#### Abstract

Heat exchangers are devices that transfer energy between fluids at different temperatures by heat transfer. These devices can be used widely both in daily life and industrial applications such as steam generators in thermal power plants, distillers in chemical industry, evaporators and condensers in HVAC applications and refrigeration process, heat sinks, automobile radiators and regenerators in gas turbine engines. This chapter discusses the basic design methods for two fluid heat exchangers.

Keywords: log-mean temperature difference (LMTD), effectiveness-number of transfer units (ε NTU), dimensionless mean temperature difference (Ψ P) and (P<sup>1</sup> – P2) effectiveness-modified number of transfer units (ε NTUo), reduced length and reduced period (Λ π)
