[Hap-users] FCU Terminal Unit Coil Leaving Temperature

[Joyce Constable via Hap-users]

Hi All,

The following is in reference to HAP 5.0.

There will be multiple Fan Coil Units in the HVAC system, with a common Return Air/Ventilation Air System.
In the FCU unit section, Zone Components, Common Data, I check the Cooling Coil Design Supply Temp at 55°F.
When I run the program, the Coil Leaving  Temps range from 58.3°F db/57.2°F wb to 64.5°F db/63.5°F wb; and Coil Entering Temps 78.4°F db/66.7wb to 79.2°F db/69.3°Fwb
Can Anyone comment on why Hap doesn't calculate the Loads using the 55°F Design Supply Temp?

Any information is greatly appreciated.
Thank you.
