This component reads TMY3 weather data (Wilcox and Marion, 2008) or user specified weather data.
The weather data format is the Typical Meteorological Year (TMY3)
as obtained from the EnergyPlus web site at
http://apps1.eere.energy.gov/buildings/energyplus/cfm/weather_data.cfm. These
data, which are in the EnergyPlus format, need to be converted as described
in the next paragraph.
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:
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.
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:
The TMY3 weather data, as well as the EnergyPlus weather data, start at 1:00 AM
on January 1, and provide hourly data until midnight on December 31.
Thus, the first entry for temperatures, humidity, wind speed etc. are values
at 1:00 AM and not at midnight. Furthermore, the TMY3 weather data files can have
values at midnight of December 31 that may be significantly different from the values
at 1:00 AM on January 1.
Since annual simulations require weather data that start at 0:00 on January 1,
data need to be provided for this hour. Due to the possibly large change in
weatherdata between 1:00 AM on January 1 and midnight at December 31,
the weather data files in the Buildings library do not use the data entry from
midnight at December 31 as the value for t=0. Rather, the
value from 1:00 AM on January 1 is duplicated and used for 0:00 on January 1.
To maintain a data record with 8760 hours, the weather data record from
midnight at December 31 is deleted.
These changes in the weather data file are done in the Java program that converts
EnergyPlus weather data file to Modelica weather data files, and which is described
below.
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.
