Numerical Analysis of Performance a Trombe Wall in Dry Climate

In this paper, operation of Trombe wall system and how air flows inside the room in a steady and unsteady state has been studied. The goal was to examine the optimal size of the system (steady state) for save more energy and its impact on the interior of the room when system start till the system reaches a steady state (unsteady state) and also calculate the amount of hours that the stored energy in the absence of solar radiation transmitted into the inside of room. Tostartthe system, assumethat allvelocitiesarezero and the interiorroomislocatedin theminimumtemperatureinwinter and systemstartedtoworkwithsolar radiationandthermal energyfromthe sun.
