Finding economical and energy-efficient cooling solutions becomes essential as Bangladesh’s industrial facilities experience rising summer temperatures. In hot and dry conditions, evaporative air coolers are a great substitute for traditional air conditioning systems.

Proper placement, maintenance, and a comprehensive understanding of climate impact are essential to ensuring optimal performance from your industrial evaporative air cooler.

To optimize the efficiency of these coolers, we will go through the process of how to install the evaporative coolers correctly in industrial facilities throughout Bangladesh, paying particular attention to elements like climate suitability, water availability, and location.

Key Considerations for Installing Evaporative Air Coolers: Climate, Location, and Efficiency

For evaporative coolers to function, warm air must first be drawn in, then it must pass through pads soaked in water before being released back into the room.

Before installation, there are a few crucial things to think about. The climate and location significantly impact how well evaporative air coolers work. Although they work best in arid climates, they might not work as well in humid settings like coastal regions or during the monsoon season.

Since the units need a constant water supply to operate at their best and draw air from the outside, installation must be carefully planned. Effectively cooling large industrial spaces requires proper installation in key locations, such as windows, roofs, or ground levels.

Climate Appropriateness

Hot, dry climates are ideal for evaporative air coolers. However, in humid conditions, like coastal areas or during the monsoon season, their effectiveness drastically declines.

As a result, these coolers might not work as intended if you’re working in an area that frequently experiences high humidity.

Location of Installation

These coolers need to be placed outside because they are dependent on drawing air from the outside. They can be positioned in attics, on rooftops, or at ground level to cool larger spaces, or they can be mounted on windows to cool particular areas.

Considering that, it’s important to place the cooler close to a dependable water source because it needs a steady supply of water to operate properly.

Evaporative Cooler Types

The main purpose of evaporative cooling systems is to relieve heat in hot, dry climates effectively. Warm air is cooled by passing it through pads saturated with water, which lowers the air’s temperature before it is released into the building.

Step-by-Step Guide to Installing Evaporative Air Coolers

Step 01 (Choose the Installation Method Evaporative Coolers)

The installation can be done in two main ways:

Centralized Installation:

In this technique, the cooler is positioned so that air is blown straight into the center. It works best in buildings with an open floor plan where air can flow freely between rooms or in smaller industrial spaces.

Ducted Installation:

Attaching the cooler to ductwork is crucial for larger industrial facilities with distinct sections or corridors. Cooled air is effectively distributed throughout several areas by the ducted system.

Step 02 (Select the Appropriate Placement)

Roof-Mounted Downflow Units:

Downflow units that are mounted on the roof are frequently used to draw air into buildings from below. Despite their effectiveness, they can be difficult to maintain and increase the chance of roof leaks.

Ground-Mounted Horizontal Units:

Due to their ease of maintenance and lower chance of structural problems, many professionals favor ground-level horizontal units. By blowing cool air straight into the building, these units are mounted on the side of the structure.

Step 03 (If Applicable, Install Window-Mounted or Portable Units)

Horizontal-flow coolers can be installed in windows to cool designated areas in smaller sections or individual rooms of an industrial building. Although extreme heat may lessen the effectiveness of these units, they are appropriate for moderate climates.

Room temperatures can be lowered by 5° to 15°F with window-mounted or portable evaporative coolers in regions with milder summers, like parts of the western United States, however, it may differ from Bangladeshi temperatures.

Step 04 (Consider Portable Units)

There are mobile evaporative coolers for industrial settings that need adaptable cooling solutions. Although these units are portable, the building’s humidity level affects how well they cool. They work best in dry conditions, and in more humid ones, they might only slightly lower the temperature.

Evaporative Cooler Maintenance for Industrial Facilities

Your evaporative air cooler needs to be maintained regularly to guarantee long-term performance and avoid expensive repairs. The cooler should be regularly drained and cleaned to prevent problems brought on by sediment and mineral accumulation. Every cooling season should begin with a thorough cleaning, and any necessary maintenance should be performed throughout the season, particularly during times of high usage.

The cooler will need more maintenance the more often it runs. Important parts like the pads, filters, reservoir, and pump should be inspected at least once a month in hotter climates where the cooler is used for longer periods. Generally speaking, cooling pads should be changed at least twice during the season, or more frequently if the unit is used continuously.

Depending on the manufacturer’s instructions, some cooler pads composed of paper or synthetic materials can be cleaned with soap and water or a mild acidic solution. Every time the pads are changed or serviced, filters should also be cleaned. To ensure safety, always remember to turn off the power source before beginning any maintenance.

Industrial evaporative coolers will operate more effectively if these maintenance procedures are followed, which will improve cooling outcomes and extend equipment life.

Conclusion

In Bangladesh, evaporative air cooling provides a cost-effective and energy-efficient way to cool industrial buildings, particularly during hot and dry weather.

Evaporative cooling is a good option in many areas of Bangladesh, even though it performs best in arid climates, provided that the humidity levels are appropriately considered. The installation process must be tailored to the particular needs of the facility, whether it is centralized, ducted, or portable.

Regular maintenance, like cleaning and pad replacement, will also ensure the cooler’s long-term performance and efficiency.

Frequently Asked Questions (FAQs)

What materials are in evaporative cooling?

Evaporative cooler pads have traditionally been made from excelsior (aspen wood fiber) enclosed in a containment net. However, newer materials like certain plastics and melamine paper are now being used as alternatives for cooler pad media.

What is the temperature limit for evaporative cooling?

Evaporative coolers have the potential to lower air temperatures by up to 30°F under ideal circumstances. Nevertheless, the cooling effect varies according to the outdoor air temperature and humidity. A cooler, for example, can drop the temperature from 125°F with 2% humidity to 83°F, but it might only drop the temperature from 75°F to 72°F at 80% humidity.

Do evaporative coolers need ventilation?

Enough ventilation is necessary because evaporative air coolers raise the air’s moisture content. A comfortable atmosphere is ensured by letting air circulate freely, which also increases the cooler’s efficiency and keeps indoor humidity levels from rising too high.
