Evaporative coolers use special cooling media called evaporative pads. They aid in water evaporation. Water is circulated through the cooler unit around the cooling pads’ positions, keeping them constantly wet. Air is sucked into the cooler unit through the cooling pads. The water on the cooling media evaporates, cooling the air.
1. Water pumps circulate water from the water basin up to the top of the cooling medium, keeping it wet.
2. The cooling media cools the cool air by the running fan.
3. Water is evaporated as the air passes through the media. This is how the cooler cools the intake air.
What Cooling Effects Can Evaporative Coolers Deliver?
The natural science of evaporative cool is dependent on the nature of the process. Evaporative cooling’s cooling results will depend on two variables: outside relative humidity and outdoor air temperature.
Evaporative coolers provide superior cooling performance in dry conditions with low relative humidity. This is because the cooler the air, the more water can be evaporated into the atmosphere. Additionally, the cooler the air that remains after this process is complete, the greater the amount of water that evaporates into the atmosphere. Evaporative Coolers perform best in hotter, drier environments.
Evaporative coolers can deliver air that is up to 10 degrees Celsius colder than the outside temperature, in the best of conditions. The Evaporative Cooler can take air that is 38°C outside and cool it to 28°C inside. This is in ideal conditions, where the outside air is dry and hot.
Evaporative Coolers Are A Common Use
Evaporative coolers are suitable for cooling semi-enclosed areas to open spaces. They are commonly found in industrial applications like factories, warehouses, and workshops. These coolers can also be found outside commercial spaces, such as semi-outdoor shopping malls, office complexes, etc. In residential areas, smaller Evaporative Coolers might be found.
Waterline Cooling evaporative Coolers have been specifically designed to meet industrial-grade requirements. They are available in larger airflow capacities for large factories.
Evaporative Coolers Compared to Air Conditioning Systems.
Evaporative coolers cannot replace HVAC and refrigeration systems. Air conditioning produces chilled air at very low temperatures and uses coolants and refrigerants instead of Evaporative Coolers. Even though it can cool down very quickly, it consumes a lot more energy every day. Industrial applications are too expensive to cool entire warehouses or factories using air conditioning.
An evaporative cooling system costs about half as much to cool an area the same size as an HVAC system. This is just to give you an idea of how expensive it will be. Many factory decision-makers choose evaporative cooling because it is cost-efficient and can provide a work environment that is pleasant enough for a fraction of what air conditioning costs.
How Cool Is The Evaporative Air Produced?
Evaporative Coolers are often installed outdoors, so the cooling media can be exposed outside to ensure that it works effectively. The Evaporative Cooler has an axial fan that moves cool air inside. This fan is connected to a network of air conduits. An air diffuser or an air inlet mounted on the ducts delivers the cool air to the desired space.
Air ducts must have adequate insulation to keep heat from entering.
