• IISiBat will tell you about warnings / errors

5
TRNSYS 16 Kernel

• Improved numerical solver
• New solver with numerical relaxation
• Improved numerical precision
• Double precision variables
• Small time steps (1 sec)
• Clean coding practices
• Implicit none
• Data modules instead of common blocks
• New error message handling
• Separate routine
• Types send Error number OR string

6
TRNSYS 16 Kernel (2)

• DLL architecture
• Add a new component drop a DLL in a folder
• Types written in any language!
• Call to external programs
• Call to EES
• More than one component
• Call to Matlab

7
Standard Component Library

• Combined Data Reader/Solar Radiation Processor
• Very frequent error cause
• Hydrogen Systems Components
• HYDROGEMS Library included in standard package
• Improvements to HYDROGEMS
• New SOFC model
• Improved thermal modeling
• Improved control library
• PID controller
• 5-stage thermostat

8
Standard Component Library

• New HVAC components
• Proportional Furnace
• Variable Speed Pump
• New Absorption Chiller Model
• Etc.
• Enhancements to existing components
• More flexibility for data reading
• More robust Storage Tank model (Type 60)

9
TRNSED

• Improved navigation inside the TRNSED file
• Multiple windows or HTML-like anchors
• Clickable areas in pictures
• Improved usability for developers
• Menus to insert TRNSED features (e.g. check box)
• Recallable default values
• Interaction between TRNSED variables
• E.g. selecting a line in a pull-down menu will
  change another displayed variable

10
DLL Architecture

11
DLL Architecture what is the advantage ?

• Memory issue trnlib.dll is getting too big.
• Only load the Types that are needed.
• Many non-standard libraries.
• Transsolar no-standard types, TESS Libraries,
  Hydrogems, User Components.
• Allows for easier updates.
• Non Fortran Language Types may be used.
• Shorter recompilation time.

12
DLL Architecture how does it work ?

• After reading the deck, TRNSYS calls subroutine
  LoadLibrary.
• LoadLibrary searches the UserLib directory for
  DLLs and loads any that are found.
• LoadLibrary searches each DLL for exported
  subroutines that have Type in their name.
• LoadLibrary compiles a list of pointers to each
  exported subroutine.
• Instead of calling Types, TRNSYS calls each
  pointer in the list.

13
DLL Architecture what do I need to do ?

• One new line of code must be added to each Type

!DECATTRIBUTES DLLEXPORT TYPExxx
14
DLL Architecture what are the disadvantages ?

• Setting up a Compaq Visual Fortran workspace is
  more complicated.
• TRNSYS now comes with a ready made workspace.
• Debugging in the Developer Studio is more
  complex.
• Be careful of which project is active when you
  recompile.
• You can only set breakpoints in the active
  project.

15
IISiBat 4Plans for TRNSYS 16

• New, DLL-based software architecture optimized
  for Windows XP/ME (but still supporting Windows
  95, NT, 2000)
• New equipment-oriented features
• Better integration of the building model (better
  connection with PREBID / TYPE 56)
• New connection editor
• New wizards
• New developer in the team
  Paul SETTE

cooled ceilingNew Features of TYPE 56

• Integration of a cooled ceiling model in TYPE56
• according to norm for cooled ceiling tests (DIN
  4715-1)

24
cooled ceiling New Features of TYPE 56

• advantages
• integrated in TYP56
• heat exchange with zone is taken into account
• heat transfer to the fluid is taken into account
  
• Library of cooled ceilings tested and available
  on the market

25
Two band model for windows New Features of TYPE
56

• currently one band model for windows

26
Two band model for windows New Features of TYPE
56

• New Two band model for windows

27
cooled ceiling New Features of TYPE 56

• automatic segmentation (internal Loop input
  /output for TYPE56)

• minimum specific mass flow needed for linear
  approximation of e-function
• gt several serial segments are needed. Now these
  segments are connected
• automatically (Tout1Tin2, Tout2Tin3,
  mflow1mflow2mflow3)

28
cooled ceiling New Features of TYPE 56
