schematic
Centralising the valves serving a number of terminal devices (eight in this case) makes it much easier to commission and balance them.

Measure to know

With the driving need for building-services and facilities managers to ensure internal environments are maintained in a sustainable way comes several considerations for dealing with waterborne heating and cooling systems. Pressure losses across balancing valves can ruin the control of a variable-flow water system, resulting in loss of internal climate control and accompanying complications such as irritating excess pipe noise. Peter Rees advocates the tried and tested method of differential pressure control and offers some advice on measuring the pressure across the system.

Delivering an effective control system

Doug Robins offers advice on how to realise a control system that will result in a well run and energy efficient building.

hub
Centralised commissioning and balancing of up to eight terminal devices can be achieved from Tour & Andersson’s TA-HUB.

Tour & Andersson has introduced a product that is said to have the capability of reducing installation time by at least 20% and commissioning time by over 50%. Called TA-HUB (to imply hydronic user-friendly balancing) the concept also significantly reduces the time required for the maintenance of hydronic system by bringing together control valves for a number of terminal devices to a single location.

comdronic
In systems with variable-speed pumps and differential-pressure control valves, it is still very important to measure pressures at key points so that pump speeds can be optimised. Electronic manometers can accurately the high pressures that may be encountered.

Maximising energy savings in variable-flow systems

Duncan Selby warns against placing too much reliance on differential-pressure control valves in variable-flow systems.
