In the time diagrams, the temporal course of temperatures (setpoint, actual value, etc.), humidity, CO2 concentration, heating and cooling loads as well as imposed thermal loads is shown for a selected period. The individual curves can be shown or hidden by check boxes. Some lines are only available for individual rooms, not when floors, zones or the entire building are selected, as these are only useful for individual rooms (e.g. temperature, humidity and CO2 content of indoor air).
You can select a period of time: a whole year, a certain month or a certain day of a selected month. This can be set in the box under Period. Depending on the selected period, different display values can be selected from a list.
By clicking on a diagram, it is given the focus (colored background). Now you have the possibility to move it with the left mouse button pressed. With the mouse wheel the resolution of the graphic representations can be increased and decreased. The button with the green arrow resets the zoom and shifting to the initial state. The button with the paper and the green arrow is used for CSV export. To save the individual diagrams as an image file, use the button with the image symbol and the green arrow.
There are also buttons for different days. A normal day is the calculated day that is as close as possible to the average valuesColdest and hottest day have the lowest and highest daily average temperature, respectively. The average temperature of the normal day is closest to the annual average temperature. The day selected by clicking is displayed.
The presentation of the results is divided into four areasfive sections:
Temperature
profilecurve [°C]
The individual loads can be shown or hidden using check boxes. Some lines are only available for individual rooms, not when floors, zones or the entire building are selected, as these are only useful for individual rooms (e.g. the temperature of the indoor air).
A negative load means cooling, a positive warming.
The perceived temperature is the mean value of the air temperature and the mean surface temperatures of the building components.
When calculating the air humidity, the latent cooling must be applied in addition to the condensation at the cold Here you can see the calculated indoor air temperature of a room. The perceived (operative) temperature is the mean value of the air temperature and the mean surface temperatures of the building components.
The outdoor air temperature from the climate data and the setpoint values of the air temperature for heating and cooling from the usage profiles can also be displayed.
Humidity curve [%]
If the humidity has been activated in the project options, the calculated relative humidity of the indoor air is shown here, as well as additionally the outdoor air humidity from the climate data. It should be noted that the relative humidity is strongly temperature-dependent and the absolute humidity of the indoor air is always higher than the outdoor air.
CO2 concentration [ppm]
The CO2 concentration of the indoor air calculated from persons and ventilation is shown here. In addition, limits of air quality ranges are given (from a 2008 announcement by the German Federal Environmental Agency): below 800ppm is high air quality, up to 1000ppm is medium, up to 1400ppm is moderate, and above 1400ppm is low air quality. According to the Workplace Ordinance, ventilation must be increased if 1000ppm is exceeded.
Heating and cooling load [kW]
The powers for heating and cooling are shown. If the plant capacity is limited, it is also possible to see what the heating/cooling demand is (in order to always maintain the setpoints) and what the room requires from the plant in order to reach the setpoint (slightly more than the demand if the room is already too cold or too warm).
When calculating humidity, latent cooling must also be applied to condensation on the cooling output. It should be noted that it is not a thermal load. ThereforeSo, of from the total cooling load, only the sensitive sensible part acts on affects the temperatures.
Thermal loads [kW]
Here you can see all other heat gains and losses. The loads caused by personssolar load is the heat gain due to solar radiation through the windows. The loads due to people, equipment and lighting (internal heat sources) are determined by corresponding usage profiles.
When evaluating the lighting load, consider the connection relationship with the lighting and sun protection control must be taken into account
The ventilation solar control.
Ventilation heat is calculated from the air volume and the difference between the outside outdoor and inside air temperatureindoor air temperatures. A negative load means cooling, a positive one means warming.
The building components take up absorb the sum difference of the other loads (heat capacity of the air is considered only considered for the air exchange). It should be noted that the calculation procedure takes into account the heat storage capacity of the walls is taken into account in the calculation procedure and that loads are absorbed by the walls and , if necessary, some of them are partially transferred to the outside. It is therefore not directly about the a direct heat conduction through the building components.For the selected building element, time diagrams, annual results or - if the humidity calculation is activated in the project options - also the comfort level are displayed on the right side, depending on the selection.
