(This post is slightly related to my previous post about SwimmingPool:Indoor.)
I want to use LoadProfile:Plant in conjection with many Coil:Heating:Water objects in a hot water plant loop as shown below.
I already know 8760 hours of load profile for LoadProfile:Plant, but the entire load in the hot water loop is unknon. So, I want to simulate sizing run and autosize the boiler, pump and heating coils.
LoadProfile:Plant is used with ScheduleFile. I also know the load profile for LoadProfile:Plant on WinterDesignDay and SummerDesignDay. However, the load profile on DesignDays cannot be input to ScheduleFile. How can I set set load of LoadProfile:Plant on DesignDays?
According to Application Guide for EMS, it seems that "CurrentEnvironment == 1" represents WinterDesignDay when WinterDesignDay is Obj1 of SizingPeriod:DesignDay. I tried to override ScheduleFile during the sizing run with EMS, but my EMS input does not work for now. During the design days, EnergyPlus refers to loads on the same date as the sizing day in ScheduleFile i.e. load on January 21st for WinterSizingDay in my case.
I would appreciate it if anyone could correct my EMS input below or advise any other way to set LoadProfile:Plant on DesignDays.
