Why is evaporative cooling important?
Furthermore, unlike mechanical cooling, evaporative cooling does not recirculate the warm, polluted indoor air, but ventilates 100% fresh, filtered, clean, and cooled air into a room or building. As a result, the indoor air quality substantially improves.
How does an evaporative cooling system work?
How do evaporative cooling systems work? In an evaporative cooling system, hot outside air is forced through wet cooling pads by means of a motor-driven fan. The cooling pads are moistened continuously by a water pump that delivers water to the cooling pads . The cooled down air is then blown into the building.
What is the difference between a one stage and a two stage cooling process?
We can see that a one-stage evaporative cooling process produces indoor air with a higher humidity content than a two-stage evaporative cooling process (~80% vs ~69%). Furthermore, the wet-bulb efficiency of a one-stage evaporative cooling process is lower than a two-stage evaporative cooling process (85% vs 114%). Finally, the required airflow to achieve the same indoor temperature of 25 °C at the same heat load (11 kW) is more than 3 times higher in case of a one-stage evaporative cooling process (20 960 m3 /h vs 6000 m3 /h). This implies that the moisture production of a one-stage evaporative cooling process is more than 5 times higher (118 L/h vs 22 L/h).
What is adiabatic cooling?
The sustainable solution for your industrial heat problem. Evaporative cooling, otherwise known as adiabatic cooling, works on the principle of water evaporation through which the air is cooled down to a comfortable temperature.
How does water evaporate?
During the evaporative cooling process, water is evaporated in a stream of air and passes from a liquid to a gas. This transition requires energy, which is extracted from the air in the form of heat. As a result of this process, the air is cooled down.
When was evaporative cooling first used?
Egyptian murals have been found, dating as far back as the year 2500 BC , that depict how porous clay vessels filled with water were placed beneath an air inlet to provide some cooling when the air passed through them.
How does evaporative cooling work?
Evaporative cooling is used in both biological and mechanical processes. Our bodies are designed to sweat to release heat and keep our body at its natural temperature when it gets too hot. Our skin releases sweat, which contains water. The water absorbs the heat from our skin and it eventually evaporates, taking the extra heat in our skin with it. This decreases our body temperature and keeps us from overheating in the summer.
Why does evaporative cooling take place?
The high humidity prevents the water from evaporating, and thus, no evaporative cooling can take place. Lesson Summary. In summary, evaporative cooling is the process of removing heat from a surface due to the evaporation of water. Water can absorb a lot of heat without changing phases, allowing it to remove heat from the surface it is on.
Why does sweating keep you cool?
You get into your apartment and, even though you might not have air conditioning, you start to feel cool and might even get the chills. Why does sweating keep us cool, even in warm temperatures? The answer is evaporative cooling, the process of liquid water evaporating from a surface, which decreases the surface's temperature. When sweat evaporates from our skin, it usually leaves us feeling cool. The droplets of sweat on the person's arm in the image below help to regulate his temperature:
How does water affect body temperature?
The water absorbs the heat from our skin and it eventually evaporates, taking the extra heat in our skin with it. This decreases our body temperature and keeps us from overheating in the summer. Air conditioners use evaporative cooling to decrease the temperature inside a building.
What is the process of water evaporating from a surface that decreases the temperature of the surface?
The answer is evaporative cooling, the process of liquid water evaporating from a surface, which decreases the surface's temperature. When sweat evaporates from our skin, it usually leaves us feeling cool. The droplets of sweat on the person's arm in the image below help to regulate his temperature: 3:46.
How does an air conditioner work?
It is also important for regulating the temperature of our environment through the use of evaporative coolers, better known as air conditioners, which work by pumping warm air into the air conditioner and filtering it through a pad soaked with water, which can absorb heat from the air and evaporate.
What happens if a nuclear power plant is not properly cooling?
Without proper cooling systems, nuclear power plants overheat and a nuclear meltdown occurs; radioactive material can escape into the environment. Evaporative Cooling Problems. Evaporative cooling only works if the water can evaporate into the air. Air has a maximum amount of water it can hold. This is called humidity.
Why is Water Used?
There are two things required to operate an evaporative cooler: A power source and a water source. The power source is obvious.
How Much Water Is Used?

The air is expelled out of the front of the evaporative cooler via fan or blower or into ductwork to travel throughout a larger home.
How to make an evaporative cooler more efficient?
Here is how to make an evaporative cooler more effective in five steps: “Warm-up” your evaporative cooler – Give the machine time to circulate some water through the moisture pad before turning on the fan. Allow about 15 minutes of warm-up time for maximum efficiency.
What is the purpose of a fan in an evaporative cooler?
Most evaporative coolers either have a fan or blower that can pull air into the system and blow it across the moisture pad. A moisture pad – This can be in the form of many types of media.
What is a moisture pad?
A moisture pad – This can be in the form of many types of media. It holds water and allows air to be passed through it. A water reservoir – The moisture pad must be moistened in some way. Many models have a pump that keeps the water in the reservoir moving, so the pad stays moistened.
Do evaporative coolers have an air filter?
An air filter – This feature is not present on all models, but many evaporative coolers have an air filter that has to be maintained separately from the moisture pad. These components work together to cool the air it is bringing into your home. The following steps are the basic aspects of a working evaporative cooler:
How does evaporative cooling work?
As air comes into contact with water, it absorbs it and becomes damp air or humid air. The amount of water that the air can absorb depends largely on how much water is already in the air.
What is the difference between an evaporative air cooler and an air conditioner?
One of the major differences between an Evaporative Air Cooler and either a Portable or fitted-system is that evaporative coolers do not have exhaust hoses or outside condenser boxes. They are also different from Air Conditioners in that they do not provide “refrigerant air” but rather provide “cooled air”.
How much cooling does a gallon of water produce?
An important point to understand is that the temperature of the water does not have any real effect on the cooling produced by the evaporation process. If you were to throw a gallon of water at 50°F on a warm pavement of say 90°F, it would produce 9,000 BTUs of cooling. If you were to throw a gallon of 90°F water onto the pavement it would produce 8,700 BTUs of cooling which is only a 3% difference. Imagine being sprayed with water at either of those temperatures on a hot day; as it evaporated off your skin you would feel much cooler.
What does relative humidity mean?
Remember the action of evaporation is the cooling power behind Evaporative Coolers. We use the term “relative humidity” when describing the amount of moisture in the air. The “sponginess” of the air changes according ...
Why does humidity affect water?
If the air is warm it becomes more spongy and can therefore hold more water. Because of this we must describe the level of humidity as relative to the temperature because this affects the ‘sponginess’ or absorbability of the air. Therefore, a room at 50% humidity will hold more water at 80°F than at 50°F.
Is evaporative cooling more efficient?
It is more effective in drier climates and can be used for everything from residential homes to large buildings such as warehouses and shops etc. Evaporative coolers are a very effective, economical and environmentally friendly method of cooling.
Can evaporative coolers be used in a closed area?
It is important to note, however, that there are restrictions as to the appropriate uses for Evaporative Coolers. For example, they must not be used in a closed and unventilated area because they rely on a flow of fresh air to enable the process to work.
