A evaporator of car air conditioner is an aluminum heat exchanger which cools air. There has been greater demand for more comfortable air with little odor. The cause of an adsorbed odor emanated from car air conditioner was studied. We proved that the odor is caused by adsorption and desorption of odor substances from exhaust gas, tobacco smoke and others. We found a close correlation between sensory test data and chemical analysis data of the odor and specified main odor substances with multivariate analysis.
