With the warm weather upon us, cooling your facility efficiently and effectively becomes a top priority. The three most common industrial cooling solutions are air conditioning, evaporative cooling, and misting fans.  In this article, we are going to take a look at each of these cooling systems, compare some key advantages and disadvantages, and help you identify which industrial cooling solutions are best suited for which applications within your facility.


What are the main differences between these three types of cooling solutions, and which should you choose? Well, that all depends on several factors including cost, climate, and location.




Air conditioning:

The most versatile of the three options, but it comes with the highest equipment, installation, and running costs.

Evaporative cooling:

Ideal in environments/climates with low humidity, this method of cooling is less expensive than A/C and more environmentally-friendly.

Misting fans:

The most economical choice, and very effective at cooling people both indoors and outdoors, especially hot summer events, but they do require a water source.

1: Industrial Air Conditioning (A/C)

So, what’s industrial air conditioning (A/C)? Well, in layman's terms, it’s very much like the A/C you find in almost every modern residence these days, but operating on a much larger scale. While the design and scale of these systems has changed since its inception, the basic principles and challenges of indoor climate control remain the same.

Let's examine the main components of an air conditioner. These elements work in a seamless, continuous cycle, with the refrigerant being the heart of the air conditioner. This chemical compound changes from a gas to a liquid and back again, absorbing and releasing heat during the process, which is crucial to your air conditioner's function.




This highly efficient cooling system usually comes in three main designs:




Ducted Air Conditioning also known as “central A/C” or “central air” or “split system”, ducted systems run flexible or metal ducts under the floor or in the ceilings of your facility, expelling the air through strategically-placed vents throughout the building. These vents all connect to one main air conditioning unit (comprising an evaporator, compressor, and condenser), and are controlled by a thermostat which these days are often app-enabled).

A return vent or grille collects the circulated air, and the system also employs filters to clean the air of particulates which need to be changed at regular intervals.

The key advantage of this system is uniform temperature control throughout the space; however, depending on the size and scale of your facility and the way the heat affects different parts of the building, a ducted air conditioning system may not be the most efficient solution.

If you’re dealing with severe temperature fluctuations between rooms, floors, or sections of a facility, a ductless system may be more suited to your specific cooling needs.




Ductless Air Conditioning Often referred to as a Mini-split system, this more tailorable solution, available in single-zone and multi-zone options, usually consists of a condenser or compressor that sits outside the property, with a sleek air distribution unit (or units) mounted on an interior property wall. There is also conduit/ducting used to connect the condenser to the air distributor.

By far the most energy-efficient way to cool rooms without ductwork, the multi-zone split air conditioners are an excellent and affordable option for many facilities. Precision inverters allow these systems to reach the desired temperature faster, which reduces energy costs, and there are many BTU cooling options and sizes available.





Portable Air Conditioning Finally, for even more flexibility and control, portable air conditioning units are an ideal option. These can work as standalone systems to control individual spaces, or you can use them in conjunction with a ducted or ductless system as supplemental climate control for spaces that can get hotter than the rest of the building. If you have a ducted system with some troublesome hot rooms, a portable A/C is an excellent way to provide cooling comfort without having to strain or redesign your existing climate control system. There are many options available to you, which you can find more about right here.


 2: Portable Evaporative Coolers (AKA Swamp Coolers)

If you are located in a low-humidity area, an industrial portable evaporative cooler could be the best way forward for your facility.

Evaporative coolers move air, via a blower, through water-soaked pads. This water in the pads evaporates, reducing the air temperature by up to 20°F. This option is also health and climate friendly, as breathing moist air is better for the body and this system doesn’t use chemical refrigerants or pollutants.

Due to the way they are built and maintained, they can cost about half as much to install as central air conditioners, and use around one quarter of the energy costs. They do take more maintenance though, and again, are only useful in areas with low humidity. Why? Well, the system relies on there being less water in the air than in the water-soaked pads. If there is already moisture-dense air to deal with, the effectiveness of the unit is reduced drastically, to the effect that in high humidity the cooling effect is almost nonexistent. 

As with many industrial cooling options, you are not limited to one specific type of evaporative cooler. Choose from either portable or window units, each coming in a range of sizes and prices to fit any budget. In either case, outdoor venting is required to channel heat away from the building.


3: Industrial Misting Fans

Finally, when your team is working outdoors, or you are hosting outdoor events that need to be cooled in extreme heat (think weddings, festivals, car shows, open-air concerts, after-work parties and so on), misting fans are the ideal and affordable option to keep employees and guests comfortable throughout the day.

As the name suggests, misting fans require a water source. Tankless misting fans pull the water from a source like a garden hose, which is a great “set it and forget it” option. Misting fans with tanks give you greater freedom on where to place the unit(s), but you do have to remember to refill the water throughout the day.

Either way, the fans pull the water supply and release it through vents in the fan, which combined with the wind generated by the fan produces a natural cooling solution (in much the same way that the human body cools itself by using sweat).

Misting fans come in a wide variety of sizes (including water tank sizes) and power options, and are both energy-efficient and affordable. They can also be brought in and out of storage as needed, making them excellent to have on site so they can be used whenever the heat is on. Some come with oscillation, most come with several speed settings so you can adjust the amount of cooling to perfectly accommodate all in attendance.

While these three industrial cooling options are most common, there are many ways to cool your facility, employees and guests which you can find right here at GI.
