, refreshing indoor climate.
  • Large Warehouses: Being energy efficient, swamp coolers are perfect for large space cooling without affecting the total operational cost.
  • Restaurants: They help create a comfortable dining ambiance by regulating indoor temperatures.
  • Offices: The fresh, cold air supplied by swamp coolers increase employee productivity by offering an amiable working environment.

Detailing the Functionality: How do Swamp Coolers Work

Detailing the Functionality: How do Swamp Coolers Work

Swamp coolers, also known as evaporative coolers, work based on the simple principle of evaporation. They consist of a simple box frame, including sides and a bottom, a wet mat, and a fan. Initially, hot and dry air is pulled into the cooler. This air is then passed over a wet cooling mat. As the air moves across the mat, it causes the water within the mat to evaporate absorbing heat in the process. This causes the air to become cooler and gain humidity. Finally, the fan propels this cooled air out into the room, thereby lowering the overall room temperature.

The functioning of a swamp cooler is incredibly energy-efficient, as it can effectively cool a space using only 1/4 of the energy of a standard air conditioner. This is largely due to the fact that they only have to power a water pump and a fan. However, swamp coolers work best in hot, dry climates, where the added humidity can be beneficial. In more humid conditions, the swamp cooler is less effective, as the air is already saturated with moisture. It’s also worth mentioning that swamp coolers can be beneficial for indoor air quality. They consistently circulate fresh air throughout the space, unlike traditional A/C systems which simply recirculate the same air.

Spotlight on Selection: Choosing the Right Swamp Cooler for Your Business

Spotlight on Selection: Choosing the Right Swamp Cooler for Your Business

When it comes to cooling your commercial space effectively and economically, a swamp cooler, also known as an evaporative cooler, can be an excellent choice. The very first evaporative cooler was invented thousands of years ago and was made popular in ancient Egypt and Persia. People would hang wet blankets over windows and doorways, and when the hot, dry desert wind blew through the damp cloth, it would bring a refreshing coolness to the room. Modern swamp coolers have come a long way since then but still rely on the same principle of using evaporation to lower air temperatures. Swamp coolers work by passing hot, dry air over water-saturated pads, creating evaporation, which in turn cools and humidifies the air. Choosing the right swamp cooler for your business depends on various factors including the size of your space, the diet of air within and the local climate. Swamp coolers thrive best in hot, dry climates, places where the average humidity is low.


  • Size of the Swamp Cooler: For every square foot of space, you need approximately two cubic feet per minute (CFM) of air. For example, a 2,000 square foot commercial space would require a cooler with a capacity of 4,000 CFM.
  • Ventilation: Swamp coolers operate best in spaces with good ventilation, so make sure your commercial space has adequate air flow.
  • Climate: These coolers are ideal for areas with low humidity. If your area is prone to high-humidity, an air conditioner may be a better option.

A well-chosen swamp cooler can be a cost-effective, eco-friendly way to cool your commercial space. It’s important to note that while swamp coolers may not be as efficient as traditional air conditioners in cooling large spaces, they offer the benefits of a fresher, more natural form of air conditioning that can significantly improve indoor air quality.

Type of Cooler Pros Cons
Swamp Cooler Eco-friendly, cost-effective, improves indoor air quality Not as efficient in humid climates, requires regular maintenance
