Post installation real fire, cold smoke and hot smoke trials.It is possible to test an induction ventilation system in a number of different ways after installation has been completed.
Cold smokeThe simplest test uses cold smoke. A smoke machine can be set up at an agreed most critical location and will pollute the area with smoke for a pre-set time. The ventilation system will then be activated and can be evaluated as to its efficiency in removing the smoke over a set period of time. Using cold smoke can also identify any dead spots within the system.
Small tray fireThis test cannot evaluate the thermodynamic influences but these can be partly reproduced when a cold smoke test is combined with a small tray fire test.
Real vehicle fire
The most reliable test would obviously be when using real cars. However, this test is rather expensive, dangerous and can possibly harm the building. The thermodynamic influences are nonetheless fully present.
The results of a cold smoke test even when using a small tray fire to aid the simulation can differ dramatically when compared to a real vehicle fire.
Finally there is the hot smoke test. PVE have carried out these tests successfully for a number of years.
The thermodynamic influences are fully visible but the test will not harm the building as a clean alcohol based fire is used.
