[Equest-users] 4-Pipe Fan Coil vs. VAV

[John Aulbach]

Edward:

Are you controlling the cooling coil so it is on WARMEST for COOL-CONTROL ?? You 
need make sure the cooling coil doesn't stay at a constant temperature. Excess 
reheating will kill you.

Subject: [Equest-users] 4-Pipe Fan Coil vs. VAV

I am running a simulation to compare various systems. When I run the 4-pipe fan 
coil and I look at SS-D I get a building load for heating and cooling with what 
it should be but when I use the same building and change the system to Standard 
VAV with HW and CW the building cooling load is 20% higher and the building 
heating load is 65% higher. Does anyone have any suggestions as why this would 
be happening?
