The significance of air-conditioned homes and offices cannot be overstated. Humans are adversely affected by high-temperature conditions in a variety of ways. In general, it causes discomfort and can prevent someone from getting enough sleep or relaxing. As a result, the use of cooling machines has become necessary. Air coolers are an excellent way to beat the summer heat on a tight budget. The air cooler evaporates water present in the storage tanks, which are then delivered to us as cooled air.
Although it is a fantastic device, there are numerous other essential factors to consider when shopping for an air cooler. When we use a machine instead of nature, we gain both benefits and drawbacks. Today, we will look at the advantages and disadvantages of using an air cooler. But, before we get into the advantages and disadvantages of air coolers, let’s take a look at how an air cooler works.
How Do Air Coolers Work? Where Do They Work Best?
An air cooler operates on the direct evaporative principle, which uses water evaporation to cool the air. Water trickles over an absorbent yet porous pad in one of the most popular designs. At the same time, a powerful fan flows back air through the pad and into the room. The moisture on the pad vaporizes, removing heat from the air.
The fan or blower distributes the chilled air through a duct system or directly into the house through a vent. Aside from the fan, the only active part is a pump that keeps a steady flow of water over the pad. Some models lack a pump entirely instead of relying on a reservoir that the user must physically refill.
The most suitable conditions for evaporative cooling are when the climate is dry and hot. An air cooler can reduce the temperature by 11 degrees Fahrenheit if the ambient air temperature is 50 degrees Fahrenheit and the relative humidity is 10%. However, if the humidity is 90%, it will only reduce the temperature by 1 degree Fahrenheit, hardly noticeable. Dry, desert-like areas are ideal for air coolers. They simply add to the humidity in high regions while providing a minimal cooling advantage. Now that we know how an air cooler works, let us see some air cooler pros and cons.
Advantages of Air Cooler
During the hot and humid summer months, most people use air coolers to stay cool in their homes or offices since they are practical and cheap (Most air coolers cost under 10000). But the list does not stop there. The advantages of an air cooler are discussed further below.
1. Prevents Dehydration And Heat Strokes
Long periods of exposure to extreme heat can result in dehydration. It is because high temperatures cause excessive sweating and cause your body to lose water. Air coolers reduce sweating, which decreases the chance of water loss and dehydration. Excessive heat can also cause heat strokes. Its because extreme heat can affect the body’s ability to regulate its temperature. Air coolers lower the temperature of the air, which can aid in the prevention of heat strokes.
2. Helps Reduce Asthma and Allergies
Many people ask, “Will air cooler cause asthma?” The straightforward answer is no; in fact, air coolers help asthmatic patients. The air we breathe can be filtered and disinfected by air coolers. Clearing pollen and dust and preventing mildew and mold growth can help reduce the risk of asthma attacks and allergies. Mold exposure is one of the leading causes of asthma attacks, allergic reactions, and other respiratory problems.
3. Improves Quality Of Air
Air coolers can enhance indoor air quality and create a much healthier environment. It is due to their ability to filter out pollen, particles, and other irritants in the atmosphere. Air coolers can control the growth of moisture and mold by reducing humidity.
Disadvantages Of Air Cooler
Air conditioners have the advantage of increasing solace during hot weather, but they can also have several disadvantages or side effects of air coolers.
Air coolers can be pretty noisy. It has two segments: the fan or blower that circulates the air, and The other is the water engine, which is used to circulate water. The fan and the water motor both make a lot of noise. It is because all of the machine’s components are housed in a single unit. To reduce noise, place the air cooler outside the window.
2. Not As Powerful As Air Conditioners
In terms of cooling capacity, air coolers are not as effective as air conditioners. A swamp cooler or evaporative cooler cannot reduce the ambient temperature as effectively as the vapor pressure of a refrigerant-based air molding unit. In most cases, an air cooler will only cool a small area.
3. Daily Change Of Water
Every day, the cooler’s water must be changed. If this is not done regularly, bacteria, algae, slime, and other contaminants can grow in the water. If this bacteria-infected water is not changed on time, it will make you feel sick. We also prefer cold or chilled water when the temperature is exceptionally high. In this situation, cold water will eventually turn hot, necessitating another water change. Changing this water is a laborious task. Also, we need to change the water in gallons depending on the size of the cooler.
4. Humid Conditions Affect Efficiency
As we already know, air coolers operate on the evaporation principle, which converts water droplets into gas. Air that contains too much moisture in humid weather, causing evaporation to be slow or non-existent. As a result, the air cooler fails to perform optimally and becomes merely a fan. If you live near coastal plains or in areas with heavy rainfall, purchasing an air cooler is pointless.
5. Stagnant Water For Mosquitos
Mosquitoes are known to breed in stagnant water. The storage tank inside the cooler serves as an excellent breeding ground for these mosquitos. Coolers help mosquito populations to increase, putting your health at risk. You must change the water daily to avoid this.
Now that you’ve learned the advantages and disadvantages of air coolers, you’ll be able to decide whether or not to purchase one. Depending on your requirements, an air cooler can be used for both personal and commercial purposes. Furthermore, you should always buy high-quality air cooler brands; lower-quality brands have very few features and several drawbacks.
