چکیده
due to the increasing development in various branches of the automotive industry, the need for a comfort climate in the cabin is more sensible. however, to achieve climate comfort, hvac system consumes a considerable amount of engine power. hence, improving hvac system performance leads to more energy saving of the vehicle which is a critical factor for nowadays automotive. besides, one crucial task of hvac system is defrosting/defogging of windshield which is considered as a mandatory requirement in most countries. in the current study, the defrosting/defogging performance of hvac system in the main product of national vehicle platform is numerically evaluated based on the ece-78-715 legal requirement. for this purpose, after validation and mesh independency study, the transient air flow in three-dimensional cabin geometry is simulated by sstk-ω turbulence model via ansys fluent software and the windshield thermal condition is reported during defrosting/defogging. besides, two national hvac standards of aerc-10-01 and aerc-10-02 are also checked. the results demonstrate that hvac system of the main product of the national vehicle platform can satisfactorily fulfill ece-78-715, aerc-10-01 and aerc-10-02.
