How much air removes heat from the compressor room?
Determine ventilation from the heat that actually remains in the room, not automatically from motor power.

How we calculate
Method: Qair = Pheat / (ρ × cp × ΔT), cp = 1005 J/(kg·K), ρ = p/(RT) at the inlet temperature and 1.01325 bar abs.
Assumptions and limitations: Steady state, perfect mixing, no heat storage or solar gains. Add actual additional heat gains. The flow does not size a fan: resistance, replacement air supply and manufacturer requirements must be checked.
Method references- KAESER: Compressed Air System Installation Guide – ventilation and separation of cooling exhaust air.
Method version 1.0. Standard references verified in the ISO catalogue; the physical balances are not calculations prescribed by ISO. Before final design, we will verify actual operating and catalogue data.
