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.

“…It does not support combustion, thus making it an ideal refrigerant in sea vessels until the CFC and HCFC became popular [5]. Montreal protocol being effective, CFC is banned and HCFC also needs to be eliminated at the earliest [6,7]. Satish and Govind (2011), reported a detailed study of Vapor absorption system using Ammonia-water as refrigerant absorbent pair [8].…”

Solar refrigeration may have applications in both developed and developing countries. Applications in developing countries such as airconditioning, vaccine storage or large scale food preservation have been the subject of scientific research. Ammonia-water based system has good COP but generally vapor absorption refrigeration system requires high generator temperature and high circulating ratio aided by a powerful pump. Our objective was to trivialize the role of circulating ratio and simultaneously achieve higher COP. A prototype model was designed, fabricated in laboratory using scrap material and tested; performance of the unit has been analyzed. A parabolic solar trough was used as a source of heat. Various components were modeled in computer and analyzed using ANSYS. The performances and effectiveness of the unit was studied by determining refrigeration effect (RE) and coefficient of performance (COP).
