Three published facts guarantee variation. The bed runs 1 to 2 C above the air around it. Air leaves the handling unit at 14 C to deliver 17 C at the bed, so it warms along its path. Air speed at the bed is limited to 15 cm per second, so the far end gets whatever is left.
Add a door that opens on to a warm corridor, tiers at different heights, and beds of different depth, and one room easily holds two climates.
