Post by thread:[EE] BTU of a Peltier junction?

Was wondering if anybody knows of quick and dirty way to get an idea of how many BTUs a peltier device of a certain size is capable of? Not looking for any sort of precision, basically whether it's 1 or 10 would be enough. Thanks, TTYL ----------------------------- Herbert's PIC Stuff: http://repatch.dyndns.org:8383/pic_stuff/

If I remember rightly a BTU is 3.4W, so a 50W Peltier unit would be 170BTU. Cheers, Howard Winter St.Albans, England

Well my memory was sort-of there, but my typing was pants! (As has been pointed out off-list...) I reversed the ratio and omitted a dimension, so here goes again: 1 Watt is approximately 3.4 BTU/hr. I did the calculation correctly but omitted the time dimension again, so: a 50W Peltier would be about 170 BTU/hr. Hopefully that's it! Cheers, Howard Winter St.Albans, England
