How Do I Scent a Long, Narrow Modular Kitchen Showroom?

With one machine at the upstream end of the run, and with rather more confidence than most owners of deep shop units arrive with. The instinct is that length is the enemy - that a hundred feet is simply too far for one source and the answer must be two or three spread along the way. It is the wrong model. A narrow plan is a conduit. Air entering it has nowhere to disperse sideways, so instead of spreading in four directions and thinning as it goes, it travels the length of the unit in one direction, which is exactly the behaviour you want. A square floor of the same area is genuinely harder, because the same output has four ways to wander. So the first thing to do is stop apologising for the shape. The second is to find the upstream end, and this is where people are usually surprised: it is frequently the back of the unit rather than the front. In a deep shop the plant is often at the rear, the supplies run forward from it, and the return sits near the front or in the corridor. Do the tissue walk - light tissue under each warm ceiling grille, lifting away is a supply and pulled flat is a return - and mark them on the plan. Then place two or three metres downstream of the first supply on the run, roughly a metre off the floor. What you must not do is put the machine halfway along, which feels even-handed and is the worst position on the plan. Half the unit is then upstream of the source. The machine spends part of its output riding the air path and part of it pushing against it, and the far end - which is usually where your consultation table is, because that is where the quiet is - receives the least. Now the arithmetic, because it settles the second-machine question honestly. A 20ft × 100ft unit is 2,000 sq ft, about 186m², which at an ordinary 3m ceiling is roughly 558m³. One SOSA Vaayu at ₹11,999 is rated to 1000m³, so the machine is running at a little over half its range and will do the whole length at a low setting. Two machines there would give you two sources in one shared volume and a join in the middle. A second machine is justified only by a genuinely separate volume of air - a closed consultation room at the back, another floor, its own conditioning zone - and never by a second point along the same open run. Under about 750 sq ft, which a 15ft × 45ft unit is, the honest buy is a SOSA Sukoon at ₹1,899 and a Vaayu would be the wrong purchase. Whether your supplies actually reach the far end, how far the diffusers throw and whether the run was balanced after the fit-out are your HVAC contractor's questions. And none of this is a way to cover a smell. Ask for a retail scenting plan and send the run with its grilles marked.
