Bowling Alley Cooling
Bowling Alley Cooling
(OP)
We have been brought in to look at the existing mechanical system in a bowling alley. I'm working the heating/cooling loads for the bowling areas. Each area is 12,300 sq. ft. Minimal to no insulation in each area. The north lanes load is 32 ton, south is 34 tons.
Since all of the people & activity is towards the interior space. (Bowling on left side, concourse in middle, bowling on right side) do I need to figure the full tonnage for each area. There is a separate unit that handles the concourse area.
It doesn't need to be 70* down near the pins but I'm not sure if I figure smaller units, the heat will migrate towards the interior space and the whole bowling area will not be satisfied. Currently, the ductwork only goes about 1/4 way down the lanes towards the pins. Their existing system doesn't keep up in the summertime. They have about 20 tons on each side now.

12300/500 = 24.6 tons 12300/700 = 17.6 tons, so it looks like the existing system is sized about right for the floor area with adequate insulation. One question to ask is whether the cooling was ever adequate, or was it marginal from the get-go. Perhaps, due to the age, it simply need a major tuneup, ii.e., cleaning the ducts, replacing the exchangers, etc. Or, can additional insulation be installed, which might be cheaper than redoing the A/C system.
Do you know whether the concourse is adequately sized, or is it stealing capacity from the bowling alley?

Currently there is a 60 ton air handler. Off the supply plenum, the duct splits into three. Duct is sized for 20 ton to north lanes, 20 ton to concourse, 20 ton to south lanes.
Each of the three branches has a duct furnace 300,000 btu each.

If I go with 2-35 ton units, would I have to distribute the air/duct throughout the lanes or could I get away with dumping most of it where the bowlers sit and 1/3 down the lanes?
