How Does Central AC Affect Fragrance Distribution Across a Multi-Room Diagnostic Centre?

It becomes the plan. On a centrally conditioned floor you are not putting fragrance into a room, you are putting it into a loop, and the loop decides where it goes. Here is the arithmetic that makes the point better than any description. Take a 2,600 sq ft diagnostic floor at a 3.2m ceiling. The whole floor holds 2,600 × 3.2 × 0.0929, about 773 cubic metres of air. The part you actually intended to scent - entrance, reception, waiting - is perhaps 1,050 sq ft, which is 1,050 × 3.2 × 0.0929, about 312 cubic metres. If the system has one air handling unit with a common return, it draws air from across the floor, mixes it and pushes it back out through every supply diffuser. Whatever you introduce in reception is therefore being diluted into roughly two and a half times the volume you sized against, and the portion that is not in your public zone is being delivered somewhere else - including, on many diagnostic floors, into rooms that are on your exclusion list. Two consequences follow, and they pull in opposite directions. The first is that the room can read as weaker than the specification suggested, and the instinct is to turn it up. That instinct is exactly wrong here, because turning it up increases what reaches the excluded rooms in the same proportion as it increases what reaches your waiting area. The second is that you cannot fix this with placement. Placement matters enormously - stay out of the direct supply blast, sit in the slower air travelling toward a return, keep the unit off the counter and about a metre or more up - but placement decides where the output enters the loop, and on a shared return the loop then does what it does. So the sequence is: get the mechanical drawing, find the branch serving reception, and ask your facilities engineer one question - does the return that serves reception also serve any room on the exclusion list. If the answer is no, you have a clean plan and a duct connection is genuinely attractive; an SOSA Angaan at ₹25,999 exists for exactly that situation. If the answer is yes, your realistic options are a much lower level, shorter run windows, and scheduling the source off through the hours when the excluded rooms are busiest - which is what a SOSA Vaayu at ₹11,999 gives you with its 1h/4h/8h/24h windows and adjustable intensity. And sometimes the honest conclusion is the third one: that the zero list cannot be enforced by placement on this floor, and you run nothing until the mechanical picture changes. I would rather write that sentence than sell around it. Fragrance here is an ambience decision like lighting, seating or signage, it works alongside your ventilation and cleaning rather than instead of them, SOSA products are not medical devices, we make no claim that scenting affects how a centre performs commercially, and the clinician's judgement overrides any scenting plan, including mine.
