[Equest-users] equest crashing on chilled water loop primaryselection

[RobertGChronic at Eaton.com]

Since this is a campus connection, I only wanted the load of the chilled
water and not necessarily size a chiller plant.  I thought the easiest
way was to "replace" the plant with a meter and have the meter tally up
the loads.  I certainly would welcome any feedback if there are better /
easier ways to model a campus chilled water connection.

 

Thanks!

You only seem to have a chilled water meter attached to this loop - no
primary equipment (chiller) so there is nothing to size to.

I am having an issue with equest crashing.  The error is associated with
the subtype being secondary for the chilled water loop, however, when I
switch it back to primary, I immediately get kicked out of equest.   I
have attached the screenshot of equest and the chilled water loop
appears to be nested.  I am not sure how this exactly happened, I was
attempting to redefine the chilled water loop.  Here is the excerpt from
the bdl file.  Is there any way to edit outside of equest interface so I
can alleviate the crashing??

 

 

     *3099 * "Chilled Water Loop" = CIRCULATION-LOOP

     *3100 *    TYPE             = CHW

     *3101 *    SUBTYPE          = SECONDARY

     *3102 *    LOOP-DESIGN-DT   = 15

     *3103 *    SIZING-OPTION    = PRIMARY

     *3104 *    PIPE-HEAD        = 55

     *3105 *    PRIMARY-LOOP     = "Chilled Water Loop"

     *3106 *    LOOP-OPERATION   = DEMAND

     *3107 *    DESIGN-COOL-T    = 45

     *3108 *    COOL-SETPT-CTRL  = FIXED

     *3109 *    LOOP-PUMP        = "CHW Loop Pump"

     *3110 *    HEAD-SETPT-CTRL  = FIXED

     *3111 *    HEAD-SETPT       = 30

     *3112 *    ..

*ERROR******************************************************************
**********************

*ERROR*****Chilled Water Loop cannot be specified as a PRIMARY-LOOP due
to

            incorrect SUBTYPE; valid PRIMARY-LOOP must have a SUBTYPE of
PRIMARY

 

 

Thanks!
