TEMPERATURE CONTROL SYSTEM FOR REACTION VESSEL

摘要

PURPOSE:To deal with temperature variation of respective reaction vessels by controlling a set of coolers by operating temperature difference data corresponding the plural reaction vessels based on temperature difference operation expression data corresponding to the combinations of the plus and minus signs of the difference data between respective reaction vessel temperatures and a set temperature and of the temperature transition data of the respective reaction vessels. CONSTITUTION:The temperatures of the respective reaction vessels 1, 2 are detected periodically with a prescribed time interval, and difference data and temperature transition data are calculated, and based on the combination of the plus and minus signs of thus obtained data, corresponding temperature difference operation expression data 60 is extracted from a temperature difference operation expression table 13 in order to calculate temperature data for the plural reaction vessels; a temperature control part 12 to control the cooler 5 through above processes is provided. Thus, by detecting the temperatures of the respective reaction vessels and by calculating the plus and the minus signs, the corresponding operation expression data 60 can be extracted, and additionally a manipulated variable with the temperature of each reaction vessel taken into account can be obtained through a simple formula.
