SystemGuru software assists with the design of variable flow heating and chilled water systems, including district heating/cooling, suitable for low carbon heating/cooling sources.
Why use SystemGuru?
Compliance with best practice
SystemGuru checks designs for compliance with relevant best practice guides and codes thereby helping to prevent common system design errors. This gives a better assurance of satisfactory system performance, and is obviously crucial in the event of subsequent claims against the designer.
- Sizes pipes and pumps
- Sizes regulating valves and flow measurement devices
- Sizes automatic control valves
- Optimises variable speed pump control
- Sizes and designs thermal storage buffer vessels
- Integrates low carbon heat sources such as biomass and CHP
- Adapts the design to suit heat interface units
- Calculates hot water simultaneous demand coincidence factors
- Calculates system volumes and sizes expansion vessels
Easy to use
The main program enables users to easily create self-labelling two dimensional schematic drawings linked to self-generating equipment schedules. No out of office training required.
Easy data transfer
Programs are Excel based making it easy to import and export data to or from other files.
By addressing the most complicated aspects of variable flow system design, SystemGuru significantly reduces design time.
The following videos provide a short demonstration of SystemGuru and it’s features.
SystemGuru comprises three separate but complementary programs as listed below.
Variable flow heating and chilled water systems
This program enables users to easily create self-labelling schematic drawings linked to self-generating equipment schedules. The main functions are:
- Pipe sizing
- Pump sizing
- Regulating valve sizing
- Control valve sizing
- Expansion vessel sizing
- Buffer vessel sizing
- Pump speed control optimisation
- Differential pressure control checking
- Allowance for load diversity
Expansion vessels for heating and chilled water systems
This program sizes expansion vessels and prepares a sketch diagram of the system showing gauge pressures across pumps and plant items. The calculation of vessel size, in accordance with BS 7074 parts 2 and 3, is summarised in a separate output page.
Coincidence factors for hot and cold water outlets in multiple dwellings
It is essential that a diversity allowance is made for heating systems that serve multiple hot water heaters. This program models typical usage patterns for different types of project.
These “coincidence factors” can be added to the schematic drawing produced by the variable flow heating and chilled water systems program described above. This enables accurate design of systems using heat interface units for heating hot water.
