A semi-empirical model for simulating thermal and energy performance of an automotive air-conditioning (AAC) system in passenger vehicles has been developed. The model consists of two sections, namely empirical evaporator correlations and dynamic load simulation. The correlations used consider sensible and latent heat transfer performance of the evaporator coil. The correlations were obtained f...

Traditional vehicle air conditioning systems condition the entire cabin to a comfortable range of temperature and humidity regardless of the number of passengers in the vehicle. The A/C system is designed to have enough capacity to provide comfort for transient periods when cooling down a soaked car. Similarly for heating, the entire cabin is typically warmed up to achieve comfort. Localized he...

background: xylene is known as one of the most toxic of the nervous system. the purpose of this study is to estimate the concentration of xylene in the cabin of the vehicles production in iran. also the effect of ventilation, cigarette smoking, and air freshener inside the vehicle, fuel type and car decorations on the concentration of the substance being studied.   methods: 152 vehicles pride a...

It is not surprising that air quality in vehicle cabins is usually found to be worse than that typically found in homes or workplaces, especially when so many exhaust pipes are only inches away from adjacent vehicles. Pollutants find their way into the cabin via the ventilation system, also known as the Heating, Ventilation and Air Conditioning (HVAC) system. Independent studies [1–3] have show...

When a vehicle is left parked in the sun for an extended period, gathered heat causes damage to several interiors within cabin and discomfort people animals inside car. In present work, effect of orientation white minibus on temperature distribution cooling load calculation studied experimentally open environment. Two different cases were facing south east. For hours, car had been monitored mea...

Thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. To implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were de...
