Operating instructions XENOTEST BETA+

Functional description

5.4

Ventilation system

Fig. 11:

The XENOTEST BETA+ is air-cooled. The cooling system is supplied with two

different airflows: irradiator cooling

and test chamber cooling

Irradiator cooling:

A blower

aspirates the air

for the irradiator cooling at the air vents

at the right

side of the instrument. The air flows along the assembly duct and cool the electronic com-
ponents. Then, the air is routed through the external cylinder

of the irradiator unit and

cools the Xenon irradiators.
The heated air is carried off through the vent at the top of the device

and is aspirated by

a technical ventilation in or removed directly out of the laboratory.

Test chamber cooling in fresh air mode:

The air

for the test chamber cooling is aspirated by the blower

through the air filter

at the air inlet opening.

Depending on the present temperature in the test chamber

, the fresh air feed rating is

controlled using the motor-driven doors

and

The airflow is routed past the heating system

and heated to the required tempera-

ture. The humidification system

then mixes the air with humidified air and feeds the mixture

into the test chamber

. The humidification system removes air from the test chamber

through the inlet air pipe

The airflow

is distributed evenly around the sample turntable while temperature and

humidity are constantly measured by the integral sensor system

The used air is carried off through the exhaust air opening

and is aspirated by a technical

ventilation in or removed directly out of the laboratory.

Test chamber cooling in recirculating air mode:

In the recirculating air mode, the two air doors

and

are closed so that the airflow

is routed into the closed air recirculation system.
