IDA ICE 4.0 build 4 changelog

ICE 4.0 Build 4 released 2010-05-31

New in ICE 4 Build 4

• A new device was added: air-to-air air conditioner (in the list of fan
  coils). The same model (AirHeatPump) may also be used in AHUs.
  The parameters of AirHeatPump may be saved in the database.

• Clarification: Local AHUs and fan coils in a zone with mulplicity
  (i.e., where "Number of zones of this type" is not equal to 1) is
  simulated for one zone of this type. The water flows are multiplied
  outside of the zone calculation (in water split/merge model).

• 3 fan coils were added to the zone palette.

• The form for the default (empty) fan coil was changed. Links were added to setpoints.
  The minimal air flow for fan coil is now bound to "air_vmin" in
  system parameters.

• In forms for energy meters, the measured energy sources are now shown
  with their multipliers.

• The menu item "Remove point" now always removes one point. The old
  action in now renamed to "Align point".

• Supported non-surface heating/cooling devices (inserted in zone, not
  on surfaces).

• Added parameter "Longwave emissivity" to radiative heating/cooling
  devices (in old versions, the emissivity of the wall surface used).

• In version projects, the versions that become obsolete (require
  rebuild) are closed (to avoid showing wrong data).

• Variable temperature setpoints are now saved in the database with
  setpoint collections.

• The location object now contains an optional reference to a climate
  file associated with the location.
  In the building form, the field "Climate" may be set to "[default]"
  to use the location's climate file.

• New option "Add to shading objects" added to IFC import option. The
  default setting is off (in ocd versions it is always off).
  Still possible to switch shading calculation after import.
  Added warning when importing IFC with both options add to shadow and
  merge windows are active (the message not yet translated).

• Tooltip for connection lines includes values of connected variables.

• For interfaces without visible spots, the icon's border may be used
  insted of spot (in old version this was implemented only in the case
  when the icon had no connector spots at all).

• Added support for OBJ files and building geometry import.

• The simulation summary reports (the tables on the result pages) are
  now also available in outline view of zones. This makes it possible to add
  variables from summary reports to the project summary in version projects.

• In the default building, added new energy meter "Electric heating".
  It is used by "Electric heating coil" AHU.

• The default energy meter for equipment changed to "Equipment, tenant".
  This does not affect existing systems.

Changes in models

• CEWIND Fixed bug in light control (introduced in build 3).
  DETWIND

• CESIMZON Check for condensation and accumulate total time
  condensation occurs (as in CEDETZON).

• Emeter Fixed measurement units for power variables
  Emeter2 (only affect legends in diagrams).

• CESIMZON Radiative source (for connecting non-surface HC devices).
  CEDETZON Fixed energy form vapor emission from equipment.

• AirHeatPump New model implements an air-to-air air conditioner.

• STATSENS New measure options: 8 = Enthalpy, 9 = Hum. ratio,
  10 = Wet bulb. Removed local variables.

• SHADE Added output link for solar panels model.
  FACE Merged interfaces Ambient and VelLink.

• SIMBOIL Fixed calculation of Jacobian.

Changes in NMF Translator

• Supports for enumeration types.
  For a parameter with values 1,2,...N, it is now possible define names for these values.
  These names will be used in IDA Modeler insted of numerical values.

• in GLOBAL.NMF:
  EXTENSIONS
  ENUMERATIONS
  enum_type = (name_1, name_2, ...),
  enum_type_2 = ... ;
  END_EXTENSIONS

• in models:
  EXTENSIONS
  ENUMERATIONS
  param_name = (name_1, name_2, ...),
  param_name_2 = enum_type
  param_name_3 = ... ;
  END_EXTENSIONS

• Allowed list of strings as extension value.

• Allowed TRUE and FALSE as arguments of functions.

• Extension DefaultBound make the named variable(s) by default bound to their default values:
  EXTENSIONS
  DefaultBound var_name, var_name_2, ... ;
  END_EXTENSIONS

Fixed bugs

• Fixed bug in light control of window shadings (introdiced in build 3).

• When a local AHU was inserted from palette (not using ADD button),
  the values entered in the table of the zone's AHU was ignored. Now fixed.

• Removed the possibility to add multiple contours to the boundary of a zone
  or building part. IDA ICE not yet support such boundaries.

• Fixed flows and energy reports for local AHU and fan coils in zones with
  mulplicity.

• Fixed updating of shading building in 3D view after editing in site editor

• Fixed problems with causal connections between macro objects.

• Fixed some binding errors when copying models.

• Fixed "save as" for wall definitions.

• Fixed editing of feature position on property page.

• The "solar factor" was ignored in heating design simulation.
  Now it is ignored in cooling design simulation only.

• Fixed support of user-defined output files in control macros.

• Fixed hanging of program when "saving as" a resource.

• Fixed some problem in refreshing tables after changes.

• In IFC import: stable add-zone algorithm; fixed orientation.

• In IFC import: fixed bug in profile.

• In version projects, fixed saving changed version before saving base version.

• Fixed modeling of infiltration in case when the only external surface faced
  some direction was a roof part.

• Fixed removing directed connection with direction from macro object (the
  referenced variables was not plugged properly).

• In version project, when comparing versions the climate files was always
  marked as different. This made impossible to inherit change of climate file
  from parent version. Now the bug is fixed, but in the old version project
  every version still have own climate file.

• In version projects, the variable-level connections was not inherited in
  some cases. Now these cases are fixed.
