Fan Coil Selection Software 

Our FCU selection software provides a rapid means of preparing high quality, well presented quotations for fan coil units.

It is a configurable software package available either as a desktop or cloud-based system. The way in which the software operates is fixed, however the database makes the software very flexible.

Users can choose an FCU model and select the coil they want in the model based on available options for that unit and then select the entering air and water conditions. They will then be able to run a coil performance calculation which gives leaving air and water conditions, cooling/ heating capacity, and fan power consumption. The calculation can be based on the manufacturer’s interpolation of test results available and correction factors for the entering conditions.

The software operates in two ways:

Rating – Calculates maximum performance for units chosen (via speed, sizes, coils) for a given set of conditions.

Selection – Returns the units that are capable of performing the entered duty within the limits specified by the user.

FCU Software Process

1. Splash Screen

As the system is initiated, a boot-up dialog (or “Splash Screen) is displayed and replaced with our client’s logos and branding.

2. Project Details

This initial screen is where the selection commences and ends. The operator selects which range and configuration of unit is to be used as well as which sizes and speeds are to be considered.

3. Templates

Templates can be set up to provide default values and options for a selection for different consultants, customers or for standard settings for various applications.

4. Selection

This screen enables the operator to enter the Cooling and/ or Heating design conditions against which the unit is to be selected.

5. Coil Performance

There are two variants of the software. One uses a generic coil performance module, the other uses a database of performance values similar to those that might be found in a catalogue.

6. Fan Performance 

The Volume / Pressure performance data of the fan(s) within each unit will be held in amendable data files in a matrix type format of volume against pressure.

7. Ancillaries and Options

Once a suitable unit has been selected, the construction options and ancillaries can be selected, and the software then returns to the initial “Project Details” screen for the selection to be added to the quotation file.

8. Control Value Schedule

The software includes a control valve facility to assist in the calculation of the correct valve for the heating and the cooling coil.

9. Calculation Results

All the units permitted within the selection criteria are listed here for the operator to select the unit that they feel is most suitable, with “Design” and “Actual” results displayed.

10. Costing

The costing is broken down into: ‘Materials’, ‘Control Packages’, ‘Extras’ and ‘Bought Out Items’, and each of these areas can be marked-up separately, providing flexibility in your pricing policy. A printout showing the breakdown of the costs is available.

11. Submittals

The printouts will be based upon the examples supplied. Some customisation of the printout layouts will be made in order to give an individual look to the documentation.
