Re: [EnergyPlus_Support] Type of slat angle control for blinds





There is a problem in the V4 release with that and will be fixed in the next release in April.

Sorry for the inconvenience.

Earlier versions had a slightly different problem with that and may not have been giving the correct result.  But the fix was flawed and we did not catch it until after release.

Dear EnergyPlus Group,
 
I am having problems with "slat angle control for blinds" option. I am using PurchAirWindowBlind.idf file from EnergyPlus 4.0 example files. I have slightly modified this file to run an annual simulation instead of a design day. There is a blind and a suitable control is defined in the file.
 
The problem is whenever I adjust the Type of slat angle control for blinds to BlockBeamSolar, the program crashes instanly, but it works fine if is set to FixedSlatAngle. Another observation, I have tried simulating the same example file from EnegyPlus 2.2 examples in Energyplus2.2  with BlockBeamSolar defined and it worked fine.
 
 
I was wondering if anyone has experienced a similar problem with slat angle control before. Is there a change on slat angle control definition in version 4.0? Since there is no error file is created I cannot understand where the error comes from.
