Re: Ventilation in Hot Area

For examples today the temperature is set at 26C (79F) with 50% humidity. While next week its 30C (86F)
This will set to rise slowly from April onwards with June to September witnessing +40C (104F) to 50C (122F). then slowly it goes down as winter approaches to +20C.

The outside corridor is fully air-conditioned 24/7. While the shop windows are are reflective double glazed glasses with a black tint to it to protect maximum heat coming into the shop. Basically the only heat coming into the shop would be mostly generated from the tanning units.

The tanning units won't be running nonstop at full capacity. Probably daily 10-20 times.
3 of the units each generate 3,000m3/h (1,765cfm) heat
while one generates 2,300 m3/h (1,353cfm)
That's a total of 11,300 m3/h (6650cfm) if all are running at same point.

A 5 ton split duct AC with installation would cost with installation around $2700. I've already added this before the ceiling goes on. Once the ceiling is added then it would be tough to add another unit. Is it recommended to add any extra tons or I'm fine with 9 tons now?
