What should you look for when you want to buy Evaporative coolers?

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.

Is An Evaporative Cooler Affordable and Energy-Efficient?

Is An Evaporative Cooler Affordable and Energy-Efficient?

These days, a lot of people are interested in evaporative cooling.  This is because an evaporative cooleris the most affordable and most energy-efficient cooling systems in the market today.
  But what makes evaporative coolers so affordable and energy efficient?  In order to find out, you would have to learn about how they work.
The mechanics of evaporative coolers are simple.  Basically, they use to main components in the cooling process: One is water; and the second is ventilation.  The first component is water.
Water is the main and most important part of this system.  Water is what makes the system cool.  In an evaporative cooler, water is chilled to about 5 degrees Celsius to 8 degrees Celsius.  As the name suggests, the water is evaporated and turned into fine vapours.  These, in turn, wait for distribution.  Here is where the ventilation comes in.  This usually takes the form of a blower or a fan.  Basically, it’s job is to distribute the vapours/cool air.  It doesn’t necessarily have to come into direct contact with the water, but it can too.

Evaporative Cooler Affordability

The reason why evaporative systems are so affordable is because they are not complicated mechanically and engineering-wise.  As you read above, the process and functions of an evaporative cooler is very simple, unlike traditional air conditioning units.  The reason why they are so energy efficient is because the work process is so simple.  Consumption is not measure in horsepower so that in itself explains everything.
Aside from the above advantages, evaporative cooler systems also have other more passive benefits. 
These types of systems are actually endorsed by Go Green campaigners.  This is because they are environment-friendly.  This is because they do not use refrigerants like CFCs and HCFCs for the cooling process.  Evaporative systems are the best─ affordable, energy-saving and earth friendly.

How Do Eco-friendly Evaporative Air Coolers Work?
  
AS The temperature of the remaining water drops , water is evaporated by the moving air.  Heat and energy is carried away by the faster moving molecules as water in the Air Cooler  evaporates.when the water evaporates the air near the surface increases its relative humidity and would slow down the evaporation if it was not blown away and replaced with air with a low relative humidity. The wind from the Evaporative cooler  fan increases evaporation and the rate the energy leaves the liquid water.


Temp
erature
is a measure of the energy in the water.
Since
the energy in the remaining water is dropping so too is the temperature of the remaining water. The same thing happens when you lick the back of your hand and blow on it. Top 7 Reasons to Purchase an Air Cooler Healthy life style Some types of air coolers, provide comfort to people with allergies and rest.It feels cool. This is how an evaporative cooler works. Water is pumped over porous pads where air is drawn through causing the water to evaporate and cool the air.

The result is that hot dry air is converted into cool moist air that is blown into a house for cooling. The process works best when there is a good flow of air and the relative humidity of the incoming air is below 30%. The efficiency (cooling effectiveness) goes down with an increase in the relative humidity of outside hot air.

In
many location where there is low relative humidity, one effective and inexpensive means to cool houses and businesses is with evaporative coolers. These use a fan to draw hot, dry outside air through water wetted pads where evaporation of the water cools the air. The cool moist air is then blown into the house and distributed for cooling.This experiment allows you to input the outside air relative humidity and the outside air temperature to obtain the temperature of the air that is blowing from the Air Cooler  into the house.

1.Healthy life style
Some types of air coolers, provide comfort to people with allergies and respiratory problems, as well as elderly people and children. Some swamp coolers are ideal for people allergies and other respiratory conditions. These such coolers draw exterior air into the building. Once inside, the air is cooled by evaporation and then circulated. This activity provides a constant supply of filtered, fresh air. This process is different from air conditioning units, which recirculate old air. Air coolers draw moisture into dry indoor air, increasing humidity while lowering the air temperature.
2. Environmentally Friendly.
Powered by the natural process of evaporation, evaporative coolers do not rely on extremely large amounts of electricity and chemical-based coolants, like Freon. Swamp cooler can provide energy savings and environmental benefits that can potentially lower your indoor air temperature by as much as 30 degrees Fahrenheit. Swamp coolers use about a quater of the energy used by an air conditioner or central air unit. Even the most complex residential swamp cooler system will uses significantly less energy than an air conditioning unit.
3. Save Money on Your Cooling Bill.
If your goal is to save money on your utility bills and reduce your cooling costs, then an evaporative cooler or swamp cooler may be for you. An evaporative cooler, such as the Schaefer Waycool 1/3 HP Oscillating Cooler uses only a quarter of the energy used by refrigerated air conditioners. the cost to operate an evaporative air cooler or swamp cooler is relatively cheaper than other cooling methods.
4. Affordable.
An air cooler costs only a fraction of the cost of a central air unit, ranging from $100 for a portable unit to $3,000 for a large industrial unit. Additionally,the low cost of installation, is about half the cost of installing a central air unit.
5. Easy to Install.
Because of its simple design, it is fairly easy and inexpensive to install an evaporative cooler.
6. It's Also a Humidifier.
Evaporative air coolers also have the ability to humidify dry air, as wet pads are used to cool the air. With this, you will be glad to know that your furniture and fabrics will be kept well moisturized too. This will definitely help maintain the durability and lifespan of your furniture.
7. Easy Maintenance.
Easy maintenance is one of the best reasons for getting an evaporative cooler. All coolers come with refillable water tanks which are easily accessible. A full tank lasts about 10 hours. If you require a longer operational period, consider an cooler with a hose connection which continuously supplies fresh water to the cooler. All air cooler filters can be removed and rinsed.
