Effect of fabric air distribution system in penetration air supply mode on indoor comfort

Taking one room as an object of study, employs the three-dimensional K-ε turbulent model to simulate and analyse the effect under the three upper side wall air-supply and lower side wall return air distributions with the fabric air distribution system in penetration mode (FADSP): FADSP mounted below the ceiling beside the heated wall with the floor-level exhaust opening on the same wall (case 1), FADSP mounted below the ceiling beside the heated wall with the floor-level exhaust opening on the opposite unheated wall (case 2), and FADSP mounted below the ceiling beside the unheated wall with the floor-level exhaust opening on the opposite heated wall (case 3). The results show that the influence of the layout of FADSP on indoor air velocity is less, and the air distributions of inlet opening and exhaust opening on the opposite walls can maintain indoor air with smaller temperature difference and with good comfort, and the air distribution of case 3 has the greater cooling capacity in the same air supply volume.
