Some Aspects of Peltier-Cooler Optimization Applied for the Glove Box Air Temperature Control 2006-01-2043

Peltier cooler usage for air temperature control in space and medical engineering is considered in this paper. The Bradford experience of Peltier unit application in cooling devices integrated in Glove Boxes is generalized. Examples of already existing for space applications designed devices, which use thermo-electrical principle for thermal control, are shown. Simplified engineering methods, which have been proven to be effective in practical applications, are given. For Thermo-Electrical Unit optimization the appropriate computer program has been developed. It has been shown that the optimal condition of power supply of the Peltier elements, integrated in the system (having Water Cold Plate, Air Heat Exchanger etc.), does not coincide with its own optimal condition. Besides the optimal power supplies voltage, there is the optimal amount of Peltier elements, if the heat exchangers characteristics are already known (i.e. the Heat Exchangers operational mode, boundary conditions and dimensions are limited with system requirements). The application of own software and software of the Peltier manufacturer is discussed. The results of a diagnostic experiment are shown also using correlated PC-model.
