Experimental Analysis of the Filter Element Influence in A/C System

The study objective is to evaluate the thermal comfort and vehicle safety emphasizing on air-conditioning system. Several aspects of automobiles thermal comfort are associated with security issues as the windows defogging and defrosting, and air quality inside the vehicle. For the automotive industry, constant air flow in the vehicle is the reason of continuous research on the improvement of the stream and quality of the air that reaches the occupants. This work presents flow bench and vehicle experimental tests results ass an evaluation of the possibilities of the filter element improvement, for the flow, air filtering and temperature adjustment optimization inside the vehicle. Comfort and safety evaluations were made by the air stream inside the vehicle and experimental tests in a climatic chamber. All the tests were made in the same vehicle. Local head losses were evaluated at the flow bench and the vehicle conditioning at the climatic chamber. The pressure inside the vehicle was analyzed during the flow variation, to ensure a comfortable condition for vehicle occupants.
