<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Consider a building with an air handler
with a 54F supply temperature, and a 45F entering CHW temperature. If the
fan is draw through, and the fan heat is 4F, then the temperature leaving the
cooling coil must be 50F in order to produce 54F downstream of the fan.
But 50F – 45F = 5F, which is a delta too low for the coil curves to
handle. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt;

building’s performance but every time that the simulation runs an error
message pops up and cancels the simulation. The error message is
“cooling coil leaving temperature must be at least 6F higher than
entering water temperature.” I am not sure where in the program,
equest, where you can manually enter the value for entering and leaving water
temperature across a cooling coil.<o:p></o:p></span></font></p>
