Dear all,
There is an error that has come up while simulating a 6 lakh sq. ft. bldg.
"cooling coil leaving temperature must be at least 6F higher than entering
water temp."
The CHW temp is 44 F and I have tried varying the zone supply temperature
from 52 to 60 F. But no luck. The air side system here was PIU or VAV.
However, when I model the same with an FCU at the air side. No error
appears.
Any clues why such strange behavior and how to resolve it?
Thanks in advance
Kushagra
