Rental Guide: Evaporative Air Coolers

Developed in line with the concept of evaporation, evaporative coolers are arguably the most efficient piece of cooling equipment available in the market today. Evaporative coolers make use of water-soaked pads to produce a cold and refreshing air to keep you comfortable under scorching summer conditions. Also known as swamp coolers, evaporative coolers work differently when compared to traditional cooling equipment such as ACs and Misting fans. The latter is more so used outdoors; it has a small water outlet that sprays water which is then distributed across the room by a fan. AC’s are ideal for closed indoor spaces and work by converting hot air into cold air.

Understanding the Mechanics of These Coolers

As mentioned earlier, evaporative coolers work based on the principle of evaporation. It requires an adequate supply of water to run successfully. Water collected inside a reservoir at the bottom is drawn onto the cooling pad through a pump. Then the warm air from the environment is sucked in and passed through the damp cooling pad. The warm air heats up the water which eventually evaporates leaving behind cool air with some content of moisture. Cool air is then circulated into the environment through a big fan. In short, it is a cost-effective method (unlike an AC) to provide cool air in any room on a hot sunny summer day.

Air Flow & Water Tank Capacity

The two main characteristics that affect the performance of an air cooler is water tank capacity and airflow. Water supply is required to cool down the warm air. Hence, water tank capacity is a key element that helps to decide how much area can be cooled in a given time. Open-air or bigger rooms require evaporative air coolers with more tank capacity to achieve the desired amount of cooling. Newer generation air coolers come with the feature of directly connecting water storage tank to a running supply of water, so it can be filled whenever needed. Coming to airflow, CFM rating indicates how quickly air passes through the equipment in 60 seconds. Always opt for an evaporative cooler with a higher CFM rating to achieve faster cooling.
