Try Aaon or Addison I believe they make packaged units with this low a CFM. I don't know if they publish the data, but their reps will know. Both make 100% OA units that control both temperature and humidity.
You are correct that desicaant dehumidifiers have higher maintenance requirements than DX units, however they will give you the best humdidity control. To get 33F leaving air temperature you are really talking about a refrigeration unit not a typical DX unit. Is there a reason you want such a...
We have Duct Sox in our office, and I have used them in a number of applications and am very please with them. In our office with have two different types, the liner slot and perforated holes. I don't think they make the liner slot anymore as it has a tendency to clog. I personally have taken...
Is it possible to use a hot gas reheat coil? You can let the compressors run making 55F leaving air, and then reheat the air with the hot gas. Since the hot gas is recovered energy you don't violate the energy code. We use this system quite often in Georgia.
AIA publishes Guidelines for design and construction of health care facilities, or you could try the HVAC design Manual from the Department of Veterans Affairs.
Just as a note. For a VAV system you do not need balancing (volume) dampers upstream of the VAV boxes. Also I would still require the OBD at the diffusers. This allows you to fine tune the system.
You need follow the ASHREA 62 guidelines. It is no longer as simple as 15 cfm/person. You will need to take into account the airflow percentage that is delivered to each space, and what portion of that is OA. Since it is a constant volume system this is an easy calculation. Also, ASHREA 62...
Please read the below email, it is in response to a questions regarding the face velocity for laminar flow diffusers in operating rooms. My understanding is that a laminar flow diffuser does not entrain any room air as it exits the diffuser. Without additional volume how does the air speed up...
