The efficiency of TEC's varies substantially depending on operating conditions. Treating them as if they had a fixed efficiency of 60% will not lead to accurate calculations of cooling performance.
Also, the current draw for a TEC is dependent on the hot and coldside temperatures as well as the voltage. TEC's do not behave much like a typical resistor.
