Air Cooler Vs Air Conditioner: Which One Is Better?

Are you looking for relief from blazing heat? Are you spoilt for a choice between an air cooler and an air conditioner? Don’t know where to begin? You don’t have to look any further!

Did you know that the year 2022 was declared the second warmest year? The temperature of the planet has increased by 0.32° F per decade since the 1980s! Quite serious, isn’t it? No wonder we feel warmer EVERY summer!

Thus, to beat the heat, a cooling system has become a necessity. However, the ongoing debate between an air cooler and an air conditioner had made this decision challenging.

It’s crucial to weigh the advantages and disadvantages of each alternative before deciding which is the most excellent fit for you. Thus, this article will provide an in-depth analysis of ten critical factors to consider when purchasing a cooling unit.

Before comparing them, it is crucial to grasp the differences between the two technologies, machinery, and operations.


What Is An Air Cooler?


Air cooler work on the principle of evaporative cooling. I am sure we are all familiar with evaporation. But did you know that the more the surface area, the more is the evaporation? Well, now you do!

In an air cooler, there is a water reservoir tank that must be manually filled. With the help of a pump, the water is subsequently pumped upwards and eventually distributed on the cooling pads. This pad’s surface area is larger to ensure a faster rate of evaporation.

When the hot air from the room comes into contact with these water-ridden saturated cooling pads, latent heat of evaporation occurs. The air loses its heat and gets evaporated. A fan is usually present that blows cool air continuously in the room.


What Is An Air Conditioner?

Air Conditioner

A cooling agent, often known as a refrigerant, is the magic element used in an air conditioner. Because the refrigerant has a low boiling point, it can quickly transition from liquid to gas and back to liquid to move heat.

In step one, the liquid refrigerant is evaporated. The cooling agent flows through a series of coils exposed to the air in your room. The heat from the air in the room will convert the refrigerant into gas. So, the refrigerant now has more heat than your room air! With the help of a fan, this cold air is blown into your room.

Step two is the conversion of the gaseous refrigerant back into its liquid form. Say hello to the compressor! The compressor increases the pressure inside the tube, eventually resulting in the condensation of the refrigerant. As it condenses, it loses heat. Where does this heat go? Well, another fan is responsible for transferring this heat outside the atmosphere via the external unit.


Difference Between Air Cooler And Air Conditioner

An AC or an Air Cooler is a source of sweet relief on hot days and nights! However, investing in any electronic device calls for extensive research! Wouldn’t you agree?

Thus, to save you some time, we cumulated a comparison between the two based on ten crucial factors.

1. Air Quality And Circulation

Air Quality

Now that you are familiar with the working principle, this factor will be more effortless for you to fathom. In an air conditioner, internal air is getting circulated in the room, i.e. the same hot air comes in contact with the coolant, and cold air is pushed out with the help of the fan.

Contrary to that, in an air cooler, evaporative cooling is used. In this process, fresh air is circulated in the room. We all know the importance of fresh air, hence the air quality of a cooler is better than an AC. Air coolers also add humidity and moisture into the air before venting out the cold air.


2. Portability

Without a doubt, air coolers are more portable than Air Conditioners. Coolers can be used in bedrooms, gardens, patios, outdoor gatherings, etc. AC units are installed permanently in the wall, whereas coolers can be moved conveniently from one room.

Air conditioners work best in closed rooms because fresh air will pressure the system, reduce the cooling ability, and eventually reduce overall efficacy. It can also cause the refrigerant to exhaust! Coolers work great even in open spaces without adding any undue pressure on the machinery.


3. Health Issues

Health Issues

Are you surprised to find this on the list? Let me explain. Working in AC can result in a mood upliftment and better work quality, but it can also cause severe health-related issues.

Have you ever felt thirsty after spending too much time in AC? If yes, allow me to explain why!

In contrast to the humid air produced by the air cooler, the air conditioner releases dry air. It causes a steady decrease in the area’s humidity, resulting in dry skin and eyes due to the evaporation of water from the upper layers of these organs.

Spending a lot of time in AC can also cause a headache. According to an article published in CNN, cold and dry temperatures can result in brain freeze followed by a migraine-like headache.

The mucus membrane in the nose is the body’s way of defending itself against pathogens that enter through the nasal cavity. However, nasal blockage and mucus drying occur as a result of dehydration. Thus, it can result in an overall increase in respiratory infections and diseases associated with the lungs.

There is a possibility that it can also worsen the symptoms of asthma. Since the same air is circulated, it can trigger an attack if an allergen is present in that air.


4. Environment Friendly

Environmentally Friendly

Are you a part of the environmentally-conscious clan? If the environment is vital to you, then an air cooler will be an eco-friendly option.

Firstly, the coolants in air conditioners are made from potent greenhouse gases like Chloro Fluro Carbons (CFCs). We all know how infamous the contribution of carbon dioxide is to global warming. Well, CFC-12 can retain almost 11,000 times more heat than carbon dioxide, making it more detrimental to the environment.

Additionally, the power consumption of an AC unit is more than a regular air cooler; thus, the amount of fossil fuels used to generate that power is also high.


5. Cost

Cost Factor

If you are looking for a low-cost solution, air coolers are a superior choice. A standard air cooler might cost around INR 10,000. An air conditioner might cost anything between INR 20,000 and INR 50,000.

Furthermore, because an AC consumes more power and thus more electricity, its operating costs are higher than an air cooler.


6. Maintenance


When you buy an electrical machine, you want to make sure it’s built to last and can work for long periods without needing to be serviced. A significant drawback of an air cooler is that it requires water to operate, so it must be refilled more frequently than we’d like.

The pump, fan and filters in an air cooler require fixing and cleaning once every two months. On the other hand, AC is not that demanding; it needs servicing once in six months.


7. Power Consumption

Power Consumption

An air cooler utilizes up to 10 times less energy than a conventional air conditioner. Power consumption by an air conditioner is heavy; thus, the electricity bill will also be high.


8. Climate

An air conditioner works very well in varying climates; the air cooler cannot function properly in a humid environment. Wondering why? The answer lies in the fundamental principle of an air cooler.

Evaporative cooling forms the basis of operation for air coolers. In this method, hot air is converted into humid, chilly air by the system; however, if the air is already saturated with water vapour, the rate of evaporation will be slower, resulting in a lower cooling impact.

Thus, if you reside in a humid climate, especially in coastal areas, you may want to invest in an air conditioner rather than an air cooler.


9. Noise


The buzzing sound traditionally associated with electronics has been eradicated thanks to advancements in air conditioning devices.

On the other hand, the air cooler produces noise because of the fan, which can be very unpleasant and disturbing.


10. Precise Temperature

Precise Temperature

Unlike Air Conditioners, air coolers cannot be programmed to function at a set temperature. Air conditioners come with a very user-friendly remote control that can help you precisely adjust the temperature, fan speed, swing, etc. Thus, the entire room will soon reach the desired temperature.
