Low temperature plays a very important role in postharvest storage. In this study a transient three-dimensional computational fluid dynamics (CFD) model was applied to investigate the temperature distribution in two cold stores, whose humidity were supplied by nanomist and ultrasonic humidifiers. In order to validate with predicted data, the actual temperature and air velocities were measured inside the containers. The model was successfully validated by means of air velocity with error of 0.09 m s-1 and temperature with mean errors of 0.66 K for nanomist and 0.95 K for ultrasonic, respectively. The findings of this research can help to prove the capability of using CFD to predict the temperature distribution of refrigerated rooms.
