How Do I Scent a Long, Narrow Home-Appliance Showroom?

From one point, chosen by thirds, on the wall the air moves across. Start with what the shape does to the air, because a corridor floor behaves unlike a square one. The door is at one narrow end and it is a draught - the threshold air swaps with the street all day, which constantly opening glass doors works through - and the far end is the stillest air on the floor, furthest from the door and often nearest the plant room and the returns. Between them the AC supply grilles run down the length, usually along one long wall or the ceiling centre-line, and they push the conditioned air along the corridor rather than across it. Fragrance released into that stream travels the way the stream does. Now the placement. A source at the door end feeds the draught and reaches the far displays last, if at all. A source at the far end charges the dead air behind it and starves the middle. The third-point is the compromise the air itself suggests: mount the machine one third of the length in from the far end, two thirds from the door, high on the long wall the supply grilles blow across. From there the moving air carries the register forward towards the door - losing some to the threshold, which is accepted - and the far third behind the source charges from its own stillness. The far end is where the level is judged, with the team at five in the afternoon, and the door end is allowed to be whatever the door makes it. Then the rule this page exists to hold. A long floor is still one connected volume of air, and one volume takes one machine. The instinct to add a second unit at the door end because the entrance is thin produces two gradients in the same air, meeting somewhere near the middle at a level nobody set, and it still leaves the doorway smelling of the street. A second machine belongs only to a second AC zone: a floor split by a wall or a partition to the ceiling and served by its own supply and return. On one zone, if the far end is thin the source moves further back along the same wall; if the door end is thin the source stays where it is and the door is accepted. Height matters on a corridor floor more than on most, because the display kitchens are usually in a row down one side and each is a partition at counter height - mount above the tallest partition line and the boxes stop breaking the run; do partition walls change fragrance distribution is the full version. The wall mount on the SOSA Vaayu is what makes the third-point available at all; the socket is never there. Machine and price: one Vaayu at ₹11,999 for a connected corridor floor of roughly 1,500-3,000 sq ft, waterless, timer and key-lock; one SOSA Angaan at ₹25,999 for a longer floor past about 3,000 sq ft on a single plant, wall-mounted at the same third-point or on a duct that serves the sales floor alone, confirmed by whoever maintains the plant - SOSA gives no engineering advice. And the frame: fragrance is an interiors decision, like lighting or music. SOSA makes no claim that it changes dwell time, footfall, conversion or sales, no claim about what it does to any appliance or finish, and it is never a substitute for ventilation, cleaning or extraction. The live kitchen and coffee counter, wherever they sit along the length, stay unscented. Ask for a showroom scenting plan and mark the length, the grilles and the door on what you send.
