Things To know About Evaporative Cooler And Its Filter Pads

Living in Australia can be challenging considering the extreme levels of weather. We use different products in our day-to-day life that can help us withstand the extremities of weather by keeping the indoors of our home at a stable desired temperature. Whether it is summer or winter, we have a product available to keep us comfy in our homes. One such product is an Evaporative Cooler.

What is an Evaporative Cooler?

An Evaporative Cooler is a device that cools down your home through the process of water evaporation while other air conditioning systems use vapor compression or absorption refrigeration cycles. It not only keeps the temperature down, but it also adds moisture to the stale, dry air.

Based on the principles of evaporation, the hot and dry air from the outside is drawn through the water-soaked cooling pads. While the air is being pushed through these water-soaked pads, the water evaporates and the heat present in the air is absorbed. As a result, the temperature of the air decreases. This cold air is then pushed throughout the house by a fan via a network of ducts.

Advantages of Evaporative Cooler

An Evaporative Cooler has the following advantages:

  • Simple maintenance
  • Easy to operate
  • Superior performance
  • Greater energy efficiency
  • Healthier flow of air
  • Low water usage
  • Noiseless performance
  • Improved air quality with high ventilation
  • Environmentally friendly
  • Freshens stale, dry air
  • Low operating costs
  • Ideal for dry areas

Disadvantages of Evaporative Cooler

An Evaporative Cooler has some disadvantages that are as follows:

  • Not the right choice for humid areas
  • Excessive use of an evaporative cooler promotes growth of mould due to moisture buildup
  • Poorly maintained evaporative coolers can become a breeding ground of mosquitoes or some harmful microorganisms

What are Filter Pads?

Filters Pads are an essential part of an evaporative cooler that clean out the air being circulated for maximum efficiency and add water to the air thus cooling it down. The Filter Pads must be in a good condition to ensure the optimum performance of the evaporative cooler.

Types of Filter Pads

There are two types of filter pads available in Australia:

  • Woodwool
  • Celdek

Woodwool

This type of Filter Pads is made of shredded wood silvers that are wrapped into pads and have a thickness ranging from 3cm to 5 cm. Woodwool filter pads are more frequently used in old models of evaporative coolers.

Celdek

The Celdek filter pads are made with thin crinkled cellulose sheets that are bonded together in a honeycomb structure. These filter pads become wet faster and are completely biodegradable and recyclable.

The Woodwool filter pads are now being replaced by the Celdek Filter pads due to the greater saturation efficiency and a much greater life span.

Common Problems with the Filter Pads

In areas that have a great amount of calcium present in the water, calcification can occur in the filter pads. That means, small stones of calcium are formed in the filter pads that end up blocking the holes in the pads, eventually making it hard for the fan to draw in the air. Due to this, the evaporative cooler starts consuming a lot more electricity. Since the evaporation process is also limited, you end up losing your evaporative cooler’s efficiency as well.

In areas with heavy winds, the face of the filter pads gets smashed by the winds and heavy rain in such a way that it folds over the holes and causes the restriction the same way calcification does. The evaporative cooler struggles to pull air through the pads and causes the electricity costs to go up.

The filter pads are also prone to wear and tear. They usually last for 2 to 3 years and need to be replaced as they must be packed nice and tight for the air to be cooled the right way.  If the air is to pass through the worn-out filter pads, it won’t be cooled down as the air will have very little or no contact with the water to cool it down.
