    Ventilation in unoccupied garage - ASHRAE 62.1

    Drazen: The fire truck garage is considered a "storage garage" as there will be no repair done in the garage. The garage is heated as it can be used for training of the volunteer fire fighters and there are exposed water lines; we also need to protect the equipment located in the fire trucks...

    Ventilation in unoccupied garage - ASHRAE 62.1

    Correction: They are not interested in paying for equipment that is NOT absolutely required. The absence of the dedicated tailpipe system has been approved by the authority as well as the head fire chief for the area.

    Great discussion. Definitely giving us loads to think about!

    Ventilation in unoccupied garage - ASHRAE 62.1

    DrRTU: Thank you for the reference. Yes, the fire department is aware; they specifically requested not to have exhaust capture. This is a volunteer department and they are not interested in paying for equipment that is absolutely required. Drazen: Thanks for your recommendation. We were...

    Ventilation in unoccupied garage - ASHRAE 62.1

    On what is 0.05 CFM/ft2 based? HRV is what we are considering for continuous ventilation. A dedicated tailpipe collection system is not required in this case; we have cleared it with the appropriate authorities.

    Well pump & pressure tank for fire hall

    BigInch: short of putting in two pumps, do you have any other suggestions?

    Wow thanks for the link! That really makes it easy to understand. I think this is our solution.

    Well pump & pressure tank for fire hall

    Sorry to be a pain, I haven't used a constant pressure valve before. It does seem adequate for what we need. But the pump has no VFD, how will it work like a 5GPM pump? If the pump is only pushing 5 GPM, it will not even get the water out of the well.

    Well pump & pressure tank for fire hall

    Good point, we have specified a double check backflow preventer, which suits local regulations here.

    Ventilation in unoccupied garage - ASHRAE 62.1

    I am working on the HVAC design of a new fire hall building. The fire department is 100% volunteer based and the building will be unoccupied most of the time. The truck bay and bunker room is roughly 6000 square feet; there are 5 truck bays. We have exhaust fans and fresh air intake louvers...

    Well pump & pressure tank for fire hall

    - Didn't give up, just got sidetracked! [glasses] Thanks for all comments up to date! Very informative. - Yes, the well can provide 200 gpm. Well is 300' deep. - We are looking into the deep well pump option. Do I understand correctly that a submersible pump could be installed in the well in...

    Well pump & pressure tank for fire hall

    Happy to see so many suggestions. Keep them coming! Here are my thoughts: - The storage tank would not actually be "open to atmosphere"; just a standard water storage tank, same as a cistern. It would be fairly small, say 80 gals. This would eliminate our worry for freshness of water for...

    Well pump & pressure tank for fire hall

    What about having the 200GPM 20HP pump serving a water storage tank (open to atmosphere)? The storage tank could have a small pump to maintain pressure in the building domestic water piping. When the tank is down to say 25%, the well pump fills it up. When the Fire Department needs to fill...

    Thanks for the feedback on the VFD. Two pumps would be ideal. Not sure we would be able to fit two in the well, casing is 8".

    Well pump & pressure tank for fire hall

    I am helping to design the plumbing systems for a new municipal building in Eastern Canada (New Brunswick) that will house a volunteer Fire Department and the municipal offices. The Fire Department requires roughly 200GPM of water flow from the well in order to fill their trucks. The building...
