HAP: Air Tempering Unit with vent reclaim (direct exhaust)

HAP: Air Tempering Unit with vent reclaim (direct exhaust)

(OP)
In HAP 4.8:
01- When we choose Air Tempering Unit and check on vent. reclaim there is no affect take place on cooling load. How to correct it?
02- How to adjust direct exhaust in the Air Tempering unit with vent. reclaim, because there is no direct exhaust cell in the system.

RE: HAP: Air Tempering Unit with vent reclaim (direct exhaust)

You should speak to the manufacturer.

RE: HAP: Air Tempering Unit with vent reclaim (direct exhaust)

your file link does not work.

what do you need exact direct exhaust for? hap does not calculate ducting.

RE: HAP: Air Tempering Unit with vent reclaim (direct exhaust)

Need to clarify what you are referring to when you say "cooling load" and / or fix your file link.

Have you tried contacting HAP technical support?

Also try Carrier's HAP e-Help pages, they've posted many white pages and guides on how to use their software.

RE: HAP: Air Tempering Unit with vent reclaim (direct exhaust)

Check to see if your return air and outside air temperature are similar. If they are then there will be no benefit in cooling mode. The exhaust is assumed to match either the ventilation load or the sum of the zone direct exhaust volumes.

RE: HAP: Air Tempering Unit with vent reclaim (direct exhaust)



Use HAP tech support. They are excellent and quick.

Best to you,
