Details on Pipe Run View
Information on Pipe run view dialog in radiator dimensioning.
You are here:
No.
Marks the pipe run and serves as a sorting criterion. Assign a clear number to each pipe run.
Name
Defines a name for the pipe run, e.g. southwest or ground floor.
Manufacturer and Model series
Shows the current radiator model and, if applicable, the manufacturer.
Supply water temperature
Determines the global supply temperature. The global supply temperature is used for all new pipe runs that are created. You can adjust the spread for each pipe run individually. If you change the global supply temperature, the pipe run supply temperatures will also change, unless they have been individually adjusted. If the supply or return water temperature is changed, the program indicates that the mass flow rates of the radiators also change and recommends a new design.
Return water temperature
Determines the targeted return temperature. Radiators are selected at dimensioning to ensure that the actual return water temperature is as close as possible to the targeted return water temperature, provided that the required output is achieved and the mass flow limits are observed. If you selected the Differential temperature fixed, heating cap. is determined as the design target, the calculated return water temperature of the radiator is identical to the target return water temperature of the pipe run. If the return water temperature is changed, the minimum spread is suggested appropriately. If the supply or return water temperature is changed, the program indicates that the mass flow rates of the radiators also change and recommends a new design.
Minimum differential temperature
Determines the minimum differential temperature in Kelvin, which should never be fallen below. The minimum differential temperature only has an effect if the radiator output is not sufficient and the return water temperature has to be raised above the preset return water temperature. If the target return water temperature is changed, the program suggests the minimum differential temperature accordingly.
Maximum differential temperature
Determines the maximum differential temperature in percent. The maximum differential temperature is given in percent, as it depends on the individual room temperature. The maximum differential temperature is entered and calculated as a proportion of the difference between supply temperature and room temperature. This prevents the return water temperature from falling below room temperature.
Table Pipe run view
| Column | Description |
|---|---|
| No. | Defines the sequential number of a radiator. |
| Location | Specifies the room name and the room number. The room number is comprised of the storey and room number according to the selected building structure. If you activated building sections and apartments, the column also shows the building section and apartment number. You can change the room name here. To change the room number, you have to switch to the general room data. |
| Qty. Rad. | Shows the quantity of radiators that are assigned to the pipe run. |
| WW | Defines the window width. If window dimensions are available from the detailed heat load calculation, the maximum length of the radiator is proposed accordingly. The maximum radiator length is calculated from the window width minus the installation reduction dimension. If no detailed heat load calculation is available and therefore no window areas have been entered, a window width can still be taken into account when dimensioning the radiators. You enter the window width at the Storey Overview and Quick Dimensioning page. This value is 1000 mm by default. |
| RC | Defines the reduced capacity of a radiator. |
| QRAD | Defines the standard heating output of a radiator. |
| Load | Shows the load of the radiator. |
| RH | Shows the radiator height automatically determined during radiator dimensioning. |
| RL | Shows the radiator length automatically determined during radiator dimensioning. |
| RD | Shows the radiator depth automatically determined during radiator dimensioning. |
| Blower level | Shows the blower level. Depending on the model, different blower speeds are available for convectors with blowers. You can restrict the blower levels for the dimensioning in the dimensioning options. With a higher blower level you achieve a higher heating or cooling capacity. However, the mass flow rate and noise level also increase. |
| BA | Determines, for models that can be used for heating and cooling, whether the dimensioning should be exclusively for heating or cooling, or only primarily for heating or cooling. If you select the Heating prior or Cooling prior setting, the system can also be used for cooling or heating, but the system will be optimized for heating or cooling. If you select the Only heating or Only cooling setting, the capacity will not be used to cover the cooling load or heat load. The valve settings are then optimized for the respective case. |
| Type | Shows the type of the radiator. |
| Diff. temp. fix | Shows whether the setting Differential temperature fixed, heat capacity is determined or Heat capacity fixed, differential temperature is determined is activated for the radiator. |
| tr | Shows the calculated return water temperature. The return water temperature is variable at the radiator and is always determined depending on the desired radiator capacity. This results in a mass flow rate which has to be adjusted via the control valve on the radiator. The calculated return water temperature is usually lower than the desired return water temperature (radiator has overcapacity). If the radiator capacity of the largest possible radiator according to the specifications for the construction height and window width is not sufficient for the desired heating load, the program tries to raise the return water temperature within practical limits. If you selected the Differential temperature fixed, heat cap. is determined option in the radiator preselection, the displayed return water temperature is always identical to the pipe run return water temperature. |
| m | Shows mass flow rate of a radiator. |
| LP | Shows the calculated sound pressure level when using fan convectors. |
| ! | Indicates an error. |
