Choosing the Best Type of Cooler for Your Home

There are different types of air coolers and each has different functioning and benefits. Direct evaporative, indirect evaporative and dual-stage evaporative coolers work in different ways and are meant to address different types of needs.

When it comes to the hot Indian summer, air coolers are simply the most effective equipment to help fight the sizzling high temperatures. There are so many different types of coolers available in the market and each one offers its own set of advantages. So how will you make the right choice of cooler for your home?

Types of Air Coolers

There are 3 main types of air coolers based on their functions. All these coolers can be categorized into desert coolers or room coolers based on whether they are installed on the windows or placed within the room.

  • Direct Evaporative Coolers: These are the most commonly used coolers which can be found in most homes. Often considered as the best air cooler, this type of cooler works by lowering temperatures using evaporation.
  • Indirect Evaporative Coolers: This type of cooler works by using certain type of heat exchanger. In this case the cooled moist air will be detached from the external environment.
  • 2-Stage Evaporative Coolers:  This type of cooler has a dual-stage cooling function. It will pre-cool the air using a heat exchanger and then the cooled air will pass through special water-soaked padding. This unique mechanism helps in reducing humidity. So if you are living in an area where the summers are extremely humid, this can be the best air cooler for you.

Room Coolers & Desert Coolers

As already mentioned, coolers are also classified into major categories as room coolers and desert air coolers. The desert coolers can be simply referred to as window coolers because they are installed on the window and pull air from outside. You will find the desert cooler to be better in terms of cooling effects. However, when it comes to efficiency, they consume more electricity. At the same time, these coolers require more water and space. If there is a place in your home where the temperatures can go very high, you should install this type of cooler.

On the other hand, a room cooler is recommended for small areas in your home that don’t get too hot. This type of cooler is also referred to as a personal cooler and is simply placed inside the room and pulls the internal air.

Coolers can also be classified into another kind of category – portable air cooler and non-portable coolers. Most of the coolers are classified into the latter type. The portable ones, as the name suggests, can be carried around so that you can create a cool environment wherever you like to spend time.

How Do Evaporative Coolers Work?

Evaporative coolers, also known as swamp coolers, are used mostly in areas where the conditions are dry. These coolers work by pulling fresh outdoor air using moist padding. The air is cooled through evaporation. The cooled air is then circulated in the space. This type of cooler is capable of lowering temperatures by almost 30 degrees compared to the outdoor temperatures.

This type of air coolers are considered to be more efficient in terms of reducing cooling costs. This is because they have simpler technology involving a fan. If you live an area with dry conditions, a direct evaporative cooler is a good option because it will increase your home or room’s humidity. An indirect evaporative cooler however doesn’t increase the room’s humidity.

So if you are looking for the best air cooler, make sure to consider the different options available in the market. It will be worth doing some research by considering the summer conditions in your place, the need for portability and other factors when choosing the right cooler.
