스마트 교행 제어기 모형 개발 = A Smart Alternate-Crossing Control Model and Its Prototype Implementation

다국어 초록 (Multilingual Abstract)

In this paper, we investigate how common factors, shared by the variables related to the heat pump dryer, depend on the power consumption of the dryer. As the power consumption of a hear pump dryer, in general, attributes to many variables in a complicated fashion, it is not trivial to control the dependency of the power consumption on the variables. To overcome the difficulty in controling the power consumption, we utilize exploratory factor analysis under the assumption that the observed variance is attributable to a relatively small number of common factors. From the analysis we identified two common factors that account for about 74% of the total variance. It turned out that the variables loading highly on the first common factor are refrigerants of compressor, condenser, expansion, and evaporator; whereas the variables on the second common factor are water temperature of the condenser. We also found that the power consumption depends linearly on the first common factor. Thess results can be applied to a more elaborate control of the power consumption in the heat pump dryer.
