Special aspects of the internal combustion engines air-cooler calculation with focus on the air moisture condensation are presented. The useful method for the prediction of air moisture condensation during the process of air cooling has been suggested. The results of coupled simulations of cooling system and heat exchangers, which compose the cooling system, for various types of engines and for the set of charge air pressure level are shown. The different influence of air moisture condensation on the cooling air parameters depending on the charge pressure level is revealed in the article.

Key words: air moisture, air-cooler, condensation, heat of vaporization, explicit heat.
