Why Is Fragrance Strong in One Appliance Zone but Weak in Another?

Because something on the floor is moving the air in a way the plan did not account for, and the fragrance is going with it. That is the whole diagnosis, and it is useful precisely because it rules out the two things owners reach for first: the machine is not faulty, and the setting is not wrong. A gradient - strong here, weak there, tank emptying on schedule - is a distribution fact, and distribution facts have causes you can walk to. There are five, and they are checked in order. The supply. The AC pushes conditioned air into the room through supply grilles and the fragrance rides that stream; the zone the supply blows towards is strong and the zone it blows away from is weak. If the source is on the wrong wall the supply is carrying the register into a corner rather than across the displays. The return. Return grilles pull air out of the room and take the fragrance with it, so the zone around a return is thin however close the machine is, and a machine near a return is feeding the drain. Where the machine goes on a central-AC floor gives the tissue test that tells supply from return in ten minutes. The door. A busy street or mall door exchanges the threshold air many times an hour; the first few metres inside it will be weak whatever you do, and constantly opening glass doors explains why the answer is to accept it. The partitions. Display kitchens and partition walls block fragrance at the height they stand, so a source at counter height makes the nearest box strong and everything past the first panel weak; do partition walls change fragrance distribution is the fix, which is height. And the cause that belongs to this vertical alone: running demo appliances. An appliance floor is the only kind of showroom where the merchandise itself moves the air. A display air-conditioner on demo blows a stream across its zone and pulls at the air behind it; a running chimney or range hood pulls the air in front of it up and out; an air purifier on a plinth draws the air of its corner through a filter and hands it back stripped; an open built-in fridge spills cold air along the floor. Each one makes a weak zone of its own, and each one is correct to. The AC experience centre and the chimney and hob showroom take these one at a time; the rule across all of them is the same - place the source where the demo units are not blowing or pulling, and accept that the zone in front of a running unit smells of nothing, because that is the demonstration working. Now the thing not to do. Turning the machine up in response to a gradient strengthens the strong zone, feeds the return more, gives the door more to lose, and changes nothing about the weak zone, because the cause is still there. The advisor in the strong zone, who breathes it nine hours a day, is the first to notice. Move the source, do not turn it up. Higher, onto the supply wall, away from the return, inward from the door, above the partitions, out of the demo units' path; then set the level from the zone that was weak, with the team at five in the afternoon, and lock it with the key-lock on the SOSA Vaayu. It is almost never a second machine - one connected volume of air takes one, and a second source in the same air makes a second gradient. Machine and price: the Vaayu you probably already own at ₹11,999, re-mounted; one SOSA Angaan at ₹25,999 past about 3,000 sq ft on one plant, on a duct that serves the sales floor alone only if whoever maintains the plant confirms it - 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 stay unscented. Ask for a showroom scenting plan and shade the strong and weak zones on the plan you send.
