3 Cooling Systems To Include In Your Next Outdoor Event

When you’re planning an event taking place in sunny Singapore, the question of temperature control becomes of utmost importance. After all, your guests can’t focus on the event or have fun if they keep sweating all the time! Especially when it comes to events held in alfresco spots or dome tents, efficient cooling systems are usually a must-have. But what method shall you use to cool down your big event? There are several options, each with its advantages and disadvantages.

Read on to find out several ways you can cool down your event and the pros and cons of each method.


Outdoor Misting Fans

Misting fans are a popular option for outdoor events that require cooling down big spaces and crowds. If your event is held in an open-air tent, outdoor misting fans are the ideal cooling systems for you. They work similarly to air coolers that need a water supply to operate.

Outdoor misting fans are relatively simple devices. They have a simple fan as their base, and attached to it is a mister. The mister places water vapour in front of the fan, which is responsible for blowing the mist out over the surrounding area. The tiny droplets of water quickly evaporate in the air and pull the heat away from the immediate area to cool its air temperature. This entire process is called “flash evaporation.” It happens so quickly that the water vapour doesn’t even have time to reach you. Hence, you wouldn’t have to worry at all about your guests feeling sweaty. Since their cooling method doesn’t rely on cool air staying in one place, misting fans are considered the more efficient cooling option for events held in more open-air setups. They also take up less space than air or water coolers, even though they can keep a large area cooled just as quickly and efficiently as the latter.

If you’re an environmentalist who cares about energy efficiency, then you have more reasons to go for misting fans since they’re generally more energy efficient compared to air conditioners. For instance, a compact portable air conditioner usually consumes over 900 watts of power, while the largest misting fan may only use as low as 300 watts. Such efficiency will help keep your electric bills low without having to compromise the luxury of cooling your outdoor events during summer or any other season.

However, note that since misting fans use water droplets, it’s not advisable to use them in events involving delicate machinery or wood. Misting fans should not be used indoors, especially when the venue itself is humid. There’s a tendency for the water to not evaporate quickly enough in humid conditions, leading to a much higher humidity level than when the fans are turned off.


Portable Air Conditioners

If your event involves using delicate machinery or wood, then misting fans are not a suitable cooling method for you. Your best option would be portable air conditioners.

This type of air conditioner doesn’t use water and works the same way as built-in air conditioning: it sucks in the ambient air, runs it through a refrigerant that decreases its temperature and humidity, and pumps the air out again. In essence, the primary function of a portable air conditioner is to pull in the air in a room, condition it to a specific temperature by extracting the heat, and then finally release the cooled air back out. The refrigerant plays a crucial role in this process since it is used to cool the room down as the heat exchange medium. It’s cooled down after being compressed and then rapidly expanded. The cooled refrigerant then absorbs the heat from the room air. As it’s being compressed, heat is produced, which must be exhausted. Therefore, if you’re planning to use portable air conditioners for your event, you’ll need to find a place, such as an air duct, to expel the hot air.

Moreover, you’ll also need to calculate the size of your dome tent and determine your guest count before renting some portable air conditioners. Generally, one set of air conditioner is recommended for every 60 to 75 square metres of the venue. Knowing these details is very important, so you can ensure that your chosen cooling solution benefits all your guests. Aside from knowing your tent size and guest count, it’s also necessary to ensure that you have a good power generator for your event. Portable air conditioners are the most energy-intensive of all the cooling methods on this list. As mentioned, one portable air conditioner can use up to more than 900 watts of power. Nonetheless, this cooling method is also one of the most effective since one portable air conditioner unit can generally provide a 15 to 20-degree temperature drop. So, if your venue has an 80-degree Fahrenheit temperature, the air coming out of an air conditioner will likely be 60 to 65 degrees Fahrenheit. This makes portable air conditioners excellent for countering the humid Singapore weather.


Air Coolers

If you’re working on a limited budget and want a cooling solution that’s as quick and effective as air conditioners, air coolers are your best choice. Also known as swamp cooler fans or evaporative cooling fans, air coolers are less expensive than air conditioners, but they’re equally efficient at cooling down high square footage areas. Like misting fans, air coolers work using water, so they need a water supply equipped for them to operate. Once running, the fan used by an air cooler pulls moisture from the supply and through the fan itself. The water then reaches the fan’s blades, and once it does, the rotation breaks the water into mist composed of the tiniest water particles. Since the water particles are small, they immediately evaporate once they hit the air. During the evaporation process, the mist cools down the humid temperature in the air and ultimately makes a room cooler.

Of all the cooling methods listed here, air coolers can be considered the most environmentally friendly since they cause fewer carbon emissions than the other cooling devices. Compared to air conditioners, mainly, air coolers use much less energy. The rated power of one air cooler can be as low as 150 watts, which is relatively minor considering the cooling effect it offers. However, the downside to choosing air coolers as your event’s cooling system is that they’re less easy and flexible to set up, as they require connection to a water source. Moreover, since they work on the principle of evaporation, air coolers may fail to work in humid conditions where the air already contains excessive water droplets in gas form, thus making the whole process of evaporation slower or inadequate. And with slow or no evaporation, an air cooler will fail to work at its best.



When holding an event, one of the most important things to achieve is to make your guests feel comfortable. Whether your event is held in a small conference centre or a large dome tent in Singapore, ensuring your guests are comfortable is essential. And a large part of making your guests feel comfortable is keeping the venue at a reasonable temperature.

But that will prove challenging in tropical Singapore, which is why Nanyang Inc is here to provide you with efficient cooling systems designed to keep your event at a reasonable temperature no matter the weather!
