The Ultimate Guide to Evaporative Air Coolers
Living in Singapore will surely get you wondering what type of air cooling system is ideal for your needs. An air cooler is an environmentally-friendly solution to give your indoor air quality a refreshing boost.
What is an Evaporative Air Cooler?
An evaporative air cooler, also called a swamp cooler or simply an air cooler, is a cooling appliance that uses the natural process of evaporation to blow cool air into a space. An air cooler does not use the complex mechanism and refrigerant that is present in air conditioners. This makes the air cooler a more environmentally-friendly appliance choice.
An evaporative air cooler is ideal for hot and dry weather as it adds moisture to the air, producing a refreshing breeze. This can help prevent dryness of the eyes and skin, sore throats, and other issues caused by dry air.
How Does Evaporative Cooling Work?
The evaporative cooler has three major parts: the fan, pad, and water vessel. It uses the concept of evaporation to provide cool air into the indoor area. Hot air is drawn into a water pad to cool it. When water evaporates, it turns into gas, starting from the highest energy particles, which cools it down. The cool air will then circulate back into the area. The same principle applies to sweating. When you sweat, the liquid will absorb the heat from your skin.
Many evaporative air coolers come with special features like air filters to get rid of dust and allergens while cooling the air.
Advantages of an Evaporative Air Cooler
- Air coolers are energy-efficient. They consume less electricity than air conditioners.
- Air coolers provide cooler air than a regular fan.
- Air coolers do not require installation.
- Air coolers are portable.
- Many air coolers are designed to occupy less space.
- Air coolers are affordable.
- Air coolers work even in open spaces.
- Air coolers add moisture to dry air.
Disadvantages of an Evaporative Air Cooler
- Air coolers are not the best choice for places with high humidity levels.
- Air conditioners require regular water changes or refilling.
- Air conditioners provide less temperature control compared to air conditioners.
- Air coolers have limited filtration systems that will not capture smaller particles.
Types of Evaporative Coolers
Desert Air Coolers
They are large units with large water capacity. These are ideal for bigger rooms and commercial spaces. They can run longer than personal units due to their large capacity.
Personal Air Coolers
These are compact and highly portable units that are perfect for bedrooms and smaller areas. They operate quietly and consume less electricity.
Tower Air Coolers
Tower air coolers are tall and slim, making them the perfect fit for smaller spaces. They are lightweight and stylish.
Air Cooler vs. Air Conditioner
The major difference between an air conditioner and an air cooler is their function. Although both appliances offer cooler and better air quality, they achieve their functions in different ways.
As we mentioned earlier, an air cooler uses the process of evaporation to cool the air. On the other hand, an air conditioner uses a more complex process that involves a refrigerant. The internal fan of an air conditioner absorbs the hot air from the room and runs it into filters to remove dirt, odour, and harmful particles. This filtered air will pass through the evaporator coil. The liquid refrigerant inside the evaporator coil will absorb the heat as it turns into gas. The cooler air will then circulate back into the room.
Unlike an air cooler, the air conditioner must be used in a closed room. It also requires proper installation work. Since it operates harder, in a more complex process, an air conditioner consumes more electricity than an air cooler.
As for the purpose, evaporative air coolers are beneficial for places with hot and dry weather, while an air conditioner works well in hot and humid places.
