Determination of exhaust heat ventilation rate in rubber vulcanization workshop based on effective thermal coefficient of work area

 With an actual project, analyses the relationship between the effective thermal coefficient of a single vulcanizing machine and the exhaust heat ventilation rate and the heat dissipation of equipment under ideal air supply conditions. Studies the effects of the exhaust outlet height and the enclosure height on the effective thermal coefficient. On the basis of determining the ventilation rate of single vulcanizing machine, introduces the correction coefficient to obtain the minimum total exhaust heat ventilation rate required by an actual production line of vulcanizing machine with centralized air supply from both ends. The results show that when the number of vulcanizing machines is 1, 7, 14 and 21, the correction coefficient of the ventilation rate for a single vulcanizing machine is 1.00, 1.36, 1.45 and 1.64, respectively.
