Details on Limit Surface Temperatures
Information about the Limit surface temperatures dialog.
Allows to adjust the maximum allowable surface temperatures, which are taken into account when designing the surfaces with systems. The maximum permitted values are normally not exceeded during automatic design or a warning is displayed in the Log window.
You are here:
The limit surface temperatures of the individual components (floors, ceilings and walls) can be adjusted. Limit surface temperatures for floors in bathrooms and border zones can be determined separately for panel heating. For surface cooling, the fields for floors in bathrooms and border zones are deactivated.
The suggested values are specifications from standards or values agreed with the manufacturers.
The limit surface temperatures should not be modified without expert knowledge and not without consulting the system suppliers as well as the executing companies.
Consider temperature excesses in feed pipes during dimensioning
Enabled: If the limit temperature is exceeded in the feed pipes, the output is reduced to counteract the exceeding of the limit temperature. If the limit temperature is nevertheless exceeded, a message is displayed in the Log.
Limit exceedances often occur in corridors with closely spaced feed pipes. This can result in subsequent heating circuits no longer providing the expected output.
You can locate the points and show the respective feed pipes as insulated by reducing the power output in the Phi proportion column in the room view, so that the heating circuits once again provide the expected output. Alternatively, you can reduce the installation distances of the feed pipes.
Deactivated (default setting): The temperature limits in the feed pipes can be exceeding during the dimensioning and a message concerning this will be is output in the Log .
Standard: Restores the default setting.
