In order to find the answer of this question, we have to compare an Air Cooler with the most common and powerful cooling system which is an air condition. The difference between evaporative air conditioners and air conditioning is noticeable. Air conditioning appliances need refrigerants, such as Freon gas, to cool the air, using refrigeration cycles by vapor compression or absorption. Evaporative coolers, also called adiabatic Coolers, are devices that cool the air by evaporating water, using the large enthalpy of water vaporization, that is, the ability of water to exchange energy with its environment. From an ecological point of view, air conditioning, due to its refrigerant, is more harmful to the environment. Air Coolers are greener, using only water.
Evaporative coolers cool the air in the room and work best in open areas, while air conditioners cool the air and circulate it and work best in closed areas. Evaporative coolers are especially convenient in dry climates, where the air is hot and the humidity is low. Dry air temperature can be significantly reduced by evaporating water to steam. In very dry climates, Evaporative Air Conditioners have the additional benefit of conditioning the air by adding the humidity necessary for greater comfort for people and animals.
Working Process of Air Coolers
The basic principle of the best air cooler is the use of water in the air cooling process. The hot air from the room entering the appliance passes through the honeycomb cooling medium. The water is pumped from the tank and poured onto the honeycomb; this allows the cooling medium to absorb heat from the air, cooling and humidifying the environment. The already cold air is forced out of the unit with the help of a fan. This process does not require a compressor.
Basic Principle of Air Conditioning
Portable air conditioners work a little differently. The compressor, condenser and evaporator are housed in the same compact unit. The air is filtered, cooled and dehumidified in the same apparatus. These compressor-based refrigerant systems are air-cooled, which means they use air for heat exchange, just like a standard car or air conditioner. The system dehumidifies the air as it cools. A flexible outlet air hose sends the heat outside.
Where you should place your Air Cooler?
It is important to take into account the areas where you want to place the appliances to get the most out of the one you decide to buy. Coolers, for example, cool the air in the room and work best in open areas; while portable air conditioners cool the air and circulate it and work best in closed areas. Many of us make the mistake of not taking into account the climate of our city when choosing a cooling system for our home and it is one of the things that we must keep in mind the most.
Coolers are the best option if you live in dry climates, where the air is hot and the humidity is low. By working with water, they have the additional benefit of conditioning the air by adding moisture, which translates into greater comfort for people. Air conditioning usually make up about 5% of the energy bill. Air coolers that use water reduce energy consumption by up to 85% compared to air conditioning. For Indian weather and medium class people, Air Coolers are best option.
