Buildings.BoundaryConditions.WeatherData.ReaderTMY3
This component reads TMY3 weather data (Wilcox and Marion, 2008) or user specified weather data.
The following parameters are automatically read from the weather file:
lat,
lon, and
timZone.
By default, the data bus contains the wet bulb temperature.
This introduces a nonlinear equation.
However, we have not observed an increase in computing time because
of this equation.
To disable the computation of the wet bulb temperature, set
computeWetBulbTemperature=false.
This model has the option of using a constant value, using the data from the weather file, or using data from an input connector for the following variables: atmospheric pressure, relative humidity, dry bulb temperature, global horizontal radiation, diffuse horizontal radiation, wind direction and wind speed.
By default, all data are obtained from the weather data file,
except for the atmospheric pressure, which is set to the
parameter pAtm=101325 Pascals.
The parameter *Sou configures the source of the data.
For the atmospheric pressure, dry bulb temperature, relative humidity, wind speed and wind direction,
the enumeration
Buildings.BoundaryConditions.Types.DataSource
is used as follows:
Parameter *Sou
|
Data used to compute weather data. |
|---|---|
| File | Use data from file. |
| Parameter | Use value specified by the parameter. |
| Input | Use value from the input connector. |
Because global, diffuse and direct radiation are related to each other, the parameter
HSou is treated differently.
It is set to a value of the enumeration
Buildings.BoundaryConditions.Types.RadiationDataSource,
and allows the following configurations:
Parameter HSou
|
Data used to compute weather data. |
|---|---|
| File | Use data from file. |
| Input_HGloHor_HDifHor | Use global horizontal and diffuse horizontal radiation from input connector. |
| Input_HDirNor_HDifHor | Use direct normal and diffuse horizontal radiation from input connector. |
| Input_HDirNor_HGloHor | Use direct normal and global horizontal radiation from input connector. |
Notes
In HVAC systems, when the fan is off, changes in atmospheric pressure can cause small air flow rates
in the duct system due to change in pressure and hence in the mass of air that is stored
in air volumes (such as in fluid junctions or in the room model).
This may increase computing time. Therefore, the default value for the atmospheric pressure is set to a constant.
Furthermore, if the initial pressure of air volumes are different
from the atmospheric pressure, then fast pressure transients can happen in the first few seconds of the simulation.
This can cause numerical problems for the solver. To avoid this problem, set the atmospheric pressure to the
same value as the medium default pressure, which is typically set to the parameter Medium.p_default.
For medium models for moist air and dry air, the default is
Medium.p_default=101325 Pascals.
Different units apply depending on whether data are obtained from a file, or from a parameter or an input connector:
USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.mos), the units must be the same as the original TMY3 file used by EnergyPlus (e.g.
USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw).
The TMY3 data used by EnergyPlus are in both SI units and non-SI units.
If Resources/bin/ConvertWeatherData.jar is used to convert the .epw file to an .mos file, the units of the TMY3 data are preserved and the file can be directly
used by this data reader.
The data reader will automatically convert units to the SI units used by Modelica.
For example, the dry bulb temperature TDryBul in TMY3 is in degree Celsius.
The data reader will automatically convert the data to Kelvin.
The wind direction winDir in TMY3 is degrees and will be automatically converted to radians.
Pa for pressure,
K for temperature,
W/m2 for solar radiations and
rad for wind direction.
The ReaderTMY3 should only be used with TMY3 data. It contains a time shift for solar radiation data that is explained below. This time shift needs to be removed if the user may want to use the ReaderTMY3 for other weather data types.
To read weather data from the TMY3 weather data file, there are two data readers in this model. One data reader obtains all data except solar radiation, and the other data reader reads only the solar radiation data, shifted by 30 minutes. The reason for this time shift is as follows: The TMY3 weather data file contains for solar radiation the "...radiation received on a horizontal surface during the 60-minute period ending at the timestamp." Thus, as the figure below shows, a more accurate interpolation is obtained if time is shifted by 30 minutes prior to reading the weather data.
