Fittings

Enters fittings for the water distribution system.

When entering fittings, the following parameters must be specified:

• Reference
• Selection
  The program selects and imports data from the "Library of generic elements" using the wizard on the right-hand side.

Library of generic fittings

The "Library of generic elements" option, within the "Project" group, is used to create and edit the libraries of available generic fitting types.

The data associated with each type of fitting is as follows:

• Reference
• Description
• Graphical representation
  Accesses the symbol library available from "General options" via "Symbols for drawings" in the "Project" group of the general interface.
• Element pressure drop (Flow coefficient, Kv / Localised pressure loss)

Accumulator tank

Inserts accumulator tanks.

When entering accumulator tanks the following parameters must be indicated:

• Reference
• Selection
  The program selects and imports data from the "Library of generic elements" using the wizard on the right-hand side.

Library of generic accumulator tanks

The "Library of generic elements" option, within the "Project" group, is used to create and edit the libraries of available generic accumulator tank types.

The data associated with each type of accumulator tank is as follows:

• Reference
• Description
• Characteristics
  • 2 outlets (Capacity; Pressure loss)
  • 4 outlets (Capacity; Pressure loss, primary circuit; Pressure loss, secondary circuit)
• Dimensions (Diameter; Height; Inlet position)

Pump

Inserts circulation pumps.

When entering a pump, the following parameters must be specified:

• Reference
• Selection
  The program selects and imports data from the "Library of generic elements" using the wizard on the right-hand side.

Library of generic pumps

The "Library of generic elements" option, within the "Project" group, is used to create and edit the libraries of available generic fitting types.

The data associated with each type of pump is as follows:

• Reference
• Description
• Flow/pressure curve
  • Midpoint (Flow; Pressure)
  • Dotted (Flow; Pressure)
• Dimensions (Height; Width; Length; Inlet position)

Library of generic heat exchangers

The "Library of generic elements" option, within the "Project" group, is used to create and edit the libraries of available generic fitting types.

The data associated with each type of heat exchanger is as follows:

• Reference
• Description
• Characteristics
  • Power
  • Performance
  • Capacity
  • Pressure loss (Localised pressure loss / Flow coefficient, Kv / Depending on the flow rate)

Expansion tank

Inserts expansion tanks.

When entering an expansion tank, the following parameters must be specified:

• Reference
• Type
  • Open
    Tank expansion vessel open to atmosphere.
  • Closed
    Closed tank expansion vessel, containing a volume of air and water in contact with each other.
• Diaphragm
  A diaphragm tank expansion vessel, which has a flexible inner membrane separating air and water.

By clicking on "Calculate", the program collects the minimum and maximum temperature and the volume of fluid in the system from the associated installation and provides the required capacity of the expansion tank according to its type.

Indoor hydraulic unit

Enters indoor hydraulic units.

A hydronic indoor unit is a commercially available unit that brings together all the hydraulic fittings required in domestic aerothermal systems, such as the circulation pump, expansion tank or storage tank, under the same housing.

This means that to use these fittings, only this unit needs to be connected between the air-to-water heat pump and the circuit inside the building.

When entering a hydraulic indoor unit, the following parameters must be specified:

• Reference
• Selection
  The program selects and imports data from the "Library of generic elements" using the wizard on the right-hand side.
• Operating mode (Cooling (optional); Heating (optional))
