Introduction
TileFlow Standard and TileFlow Plus
General Enhancements
Features Related to the Calculation of Above-Floor Airflow and Temperatures
Introduction
The major enhancement in TileFlow version 3.0 is the capability to calculate airflow pattern and temperature distribution above the raised floor. The new features in this version are primarily related to
the input required for this capability and to the viewing of the results. To accommodate the new commands and toolbar buttons, the menus and toolbars have been reorganized.
TileFlow Standard and TileFlow Plus
Starting from Version 3.0, TileFlow will be available in two variants: TileFlow Standard and TileFlow Plus.
TileFlow Standard gives you the capability to set up under-floor models, solve them, and display the results. In addition, it allows you to set up above-floor models, but does not let you solve them.
TileFlow Plus gives you the full capability of the program. It allows you to set up under-floor and above-floor models, solve them, and display the results.
Screen Capture Facility
The screen capture command (File > Screen Capture) allows you to save the TileFlow workspace as a bitmap file.
Print Utility
The print quality has been significantly improved.
Turn Tool
This tool allows you to rotate the 3D view about the vertical axis.
Tilt Tool
This tool allows you to tilt the 3D view.
Tools for End Views
These tools allow you to display the 3D view as YZ end view, XZ end view, or top view.
Rotate View Continuously
This new command allows you to rotate the 3D view continuously. By default, the view rotates at the standard speed. You can, however, speed up or
slow down the rotation speed.
Enhanced Definition of No-Flow Region
You can now specify the vertical extent of the no-flow region. A no-flow region can cover only the space under the raised floor, both the
under-floor and above-floor spaces, or only the space above the raised floor.
Above-Floor Vertical and Horizontal Partitions
TileFlow now gives you the tools to include above-floor partitions in your simulation. These partitions affect only the airflow pattern and
temperature distribution above the raised floor; they have no effect on the distribution of airflow rates through the perforated tiles.
Above-Floor Solid Blocks
TileFlow now gives you the ability to include above-floor solid blocks in your simulation. These solid blocks are passive (i.e., they have no heat
load) and can be used to represent file cabinets and other passive objects; they can also be used to create variable ceiling height.
Enhanced Definition of Server Rack Styles
The definition of server rack style has been modified to include the airflow direction, the airflow requirement, and the acceptable maximum inlet
temperature.
The available airflow directions are:
- Front to Rear. Cold air enters through
the front face and the hot air is expelled from the rear face.
- Front to Top. Cold air enters through
the front face and the hot air is expelled from the top face.
- Bottom to Top. Cold air enters through
the bottom face and the hot air is expelled from the top face.
- Front, Rear, and Bottom to Top. Cold
air enters through the front, rear, and bottom faces and the hot air is expelled from the top face.
- Front to Rear and Top. Cold air enters
through the front face and the hot air is expelled from the rear and top faces.
TileFlow gives you three options for specifying the airflow requirement of a rack.
- You can use the TileFlow estimate based on the heat load. This estimate uses a relationship, derived from available data for a
large number of servers, between the heat load and temperature rise across the rack.
- You can specify a temperature rise across the rack. TileFlow will calculate the airflow rate from the heat load in the rack and
the specified temperature rise.
- You can specify the value of the airflow rate (in cfm) itself.
Calculate Above-Floor Airflow
This command starts the calculation of above-floor airflow and temperatures.
Plot Above-Floor Results
This command launches a separate plot interface, where you can display the velocity vectors and temperature distribution in vertical planes along
rows, vertical planes along columns, and horizontal planes. You can save these results in various file formats (bitmaps, tiff, jpeg, and png).
Display Temperature Fog
This command displays the three-dimensional temperature field above the raised floor, in the 3D view of the TileFlow workspace.
Show the Rack Overheat Warning Lights
This command flashes warning lights on racks that satisfy the given overheat criterion (or criteria). The overheat criterion can be based on the
rack inlet temperature, rack exit temperature, or the acceptable maximum inlet temperature specified in the rack style. The first two criteria are global (one setting applies to all racks); the third is local and varies from rack to rack. The overheat criteria are specified in the Select Rack Overheat Conditions dialog box, which appears when you invoke the Show the Rack Overheat Warning Lights command.
Temperature Billboards
TileFlow allows you to view velocity vectors and temperature distribution on vertical and horizontal billboards. You can pick a billboard along a
column (YZ billboard), along a row (XZ billboard), or along the height (XY billboard). By default, a billboard shows both the velocity vectors and temperatures. You have the option of removing the velocity
vectors.
Thermometer Tool
The thermometer allows you to display local temperatures over a temperature billboard.
Animation of Above-Floor Air Movement
This facility allows you to view the movement of air above the raised floor. It displays the trajectory of particles originating from the midpoints
of perforated tiles. The trajectory is color-coded according to the local temperature.
