All About Air Coolers: Working, Benefits and Types
Air coolers, also called evaporative coolers, are a highly effective and sustainable cooling solution that has gained popularity in recent years due to their low energy consumption and environmentally friendly features. Unlike traditional air conditioners, which rely on refrigerants that can be harmful to the environment, air coolers use only water and air to cool and humidify the surrounding space.
Air coolers are essential in areas where high temperatures and low humidity can cause discomfort and health problems. They work by drawing in hot and dry air, passing it through a wetted pad or membrane, and cooling it by the process of evaporation. This not only cools the air but also adds moisture to it, which can alleviate symptoms of dry skin, allergies, and respiratory problems.
How do Air Coolers Function?
Typically, an air cooler works in the following ways.
- A fan draws hot, dry air from the outside into the cooler unit.
- The air passes through a wetted pad or membrane, which is kept moist by a water pump or gravity-fed system.
- As the hot air passes through the pad, water from the pad evaporates into the air.
- Evaporation requires energy, which is taken from the heat in the air, leading to a drop in temperature.
- The cooler, humidified air is blown out of the unit and into the surrounding space.
What are the Benefits of Using an Air Cooler?
Air coolers offer a range of benefits owing to their ease of usage. Here are a few listed below.
- Energy Efficiency: Air coolers are much more energy-efficient than traditional air conditioners, as they use only water and air to cool the surrounding space. This means that air coolers use up to 75% less energy than air conditioners, resulting in lower electricity bills and a reduced carbon footprint. The power consumption of air coolers is 150-300 watts.
- Affordable: They are generally less expensive to purchase and operate than air conditioners. This is because they do not require refrigerants, compressors, or other expensive components. As a result, air coolers are a more affordable cooling solution for homes, offices, and other indoor spaces. Crompton offers a wide range of Air coolers under Rs 5000 and Rs 10,000.
- Environment-friendly: Air coolers are an eco-friendly alternative to air conditioning units, as they do not release harmful refrigerants into the environment. Instead, they use only water and air to cool and humidify the surrounding space, making them a sustainable and responsible cooling solution.
- Humidity Control: They are also effective in adding moisture to the air, making them an ideal solution for dry climates. By maintaining humidity levels, air coolers can alleviate symptoms of dry skin, allergies, and respiratory problems, as well as help to reduce static electricity.
- Easy to Maintain: They are easy to maintain, with many models featuring removable pads and filters that can be easily cleaned and replaced. It is easy and essential to clean the honeycomb pads in air coolers. Additionally, air coolers do not require complex installation, making them an accessible and hassle-free cooling solution for most indoor spaces.

1. Are air coolers good for health?
Yes, air coolers are considered to be good for health. They can help to improve indoor air quality by adding moisture to the air. This can be particularly beneficial in dry climates, where low humidity can cause issues such as dry skin, dry eyes, and respiratory problems. Air coolers can also help to reduce the risk of heat stroke and other heat-related illnesses during hot weather, as they help to keep the indoor temperature down.
2. Does an air cooler work in humid conditions?
Air coolers work best in dry and arid climates where the humidity level is low. In humid conditions, the effectiveness of air coolers may be reduced because the added moisture in the air may already be high. However, Crompton’s range of air coolers has a humidity control feature which helps in maintaining a sufficient level of humidity in the room.
