7/12 Schedules - Defined Using Profiles

General tab on Schedules Dialog.

 

7/12 Schedules reference Profiles, one Profile for each day of the week and for each month of the year (hence 7/12).

 

You can select multiple rows (months) or columns (days) and edit the data by clicking on the Edit selected cells link in the Info Panel. Likewise, you can select individual profiles by clicking on the appropriate cell and clicking Edit selected cells.

Design days

Winter and summer design day simulations are carried out when required for autosizing heating and cooling equipment prior to a Compact HVAC simulation.

Design day definition method

With 7/12 Schedules there are 2 ways to define the schedule output during these winter design day simulations:

 

1. End-use defaults - use the default heating autosizing behaviour defined on the Heating design tab of the Model option dialog.

 

In this case for summer design, the profile for Wednesday is used. If Wednesday is not a good choice for Summer design autosizing then you can instead define the profile explicitly using the Profiles design day definition method below.

 

Use End use default - apply the behaviour for the selected category as defined on the Model options on the Heating design tab.

 

2. Profiles - define both heating and cooling design day operation as a Profile. This option is more flexible and clearer than End-use defaults but can take slightly longer to set up.

 

Heating design day profile - the profile defining the schedule output during the heating autosizing design day.

Cooling design day profile - the profile defining the schedule output during the cooling autosizing design day.

Weekly and monthly variations

Other tools are available for rapid selection/deselection and setting of schedule data:
