The major difference between AC and evaporative air cooling systems is that AC uses air and heat to cool the air. A cooler only needs to power two components, a water pump or a fan. It is essential to maintain the coolness of the air and keep the pads hydrated.
The cooler is also known under the following names: Evaporative Air Cooler, Swamp cooler, or Desert cooler.
Evaporative cool air is similar to wind running across a lake. The cost of refrigerated air conditioners is higher than evaporative coolers, which produce 100% fresh filtered cool water at a fraction of the cost. This makes it the most economic and viable option for cooling large areas. There is no need for you to close your doors or windows. Doors and windows that are left open work better.
How Does A Evaporative Ac Cooler Work?
The principle of evaporation is the basis of an Evaporative Cooler. When hot air and water are brought into contact, water evaporates. Each cooler is equipped with large cooling pads. The cooling pads are covered with water. A water distribution system distributes water evenly over the surface to ensure that the entire surface is thoroughly wetted. As the hot, humid air passes through these pads, some heat is absorbed by the water as it evaporates. The cool, fresh air is then delivered to the building.
The air is naturally cooled by natural evaporation. The pads filter out dirt, pollen, and other contaminants which can trigger asthma and hay fever. The result is cleaner, cleaner, and fresher air.
Evaporative Cooling’s Principles
When water evaporates, energy is lost and the air temperature drops. When it comes to evaporative cooling systems, two temperatures are crucial.
Dry Bulb Temperature
This is what we refer to as air temperature. It is measured using a regular thermometer and exposed to the atmosphere stream.
Wet Bulb Temperature
This is the lowest temperature possible with any evaporative system that achieves 100% efficiency
The potential for evaporative cooling is measured by the difference in wet-bulb temperature and dry-bulb temperatures when considering water evaporating into the atmosphere. The relative humidity can be calculated from the dry and wet bulbs. If relative humidity and dry-bulb temperatures are known, the psychometric chart can determine the wet bulb temperature.
Research has shown that productivity and attentiveness drop as temperatures rise. Comfortable is vital, regardless of whether you are at work, at church, at home, or the office. Evaporative air coolers provide 100% fresh, cooled, and continuous air while conventional air conditioning uses closed systems that constantly recirculate the same stale conditioned air. The constant air movement of an evaporative cooling system moves hot air out. This removes dust allergens and smoke odors from the air while replacing them with cool, fresh air.
Evaporative air conditioner is a better choice than refrigerated systems for their environmental benefits.
Evaporative cooling systems use only a small fraction of the electricity used by comparable refrigerated systems. An air cooler uses as little as 90% electricity compared to refrigerated units.
This means that fewer fossil fuels, such as coal or natural gas, will be used in the production of electricity. Also, fewer infrastructures will be required for its generation.
Lower Peak Energy Usage
Lower Peak Energy usage could mean lower wiring costs, which can be used with solar power, and less demand for additional power stations.
NO PRODUCTION OFF Cfcs OR Hfcs
Evaporative cooling systems are free from harmful synthetic refrigerants. Many of the gases used to cool refrigerated units are powerful greenhouse gases such as hydrofluorocarbons, or chlorofluorocarbons that deplete the layer of ozone.
Less Green House Tanking
Evaporative air conditioners emit much less carbon dioxide (CO2) than the refrigerated alternative. Carbon Dioxide, by far, is the largest greenhouse gas.
