Hi all,
I?d like to have son points of view, advices or explanations about the issue i?m facing : i?m trying to find optimized slat angles (one tilt for each month of the year in fact) for exterior blinds (horizontal slats, for spaces facing south +/- 15°).
So :
- I 1st launched annual simulations with a shading control based on indoor temperature :
o WindowProperty:ShadingControl
o Shading control is schedules
o Schedule control type : always on (because the blind system is fully-switched the whole year, i just can move slats?tilt)
o OnIfHighZoneAirTemperature (i?ve done with setpoint 1 fixed to 24, 26 and 27°C)
o Slat angle control : ?BlockBeamSolar?
I look to the Output:Variable ?Window Blind Slat Angle? (monthly), and keep the values that match with good solar gains during winter and good solar protection during summer. Then i run a new file, in which i make a ScheduledSlatAngle, using the slats tilt found in the previous simulation (one value per month)
- i change the shading control as follow :
o schedule control type : always on
o Slat angle control : ?ScheduledSlatAngle?
The 2 simulations are matching correctly, but there's something i don't really get.
