[Equest-users] Multistack (DHRC) Dedicated Heat Recovery Chiller

[Daniel Knapp]

I have attached a list of the eQuest reports.   You want look at the LS-B report in the .SIM file.  This gives all of the space peak load components broken down by walls, windows, etc.

However, the gas usage is about 2X what they have been using according to utility information.  The only usages for gas that I have is water heating and space heating.  The water heating contributes very little to the total.  Where in the reports can I see what contribution each element of my envelope is having to the total?  I am assuming that I may have a wall, roof, or window definition incorrect but I do not see anything obvious on the inputs.

You will need to make sure the HW loop is set to operate at or below the Design-Cond-T setting.  Normally there is a back up chiller that operates when there is not a simultaneous heating and cooling load so you will need to create a control scheme as well.  Some sample inputs are below
