Suggestions for doggie daycare warehouse.
Client has 5000 sqft of space with a vaulted ceiling. Almost like a basketball court/warehouse if you will. Engineering can't support a larger unit on the roof. So I am going to throw this out there 2 5T HP w/ a HRV on one unit to bring in fresh air and TRIO 20/2000 to kill bacteria and a dehumidifier on the closed unit while using fabric ductwork on both ends pulling in air from the apex and pushing it out the bottom. Lots of dogs is going to make it humid and EV will help keep smells down and yes we will need some fresh air. Both tied in to the same thermostat. Suggestions? Thoughts? Thank you!

How many dogs, and how many people.

now it's 25 dogs and 2 people later it will be 60 dogs. That's a lot of moisture and smell of piss. Fresh air hrv, bacteria scrubber/advanced filter and dehumidifier definitely needed.
The CFM for the 5 ton air handler is 1750

Do yourself a favor and hire a Engineering Ferm.
The liabilities are just too high for guessing.

We definitely do when anything over 5 ton is going on a roof.

I think what PECMSG meant was hire a mechanical engineer to design the system based on your local codes, not so much as reference to the structural engineer you already hired to calculate the roofing loads.

A 1,000 CFM HRV might be big enough. Depends how leaky the building is.
After a load cal, a single 10 ton package unit on the ground might be enough for the space.
You don't want a RTU/unit on the roof. PITA keeping the coils clean, having to go up there every 30 to 45 days.

I cant speak as to the load but i can speak as to the application. you're gonna need something to catch the hair. other than the filter in the unit. Maybe a Pre filter and final filter set up, with the pre filters changed every month. Having serviced units for both a dog day care and a grooming salon. Those filters get plugged up quick. Every time i changed the filters there was about a wookies worth of hair on each one. I cleaned a coil once for the grooming salon, must have pulled out enough hair to make a new dog. Just my .02
