Résumé

Transport air conditioning (AC) systems are the very important energy to provide comfort for passenger compartment in metro car or railway car. The determination of cooling load and understanding of their variations are critical for the efficient design of the transport air conditioning system. In this paper, the variation of cooling load in a compartment of metro car or railway car is numerically investigated. Ambient condition, inside condition, car speed, fresh air volume, solar time and number of passengers are taken into consideration as key factors for the numerical simulation and analysis. The investigation is first performed on a compartment without air conditioning unit. Then the entire system which includes air conditioning unit and the compartment are studied. A description and validation of component and system model of air conditioning unit is also given so that the numerical discussion and analysis is more trustable and more valuable.
