Evaporative Cooler Buying Guide
So, you have finally decided to take the big step and purchase an evaporative air cooler. In this case, here are some aspects that you might want to consider:
6 Things to Consider When Getting an Evaporative Cooler
- Installation and Air Flow
Most of the time, a standard evaporative air cooler is installed on the wall or the roof since it sends the cool air downward – and makes the breeze feel all the more comfortable. However, there are some people that prefer the portable version that is placed near a window or anywhere else that they believe suitable.
Regardless of where you install the unit, make sure that you play it safe against leakage problems. These problems are more common with air conditioners – but if you are not careful enough, this can happen with evaporative coolers as well. If you are not certain how to install an evaporative air cooler by yourself, you might want to bring in an expert that knows precisely what they are doing.
They will know exactly where the air cooler should be installed so that the air flow is at the perfect level.
- Maintenance Level
Some air coolers were designed to be durable and sturdy – whereas others were made to be decorative and cheap. The former, however, is the type of cooler that you may want to invest in – mainly since it will last for longer.
These units are generally resistant to corrosion and rust – and their maintenance is usually fairly basic. This will serve their purpose of effectively cooling down your house for as long as possible – making them price-effective as well.
As mentioned, an evaporative cooler can either be installed on the ceiling or the wall – or it can be portable and movable from one room to another. If you have a bigger house with more rooms to keep cool at different times, then you might want to invest in a model that has portability features.
First, you should consider the size of the unit. If an evaporative cooler is very heavy, then it’s likely that you will not want to carry it from one place to another. Similarly, if the unit is very large, moving it around might be rather difficult.
Next, you might want to consider the accessories that add to its portability. Does it have caster wheels so that you won’t have to carry all the weight yourself? Does it have handles, so that you can lift the unit if the situation asks for it? These features are very important if you are planning to move the cooler very often.
When it comes to evaporative coolers, there are three ways in which these units can operate. The first is a vent-only operation, where the water pump remains inactive and only the cool air is released. In this situation, the air is not humidified – and it’s perfect for rooms that already have a normal humidity level. These units have an operation that is similar to a ceiling fan.
The other operations involve two different speeds during which the humidifying option is running. As a result, the first (dry) setting is the lowest cooling option, which is perfect for mild weather – whereas the next two are appropriate for the warmer summer days.
Some units also use air filters during their operation – but that is also optional. This filter will keep the dust particles and other allergens away from the air – making the air even more breathable for you.
Not every evaporative air cooler has this type of filter – so make sure that your does, if you really need it. Worst case scenario, you should check whether you can attach a separate air filter yourself or not.
- Energy Saving
When you are planning to use an evaporative air cooler throughout the summer, you can expect to have it running for a fair amount of time – particularly during the daytime. This can be fairly pricey unless you are using an energy-saving model. However, they don’t use more energy than a bathroom fan.
The right unit can help you save up to 25% on the energy bill – so make sure that you go for models that have an energy saving seal. Still, most units feature this option – and they are more energy-convenient compared to traditional air conditioning.
Prices can vary when it comes to evaporative coolers – and it mostly depends on the features that it was equipped with. Most portable coolers are fairly cheap, which is why they are generally the most affordable option.
You can find great evaporative coolers priced around $150 or right under $200 – but bear in mind that the less expensive it is, the more maintenance it might require every day. To get your money’s worth, you might want to invest in an energy-saving model.
The Science Behind an Evaporative Air Cooler
Evaporative air coolers are units that make use of the evaporation of water in order to cool the air down. The reason why this is effective is that water has a fairly large vaporization enthalpy, which permits a rather high absorption of heat.
First, if the air is already humid, the evaporative cooler will not work effectively. For it to do its job properly, the air will have to be relatively dry – and obviously hot.
To understand evaporative air cooling, you may compare it with a more natural process – which is sweating. Have you ever tried rubbing alcohol on your skin? It felt cold after that, didn’t it?
To put it simply, in order for the liquid to be transformed into gas, it will use energy (heat) emanating directly from your body. Once that energy is taken, you will feel that nice, cooling effect.
Evaporative air coolers work in a similar way – only instead of drawing heat from your body, it will draw the heat from the air. The cooler features a fan and a series of damp pads – as well as a few pumps to ensure that the pads retain their moisture.
The fan will draw the outside air into the unit and through the damp pads – turning the liquid into vapor by using the energy from the air. This is precisely why damp air will not work for this unit, because the air has to be hot and dry in order for the liquid to evaporate.
Through this process, the hot and dry air becomes humid and cool – which will eventually be circulated throughout the house. These evaporative coolers are also used as whole-house humidifiers, for instances where the temperature is alright, but the air is unnaturally dry.
Are Evaporative Air Coolers Energy-Efficient?
In an area with a fairly low amount of humidity in the air, an evaporative air cooler offers a natural – and at the same time, energy-efficient way of cooling down the house. This is mainly because this type of unit does not use any fancy systems that require a lot of energy.
Practically, an evaporative air cooler – also referred to as a swamp cooler – will rely on cooling the outdoor air by using water pads. The hot air will pass through these cold pads, leading to condensation and causing it to evaporate.
As a result, air that is cooler by as much as 40 degrees Fahrenheit can be released into the room. Through this process, the warmer air is also pushed through the window – causing the overall temperature to be more pleasant. This is particularly why you may want to keep your windows ajar when the unit is running.
Evaporative Coolers vs. Air Conditioners
Evaporative coolers are some of the oldest means of climate control that are still available to this day – and for some reason, they are the better alternative to air conditioning. Still, many people are confused as to how these two are different.
Both of these units use cool air to bring down the temperature in your home. However, the difference lies in the climate that you live in – as well as how much you are willing to pay in order to get results.
As mentioned, evaporative coolers use evaporated moisture to cool down the air in your home. It takes the hot air from your room, drives it through cold water pads, and delivers it back into the air, but colder and more humid.
Air conditioners, on the other hand, remove the heat from the room by using chemicals. This chemical is also referred to as “refrigerant gas,” which oscillates between gas and liquid form. Thus, they deliver cold air in the room, no matter if the outside air is humid or dry.
To make the differences easier to understand, here are some benefits and drawbacks that apply to both units.
When it comes to cooling the air from the environment, it is easy to understand why people prefer evaporative cooling to air conditioning. Not only is it more cost-effective, but it is also friendly on the environment.
Since air conditioners work better within enclosed rooms, they will recirculate the same chemical-treated air over and over again. The air may indeed be cooler than with evaporative air cooling – but the air quality may not be as high. Evaporative cooling can work with open windows – and even outdoors. So, the air will be fresh. This is why these units may also double as a window fan.
Granted, an evaporative cooler may not work as well if the humidity level is high in your space. In these circumstances, an air conditioning unit may be more effective, since it will not add moisture into the air.
Pros and Cons of the Evaporative Air Cooler
So, you have decided to buy an evaporative air cooler. For the most part, such a unit is a better alternative to the typical air conditioner, which removes the moisture from the air and cools it.
However, just like this unit has its own benefits, it also features some drawbacks. Here is a comparison.
- Highly energy-efficient
- It adds moisture into the air, making it perfect for environments where the air is dry and hot
- Air distribution is even, with the cooling system trapping the allergens in the process
- It requires little maintenance
- It does not use any chemical refrigerants
- The units are very easy to install
- Fairly inexpensive to purchase compared to air conditioning
- Not very useful in areas where the air is humid
- They build up minerals and salts that have to be cleaned
- Maintenance can be actually difficult if you install the unit on the ceiling
- They have to be continuously kept moist using water
- Overall, the pros seem to outweigh the cons when it comes to evaporative coolers – but you may want to keep every aspect in mind.
- Do evaporative coolers work in humid environments?
No, evaporative coolers do not work in humid environments. For the evaporation to occur when the air goes through the cool pads, the air needs to be dry and hot. Humid air will not be affected.
- How do you wire an evaporative air cooler?
If it’s a portable evaporative air cooler, then it probably needs no wiring. However, if it requires electrical installation, you may have to bring in a professional in order to install your evaporative cooler. Generally, though, you will have to connect the color-coded wires (white with white and black with black), and then connect the ground wire to the electrical box. You should also install a circuit breaker to protect the wiring before attaching it to the bus bar.
- How effective are evaporative coolers?
When it comes to cooling down the air, you can say that air conditioning has more cooling power than evaporative units. However, considering the price that you have to pay for the AC, evaporative coolers are more effective. The only time when evaporative coolers are rendered ineffective is if the humidity level is very high.
- How do you winterize an evaporative cooler?
To winterize the evaporative cooler, you have to cut it off from the water supply, drain it, and change the unit. You may also want to give it a deep clean before winterizing, to make the unit last for longer. The final step would be to install a cover, which may stop any outside air from entering your home.
