Empirical Analysis on the Correlation Between Mono-crystalline Si Photovoltaic Module Temperature and Irradiance and Ambient Temperature in Seoul Area

Abstract

This study presents a method for calculating carbon-dioxide emissions of diesel trucks during haulage operations by considering road gradient, load capacity and emission standards. An underground limestone mine in Korea was selected as a study area to apply the method. In the study area, variations of emission factors were observed along haulage routes between a crusher and two loading points. The method could simulate the changes of emission factors reasonably with regard to road gradient and load capacity. Along the same haulage route, carbon-dioxide emission decreased by 4-6% with the change of current trucks to newer ones with improved emission standards. The suggested method can be used for the analysis with other vehicle types and greenhouse gases. Therefore, this method can be used for general estimation of greenhouse gas emissions.
