Adiabatic Cooling

Known as adiabatic cooling or bioclimatic air conditioning, this simple ecological process uses hot outside air to transform it into cooled air.

The hot and dry air passes through a wet exchanger where it cools down. The energy required for the evaporation of water is extracted from the air.

This natural phenomenon is similar to what can be observed near water bodies where the temperature is lower in summer.

Operating expenses 6 to 10 times lower than traditional air conditioning

Installation

Benefits & advantages

Savings

Compared to traditional air conditioning, initial investment costs can be reduced by 3, and maintenance and operating expenses are 6 to 10 times lower than traditional air conditioning.

The device’s electrical consumption is negligible as it is limited to the operation of the fan. Water consumption can be sourced from rainwater harvesting. The module only uses the necessary flow for evaporation and mineral concentration cycles.

Environment

Compared to traditional air conditioning, electrical consumption is reduced by 10, and operational usage is reduced by 6. The reduction in ecological footprint is attributed to the low energy consumption of the devices.

Furthermore, this process does not use any refrigerant fluids (which have a detrimental effect on the ozone layer). Therefore, this solution is currently the best alternative, even for buildings with frequent openings and large volumes, as it does not lead to any overconsumption unlike more energy-intensive air conditioning systems.

Using adiabatic cooling (instead of conventional air conditioning) contributes to reducing the urban heat island effect.

Health

The system is automatically drained to control water hardness. The well-being and health of occupants are not affected because there are no microdroplets present in the device, which ensures the absence of legionella.

Maintenance

It’s a simple technology that requires easy and regular maintenance. Winterizing is the only recurring maintenance needed. Due to the low number of moving mechanical parts for its operation, the device is reliable, robust, and less prone to breakdowns. Only an electrical supply and a water inlet are required for its operation.

COMFORT

Adiabatic cooling introduces fresh air into your buildings while maintaining a comfortable humidity level.

Controls & Adiabatic Cooling Systems

The adiabatic cooling solution lowers the temperature inside the building. Managing this solution leads to better control of the installation. The equipment and sensors allow for managing indoor humidity levels, as well as indoor and outdoor temperatures. Based on information received from various sensors, the controller will trigger actions on the adiabatic system as needed.

An innovative solution for optimized production in Ardèche

The study deals with the implementation of an adiabatic cooling system in an 18,000 m² industrial building located in Tournon-sur-Rhône, Ardèche.

This site, the largest in Europe for the production of leisure vehicles with 13,000 units per year, was facing challenges of excessive heat affecting productivity and risking interruption of the production line. Traditional air-conditioning solutions were unsuitable and costly, especially as the site’s operations required doors to be kept open for the constant flow of goods.

The customer was looking for a cost-effective solution that would not disrupt the existing smoke extraction system, and would minimize interruptions during installation. Integration and control of the coolers via their Building Management System (BMS) was also essential.
