IMPLEMENTATION OF IMPROVEMENTS IN THE CONDENSER OF THE AUTOMOTIVE CONDITIONING SYSTEM AIMING FOR GREATER THERMAL COMFORT

Abstract

The automotive air conditioning systems always used the concept of thermodynamic steam compression cycle. Even after a lot of research, some issues still remain unresolved, such as proper control of the inside temperature of the vehicle in warmer regions, such as in northern Brazil. Focusing on this issue, this article has proposed a new method to improve the control of internal temperature. The proposed method used the same concept of forced ventilation to improve heat exchange in the condenser, using an electro air blower and water from a reservoir. The proposed system was based on the theory of forced convection heat exchange. The results of the data presented showed that the survey was validated due to the drop of temperature of 3 degrees compared with the current system. In addition, the system pressure originally from 230 psi decreased to 150 psi.
