Figure 3

Layouts of the different geometries for which the simulations were performed along with the velocity magnitude isocontours of 0.6 m/s at ACH of 5 for rooms 1-5 and 0.5 m/s at ACH of 10 for room 6. (a) Room 1:  m room with a centrally located 4-way cassette air conditioning unit. (b) Room 2:  m room with a 4-way cassette air conditioning unit that is shifted 1.9 m from the center of the ceiling along the longer horizontal dimension and is central along the shorter horizontal dimension. (c) Room 3:  m room with a wall-mounted 1-way cassette air conditioning unit. (d) Room 4:  m room with a 4-way cassette air conditioning unit that is shifted 2.5 m from the center of the ceiling along one dimension. (e) Room 5:  m room with a centrally located 4-way cassette air conditioning unit and an open window. (f) Room 6:  m room with a wall-mounted 1-way cassette air conditioning unit.
