A Research on Constant Temperate Experimental Box Control System Based on Semiconductor Refrigeration Principle

In order to apply the semiconductor refrigeration principle to control constant temperate experimental box,this paper de-signed a high-accuracy temperate control scheme. By modeling the semiconductor refrigerating process,it quantitatively described thesemiconductor refrigerating technology in refrigerating working process. It monitored and studied the temperate change in constant temper-ate experimental box,designed a high-accuracy control algorithm. The simulation test indicated that the average temperate fluctuationrange of 12 temperature observations in constant temperate experimental box is 1%,the punctual temperate is 4%.
