ActiveCool Temperature Gradient
It is important to understand the relationship between the three
temperature settings in the ActiveCool, enclosure and projector.
They are all different.
1.
The cooler sensor is in the cool air flow, and is used to regulate
the cooler cool air temperature
2.
The enclosure sensor is in the inlet fan box on the side of the
projector (under the projector in portrait enclosures). The
enclosure sensor is typically 6-7
°
C higher than the cooler
sensor.
3.
The projector inlet sensor is inside the projector inlet. It
typically reports temperatures 2-3
°
C higher than the enclosure
sensor.
This means that the cooler set point must be set approximately
10
°
C LOWER than the desired projector inlet temperature.
For example, for an inlet temperature of 24
°
C, set the cooler set
point at 14
°
C.
These values will differ in different site conditions.
