4.6 Ventilation circuits ALPHA (fig.10)
1) Lamp cooling:
Fan (1) produces the exhaust air flow (2), which
cools down the xenon lamp.
2) Test chamber (fresh air operation):
The ventilation circuit of the test chamber recei-
ves fresh air (3) through a filter mat (4) at the left
side of the unit. The quantity of fresh air is control-
led by an air inlet flap (5) and warmed up by a
heating system (6). The climatic fan (7) trans-
mits the air humidified by the humidifier via air in-
take tubes (8) to the test chamber (9).
In the ALPHA, air flows from the air duct at the
rear of the unit to the samples (10). A sensor (12)
measures the temperature and relative humidity
of the test chamber exhaust air (11) under per-
manent target/value comparison. Via an exhaust
air hose (13) the air is evacuated to the outside.

Contrasts to ALPHA:
In the HIGH ENERGY unit air is directed via an air
duct (1) from the top along the samples (2).
