Description

Hydraulic control loop is the element used to hydraulically balance and regulate (qualitatively or quantitatively) the thermal efficiency of the end receiver (e.g., fan-coil or cooling beam). The article describes the ways of applying the element in the program.

Location in program

Hydraulic control loop is presented in the program as a separate module, the availability of which is visible in the InstalSystem 5.5 Manager / Help tab / list of Modules available in current licence configuration:

1. Hydraulic control loop module.

To use the Hydraulic control loop element, the corresponding catalogues should be selected and added to the project in the General data window / Catalogues tab. For more information, see: Selecting catalogues for the project.

2. Hydraulic control loop Catalogues.

The element can be placed on the drawing when Convectional, Rad.-floors,walls or Rad.-ceilings editing scope is active:

• clicking the icon Hydraulic control loop in the Distribution - thermal installations tab in the Main tools menu:
  

  

  3. Hydraulic control loop icon.

  
  
• clicking the icon with schemes presented by the particular producers:
  

  

  4. Hydraulic control loop schemes.

  
  

Examples of use

Hydraulic control loop is a prefabricated block of grouped elements and is not graphically editable. May include a pump, balancing valves, control valves and overflow-relief valve. Allows the use of valves and fittings only from a list of items, suitable for use in a given location, in a configuration precisely defined by producers.

Use

The Use of the Hydraulic control loop is determined in accordance with the Project scope indicated in the General data window:

• Heating,
• Heating and cooling efficiency.
