IF you are getting ready for a new cooling season, there are a few things you need to know. First and foremost is that you need to have your AC unit inspected and cleaned before you start using it after the winter period.
However, if you don’t have an AC, or you are thinking about installing a new one, you may have come across different kinds of air conditioner units and something called air coolers. If you are unclear what air coolers are and if they are anything different from an air conditioner.
Air Coolers
Air coolers have the same function as air conditioners, but they achieve the goal in different ways. Air coolers function through evaporative cooling. In essence, hot air is blown through the air cooler which contains a wet membrane. This membrane cools the air down, and then the fans distribute the cooled down air.
The membrane of the air cooler is often made of wood wool or shavings of wood (also known as excelsior) which can trap a lot of water in them, and the water pump located above the membrane continually adds moisture when needed. More modern air coolers also use different materials like plastics and melamine paper which are more effective and durable than the traditional wooden ones.
However, using water to cool down the air means that the cooling range is limited and you may not be able to achieve the temperatures which are considerably lower than the ambient temperature. Furthermore, air coolers add moisture to the air, meaning that it may not be suitable for more humid climates.
Air Conditioners
On the other hand, air conditioners use a bit more advanced approach to cooling. Air conditioners contain a special fluid called the refrigerant. This gas has cooling properties when the pressure changes, which makes it suitable to cool down your home. However, that does make air conditioners a bit more complex than air coolers.
Blast Auxiliary Air conditioners need to have compressors to cool down the refrigerant and two sets of heat exchangers. The first heat exchanger is called the condenser and it is located in the outdoor unit of your AC. When the gas is sent from the compressor, it is hot and compressed. Once it reaches the condenser, it cools down significantly and it is ready to be transported to the indoor unit.
The refrigerant is released into the indoor unit through a small opening, which reduces the pressure, enabling the refrigerant to pick up the heat from the inside air. It is then transported back to the compressor and the cycle begins again.
Which One Is Better?
These two devices use different methods to achieve roughly the same effect. Which one you should get largely depends on what you are looking for. The climate that you live in can be a major influence on your decision.
Air coolers are better suited for dry regions since they add moisture to the air, whereas air conditioners function in all climate types. Typically air conditioners reduce the amount of moisture in the air, but thanks to the more advanced functions, they can supply additional moisture artificially.
If you are keen on keeping your windows and doors opened, air coolers are a better option, since air conditioners work best with closed systems and recycle the existing air. However, if you need to cool down your house by a considerable margin from the outside temperature, air conditioners are far more effective than air coolers. It is also fair to notice that the maintenance of cooling systems is more extensive than that of air coolers.
If you are looking to install a new air management system, you need to carefully consider what you really need and which of the two options suits you better.
