Hello Users, I use IDF Editor for my building. I want to add an ZoneHVAC:IdealLoadAirSystem to one of the zones. This system is just for heating. The set temperature in the zone is 21°C. If the outside temperature is over 15°C the heater is off. I know how I have to define the schedules for the set temperature but what is the easiest way to add the shut down temperature of 15°C? Regards, Arne
One option is to create an EMS program that actuates the Availability Schedule of the ideal air system. The EMS program should use a calling point that occurs early in the zone timestep, and would set the availability schedule to off or on based on the outdoor drybulb temperature (retrieved via an EMS sensor).
Thanks for your answer! But is there a way to do that in the IDF Editor, without creating a program?
You could pre-process the weather file, find the hours where outside temperature is above 15C, and create a detailed ideal system availability schedule to reflect that.
Okay I thought there is maybe a easier way with less work.
