Evaporative coolers like the Luma Comfort EC110S brag about “Cyclonic Cooling Technology” but what is it?
Basically, it refers to the circular motion that the air is flowing in, which is determined by the combination of the movement of the fan head and the oscillation of the louvers.
This ensures that the air is more targeted so that you cool down faster.
Evaporative cooling units are different from traditional air coolers as they are designed to facilitate greater comfort for individuals living in hot and dry areas.
These systems chill air by evaporating the moisture that gathers, markedly reducing temperatures of the dry air, causing cooling effects that can be felt almost immediately.
Evaporative cooling units carry with them numerous advantages that you cannot gain from traditional airflow fans.
These cooling systems ensure:
- Energy efficiency
- Low maintenance costs
- Quiet operation
- Reduced operating costs.
Additionally, evaporative cooling units produce moist air that is ideal for those who suffer with allergies or asthma.
The technology applied in the design of an evaporative air circulator plays a vital role in its efficiency. For this reason developers like Luma Comfort are adopting and incorporating cyclonic cooling technology in the manufacturing of swamp coolers. This technology may not redefine the evaporative cooling process, but it definitely promotes efficiency in energy use and reduction of environmental pollution.
Cyclonic cooling in an evaporative cooler has the ability of freshening our air with moisture and particles with sizes not exceeding 10µm.
Evaporative coolers are also better for both your pocketbook and the environment. They are a natural source for cooling a home or business because it runs on water and not chemicals.
Therefore, with the targeted air flow of cyclonic cooling, evaporative coolers work even faster to get you cool in arid weather.
Direct Evaporative Cooling
The main function of the direct evaporative cooling system is to change liquid water in to a vapor.
The technique for doing this is to use an underlying heat of evaporation in order to reduce the temperature of the air.
- The total amount of energy within the air remains the same in this process.
- It will convert hot and dry air to cool and wet air.
- In order to evaporate the water, heat from the outside air is used.
- In order to continue the evaporation system, the air full of moisture has to be frequently freed to outside. Otherwise the entire system will stop because of the saturated air.
Indirect Evaporative Cooling
There are some similarities between direct evaporative cooling and indirect evaporative cooling.
The main difference is the type of heat exchanger used for the indirect evaporative cooling.
There will be no direct contact between the conditioned air and the cool, wet air, hence the term indirect. Most of the time the stream of the moist air is released outside.
It can also be used to reduce the temperature of some external devices like solar cells, as these are more competent in a cooler environment.
Two-Step Evaporative Cooling
The two-step evaporative cooling is done in two steps, which is where the name comes from.
- In the first step of a two-stage cooler, hot air is pre-cooled indirectly without the addition of humidity. It is done by passing inside a heat exchanger and it is cooled by desertion on the outside.
- In the second stage, the pre-cooled air from the first stage goes throughout a water-soaked pad.
- In this stage the air added extra humidity that makes it cool.
- In order to reach the expected cooling temperature, little amount of humidity is transferred because of the supply of pre-cooled air from the first stage.
In order to increase the overall effectiveness, either a direct or indirect cooling system has been combined with absorption air conditioning or vapor-compressions. These systems are called hybrid systems and are greatly effective in reducing the temperatures below the wet-bulb limit.
Cyclonic Cooling In General
While cyclonic cooling in an evaporative cooler give more targeted air flow, it is not an entirely new concept and can be found in other types of cooling appliances like fans. However, the idea of combining the targeted air flow of cyclonic cooling with the benefits of what an evaporative cooler can do is what Luma Comfort has patented in the EC110S because it is an idea worth patenting.
Advantages of Cyclonic Cooling Technology Verses Circular Air Flow
- Cyclonic cooling technology in an evaporative cooler effectively removes particles as small as 0.5µm because of the strong centrifugal force and minimal turbulence within the system.
- However, removal of particles largely depends on the moisture content of airflow.
- For efficient removal, the air flow from the evaporative cooler needs to be highly humid. A humid environment encourages entrapping of water-loving molecules and very minute droplets that cannot be centrifuged.
- In addition, the intense centrifugal force also ensures efficient removal and evacuation of micro-organisms from the air flow.
- This means that the air inside your house or business is free from health threatening microbes, helping those who suffer from allergies or asthma.
The cyclonic cooling technologies are much less expensive to install then the circular air flow systems. In fact, they can cost up to half the cost of a central air system. They are also less expensive to operate, costing users an 1/8 of that of a central system.
The power of airflow is what definitely sets cyclonic cooling apart from regular evaporative cooler operations. Though it is not groundbreaking, it is smart and worth a shot.
