In order to improve product quality, decrease capital cost and increase final cost of dried products, several studies have been conducted. Using heat pump dryers the latent and sensible heat of exhaust air from drying chamber are saved , therefore, the energy efficiency of systems have been increased. The results of performance and economic analysis of an air source heat pump assisted-drying system are presented and the relations between these are showed in a nomogram which designed to allow the approximate graphical computation of a function and topredict the system performance graphically for wide ranges of evaporator and condenser temperatures and different and make a connection betweenthem and economic analysis.
