RE: [EnergyPlus_Support] Re: Asking about ZoneControl:Thermostat





In the DataSet folder there is a Schedule.IDF which list all the ASHRAE 90.1-1989,

 

I do not use them because I need not work with the AXHRAE guidelines.

 

There are many other useful data in that folder.

 

Basically, a schedule is expanded and processed before use during simulation.

 

In the older version, the schedule are arrange for year, calling the months, calling the weeks and days.  There are 12 day types.  This log  format is still valid.

 

The Schedule Compact format combines all these into one.

=================
Schedule:Compact,
Assembly HVAC, !- Name
on/off, !- Schedule Type Limits Name
Through: 12/31, !- Field 1
For: Weekdays SummerDesignDay, !- Field 2
Until: 05:00, 0.0, !- Field 4
Until: 23:00, 1.0, !- Field 6
Until: 24:00, 0.0, !- Field 8
For: Saturday WinterDesignDay, !- Field 9
Until: 06:00, 0.0, !- Field 11
Until: 23:00, 1.0, !- Field 13
Until: 24:00, 0.0, !- Field 15
For: Sunday Holidays AllOtherDays, !- Field 16
Until: 06:00, 0.0, !- Field 18
Until: 23:00, 1.0, !- Field 20
Until: 24:00, 0.0; !- Field 22
------------------------
The above schedule cover one year with no seasonal change.  "Though:" is the period end date.  The schedule start with 1/1 and must cover the whole year period with 12/31.
 
All day types are covered with the "For:" groups.  All the twelve day tpe must be specified.
Weekends (Saturday and Sunday) is not used, and the two days are shown separately.
AllOtherDays includes the Custom1 and custom2.
The "Until:" specify the end time and the value to use. Starting time is 00.01 after  Midnight.
The value should be within the Schedule Type Limit.  The last time must be 24.00.

Dear Dr. Li,

Thank you for the explanation. I have one more question. What is the meaning of seasonal controlled schedule you mention before?
