Optimising HVAC Systems Towards Greater Efficiency from Devex

danfoss ab-qm valve

The Danfoss AB-QM is a pressure independent balancing and control valve is able to continuously optimise large HVAC systems delivering significant running cost savings. It has been a huge success in Europe, North America, the Middle East and in Asia, and has been the preferred valve specified on several projects throughout Australia including most recently the Barangaroo project in Sydney.

The AB-QM's revolutionary technology combines the compact automatic balancing valve and the control valve into one comprehensive valve structure. AB-QM offers superior temperature control and performance compared to other pressure independent control valves on the market.

One of the most obvious advantages of this valve when compared with conventional two-way valves and manual balancing valves is there are less parts required. This cuts down on installation and commissioning time, takes away the need to do any kind of manual balancing of the installation and reduces calculations significantly. All that is needed is the required flow and the AB-QM will automatically balance the installation immediately after having been installed.

The valve addresses a number of inefficiencies that are common to many large HVAC systems:

  • It eliminates over-pumping throughout the system by only delivering the required flow to the terminal units
  • It keeps the delta T high which maximises the efficiency of the chillers and boilers
  • It provides superior control of room temperatures creating greater comfort all while consuming less energy!

The AB-QM's unique design gives it significant advantages over alternatives:

  • It offers virtually 100% authority over its design pressure range
  • It does this over a large range of settings
  • It is not sensitive to clogging as it does not use cartridge technology
  • It can be adjusted in the field which is great for the contractor should the project requirements change along the way
