Description

The article describes the ways of using such elements as Pump and Mixer / Pump unit in Designing heating systems with convective radiators and Designing of radiant heating floor and wall installation.

Location in program

Elements Pump and Mixer / Pump unit are available in the Distribution - thermal installations tab in the Main tools menu, when Convectional, Rad.-floors,walls or Rad.-ceilings editing scope is active.

1. Pump and Mixer / Pump unit .

Examples of use

Pump

The Pump is inserted as a separate element on the pipe-run section.
The following data can be adjust, if necessary, in the Data table window:

• H - Pump head;
• Rotation angle.

If the Pump head is left to be sized by the program, the result can be read from the hint after performing Calculations of Heating systems:

• In the table, displayed in the working space,
• On the element Label:
  

  

  2. Pump.

  
  

Note: The appearance of the Label can be modified according to personal preferences. For more information, see: Label editing.

• In the Results tables:
  

  

  3. Pump in the Results tables.

  
  

(Optionally) Use manufacturer catalogues or sizing software to select the particular Pump model and adjust its characteristics.

Mixer / Pump unit

The Mixer / Pump unit is inserted as a group of elements, defined depending on the project purposes. The unit can be neutral or from the particular manufacture, selected from the Catalogues provided in the program. Note: To insert the Mixer / Pump unit element, use one of the following ways:

• Place the Mixer / Pump unit element on an already drawn pipe-run using the function Insert dividing point and deleting unnecessary pipe-runs.
  
  
  
• Draw sequentially the pipe-runs and the Mixer / Pump unit element.
  
  

Orientation

The Orientation of the Mixer / Pump unit is selected in the Data table window from the available variants.

4. Mixer / Pump unit Orientation.

Use

The Use of the Mixer / Pump unit is determined in accordance with the Project scope indicated in the General data window:

• Heating,
• Heating and cooling efficiency.
  
  

Type

The Type of the Mixer / Pump unit can be chosen from the:

• Neutral catalogue Standard mixers, pump and bypass units, provided by the program. Depending on the use of the Mixer / Pump unit , there are three variants be selected:
  • Mixing supply and return units,
  • Pump units,
  • Units with supply to return bypass.
    

    

    5. Mixer / Pump unit Type.

    
    
• Catalogues, provided by the particular manufacturer, selected in the General data window / Catalogues tab. For more information, see: Using catalogues and catalogues data in the project.
  
  

2D/3D view style

Presentation 2D and Presentation 3D of the Mixer / Pump unit can be:

• Detailed,
• Simplified.

The dimensions of the Mixer / Pump unit can be modified, if necessary.
