Entering cooling/heating capacities

Hi,

We have Air Handler data from a building that I need to enter into the
model. However, I am still new to this and have two questions:

First, when I go to enter this information, we are not able to select
Chilled Water and for capacities I find that several cells says n/a and do
not allow me to enter in a value. I am thinking that there must be a higher
level item that needs to be altered, but I do not know what it is.

For example, in this Sys1 (VAVS), we want to select Chilled Water from the
pull down, but it doesn't let us:

In this screen, I am able to enter in a cooling capacity, but the cooling
capacity cell in the E1 Core Zn which is shown as a subsystem of this one,
has the n/a and does not allow entry. Same thing for heating.

Second, when we enter in heating capacities, it seems that they have to be
entered in as a negative number. Is that just the format of eQuest so a
heating coil with 500 MBH capacity gets entered as -500 MBH?

Thanks,

Sol

Sol,
I think the Cool Source shows as N/A because the only option for the VAVS system type is chilled water. (You would have to pick PVAVS if you wanted DX cooling.)
Yes, most heating capacity inputs in eQUEST need to be entered as negative values.
For more specific questions, I suggest attaching your model .inp and .pd2 files in future posts to equest-users.
Regards,
Bill
