“…At the same time, in the ideal state, the semiconductor refrigeration system will produce Joule heating and Thomson heat when the Peltier heat is generated. When calculating the amount of cooling or cooling efficiency, Joule heat and Thompson heat are the two non-negligible heats [5]. And the thermodynamic model of ideal semiconductor refrigeration cycle is shown in Figure 3.…”

Abstract. With the development of society, people's requirements on the comfort of environment have been further improved. The semiconductor refrigeration technology, with the increase of material merit, has been greatly developed and widely used in civil and military fields. This paper, starting from the Peltier effect, first of all analyzes the influence of optimal coefficient and temperature difference on semiconductor refrigeration system in two kinds of extreme conditions. In addition, the curves of various factors on the semiconductor refrigeration are determined, which intuitively reflect the effects of various factors on the semiconductor refrigeration and their relationship. Secondly, based on the simulation results of the thermodynamic model, the impact of various factors on the semiconductor refrigeration system is simulated and the temperature change in a small range of space is determined. What's more, the impacts of various factors on the semiconductor refrigeration is summed up, and optimized suggestions are put forward. The study results showed that the performance of semiconductor refrigeration system is influenced by many factors. Through the study of effects of various factors on the semiconductor refrigeration, the temperature changes of semiconductor refrigeration in space are simulated, which can provide technical support for the development of semiconductor system.
