Buildings.BoundaryConditions.WeatherData

Weather data reader

Information

This package contains models to read weather data. It also contains an expandable connector called Bus that is used in the library to provide weather data to the different models.

Extends from Modelica.Icons.VariantsPackage (Icon for package containing variants).

Buildings.BoundaryConditions.WeatherData.ReaderTMY3

Reader for TMY3 weather data

Buildings.BoundaryConditions.WeatherData.ReaderTMY3

Information

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:

The latitude of the weather station, lat,
the longitude of the weather station, lon, and
the time zone relative to Greenwich Mean Time, timZone.

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 example, the parameter pAtmSou is used to change the source that is used as the atmospheric pressure. If pAtmSou=Buildings.BoundaryConditions.Types.DataSource.Parameter, the parameter value is used. If pAtmSou = Buildings.BoundaryConditions.Types.DataSource.Input, the input connector will be enabled and the value from the input connector will be used. If pAtmSou = Buildings.BoundaryConditions.Types.DataSource.File, the values from the weather file will be used.

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:
- When using TMY3 data from a file (e.g. 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.
- When using data from a parameter or from an input connector, the data must be in the SI units used by Modelica. For instance, the unit must be 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.

Implementation

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.
