The System Design for Improving Semiconductor Refrigeration Performance

According to the working characteristic curve of semiconductor refrigeration chips, the maximum refrigeration capacity and the working current corresponding to the maximum refrigeration efficiency are not consistent. At present, semiconductor refrigeration chips work with a constant current, so it is impossible to keep them in the optimal working state. Because the current corresponding to the maximum refrigeration capacity and the maximum refrigeration efficiency is quite different, in order to improve the performance of semiconductor refrigeration, this paper designs a wide range of adjustable fuzzy control system, which automatically adjusts the current of refrigeration chip according to the temperature of the cold and hot end of the semiconductor refrigeration chip, so that it is always in the best working state.
