Increasing energy efficiency is one of the most important points in our era. Becoming a matter of primary importance in air conditioning, industrial, commercial and process cooling applications, energy efficiency affects designs of the systems included dry coolers and water chillers. Besides, legislations and restrictions on energy efficiency also urge manufacturers to develop high performance, energy efficient, environment friendly, economic and long life products. In these purposes, the tendency towards alternative energy efficient systems, which use natural resources, is increasing. Free cooling is one of the natural resourced methods for energy efficiency. This paper is intended to provide information on free cooling efficiency with a theoretically examination of A, C and E energy class dry coolers combined with the chillers in tandem work in air conditioning application.
