AN OPPORTUNITY TO UPGRADE
Matthew Blackmore, Head of Business Development at Armstrong Fluid Technology, provides an update on the most important developments in HVAC pump technology.
Facilities managers often find themselves in charge of the upgrading of heating, ventilation and air conditioning systems for the buildings under their control. Specialist contractors will usually carry out the project. But what key aspects of technical knowledge do FMs need to have, to be able to ensure that the potential energy and cost savings are achieved? This article provides an update on the most important developments in HVAC pump technology.
Facilities managers have long been aware of the advantages of variable speed pumping over the old fixed speed models. Variable speed pumps increase and decrease in line with demand, optimising energy efficiency. Many opportunities are being missed, however, by underestimating the leap forward from controllable pumps to fully integrated intelligent equipment that has been made possible through artificial intelligence and sensorless technology.
Optimising efficiency during the
energy upgrade design stage Today’s intelligent HVAC pumps have a crucial role to play

during the design phase for energy upgrade projects, as well as after implementation. Some latest generation pump models can track and collect data with greater accuracy than traditional flow meters. The embedded software incorporated into these pumps is already used routinely, in many sites, to monitor and report operating conditions and performance of the HVAC systems after the upgrade project is completed.
So why not use the advanced monitoring and reporting capabilities of latest generation pumps to collect the data required to design the new system, instead of using flow meters?
By approaching the energy upgrade in phases, and installing the new pumps ahead of the rest of the project, the pumps themselves can supply the necessary data about the building’s HVAC requirements, with a high degree of detail and accuracy. This assists product selection and system design for the upgrade project, whilst actual, measurable energy savings are demonstrated in real time, throughout this process, to provide a more persuasive business case for
