Heater Function Test Description
The heater function test is used to evaluate the cooling and heating
performance of the two peltier elements.
When the test is started, both heat exchangers are cooled initially to 25 °C.
This temperature is held for 12 seconds, and then the setpoint is changed to
20 °C. The time required to reach 20 °C is a measure of the cooling efficiency
of the peltier elements. At 3.5 minutes, the setpoint is changed to 30 °C, and
both elements begin heating. The time required to reach 30 °C is a measure of
heating efficiency.
