Additional cooling blower

[Always-interested]

I have some questions regarding adding a "caged blower" from a common house furnace to give additional ventilation for a tanning bed business. When all 25 of the 240v. beds are running, the temp inside the appox. 120'X90' long - 20' tall brick building soars. All beds sit in a common area with 7' tall partitions seperating each. There is a suspended cieling over this entire tanning bed area with a couple office rooms and bathroom framed in the back. They currently have a "pumped up or enhanced" cooling system that will not keep up with the heat. Even during 10 degree winter weather, doors wide open... The fix they they have been using with little success is to open the back door and place a large 5' portable fan in the doorway pointing out... Pretty useless considering it sits at floor level in a small contained room in the back. This room is a storage room with an additional door leading into it from the front tanning bed area. This room along with another small room is seperated from the main area by a floor to cieling wall. Utilities are also in this general area. After watching the employees walk back and forth every 20 min to spin the giant fan around in a futile attempt to pull or push some air into the main room, I suggested to the owner that some sort of blower configured to pull the air out of this main area from cieling height would be much more effective. Owners face: :o He liked the idea and now wants help implimenting. I came up with the idea to use a furnace blower to pull air from this common area and vent it out the back - there is an area just over the rear door that would accomodate a modified duct. Blower could be wall mounted on the inside wall that seperates the rear room from the front. Pulling air from main area then duct 10' over to the top of door, blowing directly out at a 7' height. Only to be used during the cool season. (Rear door or front and rear doors would obviously have to remain open for return air.) Dont know what they would do during hot season but, probably not alot of people using tanning parlors that time of year :? - Are there any concerns you would have with this idea? could this setup somehow disrupt the main cooling system any worse than the 5" fan in the door trick? After thinking a little more I realized that this design might violate some unknown fire codes or such.... (If so, I would'nt touch it...) Hence, my questions to the pro's - Thank you for any input on this!

Without seeing the building and certain tanning room it would be hard to be exact. However you have one room with partiioned slots in that one room full of heat producing tanning beds. This building should properly be heated and cooled by two separate envronmental control systems. [two heating and cooling systems]. Chances are your office and other areas can be ran by your normal heating system.

Then creat an air conditioning system with fresh intake air for that tanning area only. Chances are the heat of the tanning beds will work to maintain warmth in winter using original heating system.

In the summer the tanning room should have duct shut off from existing heating and cooling system and a fresh air cooling system should be installed with fresh air intake through the cooling system and a gravity controlled exhaust louvers at the far end.

I don't have the actual tanning room dimensions yet sounds like a central a/c unit could be installed outdoors with an air handler installed inside with fresh are intake from outside entering that air handler running the fresh air across the A coil of the cooling unit. This draws in fresh conditioned air into that room. When air enters that room then air must leave that room. This is where the louvered vent at far end of the room comes in allowing the super heated moist air to leave the room allowing the conditioned air to enter the room.

A second method depending on layout and size would be install a couple of larger window air conditioners one at far end of room and one at middle of room both blowing to opposite far end of room where the gravity exhaust louver box is installed on that far outside of the room. Set the two window air conditioners to draw fresh air in which will push moist hot air out the vent on the opposite end of that room. If more exhaust is required then you can install a box wall vent fan with that gravity louver wall mount.

If you wish to do this without a/c then you can try installing a gravity vent louver allowing untreated outside air into the room at one end and a box fan with louvers on the opposite end sucking fresh air into the room then pushed hot moist air out through the wall box fan and louver set.

If you have the bucks to spend then sounds like a desert air heat pump system would be the best equipment that conditions the room and controlls the moisture in that room. A desert air heat pump system is advised and most normally used for an indoor pool.

Hope this gives you some ideas.

Good Luck
