3.2 Ventilation of the dimmer room
The dimmer room should be dry at all times, free from dust and ventilated in such a manner
as to comply with the following:
-
Relative humidity: 5% to 90% without condensation.
-
Temperature b 5 °C and + 35 °C (ideal: + 20 °C).
In order to size the air-conditioning equipment required for the dimmer room, refer to the
following dissipations:
-
Cabinet electronics including 150 W global value for CPU(s), PSU and fans
-
Thyristor modules:
o
4 x 3 kW modules : 37 W per dimmer (worst case)
o
3 x 5 kW modules : 69 W per dimmer (worst case)
o
1 x 10 kW modules : 170 W per dimmer (worst case)
-
Sinewave modules:
o
4 x 2.5 kW modules : 60 W per dimmer (worst case)
-
No-load losses of sine wave dimmers:
o
Sine wave dimmers have a no-load loss of approximately 4 W per dimmer.
In practice, you may consider a utility factor of 0.6: that is, on the average, 60% of the
dimmers are at full load, while 40% are off.
3.2.1 Example No. 1
A dimmer room with a EURODIM Twin Tech cabinet equipped with 128 thyristor dimmers of
3 kW and a second cabinet with 96 thyristor dimmers of 5 kW. The cabinets are fitted with a
back-up power supply for the processor unit. Utility factor = 0.6
1) Cabinet N°1
Electronics: 1 x 150 W
Dimmers 128 x 37 W x 0.6 = 2841 W
2) Cabinet N°2
Electronics: 1 x 150 W
Dimmers 96 x 69 W x 0.6 = 3974 W
ROOM TOTAL: 7115 W (1 W = 0.86 kcal/hour) or 6119 kcal/hour.
In this example, it will be necessary to evacuate approximately 7115 W of losses.
