Abstract

The thermal environment and air quality in a passenger car can affect driver's and passengers' health,
performance and comfort. Due to spatial and temporal variation of state variables and boundary conditions in the vehicle
cab, the heating, ventilating and air-conditioning (HVAC) does not have to be designed to provide a uniform environment,
especially because of individual differences regarding to physiological and psychological response, clothing insulation,
activity, air temperature and air movement preference, etc. Therefore the system should be able to generate preferred local
environmental conditions, even on individual body part level.
Spot, or distributed, cooling is an energy efficient way of delivering comfort to an occupant in the car. The
present paper focuses on the design and experimental analysis of the energy efficient HVAC system with spot or localized
cooling .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. Localized cooling, on the other hand, focuses on keeping the
passenger comfortable by forming a micro climate around the passenger. Spot cooling was achieved by strategically placing
multiple nozzles in the vehicle directed at specific body parts. This paper focuses on the numerical study of the temperature
field and air flow inside a passenger’s cabin with different human load.
The main goal is to investigate the distribution of temperature and air flow with various human loads inside the passenger
compartment in the steady-state conditions.
