Design and Analysis of a Direct Evaporative Cooling System for Vehicular Air Conditioning

摘要

This manuscript analyzes the sub-systems of evaporative cooler for automotive air conditioning purpose. The thermodynamic and psychometric were conducted to design all evaporative cooling system components in terms of desiccant selection, compact heat exchanger and evaporative cooler. Also, the effect of the desiccant, heat exchanger and evaporative performances on the mass flow rate and water sprayed required for evaporative cooling system were investigated. The results show the theoretical evaporative cooling design will achieve two main objectives a lower fuel consumption and less environmental pollutants. And it has two drawbacks in terms of increase weight and reduce the coefficient of performance (COP).
