IDA ICE 4.5.1 changelog

ICE 4.5.1 Released 2013-05-21

New in ICE 4.5.1 (rel. to ICE 4.5)

• The table "HVAC systems" is replaced with "Air handling units".
  Added columns [not yet translated].

• Added DewPoint signal to "zone proxy" (available in custom control macros).

• Added DewPoint and Daylight signals to zone sensor.

• The "Occupancy" signal in "zone proxy" is now not smoothed.

• "Occupancy time" in reports replaced with "In use" time that is the time when
  the "In use" signal is >= threshold (a system parameter, default 0.01).
  (In version 4.5 the "In use" time was only used as input signal for control macros).
  By default, the "In use" signal is the maximal value of non-smoothed occupancy
  schedules of occupants with non-zero number of people (same as in "zone proxy").

• The fan coils macros now use "proxy" models to get input signals.

• Possibility to break on log message (to send bug report)
  Right-click the message, select "Interrupt next time at this message" and
  repeat the operation that produces the message.

• Losses in DHW loop in ESBO plant are modelled by increasing the water flow
  (assuming the clients will use more hot water when mixing hot and cold water).

• The initial size of views is now limited:
  for forms with flexible size: 1.5 * nominal size
  for views with undefined size (HTML, outline): width <= 8", height is not limited.

• Added possibility to search for more than one word in Find objects.

• Required confirmation when removing a version from project.

• Added the possibility to invoke ESBO plant.

• Added the possibility to download iw2-files.

• New category of energy meters: "HVAC other".
  Used for fan in gas boiler.

• Now IDA ICE does not ask repeatedly for missing climate file. Also stores mean TAir of climate file
  to use it for ground model when the climate file is not available.

• Added documentation for the tables on the "General" pages (for zone and building)
  and on the "Results" page

Changes in models and functions called from models

Adder The type of parameters changed to GENERIC (to allow parameter mapping).
AdderA

Limiter Fixed restriction for lower limit. In the Modelica code the uMin.max=uMax
LimPID that cannot be supported in IDA. The restriction replaced with assertion
uMin<=uMax.

AHUctrl Replaced with enhanced version.

CEDETZON Fixed bug in SW radiation from lighting.

CEDETZON Added new local variable for report: CO2emiss = total CO2 emission in
CESIMZON zone (from occupants and equipment) [mg/sec].

TankStrat Shunts at pairs of input/output-links.
Pairs must have the same mass flow in and out.

GHX_SLin Revised version.

Emeter2 Fixed case of input signal with mixed sign and negative multiplier.

CalcShad Rewrote the routine to work in a coherent way.
Also removed small (transformed) solar elevations
for internal light distribution due to large
inaccurancies in the shading.

CEColPln Removed unused variable ExpLoc.
CEBeam
HCpnl

PMTMultiM Increaced value of mmin during linearization.

CELVO Time constant on Rho1 and Rho2. Top and Bot expressions modified.
MLVO

Fixed bugs

• Fixed "VAV, scheduled" (did not work if the schedule was not used otherwise).

• Fixed pasting "No central AHU" to multiple cells in the table "Zones".

• Fixed "Air (5%) / Krypton (95%) Mix - EN673 (WIN7)" in the Window7 database.

• Disabled erroneous inserting of features into a building when the users double
  click them in the palette instead of dragging to a face in 3D view.

• Fixed resizing of main window on multiple monitors.
  Maximizing to all monitors is not possible now (unless the video card defines
  all screens as a single display). Instead, the window may be resized manually
  to the required size.
  The pop-up messages are now shown on the same monitor as the main window.

• Fixed floor area for ground model - it was not accurate for corner zones in case
  of very thick walls.

• Fixed opening array parameter from modal forms. It was shown in a non-modal form
  behind the modal parent form. Now it is show in a new modal form.

• Fixed showing airflows on wall totally covered by windows.

• Disabled inserting skylight on sloping roof.

• Fixed holidays: sometimes it did not work in short simulations.

• Fixed opening objects from model dialog (sometimes one opened a copy of the same
  modal dialog).

• Fixed cooling energy meter in "Return air humidity control (steam)" (the
  variable StInjCtr.QTot was included by mistake).

• Fixed: the simulation period sometimes shown as 24 hours even if it was different.

• Fixed error in 3D when editing PV in ESBO plant.

• Fixed message about missing energy meter (referred by mistake to the default meter).

• Fixed erroneous small negative EXT-WALLS-AREA (used for thermal bridges).

• Losses in DHW loop in ESBO plant were ignored. Now fixed.

• The comparative report crashed when one tried to show produced energy. Fixed.

• Fixed crash of network licenses on some virtual machines.

• When using stand-alone license together with network licenses, the checkout dialog
  did not show the local license in the count. It still does not, but it now says
  that it shows network license instead of licenses.

• Fixed upgrading the maintenance.

• Fixed visualization of window properties for sloping windows.

• Fixed design massflow for brine pump in ESBO plant - it was wrong when served from
  boreholes.

• Fixed plot line properties for duration diagrams.

• Fixed Int.Shading column in the table of windows (it was not possible to open and paste).

• The plot line markers were different in the diagrams and in the legends - in the case
  when not all variables were shown as plot lines. Now fixed.

• Fields showing protected parameters were not always read-only. Fixed.

• Fixed error in calculating geometry of non-rectangular features on cycle-connected
  floor/ceiling.

• When a cycle-connected floor/ceiling was completely filled by a feature on the
  floor side, it was not shown in 3D on the ceiling side. Fixed.

• Fixed size parameters of non-rectangular heating and cooling devices.

• For "flipped" zones (with walls in counter-clockwise order), the features was inserted
  and shown on floor plan in wrong positions. Now fixed.

• Fixed the link to PAmb in the palette, page Ambient (was linked to TAmb).

• Connections to references worked only when connected to algorithmic input
  (e.g., did not work when connected to AIRMUX model).

• Compass angle was disregarded in the Indata report (windows table).

• Fixed a crash in 3D with IFC.

• Fixed some links in the online documentation.

• Fixed binding of variables to parameters in resources stored in version projects.

• Fixed a bug in the building geometry import.

• Fixed bug: Wall parts were not included in the internal distribution of direct light.

• The air flow arrows was pointing in the wrong direction for leaks on floors.

• Fixed some bugs in the Input data report.

• Maintenance expiry date was wrong if rw-memory is earlier than feature expiry date.

• External shades defined on facade windows were shown on wrong height in 3D.

• Fixed a crash in the Indata report if plane roof windows/skylights were used.

• Fixed a bug with network licenses.

• Fixed a problem with solar shading from balconies when building rotated on site plan.

• Some pumps and fans in the ESBO plant were not included in the systems report.

• The IN variables that are members of output links (e.g., TAirIn in HCEL model)
  were bound to start values when copied.

• "Restore link" did not work in modal dialogs.

• When replacing an AHU from script, the new schema was not loaded.

• The power consumption in FreeSupCtr is now counted as pumps, not as cooling.

• Fixed the "Special controller steam humidifier" AHU.

• Fixed bugs in shading calculation and internal light distribution.

• Fixing shading of solar panels.

• Fixed absorbtion of SW ratiadion from lighting (bug introduced in ICE 4.5).

• The closed doors inserted in faces were modelled as adiabatic walls (not connected to the face).

• Ensure that the TOffset model ("similar + offset") does not override MISCMEASLINK used by other client.

• Fixed solar shading from imported geometry on tilted windows.

• Fixed the replacing of macro via clipboard.

• Fixed the mapping of the default generator efficiencies in the invoked ESBO plant.

• In the "Zone totals" table, the closed doors were counted twice: as walls and as doors. Now only as doors.

• The suface area in the table "Surfaces" now does not include windows and doors inserted
  from both sides of the wall.

• The condensation heat removed by fan coils was not included in the summary tables. Now it is included.
