Evaporative cooling: what it is, how it works and why to choose it

A natural and sustainable principle that allows you to cool the air in medium to large-sized environments, creating fatigue-resistant workspaces!

The evaporative cooling is the most sustainable, effective, and cost-efficient technological solution for summer conditioning of industrial warehouses and facilities.
It’s the ideal system in terms of comfort and performance, enabling you to establish a healthy and comfortable work environment for your employees even on the hottest days, all without wasting significant amounts of energy or contributing to environmental pollution.

Let’s explore how it works and the benefits it provides.

How does evaporative cooling work?

Evaporative cooling, also known as adiabatic cooling, utilizes a natural principle of thermodynamics known as “adiabatic transformation“.

The application of this principle allows for air cooling through a natural process: at the core of this system’s operation lies the phenomenon of water evaporation, which, combined with a simple ventilation setup, enables the cooling of air directed into the system and subsequently pushed into the treated space.

Water acts as a natural coolant in this process: individual units draw in warm external air, which passes through specialized water-soaked panels. The air is then filtered, cooled, and released into the working environment at more comfortable temperatures, managing to reduce the perceived temperature inside the facility by up to 5°C.

Let’s use a simple example to explain this phenomenon easily:
what happens to all of us when we go to the beach and come out of the water.

Despite how warm it might be, we feel comfortable, and if there’s a breeze, we might even feel cold. This is because the water on our bodies evaporates, releasing heat, regardless of the actual water temperature.

Based on this concept, we can understand another important characteristic of adiabatic cooling: for an effective sense of comfort, it’s not necessarily required to have cold water or to be connected to a refrigeration system. Having water at room temperature is enough.
This aspect is crucial because it allows us to save significant amounts of electrical energy that we would have needed if cold water had been necessary.

What are the advantages of adiabatic cooling?

The benefits offered by an evaporative system are numerous, not only in terms of comfort but also in terms of savings, health, and environmental protection. Let’s take a look at the main advantages together.

1. A healthy and ecological cooling system

The EUCOLD’s evaporative cooling system is entirely eco-sustainable, utilizing natural elements such as water and air, while also being energy-efficient and cost-effective.
Apart from providing a more comfortable and productive climate, it’s of paramount importance for the mental and physical well-being of employees as it ensures a constant exchange of air, hindering the spread of viruses that could potentially compromise their health.

2. Minimized energy consumption and operating costs

The purchase, installation, and maintenance costs of EUCOLD’s evaporative coolers are up to ten times lower compared to traditional air conditioning systems, resulting in considerably reduced economic and energy impact.

As we mentioned at the beginning of the article, the system operates through the thermal exchange between air and water.

This movement is achieved using one or two fans that draw in outdoor air, pass it through water-soaked evaporative panels, and then channel it into a ducted distribution system.

To limit electricity consumption resulting from the operation of these devices, EUCOLD’s coolers employ fans with specific fluid-dynamic characteristics and an innovative multi-speed regulation system.

3. Increased productivity, health, and safety

An evaporative cooling system is the best solution to combat summer heat, make the work environment more comfortable, and enhance the well-being of your employees.
Did you know that according to a study conducted by NASA, temperatures above 27°C could lead to “heat stress” among your employees?

This feeling of discomfort can result in increased distraction, lowered mood, and consequently, a higher likelihood of accidents.
With an evaporative cooling system, it’s possible to lower the temperature in the workplace by several degrees. This reduction has a positive impact on people’s well-being and their productivity.

This advantage not only has significant implications for production quantity, but even more noteworthy are the benefits related to workplace safety and the quality of work performed.

4. An innovative system for a comfortable work environment

Our range of EUCOLD adiabatic coolers consists of 6 models, allowing for air to be cooled from the sides, top, and bottom.
This 360-degree solution has been meticulously designed to offer greater installation and maintenance flexibility, while also minimizing energy consumption.
