Input Data
Building geometry passed automatically from Modelling IT Room
dimensions and connectivity Co-ordinates of Windows, doors
and holes used as MacroFlo openings.
Assignment of opening properties to Windows and doors using a simple and efficient editing process based on opening types.
Opening Properties
Wind exposure
Crack dimensions and flow characteristics
Free opening area
Timing and degree of opening
Opening controls, expressed as functions of weather variables
and conditions in any room.
Hourly Wind speed, Wind direction and external air density
from weather file.
Data from ApacheSim and ApacheHvac building simulation and system Thermal parameters is used in tandem with MacroFlo.
Modelling
Uses a fast multi-zone thermo-fluid solver to simulate the interaction between air flows, pressures and Thermal conditions Cross-ventilation incorporates models of:
External wind pressure based on empirical data
Stack effect (buoyancy)
Flow characteristics of cracks
Flow characteristics of large openings
Two-way flow
Resistance due to grilles and wall friction
Rayleigh instability
Supported by full documentation on methodology.
