Difference Between Direct And Indirect Evaporative Cooling

Direct vs Indirect Evaporative Cooling: What is the Difference

Evaporative cooling is one of the greener cooling techniques for utilizing water as its refrigerant. To evaporate 1kg of water into an atmosphere, 680W of energy is required. For steam humidifiers, this energy normally comes from the electricity or gas being used to boil the water. However, for direct evaporative cooling , this energy is taken from the air in the form of latent heat, which results in a drop in air temperature.So for every 1kg of water evaporated into an atmosphere, 680W of evaporative cooling is achieved,making it most energy efficient compared to other modes of cooling.

It makes the technology environment-friendly and provides lots of benefits to the users. Evaporative cooling works on the principle called evaporation of water. By this principle, water takes heat from the incoming air and then evaporates to cool down the air to produce the cooling effect.

As the entire process consumes low energy, it becomes the cost-effective and energy-efficient method to keep the space cool in dry and hot climates. Generally, a blower or fan is used to draw the warm air from outside and pass it via wet pads to evaporate. Two different techniques are used in evaporative cooling – direct and indirect.

Scroll down your eyes to know the significant Difference between direct and indirect evaporative cooling and its uses in detail!

Direct evaporative cooling system

It defines the system where the incoming outside air is blown across a wet cellulose , the moisture present on the surface evaporates and reduces the air temperature. In this method, all the cooling effect is obtained by the evaporation of water and this cool air is transferred to to the space being cooled. The cooling efficiency of this system increases with increase in ambient temperature and decrease in relative humidity levels.

Indirect evaporative cooling system

In this system, the stream of air first passes through an air to air heat exchanger . It has alternate channels of polymer plates. In one channel water is sprinkled from top and hot water enters in counter flow arrangement form bottom side .the water evaporates and cools the incoming air.This cooling effect is transferred to other side by conduction.The other side of the surface as well as the atmospheric air passing through adjacent channel is cooled without adding moisture content,since it is being cooled without coming in direct contact with water. The attached video will make things clear.

Direct vs. indirect evaporative cooling

You will now get an idea of evaporating cooling and its two significant techniques. The following section will explain the potential differences between direct and indirect evaporating cooling. These techniques are often called two stages. It gives you an in-depth understanding of the working of evaporative cooling and makes the right purchase decision.

  • An indirect evaporative cooling system works similarly to a direct cooling system. But, the significant difference lies in the heat exchanger used in indirect cooling  to cool the air supplied to the space.
  • In the direct cooling system, moisture is added to the air stream supply for achieving cooling, but no moisture is supplied to the air stream in indirect evaporative cooling.
  • The efficiency of the direct evaporative cooling system is 90%, whereas the indirect cooling system has 60-70%.
  • An indirect cooling system is perfect for areas where the outside temperature is hot and humid . The direct cooling system provides a stronger cooling effect in the areas where air is hot and dry ..
  • Indirect evaporating cooling demands two fans instead of one so it consumes slightly more electricity compared to a direct cooling system. But It provides better temperature drop in dual stage .
  • Compared to direct evaporative cooling, indirect offers enough cool air to the interior space with desired low humidity levels.

Bottom line

Now, you will understand the major Difference between direct and indirect evaporative cooling systems. In a direct evaporative cooling system, water evaporates into the air stream through the engineered pad to offer the cooling effect.

But, an indirect evaporative cooling system uses evaporating water to cool the airstream passing through the heat exchanger. Therefore, it maintains constant humidity in the treated air. Both have specific benefits and drawbacks. You must consider those elements before making any decision.

Usually, Evapoler’s direct and indirect evaporative air cooling systems are sustainable and energy efficient as it uses nature’s own way of cooling.

Overall, with evaporative cooling technology, you can meet a wide range of your cooling needs within your budget.

How do evaporative cooling systems work?


Evaporative cooling is also known as adiabatic cooling. The evaporative cooling systems will work on the principle of water evaporation, where the air is cooled to a comfortable temperature. It is one of the cooling and ventilation techniques that use water as a refrigerant. During the evaporative cooling process, the water evaporates in the air stream and turns from liquid to gas. This transformation requires energy extracted from the air in the form of heat as a result of this process, the air is cooled.

What is evaporative cooling?

Simply put, evaporative cooling can be described as a process that heats water that converts it from liquid to vapor because cooling through evaporation is a natural occurrence. The most common example is perspiration. You could say that evaporative cooling provides cooling on the same principle as perspiration.

When dry, hot air enters the refrigeration unit. It goes through a dampened cooling pad. The water will evaporate, and the heat will be absorbed. As a result, lower-temperature air is pushed into the house. The combination of moving parts reduces air temperature and circulates cool, 100% fresh air throughout the house.

Evaporative Cooling System: How It Works?

In an evaporative cooling system, the hot outside air is forced through a wet cooling pad using a motor-driven fan. The cooling pad is continuously humidified by a water pump that delivers water to the cooling pad. The cooled air is blown into the building, and the exhausted air is cooled to between 60 and 90 % of the wet bulb. Depending on the efficiency of volatile substances, the air coming out is 10 to 15 °C cooler but has higher humidity.

On the other hand, two-stage evaporative cooling offers up to 114% efficiency of wet-bulb. This results in a temperature drop of up to 17 °C, and due to the lower temperature therefore, it has 60% less moisture than the direct evaporative cooling process.

Why will evaporative cooling important?

An evaporative cooling using indirect/direct system is a sustainable and highly energy-efficient cooling solution. This provides a comfortable and productive climate for the manufacturing plant, distribution center, and office building. The evaporative cooling process in indirect/direct cooling uses 10% of the energy required for mechanical cooling. While providing the same temperature as traditional mechanical cooling systems, evaporative cooling systems also do not circulate warm and polluted indoor air. Unlike mechanical cooling Instead, 100% fresh, filtered, clean, and cool air is ventilated into the room or building; as a result, indoor air quality is greatly improved.

Best Evaporative Air Cooler


If you are you looking for a way to beat the heat, if you don’t have a central air conditioning system in your home or are looking for an eco-friendly or affordable option, you might wonder if an evaporative air cooler is right for you. You can understand how an evaporative cooler works is an important part of figuring out if an evaporative cooler will work in your home. If you are new to evaporative cooling, there are many things to learn. Here’s everything you need to know about how evaporative coolers work and how to decide if you should invest in an evaporative cooler.

What is an Evaporative air cooler?

An evaporative cooler is one type of air conditioner that works by harnessing the power of evaporation to cool air temperature. The water evaporates and changes from liquid to gas. During this process the particles with the highest energy will release water first and causing the temperature to drop. This is why a damp cloth on your forehead feels good on a hot day; it lowers your head temperature as the water evaporates.

The same scientific principles apply to evaporative cooling when it comes to the air in your home. The evaporation process can help reduce air temperature. You have probably experienced this for yourself if you have ever steamed to cool the air around you on a hot summer day. Evaporative air conditioners use the same concept but add technology to make this process more efficient. And it doesn’t get messy more than just spraying the room with water and hoping for the best.

How does an evaporative cooler work?

Evaporative cooling systems use basic evaporation and automate it to lower the air temperature in your home effectively. The unit typically consists of a fan, thick plate, water reservoir and additional controls for fine-tuning the results. The fan draws hot, dry air into the machine and through the cooling pad. These thick sheets absorb water from the reservoir and are multi-layered to increase the surface area. When hot air passes through the sheet, Water molecules on the surface will evaporate. This lowers the air temperature inside the cooler, often up to 20 degrees. The fan then blows cool air into your room, where you can enjoy the cold on hot days.

The best evaporative air cooler can have other parts. Many people use air filters and pads designed to improve air quality by reducing allergens and mildew growth. This is an important consideration for people with allergies or other respiratory problems. A water pump is not necessary, but it can increase the absorption efficiency of the cooling pad. Some models have the option to add ice packs to cool the air further than the fan blows into the room. It has different fan speeds, a Vibration function and the remote control is a useful feature too.

Best Evaporative Air Cooler:

The best evaporative air cooler has two main advantages over traditional air conditioners: energy efficiency and sustainability. Both are due to the fact that evaporative coolers use much less electricity to operate. In fact, a standard air conditioner can use up to seven times as much electricity as a watt.

On the other hand, standard air conditioning systems rely on the compressor to push the liquid refrigerant into a smaller space and then move through a heat exchanger to extract heat from the air. This process requires a lot of electricity to be successful. Using less electricity with evaporative coolers means reducing your carbon footprint and paying less for utilities. It should also be noted that evaporative air cooler use water only and do not contain chemical refrigerants that are harmful to the ozone layer.

Efficient tips for getting the most out of your evaporative cooler:

Open window:
Unlike a standard air conditioner, you try to keep your home sealed to keep cool air. Evaporative coolers need consistent fresh air. The exhaust fan allows warm, dry air to be drawn into the chiller for rapid evaporation. An open window also allows moisture and airflow from the chiller to escape.

Restore water resources:
If you have not used the cooler for a long time, Rinse and clean the reservoir to avoid mould and mildew growth in wet areas.

Correct sizing of your chiller:
Before you buy, be sure to check the recommended square meter fee that the cooler covers and measure your room to place the cooler properly.

What is an Air Cooler, and how does it Work?


What is an Air Cooler?

Air coolers are also known as evaporative or purified coolers, and it cools the atmosphere by evaporating water. When air flows through water, some particles on the water’s surface will be blown away. These particles carry heat with them and cool the air. This is the main mechanism behind air coolers. With the help of this article, you will learn about how does an air cooler work.

The working principle of an air cooler:

Air coolers work on the evaporative cooling principle, where water evaporation is used to cool the air. One simple example of evaporative cooling is sweating in humans. When the sweat begins to evaporate, it draws out excess heat absorbed by the skin in the form of gas which results in the cold in the case of cold weather.

Many air cooler today come with dedicated ice trays, which helps to cool the water. This results in fast and powerful cooling. The best thing about using an air cooler is that you can leave the doors and windows partially opens to ensure fresh air is always circulating.

How does an air cooler work with water?

Sweating also acts the same way: water particles on the surface of the skin take away heat as it evaporates and cool the skin. These chillers are known to use 75% less energy compared to central air conditioners.

Evaporative coolers come in a variety of styles. Fine droplets are sprayed into the air and then blown out by a fan in some way because the water in this mist consists of small droplets. It will evaporate easily and absorbs heat from the air. Alternatively, the air is created to blow through the wet material. It can be blown through fine mesh or a wet sheet, for example. This wet material cools as it evaporates and cools the air.

Depending on the temperature, the air can only retain some humidity. When the temperature is higher than that amount, Water will begin to condense out of the air at the same rate as it evaporates. This leads to effective protection against evaporative cooling.

How will the Air Cooler work without water?

Direct evaporation is used in residential shift chillers and industrial conditions. This is explained by a metal or plastic inner box with side vents. Centrifugal fan or blower drives air, and the water pump will wet the evaporative cooling pad. The cooling system may be installed on the roof, exterior wall or window of a building nearby the exhaust fan through the vents on the side of the machine and the moisture-proof sheet to keep it cool. The heat in the air evaporates the water from the plates, which are continuously re-plated to continue the cooling process.

These two working principles will help to clear confusion about how does an air cooler work.

Incredible benefits of using an air cooler?

Energy efficiency: On average, air coolers use ten times less energy than conventional air conditioners, guaranteeing a significant reduction in consumer electricity bills. Some air coolers today also come with inverter technology which further reduces energy consumption. This technology saves up to 50% of energy and electricity costs compared to conventional air coolers.

An added benefit is that the inverter cooler emits much less noise due to the electronically switched motor and makes working and joining your video calls easier and more enjoyable.

Capital and recurring costs: AC has pre-purchase and installation costs or operating and maintenance costs. So the air coolers are much cheaper than air conditioners.

Environmentally friendly: Unlike ACs that use harmful chlorofluorocarbons (CFCs), air cooler use a natural evaporative cooling process with no carbon emissions, which makes them an environmentally friendly option.

Air quality: The air cooler circulates fresh air as it draws hot air from the outside and cools it. In addition, the circulating air is filtered to be hydrated and easy to breathe. It also keeps your skin hydrated. AC, in turn, circulates the residual air in the room.

Installation and portability: Unlike an AC that requires professional installation and works as a fixed unit. But air cooler do not need to be installed. All you have to do is fill the water tank and plug in the power cord. Plus, the air cooler is portable and can be easily moved around.
