The Study of Parameters Effect of Solidification Tubular Ice
ประเภทบทความ : บทความวิชาการ
หมวดหมู่ : วิทยาศาสตร์
This study was aimed to investigate experimental study of the parameters affecting the amount of tube ice compared with theoretical result. Significant studied parameters were inlet water temperature, average ambient air temperature, average ambient refrigerative machinery room temperature and average temperature of surface freezing. The result showed thickness tendency was increasingly according to time. At the beginning of the process thickness increased quite fast and decelerated at the end of the production process, however thickness value acquired from parameters were not identical as average ambient air temperature, average ambient refrigerative machinery room temperature and average temperature of surface freezing slightly affected thickness comparing to the results of the study shown by the ratios between parameter. Inlet water temperature affected to thickness of tube ice as the ratio of inlet water temperature to thickness was 0.41 degrees celsius per milimeter. The ratio of average temperature of surface freezing to thickness was 0.2 degrees celsius per milimeter. The ratio of average ambient refrigerative machinery room temperature to thickness was 0.16 degrees celsius per milimeter, and the ratio of average ambient air temperature to thickness was 0.15 degrees celsius per milimeter. Thus, inlet water temperature affected to thickness of tube ice according to theoretically results with 8 percent error value between ice thickness and production time.
