Hey everyone I was curious if you could help me. There maybe several questions in this so bear with me. Btw I am not an engineer so try and keep it simple please. What variables are needed to find how much a thermoelectric generator will produce let's say from 500 degrees one side and room temperature at the other? Can a generator be be cooled by and air refrigerant?

  • \$\begingroup\$ how many elements? what is the wiring size? \$\endgroup\$ – analogsystemsrf Oct 27 at 3:39

    \$\begingroup\$ Varies vastly with device. Specific datasheet thus helps heaps. Is that 500 C or F or ... . || Using ABSOLUTE temperatures (so 0C = 273K) Carnot efficiency = (Thot-Tcold)/Thot which is the absolute max efficiency attainable in theory and is unapproachable in practice. 50% of Carnot is good and less is usual. At dT of around 100C efficiencies in the 5-10% range are achievable . BUT see datasheet. \$\endgroup\$ – Russell McMahon Oct 27 at 6:05

  • \$\begingroup\$ Even here in the US, SI units are preferred for science and engineering. (Actually, for just about everything.) \$\endgroup\$ – Duncan C Oct 27 at 15:26
