Ventilation Assessment for a Fitness Room

Client: MQA Navia

The client required an assessment of indoor air quality and CO₂ dispersion within the fitness area of a gym. This enclosed space had high occupancy levels and significant ventilation demands. The objective was to verify whether the existing air renewal system was adequate and to identify potential areas with elevated CO₂ concentrations.

PROJECT SCOPE

The project was developed in two main phases:

· HVAC Duct Network Analysis:

The airflow distribution within the HVAC system was analyzed to identify areas with excessive pressure losses and potential flow imbalances.

· Indoor Airflow Analysis:

CFD simulations were used to evaluate airflow distribution throughout the room, identifying areas with poor air renewal and increased CO₂ concentrations.

RESULTS & CONCLUSIONS

The HVAC duct analysis revealed recirculation zones and significant pressure drops, causing imbalances in system regulation. Since the installation was already operational, modifying the duct layout or replacing high-loss sections was complex and impractical.

As a solution, local restrictions were introduced at supply outlets to adjust the required airflow rates in each area. CFD simulations made it possible to determine the exact level of adjustment required for each diffuser, eliminating costly trial-and-error interventions.

Additionally, a detailed analysis of CO₂ concentrations (ppm) and air changes per hour identified areas with inadequate ventilation. Based on these findings, diffuser settings were adjusted to increase fresh air supply in the most critical zones, resulting in a more uniform airflow distribution and a significant improvement in indoor air quality.
