Dear Chandan, Brent, Jean,
Thanks for the feedback! I must say, though, that I was hoping to avoid learning EMS for maybe 30 years or so…
Perhaps this is actually a development issue, but I thought about this a bit more and would like to know your thoughts in response:
The normal warning I receive is shown below and is quite understandable.
Occasionally a DX coil “wants” to start to satisfy a cooling load in cool weather due to high internal loads, or (as is my case) it may be a DOAS with hot gas reheat and is trying to dehumidify a humid zone. Both uses are legitimate. Both will result in a lot of warnings.
In the first case, I can live with a slight increase in the zone temperature during those hours. In the second case, the zone humidity will probably drop once the air system operates for a while (my DOAS was trying to dehumidify in the first few hours after startup)
Most commercial HVAC equipment, however, is equipped with a low temperature limit control for the DX cooling that prevents its operation below a fixed temperature. It sure would make an energy modeler’s life more simple if I could just turn the coil OFF with a standard object field instead of EMS! (something like the feature that already exists for the Heat Pump DX heating coil)
** Warning ** Coil:Cooling:DX:SingleSpeed "CLGCOIL1_PROPDOASWVRF0" - Full load outlet air dry-bulb temperature < 2C. This indicates the possibility of coil frost/freeze. Outlet temperature = 1.77 C.
