Thermoelectric Cooling (Peltier/TEC) & COP Formula Guide
Thermoelectric coolers transfer heat via the Peltier effect. Cooling capacity (Qc) and Coefficient of Performance (COP) depend on current, voltage, and delta temperature.
1Thermoelectric Equations
Power Consumption (Pin) = Voltage (V) × Current (I)
Coefficient of Performance (COP) = Cooling Capacity (Qc) ÷ Power Input (Pin)
Frequently Asked Questions
Peltier COP usually ranges between 0.3 and 0.8 depending on delta-T. While less efficient than vapor compression, TECs provide silent solid-state cooling.
