Warehouse Airflow Application Reference
Planning guidance for warehouse airflow, HVLS circulation and separate ventilation responsibilities.
This archived page is an application reference for planning warehouse airflow. It does not include a project measurement record or a universal fan quantity rule.
What to review
Review clear height, rack geometry, occupied zones, loading doors, roof structure, sprinklers, lighting, existing HVAC and any required exhaust or local extraction before selecting equipment.
How HVLS fans fit
HVLS fans circulate room air toward the floor and help mix temperature layers in open areas. They do not provide outdoor air, remove process contaminants, dehumidify or replace a project-specific HVAC or exhaust design.
Combining systems
Evaporative coolers may suit selected dry-climate and open-air conditions after humidity, water, drainage and maintenance review. Keep comfort circulation separate from source capture and code-required ventilation.
Evidence status
The archived source does not provide enough project detail to verify temperature, energy or productivity outcomes. Request the project layout, model schedule, operating conditions, measurement method and dated records before using this page as a performance case study.
This case study is provided as a project reference. Conditions, equipment layouts, controls, climate, and measured outcomes can differ between facilities, so the example should be used to identify questions for a site survey rather than as a guaranteed result. Ask the RTFANS team to review the building geometry, operating schedule, existing HVAC or exhaust, electrical supply, and maintenance plan before selecting a comparable configuration.
When comparing the reference with a new facility, record the occupied floor area, clear height, roof and wall construction, machinery or storage layout, door activity, heat sources, humidity conditions, and the locations where people need improved comfort. Confirm whether the project needs general mixing, fresh-air replacement, source capture, spot cooling, or a combination. Electrical capacity, mounting structure, controls, water, drainage, cleaning, and access for maintenance also affect the final design. A site-specific review converts the lessons from this reference into a configuration that can be checked against local code, safety, and operating requirements.
