What should the proper reset strategy be in your opinion?
its a pain but all fans should be reset manually. However, I have seen fans on a BMS have delay starts staggered, so all fans don't come on at once.
if your pipe continues to have leaks than you may have water issues or overall coating issues. But this looks like a isolated hole. Someone hit it with a shovel or bad back fill exposed the raw pipe....and you got corrosion.
5 ton split, will run until it makes temp or cuts out on low pressure. I will assume the fan runs during occupancy? while compressor is off, OA is coming in. If you have a high humid day your in for a fun day. Reheats will be popping on and off. Because you need to have them cut in on a supply...
I would not use a standard 5 ton split with electric heat to control humidity. the electric heat in a split is not designed to be a reheat unless you rewire it to do so. but now your inventing.
need to figure what your sensible cooling load and latent cooling load will be. And size the unit...
all you need to do is keep the room from getting to hot above design of what the condensors are rated for. So I wouldn't worry about bringing the temp down to much. if you kept the room at 80* you will be fine. So the worst case scenario is all machines running when its 95* outside. if your...
If this is a Police station I would ask the contracting officer overseeing the work for some guidance. I completed a GSA job with an evidence storage room and they had particular requirements we had to meet with exhaust, temp and security requirements. Depending on the room they may ask for 24/7...
All the smoke dampers I used were in rooms using FM200 systems. Smoke dampers need to be hooked up to a smoke head or a relay from the fire panel.
fire dampers are rated, smoke dampers alone may not be fire rated for fire walls unless specified and have low or no leakage. Fire and Smoke...
the rubber used in this seal is well within the temperature ranges. If you have glycol in the water that could mess with Fluorocarbon type of o-ring. Do you have glycol? Also if they ran the seal dry that will could damage the seal. (It don't take much time minute or less) or the seal came...
Spec sheet that's all it says. Their other seals will give a min/max.. I think you need to call Crane
