ventilation design for a 25 meter indoor range
ventilation design for a 25 meter indoor range
(OP)
Hi, all
I currently reviewing an indoor range ventilation design.
The consultant had proposed an supply/extraction system with and mixer box and dehumidifer system
I had another consultant which provide me, an supply and extraction system with an run around coil; heat recovery system.
Any comments and also is there a best practice/standard for ventilation in a indoor range.
I stay in a topical country, where ambient temp is 32C

After i designed a two lane gun range to meet all of the good engineering practices, the cost of the lanes was more than the cost of the building. So prepare for sticker shock and lots of VE.
You should filter the exhaust thru hepa filters to be a good neighbor.
You should have a uniform air velocity across the shooter, don't blow air on the back of their neck.
Anthing in a gun range will be hit by a bullet at some point in time. Don't put any critical component in the range.

The both designs had an extraction system at the bullet trap area fit with HEPA filter. I am just wondering how effective is the heat recovery method in of the the design.
Is here other design which i can make reference to ?
Will do a search on the internet too.
thanks

Regarding the run around coil heat recovery system, it may or may not be an effective system for your design. With high air flow rates and large temperature differences from inside to outside, it can be a good investment. Lower airflow rates and increased distance between inlet and exhaust coils could produce a system that will never pay for itself. Ading two coils to your system plus a pump to circulate fluid will increase your energy costs. You have to make sure that the system will recover substantially more energy than it takes to operate and maintain to be able to pay for the intial cost. Another option may be to duct the two airstreams closer together and do some sort of air to air heat exchanger. This way you only have to exchange heat once rather than twice. Hope this helps.
