Evaporative Cooling Unit – What It Is and How Does It Works

When it comes to some of the popular systems to provide cooling, then evaporative cooling units are also a popular choice. This form of cooling actually differs from the AC systems, which will use vapor-compression or even the absorption refrigeration cycles. As evident from the name, this type of cooling system works on the evaporation process. This type of cooling uses water that will absorb a relatively larger amount of heat for evaporating. The temperature of the dry air can easily drop through the phase transition of the liquid water to its vaporized option. The cool air from the evaporative cooling unit uses less energy when compared to refrigeration. In some the dry climates, evaporation air cooling has one added benefit of conditioning surrounding air. It comes with more moisture, designed for providing the comfort of building the occupants. Thus, it prevents dehydration and maintains the moisture level in the atmosphere.

The Principle to Follow:

Before you end up purchasing the evaporative cooling unit, it is mandatory to understand the principle of evaporating cooling. These cooling systems use evaporation as a major principle for providing cooling for buildings and machines. A Cooling tower is used for discharging warm air from cooling tower to the atmosphere through water cooling.

Step by Step Working of Evaporative Cooling Unit :

• The system gets heat from the sun shining on the building. The air handlers pick up the heat and transfers this heat to the refrigerant with the  help of heat exchangers.
• The heat then boils the refrigerant from liquid and transforms it into vapor forms. Cooling tower water is then circulated through a heat exchanger where the refrigerant vapor is then condensed, and the heat gets transferred to the water.
• The main purpose of the cooling towers of the evaporative cooling unit is to cool down the warm water as procured from heat exchangers so the system can reuse it again and again.
• The cool water will then loop back right at the beginning of this evaporation procedure. It is used then for absorbing more heat from the current heat exchanger. This way the system start reusing the same coolant to provide cool air.
  

Eco-Friendly and Cost-Effective in Nature:

Amongst the several benefits that an evaporative cooling has to offer, it is also an environment-friendly option.

• Lesser power consumption  is one of the befits which this system has to offer.
• It helps in translating to some bigger savings on the current utility costs. It will address a lesser impact on the bank account but also work great for the said environment.

• Unlike some of the other air conditioning sections, the evaporation coolers don’t use CFCs. The latter is harmful to the environment and it also increases the greenhouse effect. Hence it becomes important that you must choose evaporative coolers which doesn’t make use of CFCs.
• On the other hand, these cooling units are simple, effective to use and mainly in areas with a hot and dry climate.

Check out the Brands:

Whenever you are trying to purchase the evaporative cooling unit, it is always important to choose the best brand. Going through all the available brands first and then finally choosing one is the clever point for you to address. However, always try to check out the money you are comfortable to spend on the evaporator based cooling units before making one final move at your service. You can scour the internet for various options and then make a decision about buying the one.

Conclusion
The above-mentioned benefits makes evaporative cooling a positive investment and a great way to combat the heat.
