Abstract
A method of controlling a heat exchanger including thermoelectric coolers to maintain set point temperature of a chamber. The method includes receiving temperature data indicative of a temperature of the chamber and selectively controlling two or more subsets of thermoelectric coolers based on the temperature of the chamber. Selectively controlling the two or more subsets includes operating each thermoelectric cooler in a first subset at or near the point where the coefficient of performance is maximized (QCOPmax) by providing a current or voltage with amplitude corresponding to QCOPmax (ICOPmax, VCOPmax) when the temperature of the chamber is within a predefined steady state range including the set point temperature.
