What should you Look for when you Want to Buy Evaporative Coolers?

Thus, you have decided that you need an evaporative cooler to end your suffering from the scorching heat of the summer air. However, you cannot just pick the first air cooler you see on the product display of an appliance store or on the product catalog of an online store. A wide variety of evaporative air coolers are offered in the market, and some units may suit your specific cooling needs.
Before you start your
search for the coolest evaporative cooler in town, you have to make sure that the climate in your area is suitable for evaporative cooling. It is because evaporative coolers are ideal only in dry or low-humidity areas. If you live in a very humid area, an evaporative air cooler may only make the air more humid.

1. Size. The proper size of the air cooler for maximum cooling depends on the size of your home. Look for the CFMs of evaporative coolers and see which ones match the size of your room. CFM (cubic feet per minute) refers to the amount of air that an evaporative air cooler can distribute within your house. For a 1,500-square foot home, 6,000 CFM is necessary.
2. Cooling Effect. Choose an air cooler with a large cooling effect, even if you are going to use it to cool a small room.
3. Airflow. Check the cooler if it blows enough air. Good airflow is crucial to effective cooling because a great amount of air is needed to get rid of heat. If an air cooler cannot provide that, then it is not worth considering.
4. Noise Level. Evaporative coolers naturally produce noise during operation. If you prefer a noiseless evaporative cooler, opt for a large one that can blow a reasonable amount of cool air. However, they cost a bit more than smaller ones.

You can ,as far as the above-mentioned features are conconcerned,surely buy evaporative coolers which satisfy u as well as keep u in a cool spot in the heatweaving weather.

What is an Evaporative Cooler?

An evaporative cooler (also swamp cooler, desert cooler, and wet air cooler) is a device that cools air through the evaporation of water.

Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by employing water's large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor, which requires much less energy than refrigeration. In extremely dry climates, it also has the added benefit of conditioning the air with more moisture for the comfort of occupants. Unlike refrigeration, it requires a water source, and must continually consume water to operate.

In the United States, the use of the term swamp cooler may be due to the odor of algae produced by early units.Air washers and wet cooling towers use the same principles as evaporative coolers but are optimized for purposes other than cooling the air inside a building. For example, an evaporative cooler may be designed to cool coils of a large air conditioning system to increase its efficiency.

Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. In the United States, the western/mountain states are good locations, with evaporative coolers prevalent in cities like Denver, Salt Lake City, Albuquerque, El Paso, Tucson, and Fresno where sufficient water is available. Evaporative air conditioning is also popular and well-suited to the southern (temperate) part of Australia. In dry, arid climates, the installation and operating cost of an evaporative cooler can be much lower than that of refrigerative air conditioning, often by 80% or so. However, evaporative cooling and vapor-compression air conditioning are sometimes used in combination to yield optimal cooling results. Some evaporative coolers may also serve as humidifiers in the heating season.

In locations with moderate humidity there are many cost-effective uses for evaporative cooling,

in addition to their widespread use in dry climates. For example, industrial plants, commercial kitchens, laundries, dry cleaners, greenhouses, spot cooling (loading docks, warehouses, factories, construction sites, athletic events, workshops, garages, and kennels) and confinement farming (poultry ranches, hog, and dairy) often employ evaporative cooling. In highly humid climates, evaporative cooling may have little thermal comfort benefit beyond the increased ventilation and air movement it provides.
