# Thermoelectric cooler operating-point screening
# Scope: Supplied operating-point cooling capacity, power and hot-side resistance; no TEC curve solve.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

cooling = 20 W
electrical = 30 W
hotResistance = 0.5 K/W
ambient = 25 degC

rejection := cooling+electrical [W]
cop := cooling/electrical
hotTemperature := ambient+rejection*hotResistance [degC]

check hot side temperature budget: hotTemperature <= 60 degC

scenario alternative: cooling = 16 W
