Evaporative Cooler : Concept
Utilizing water to cool the air has been a popular method practiced from ancient times. Evaporative coolers use the same method to make the air cooler. People in Egypt, India, and Arab countries would hang damp clothes to beat the heat. In this manner, they cooled the air coming in through the windows and doors by the method of evaporation. When hot air passes through wet clothes, the water in them Evaporatives and absorbs heat from the air causing a cooling sensation in the area. Evaporative coolers use this technique to cool the air in a room or outdoor space. It is a natural and efficient process for cooling air using the evaporation of water. In the past few years, Evaporative Air Cooler Dubai has been widely used to increase humidity. It is globally used due to the impact of global warming and climate change.
The principle behind evaporative coolers is that when water is Evaporatived, it absorbs the heat present in the environment, and as a result reduces the air temperature. A pump circulates water from the reservoir onto a cooling pad, which is completely wet. A fan extracts the outside air into the cooler and circulates it through the damp pad. The air cools down because of evaporation when it goes through this damp pad. The key to effective evaporative cooling is ensuring the saturation of each of the cooling pads during operation. It is also important to properly design the system fan and motor to deliver the appropriate airflow for the space.
Benefits of Evaporative Cooler
The Evaporative Air Cooler unit cools fresh air using only water. It does not make use of any chemicals and toxic substances. They use a small amount of electricity used by regular air conditioners that helps to save energy. The electricity used by the evaporating cooling units is the same even when it’s hot outside making these coolers different from normal air conditioners, which need more power according to the hotness of the weather. The working of evaporative coolers improves with the heat and saves more money than normal air conditioners.
For Large Industries, Commercial Kitchens, factories, warehouses, and other semi-open places where regular air conditioning is not possible or too expensive to install, evaporative coolers are a great option. These coolers don’t have compressors hence they keep the running cost very low. Evaporative coolers use the fresh air from outside and help to bring new air inside and push the old air through the ventilation systems. It maintains the air freshness in the room making it a comfortable space.
An Overview of Evaporative Cooling
Evaporation happens when the air is not fully saturated with humidity, The water absorption rate in air depends on the amount of water the air already contains. In evaporating cooling, the energy required to change water from liquid to vapor is generated by the air itself, in a process called adiabatic cooling. When the air passes through the evaporative cooler, it produces heat to transform water into vapor. This process reduces the dry bulb temperature of the air.
Dry Bulb Temperature
The dry bulb temperature is the air temperature measured using a standard thermometer. It is the temperature reported in daily weather forecasts and is sometimes referred to as the ambient air temperature.
Wet Bulb Temperature
The wet bulb temperature also uses a standard thermometer; however, a wet piece of cloth covers the bulb of the thermometer. As air passes over the wet cloth, the water in the cloth evaporates, drawing heat out of the thermometer. If the air is very humid (moist), only a small amount of moisture will evaporate from the cloth. This means the wet bulb temperature will only be a little lower than the dry bulb temperature. Conversely, if the humidity of the air is low (dry), the moisture will evaporate from the cloth quickly. This means that the wet bulb temperature will be much lower than the dry bulb temperature.
Dew Point Temperature
The dew point temperature is the air temperature where the moisture in the air begins to condense or change from a vapor to a liquid. In order for a surface to collect dew out of the air (like a glass of ice water or blade of grass), the temperature of that surface must be at or below the dew point temperature. The dew point temperature is always the coldest of the three temperatures.
Evaporation happens when the air isn’t fully saturated with humidity, meaning it’s under 100% humidity and can take in more water. The amount of water vapor air can hold varies, and how much it absorbs depends on how much water it already contains. Changing water from liquid to vapor needs energy. In evaporative cooling, this energy comes from the air itself, in a process called adiabatic cooling. As air moves through an evaporative cooler, it gives up heat to turn water into vapor. This process reduces the dry bulb temperature of the air.

Does Breezair provide 100% fresh air?
Breezair is based on the simple principles of evaporation, hot air from outside is pumped through wet pads called Chillcel pads. The water Evaporates when the air blows through the Chillcel pads, in this process, the heat in the air is absorbed which lowers the air temperature. Via a ducting system, the cool air is pushed outside by a fan. A patented centrifugal fan is used in Breezair cooling units. This fan can also be used in fan-only mode (no water) to blow fresh air through the vents. Another prominent point to remember is that the cooled air inside the building is not recirculated, so windows and doors should be opened for air to exit or the extraction fans should be installed. To achieve the highest cooling performance of any evaporative cooler on the market Breezair used advanced technology.
Benefits of Breezair Evaporative Coolers:
- Operating expenses are up to 87% less in comparison to traditional refrigerated air conditioning systems
- Utilizes only water for cooling, avoiding the use of chemicals.
- Environmental-friendly technology.
- Provides 100% fresh air, without any recirculation.
- Easy installation and maintenance
- Australian-made quality with global support.
- 25 years guarantee on plastic cabinets against corrosion
