Why simulate with CFD?
Hand calculations give volumes and pressures. CFD shows where air and smoke actually travel, for example around columns and beams, so jet-fan positions can be corrected before installation.
Engineering
HVAC & Smoke-Control Engineering
Heat-load, airflow and smoke-control calculations, CFD simulation, ventilation control and commissioning, with fans and control panels supplied by Powersense.
01Overview
Supply and engineering from one team
Powersense supplies fans, smoke-extraction units and control panels, and engineers the system they serve: duty calculation, CFD verification, control scenarios and measured commissioning. Heat-pump and VRF concepts are developed as part of the mechanical design.

02Scope and process
Engineering scope and deliverables
- 01
Design criteria and heat load
Indoor conditions, occupancy and ventilation rates follow EN 16798-1 or ASHRAE 62.1, and cooling and heating loads are calculated for each zone.
DeliverableDesign criteria sheet, heat-load summary - 02
Airflow and duty point
Airflow, duct pressure loss and fan duty point are calculated, with filter loading and noise limits taken into account.
DeliverableDuct calculation, fan selection sheet - 03
Smoke and heat control concept
Smoke extraction, make-up air and escape-route protection are defined to the EN 12101 series and the fire-safety concept of the building.
DeliverableSmoke-control concept, scenario matrix - 04
CFD simulation
Airflow and smoke movement are simulated in the real geometry to check jet-fan positions, dead zones and smoke dilution.
DeliverableCFD report with velocity and temperature plots - 05
Control and automation
Detector signals, fan starters and dampers are integrated in a control panel that runs the ventilation scenarios and interfaces with the BMS.
DeliverableControl narrative, panel drawings, I/O list - 06
Installation support and commissioning
Airflow is measured and balanced against the design, and each scenario is tested together with the fire alarm and recorded.
