About evaporative air coolers

Air Coolers 

Yeah, yeah, we all like to relax on the beach getting tanned all morning. I think we can all agree not facing a pile of snow covering your car in the morning feels pretty great, if it ever happen in Dubai. Not covering yourself with 3 different sweaters feels just as great. I'm happy, you're happy, everyone's happy. The end.... NOT! The sun becomes so generous in the summer that it doesn't stop being so hot (not THAT hot!). Luckily, science bestowed us with air coolers to suit our needs. 

Evaporative air coolers are so cool, literally! What makes them so cool, you may ask, aside from being physically cool, is that they don't work like the other air conditioners. Just like their name states, they use water's fast evaporating property to their advantage. By providing a specific amount of heat energy to the water as needed to make it vaporize, the evaporative air coolers become efficient. Each vaporized water droplet cools the air around it significantly. Since dry air is easy to heat up or cool down, they need to use far less energy. But when it comes to moist air, it becomes beyond easy! 

Now many of you would mix up air coolers and air conditioners. They have a fine line of differences. Their advantages include: 
  1. Energy saving: With no compressor in the setup (like traditional A/C has), the energy consumption would be a fraction of what an air conditioner would.

    Portability: This paves way for people who travel frequently to embrace its grace. There would be no reason to book a room with an air conditioner when you have something handy up your sleeve!  
  1.  Ease of installation and maintenance: These naïve air coolers do not require much and give so much! Being mechanically inclined may be a plus since you may be able to install its equipment yourself at lower cost while refrigeration equipment won't be cheap and requires professional skills to install. 
  1. Ventilation of air: The room gains a healthy lung, literally! Since the air flow rate is set at such parameters. A pad contained exclusively within an air cooler is used to pass air through it. This pad works like nostrils and filters out many air contaminants. I guess that's one way of gaining inspiration from things! 

Their disadvantages would include: 
  1. Performance: Lacking the technical design like refrigerated air conditioners doesn't allow air coolers to work better. High humidity in air may cause trouble for them with no dehumidification, unlike air conditioners that use their equipment to remove humidity. 
  1. Comfort: The air supplied by air coolers contain up to 80-90% humidity and this can cause reduced evaporation rate from nose, skin etc. Alas, nothing is flawless. 
Air coolers in UAE are also used in industries, factories and warehouses. Industrial air coolers are very common and in some cases, necessary. Such cases would include meat sections in supermarkets where cold temperature is required. In addition to that, customers who experience air cooling in a store are more naturally attracted to visit the place again, since stores need that strong efficiency provided by air coolers. 
Indoors aren't the only place where there needs some cooling in Dubai, such as street festivals, concert events, grilling or even camping. If the air outside isn't extremely humid, outdoor air coolers may save the day. Coming with stylish exteriors, they help keep you and your customers or guests refreshed and at ease. In addition, outdoor air coolers also help repel mosquitoes. They pull this off by creating such an air flow rate that it proves to be troublesome for these nasty bugs to hang around. 
There are times when a specific part of a room needs consistent temperature instead of the whole room due to high cost of those pesky air conditioners. It is then at this time spot air coolers sweep in. Being easy to transport room to room, they prove their worth quite amazingly. Spot cooling is cost efficient as well as area efficient, meaning it is used to obtain cooling in the exactly right spot while being cheaper. 
Pretty cool, right?!
