Performance analysis of a passive cooling system using underground channel (Naghb)

摘要: The present study, aims at introducing and studying the effect of an old specific type house cooling system in Bam city. Primary is similar to Baud-Geers (wind tower) but mentioned system, there additional channel connected Baud-Geer which called Naghb. Naghb fact underneath that uses ground humidity cool air. input wind passes through evaporation makes it cooler Therefore, enhances. Unfortunately, all Naghbs destroyed earthquake happened on December 26, 2003 only ruins them are left, hence order study performance a one-dimensional model presented conservation equations energy, mass momentum have been solved simultaneously. In evaluate model, simple experimental setup made basis real dimensions results reveal ability air during hot dry months Bam.
