Cooling Explained: How Do Air Coolers Work?

Well, it’s great to sit in a room with an air cooler cooling the room when it’s scorching heat outside. I’m sure that you also have experienced the same quite a lot of times. But do you know how an air cooler makes it possible to cool the room? 

Air coolers are one of the most common cooling appliances that are present in almost every space. However, only a few know about the science behind the working of a cooler. In this blog, we will be discussing how air coolers work. So, let’s get into understanding the working of the cooler in depth,

Air Cooler and Its Advantages 

Air coolers can be one of the best alternatives when it comes to cooling spaces with moderately high humidity. If you want to switch to cooling alternatives that are more effective than a fan but do not have a budget for an air conditioner, then an air cooler can match your needs. 

Let’s have a look into one of the most effective and efficient cooling options, air coolers:

Energy Efficient

While air coolers might consume more electricity than fans, they consume less electricity than air conditioners. This makes it an energy energy-efficient cooling alternative that can offer effective cooling in spaces with moderately high temperature and humidity. 

Affordable and Ease of Maintenance 

Air coolers are one of the effective and budget-friendly cooling appliances. In places with higher temperatures and humidity, they offer more effective cooling than fans. This makes it a suitable alternative to air conditioners which are one of the costly cooling alternatives. In addition, they are also easy to maintain.

Portable

In comparison to air conditioners which usually need to be fixed at a certain place, air coolers are highly portable. An air cooler does not require permanent installation, they have in-built handles through which they can be easily moved from one place to another.

Environment Friendly 

An air cooler uses a natural evaporation process for cooling the air. They consume less energy, thus producing fewer greenhouse gas emissions compared to air conditioners. In addition, an air cooler does not use any refrigerants which can be harmful to the environment if leaked.

Science Behind Cool Air: How do Air Coolers Work? 

After discussing the advantages of air coolers, let’s now move forward. Moving ahead now we will be discussing how do air coolers work. 

Air coolers work on the principle of evaporative cooling. Evaporative cooling is a natural process in which the process of evaporation takes place by absorbing the heat from its surroundings which results in cooling. Before directly jumping into the working process, let’s first look at the components of air coolers,

Water Tank: A water tank in an air cooler is responsible for holding water that is used in the cooling process. It is where the water is stored for the process of evaporation. 

Water Pump: The water pump is a component of the air cooler that pumps water from the water tank to the cooling pads. 

Cooling Pads: Cooling pads are absorbent pads that are usually made up of cellulose or synthetic fibers. Cooling pads are responsible for cooling hot air through the process of evaporation.

Fan: A fan works for both drawing hot air from the surroundings into the cooler and then later blowing out the cool air into the space.

Now, here’s how the cooling process occurs in the air coolers, 

Water Evaporation: The cooling process starts with evaporating water. The water pump in the air cooler pumps water from the water tank to the cooling pads. The cooling pads are kept wet when the air cooler runs. 

Circulation of Air: A fan present in the air cooler draws warm air from the surroundings making it pass through the wet damp cooling pads.

Exchange of Heat: When the warm air passes through the wet cooling pads, evaporation occurs absorbing heat from the air. This ultimately lowers the temperature of the air. 

Passing of Cool Air: When the evaporation occurs the air cools down and the cool air is blown to the surroundings with the help of a fan. 

Continuous Process: The evaporative cooling process in an air cooler is a continuous process. This process continues until there is supply of water and air movement to facilitate evaporation. 

When to Choose Air coolers? 

When it comes to cooling appliances, there are several other alternatives available such as fan and air conditioners. It might be confusing to decide when you should be choosing between an air cooler and fan or an air cooler and conditioner. So, to help you figure out when to choose air coolers, here are a few things to consider,

Moderately High Temperature and Low Humidity 

Air coolers are most effective in spaces with moderately high temperatures and low humidity. It offers a more efficient cooling solution in such conditions. 

Outdoor or Semi Outdoor Spaces 

Air coolers can be effective cooling alternatives for outdoor or semi-outdoor spaces such as garages and workshops. It is more suitable for places where traditional cooling options are less effective.

Portable Cooling Requirements 

If you are looking for a cooling appliance that you can move from one place to another conveniently then air coolers can be perfect options. Other appliances such as ceiling fans and air conditioners need to be fixed at a certain spot. 

Wrapping Up 

Air coolers are one of the most common and efficient cooling alternatives that offer effective cooling. Although it is frequently used for cooling spaces, many of us do not know how do air coolers work. 

Air coolers work on the principle of evaporative cooling. It consists of parts such as a water tank, water pump, cooling pads, and fan to cool down the warm air from the surroundings. Air cooling in an air cooler involves processes that include water evaporation, circulation of air, exchange of heat, and passing of cool air.

Investment in a quality cooler not only helps you to cool your space but also helps you save costs in the long run. In this case, air coolers from Better Home Appliances are of high quality and budget-friendly.
