Analysis of Mutual Thermal Effects in Radiator and Condenser Cooling 971774

These days the alignment of radiator and condenser in the vehicle front is the major trend. Due to this alignment, the radiator characteristics are one-sidedly affected by condenser radiating heat, which will cause deterioration in the engine cooling performance at high engine speed and high heat load vehicle operation when air conditioning (A/C) capacity becomes excess.Studies were made on the effects that condenser operation have on radiator characteristics. Results showed that controlling the condenser operation characteristics will provide improved A/C and engine cooling performance in the vehicle system.This paper will discuss the details of the above-mentioned analyses with focus on the vehicle characteristics of front engine, front drive (FF) vehicles and the results of vehicle proving tests.
