Analysis of energy characteristics of combined compression-thermoelectric refrigeration systems

Abstract
On account of low energy efficiency in maximum temperature difference mode, thermoelectric devices find limited applications as cooling and heating source in field of low temperature (-60°C and lower) and air-conditioning equipment. On the other hand, compression devices also have restrictions in obtained temperature difference in consequence of limited evaporation and condensation pressure, what leads to necessity of two stage compression in cooling circuits. So, the hybrid systems, which include thermoelectric block, can help to reach and keep the considered temperature level. This article is regarded to the problem of choose the optimum compression-thermoelectric devices schemes and to the determination of effective temperature modes of cooling equipment based on offered combination.
