Goldeye CL-033 TEC1 example
This example explains the functionality of the single-stage TEC1. It is shown in
The Goldeye CL-033 TEC1 has four temperature setpoints:
•
+5 degrees Celsius,
•
+20 degrees Celsius (default),
•
+35 degrees Celsius, and
•
+50 degrees Celsius.
It can achieve a maximum temperature difference of 25 kelvin between housing
and sensor.
As a result, the CL-033 TEC1 switches to the lowest setpoint it can reach, which is
at +35 degrees Celsius, and keeps the sensor at that temperature.
For this example, it is assumed that during operation, the case temperature of a
Goldeye CL-033 TEC1 has leveled at approxi48 degrees Celsius. Thus, the
minimum sensor temperature the TEC can reach is +23 degrees Celsius. It cannot
reach the default setpoint at +20 degrees Celsius.
Goldeye G-032 Cool TEC2 example
This example explains the functionality of the two-stage TEC2.
The Goldeye G-032 Cool TEC2 has three temperature setpoints:
•
-20 degrees Celsius (default),
•
-5 degrees Celsius, and
•
+10 degrees Celsius.
It can achieve a maximum temperature difference of 60 kelvin between housing
and sensor.
For this example, it is assumed that during operation, the case temperature of a
Goldeye G-032 Cool TEC2 has leveled at approxi38 degrees Celsius.
