摘要: Abstract A model of the behaviour a two-stage semiconductor thermoelectric heat-pump with external heat transfer is devised. Performance heat-pump, assuming Newton’s heat-transfer law, analyzed using combination finite-time thermodynamics and non-equilibrium thermodynamics. The analytical formula describing heating load versus working electric-current, coefficient performance (COP) electric-current are derived. For fixed total number elements, ratio elements top stage to also optimized for maximizing COP heat-pump. effects design factors on analyzed.
